水稻直播载培,适应农村新经济体制发展,节省人力物力,提高水稻单产,调整农作物种植结构都有重要的现实意义。一、试验结果与经济效益我们自1981年起,连续进行了五年水稻双季直播栽培技术试验研究,进行了在品种筛选、适宜播种期,以不同播种方式,不同除草剂配合施用,不同肥级和不同播量中设立移栽为对照的最佳组合选配及主要生育指标,大田
It is of great practical significance for rice to live in direct seeding and cultivating, to adapt to the development of a new economic system in the rural areas, to save manpower and material resources, to increase the yield of rice and to adjust the planting structure of crops. First, the test results and economic benefits Since 1981, we conducted a continuous five-year rice double-season direct seeding cultivation technology trials conducted in the screening of varieties, suitable sowing time, with different sowing methods, with different herbicides with different fertilizer Level and different sowing in the establishment of transplanting as the control of the best combination of matching and main fertility indicators, Daejeon
