Film Mulching

Summary Plastic film (PF) mulching is widely applied in agriculture to improve water-use efficiency (WUE) and crop production. However, without efficient recovery, the residual plastic fragments in arable land threaten soil health and food security. Degradable films are generally considered as alternatives to conventional PF to mitigate PF pollution. A 2-year field experiment was conducted in 2016 and 2017 to evaluate the effects of various film mulching treatments (conventional PF mulching, transparent degradable film (TDF) mulching, and black degradable film (BDF) mulching, and no mulching) on soil water availability and summer maize yield in the North China Plain (NCP). Soil moisture, soil water storage, water use, and grain yield were recorded. Below 20 cm depth, soil moisture and soil water storage were higher in film mulching than in no mulching. Conventional PF mulching yielded the best water conservation, especially from sowing to jointing. TDF and BDF were similar in their regulation of soil moisture. Comparing to no mulching, conventional PF and degradable transparent film significantly reduced maize grain yield by 15.4 and 8.0% (average over 2 years), and reduced WUE by 9.4 and 7.8% (average 2 years), respectively. The observed reduction of grain yield in transparent film mulching might be caused by excessive soil temperature, especially at vegetative stages, which potentially accelerates crop senescence. Black film mulching reduced the soil cumulative temperature and prevent crops from being overheated. As consequence, grain yield and WUE of summer maize under BDF covering were significantly increased by 11.1 and 15.6%, respectively, over the 2 years. Therefore, we suggest that BDF can be used to replace conventional plastics to improve crop yield and control environmental pollution in the NCP.

Water resources in the North China Plain (NCP) are limited, so it’s in urgent need to optimize deficit by irrigation for sustainable winter wheat production in this area. Winter wheat grain yield (GY), contribution of dry matter (DM) remobilization to GY (CDMRG), and water use efficiency (WUE) were investigated in NCP. Compared with non-irrigation treatment, irrigated with 60 mm each at the winter wheat jointing stage (JS) and heading stage (HS) achieved reasonable winter wheat GY and WUE. Compared with irrigation with 120 mm only at JS and irrigation with 40 mm each at JS, HS, and milking stage (MS) of winter wheat, irrigation with 60 mm each at JS and HS provided the highest CDMRG, which resulted to the highest GY and WUE; this result was mainly due to a significant increase of the spike numbers (SN) per m2. The results suggest that in the NCP, in order to achieve reasonable GY and WUE, winter wheat should be irrigated with 60 mm each at JS and HS.

Film Mulching

Aiming at reducing agricultural pollution caused by plastic film and increasing soil moisture and water use efficiency (WUE), the field experiments were conducted to investigate the effects of re-used plastic film mulching on soil moisture, sunflower’s yield and water use efficiency by compared with new plastic film mulching and bare field in Hetao area, China. The results showed that, soil water of re-used film mulching increased at different degree. Compared with bare field and new film mulching, soi1 moisture of re-used film were higher significantly 1.5 percentage points in 0-100 cm, and especially 1.9 or 2.6 percentage points in 0-10 cm during sunflower’s growth stage. Soil water of re-used film was more than that of bare field 24.8 mm (in 2010) and 33.0 mm (in 2011) before seeding, and 21.6mm (in 2010) and 24.5mm (in 2011) at harvest when soil water was replenished to same level for each treatment before sowing. Meanwhile, the grain yield of re-used film was higher significantly than that of bare field 11.4% (in 2010) and 16.8% (in 2011), and WUE of re-used film was higher significantly 15.7% (in 2010) and 22.7% (in 2011) respectively, no significant with new film. So it was worth to apply re-used film to agriculture production for improving the soil moisture, enhancing water use efficiency and increasing the yield of sunflower. We suggest that the application of re-used film mulching is a suitable soil management practice for increase water and WUE in Hetao area or other areas with similar conditions.

Aiming at the problems of shallow effective soil layering and low utilization rate of precipitation in the North China Plain. The effects of different subsoiling stages on soil physical properties and water use in winter wheat/summer maize fields were studied. Three kinds of tillage treatments were studied: rotary tillage to a depth of 15 cm in October and no-tillage in June (RT), rotary tillage to a depth of 15 cm in October and subsoiling to 35 cm in June (ST-J), subsoiling to a depth of 35 cm in October and no-tillage in June (ST-O). Changes in soil bulk density and soil compaction were consistent over two seasons. Compared to RT, in the 10–50 cm soil layer, ST-J and ST-O decreased the average soil bulk density by 6.18% and 5.66%, respectively, and the soil compaction in the 10–60 cm layer was reduced by 17.89% and 20.50%. ST was improved soil structure and increased the water content of deep soil. The water use efficiency (WUE) of ST-J and ST-O increased by 4.73% and 14.83%, respectively, and the maize yields by 2.90% and 11.35%, respectively. Considering the WUE and maize yields, it was considered that ST-O is more suitable for tillage in the North China Plain.
