Family Farms

In the process of rapid economic development, an innovative mechanism for agricultural management, support for the functioning of family farms will contribute to the efficiency, large-scale, intensive agricultural production and economic benefits of China. The purpose of the article is to combine theoretical analysis with practical, in terms of management, scale and efficiency of family farms, to find the optimal ratio for Henan Province. Effective organization and management is an important factor to promote the development of any enterprise or subject. As a new agricultural management subject, family farms play a very important role in China's agricultural development. Appropriately sized family farms can effectively realize the optimal allocation of resource elements, which is in line with the current needs and policy objectives of China's modern agricultural development. As the main body of new agricultural management, family farm is an effective organizational form to promote agricultural intensive, professional, large-scale and modern management. After many years of research, Chinese and foreign scholars have indeed confirmed the importance of the contribution of family farms to the agricultural sector of the economy and believe that they are typical representatives and, of course, an indispensable component in promoting agriculture. On the basis of theoretical and in combination with empirical analysis, this study proved that under modern conditions of production organization, not all family farms have high efficiency. When family farms exceed their business capacity, they also lack production efficiency. At the same time, it should be noted that the most productive subjects of agriculture today are family farms of the appropriate scale. According to the results of the study, it was determined that a family farm with a land area of 60-110 Mu, is the most productive agricultural entity in this segment. In order to further implement, proposals and methods for improving the efficiency of family farms in Henan Province have been proposed.

Oasis agriculture in arid areas faces the constraints of scarce resources and a fragile ecological environment. Improving agricultural production efficiency is the key solution. However, there are few studies analyzing the relationship between farmers’ production efficiency and planting scale from a micro-empirical perspective. Herein, we study the seed-producing corn growers in Zhangye city, and supplement special survey data with national input–output survey data. We use data envelopment analysis to measure agricultural production efficiency, and tobit regression to calculate the marginal effects of factors affecting production efficiency on farms of different scales. The results show that production efficiency is greater for large-scale farmers than for small-scale farmers. Duration of technical training, education time of laborers, planting income, and productive expenditure are significantly positively correlated with production efficiency. Average age of farmers and the amount of pesticide and fertilizer use are significantly negatively correlated with production efficiency. Off-farm activities improve the production efficiency of small-scale farmers but inhibit it for medium- and large-scale farmers. Differences exist in marginal impacts for different scales of farmland. We conclude that expanding the scale of family farms and optimizing human capital are effective for improving agricultural production efficiency in arid oasis areas.

Abstract Background Biological alternatives to pesticides in agriculture do not harm non-targets organisms including natural enemies of insect pests. Experiments were conducted at sugarcane fields during 2015 to 2019 to assess large scale biocontrol practices, involving inundative releases of trichogrammatids against lepidopteran borers in comparison to conventional chemical-based farmers’ practice. Main body Eight releases each of Trichogramma chilonis Ishii and Trichogramma japonicum Ashmead were made at 50,000 ha−1 at 10 days interval for the management of sugarcane stem borer, Chilo infuscatellus Snellen and the sugarcane top borer, Scirpophaga excerptalis (Fabricius) (Lepidoptera: Crambidae), respectively. Likewise, 10–12 releases of T. chilonis were made at 50,000 ha−1 at 10 days interval for the management of sugarcane stalk borer, Chilo auricilius Dudgeon (Lepidoptera: Crambidae). The biocontrol intervention was compared with farmer’s practice (chemical control) in managing these borers. The results showed that farmers’ practices and biocontrol treated fields resulted in a lower incidence of C. infuscatellus (1.1, 2.9%) and S excerptalis (1.7, 3.9%) than the untreated control fields, wherein the mean per cent incidence of these borers (6.8, 8.5%) was significantly higher. The incidence of C. auricilius was also lower in augmented fields (2.8%) than untreated fields (7.3%). The yield data indicated that farmers adopting biocontrol practices were able to get comparable yield and benefit: cost ratio than farmers’ practice, both being better than untreated control. Moreover, in biocontrol fields, parasitism rate on the factitious host, Corcyra cephalonica Stainton cards was estimated. Conclusion Thus, the study highlights the significance of adoption of biocontrol-based technology over a long run to provide sustainable system of sugarcane insect pest management and economic benefits to the stakeholders.

American Agriculture

Early in 2013 China’s Party Central sounded the call for developing so-called “family farms.” A great deal of discussion ensued, in which the dominant view has been to call for developing scale economies in “family farming” through greatly increased transfers of land, in the belief that large-scale farms would help raise both labor and land productivity. The slogan used, “family farms,” is borrowed from American rhetoric and reflects the way American agriculture is mistakenly imagined by many people. This article demonstrates that such a vision runs counter to the logic shown by the history of agricultural modernization throughout the world. It mistakenly tries to force China’s reality of “lots of people and little land” into an American model predicated on its opposite of “lots of land and few people,” and it mistakenly tries to apply economic concepts based on the industrial machine age to agriculture. The vision/policy is also based on a misunderstanding of the realities of contemporary American agriculture, which has long since come to be dominated by agribusiness. The determinative logic in American agricultural modernization has been to economize on labor, in contrast to the path of modernizing development that has already taken hold in practice in Chinese agriculture of the past 30 years, in which the dominant logic has been to save on land, not labor, in what I term “labor and capital dual intensifying” “small and fine” agriculture. The American “big and coarse” “model” is in reality utterly inappropriate for Chinese agriculture. It also runs counter to the insights of the deep and weighty tradition of scholarship and theorizing about genuine peasant family farming. The correct path for Chinese agricultural development is the appropriately scaled, “small and fine” genuine family farms that have already arisen quite widely in the past 30 years. This article is in English. 中共中央于2013年年初提出要发展“家庭农场”，之后全国讨论沸沸扬扬，其中的主流意见特别强调推进家庭农场的规模化，提倡土地的大量流转，以为借此可以同时提高劳动和土地生产率。其所用的口号“家庭农场”是来自美国的修辞，背后是对美国农业的想象。本文论证，这是个不符合世界农业经济史所展示的农业现代化经济逻辑的设想，它错误地试图硬套“地多人少”的美国模式于“人多地少”的中国，错误地使用来自机器时代的经济学于农业，亟需改正。它也是对当今早已由企业型大农场主宰的美国农业经济实际的误解。美国农业现代化模式的主导逻辑是节省劳动力，而中国过去三十年来已经走出来的“劳动和资本双密集化”小而精模式的关键则在节省土地。美国模式不符合当前中国农业的实际，更不符合具有厚重传统的关于真正的小农经济家庭农场的理论洞见。中国近30年来已经相当广泛兴起的适度“小而精”规模的真正家庭农场才是中国农业正确的发展出路。

SummaryThe factor V (FV) mutation Q506 that causes resistance to activated protein C (APC) is the genetic defect associated most frequently with venous thrombosis. The laboratory diagnosis can be made by DNA analysis or by clotting tests that measure the degree of prolongation of plasma clotting time upon addition of APC. Home-made and commercial methods are available but no comparative evaluation of their diagnostic efficacy has so far been reported. Eighty frozen coded plasma samples from carriers and non-carriers of the FV: Q506 mutation, diagnosed by DNA analysis, were sent to 8 experienced laboratories that were asked to analyze these samples in blind with their own APC resistance tests. The APTT methods were highly variable in their capacity to discriminate between carriers and non-carriers but this capacity increased dramatically when samples were diluted with FV-deficient plasma before analysis, bringing the sensitivity and specificity of these tests to 100%. The best discrimination was obtained with methods in which fibrin formation is triggered by the addition of activated factor X or Russell viper venom. In conclusion, this study provides evidence that some coagulation tests are able to distinguish carriers of the FV: Q506 mutation from non-carriers as well as the DNA test. They are inexpensive and easy to perform. Their use in large-scale clinical trials should be of help to determine the medical and economic benefits of screening healthy individuals for the mutation before they are exposed to such risk factors for venous thrombosis as surgery, pregnancy and oral contraceptives.

Under the influence of COVID-19, the economic benefits of shale gas development are greatly affected. With the large-scale development and utilization of shale gas in China, it is increasingly important to assess the economic impact of shale gas development. Therefore, this paper proposes a method for predicting the production of shale gas reservoirs, and uses back propagation (BP) neural network to nonlinearly fit reservoir reconstruction data to obtain shale gas well production forecasting models. Experiments show that compared with the traditional BP neural network, the proposed method can effectively improve the accuracy and stability of the prediction. There is a nonlinear correlation between reservoir reconstruction data and gas well production, which does not apply to traditional linear prediction methods

Greenhouse gas emissions must be cut to limit global warming to 1.5-2C above preindustrial levels. Yet the rate of decarbonisation is currently too low to achieve this. Policy-relevant scenarios therefore rely on the permanent removal of CO<sub>2</sub> from the atmosphere. However, none of the envisaged technologies has demonstrated scalability to the decarbonization targets for the year 2050. In this analysis, we show that artificial photosynthesis for CO<sub>2</sub> reduction may deliver an efficient large-scale carbon sink. This technology is mainly developed towards solar fuels and its potential for negative emissions has been largely overlooked. With high efficiency and low sensitivity to high temperature and illumination conditions, it could, if developed towards a mature technology, present a viable approach to fill the gap in the negative emissions budget.<br>

Optimal Allocations

With the development of science and technology, the degree of agricultural mechanization is getting higher and higher. Agricultural machinery is an important support for the development of agricultural modernization. Optimizing the allocation of agricultural machinery is conducive to improving agricultural production efficiency and economic benefits. In this paper, mathematical modelling method is mainly used in the analysis and optimization of agricultural machinery configuration. By determining the objective function and constraint equation, combined with the actual situation of Xinjiang Production and Construction Corps, the linear programming model and workload model of agricultural machinery and equipment optimization are established. Finally, the actual number of agricultural machinery and equipment and the number of optimal allocations of Xinjiang Production and Construction Corps farm were compared. The effectiveness of the optimization model is verified by comparing the optimized agricultural machinery equipment with the actual equipment. The results show that the optimized equipment model has good optimization effect. On the basis of reducing the number of agricultural machinery and equipment, the matching rate of agricultural machinery is improved, and the operation cost of agricultural machinery is effectively reduced. It is hoped that this study can provide certain reference and reference for the optimization analysis of agricultural machinery and equipment based on mathematical modelling.
