Semi Arid

To improve farmland water use efficiency in the semi-arid area, the field experiment of whole film covering with the spring maize was conducted. The results showed that the whole film mulching (WFM) and the conventional film mulching (CFM) could both improve the maturity effective panicles. The sequence of increasing magnitude was: WFM 2a > WFM 1a> CFM 1a> CK. The CFM could significantly improve grain yield and water use efficiency, however, the WFM could reach to a very significant level. The yield effect between the application of the WFM 2a and the WFM 1a were propinquity, the difference was not obvious. The application of WFM 1~2a was effective maize cultivation pattern in semi-arid region, which was for realizing the water-saving and yield increased purposes.

The Relationship

Achieving optimal balance between maize yield and water use efficiency is an important challenge for irrigation maize production in arid areas. In this study, we conducted an experiment in Xinjiang China in 2016 and 2017 to quantify the response of maize yield and water use to plant density and irrigation schedules. The treatments included four irrigation levels: 360 (W1), 480 (W2), 600 (W3), and 720 mm (W4), and five plant densities: 7.5 (D1), 9.0 (D2), 10.5 (D3), 12.0 (D4), and 13.5 plants m−2 (D5). The results showed that increasing the plant density and the irrigation level could both significantly increase the leaf area index (LAI). However, LAI expansion significantly increased evapotranspiration (ETa) under irrigation. The combination of irrigation level 600 mm (W3) and plant density 12.0 plants m−2 (D4) produced the highest maize yield (21.0–21.2 t ha−1), ETa (784.1–797.8 mm), and water use efficiency (WUE) (2.64–2.70 kg m−3), with an LAI of 8.5–8.7 at the silking stage. The relationship between LAI and grain yield and evapotranspiration were quantified, and, based on this, the relationship between water use and maize productivity was analyzed. Moreover, the optimal LAI was established to determine the reasonable irrigation level and coordinate the relationship between the increase in grain yield and the decrease in water use efficiency.
