“周年养萍”是指在早晚稻田采用“宽窄行双龙出海”的插秧方式,套养红萍,做到既不影响或少影响水稻产量,又可不断繁殖红萍,达到粮肥双高产的目的。根据今年初步试验结果,早晚稻和早季红萍的产量还比较高,晚季养萍有的点不很成功,但改养水浮莲效果比较好,除要继续研究容易普遍掌握的晚稻养萍技术外,目前在生产上“周年养萍”田晚季改养水浮莲有一定的意义。一、问题的提出近年来,由于复种指数和单产的不断提高,高产耐肥品种的推广,对肥料的要求越来越多。群众的经验:“亩产千斤稻,亩施百担肥。”从我们调查的结果:亩产千斤稻,要亩施
“Anniversary of Ping ” refers to the early and late paddy fields using “width line Ssangyong sea ” transplanting method, nesting red ducklings, so as not to affect or less affect the yield of rice, but also continue to breed red duckweed, to achieve food The purpose of fertilizer double high yield. According to the preliminary results of this year’s trial, yields of early and late rice and early autumn red clover are still relatively high. Some of them were not very successful in the late season, but the effect of raising water hyacinth was relatively good. In addition to continuing to study the late-growing rice larvae technology, At present, the production of “Anniversary of the raising of Ping ” field late autumn raising floating lotus has a certain significance. First, the issue raised In recent years, due to the multiple cropping index and continuous improvement of yield, high-yield varieties to promote the promotion of more and more fertilizer. The experience of the masses: “mu per kilogram of rice, mu Shi Baoyu fat. ” From our survey results: mu yield of rice, to acres of facilities
