Supporting Technologies of Improved Soybean Varieties and Methods for High-Yield Cultivation
1. Timely sowing: Select varieties with high yield-increase potential adapted to the local area, and sow at the right time. Apply herbicide before sowing soybeans, and apply herbicide again after sowing depending on the weed situation. Sowing time: spring soybeans from late April to early May, sowing depth 5 cm; soil moisture conditions must be given great attention at sowing. The conditions for soybean seed germination mainly include moisture, temperature and oxygen. ① Moisture: seed germination begins with water absorption, so water is an important factor for germination. When seeds germinate, the water absorbed equals 1.21

Detailed Explanation of Agronomic Supporting Techniques for Drip Irrigation Under Plastic Mulch in Cotton
Drip irrigation under plastic mulch is a technique that combines drip irrigation technology with plastic film mulching cultivation technology. Water is supplied through a controllable pipeline system; after water and fertilizer are mixed, they are delivered drop by drop evenly, at set times and in set amounts, moistening the crop root development zone and always keeping the root-zone soil loose and at optimal moisture. It reduces evaporation between crops and improves water use efficiency. 1. Irrigation regime. For subsurface drip irrigation, total water use was 175.48 million cubic meters. Dripping was done 9 times. For precision drip irrigation, total water use was 177.84 million cubic meters. Dripping
