The late rice high-yielding and water-saving cultivation technology researched by Yu Songxiang, a researcher of Hunan Province Soil and Vegetal Materials Institute, has recently been successful. This technology uses straw-covered no-tillage combined with shallow-wet cultivation, and can increase effective panicles by 23,000 per 667 square meters (1 acre) compared to conventional cultivation techniques. The effective number of grains per panicle can increase by 18.3 grains in late rice. Within 20 days after inserting, the high temperature and little rain period can reduce the number of irrigation times by 50%, and the irrigation volume can be reduced by 30 cubic meters per 667 square meters.
The technology also has the following advantages: First, straw can be plugged in and harvested, grab the season, and save rake, water and other labor; Second, reduce solar radiation, reduce the mud surface temperature 2-3 °C, conducive to late rice turn green The third is that straw-covered no-tillage can increase soil organic matter, but also can supplement soil potassium, meet the needs of late rice for potassium nutrition, and fourthly, it can avoid nitrogen contending between microorganisms and seedlings in rice straw decomposing process, which is conducive to the early stage of late rice. The growth helps to increase the number of effective panicles and grains per panicle.
