在修水山区发展中稻+再生稻是在考虑种植双季稻时光温不足和一季稻光温有余,而充分利用山区光温资源,节约生产成本,提高种粮效益,推广的一种水稻耕作方式。2008年以来,通过选择适宜品种+软盘保温育秧+精准抛秧+配方施肥+间歇灌溉+病虫害统防统治+重施芽肥+适留稻桩+加强再生稻管理+机械收获等技术路线,突破亩目标产量800 kg。效益分析表明,中稻+再生稻种植模式每亩收入达到982元,比种植一季稻亩增收435元,比种植双季稻亩增收202元。实现了高产高效的目标。
The development of middle-rice + ratoon rice in Xiushui mountainous area is a mode of paddy rice farming which is under consideration when the light and temperature are insufficient and the light and temperature of one season rice is planted when planting double-cropping rice, while making full use of mountain light and temperature resources, saving production cost, . Since 2008, through the selection of suitable varieties + soft disk insulation seedling + precision throwing seedlings + formula fertilization + intermittent irrigation + pest control + re-sprout fertilizer + rice stubble + strengthening the management of regenerative rice + mechanical harvesting and other technical breakthroughs Mu target output 800 kg. Benefit analysis shows that the planting mode of middle-grade rice and ratooning rice achieves a yield of 982 yuan per mu, an increase of 435 yuan over that of the first-season rice planting and an increase of 202 yuan over the double-cropped rice. Achieved the goal of high yield and high efficiency.
