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

Key points of tea cultivation: selecting improved varieties and reasonable close planting
1. Selecting improved varieties Seeds (seedlings) are the basic means of production in tea cultivation, and any cultivation method is built on the improved varieties of a given period. Since the 1980s, tea cultivation has entirely adopted the close-planted, dwarfed, no-tillage method. Because individual space is reduced and population density increased, it is all the more necessary to match this with suitable improved varieties in order to achieve the desired results. For example, Fuding Dabaicha, Qianmei 101, Qianmei 303 and others are all fine tea varieties suitable for close planting. 2. Collection and
