自从1980年以来,叶面肥在水稻上应用越来越广泛,叶面肥品种也越来越繁多。但对于种子生产,特别是杂交种子的生产,不可胡乱套用。有些地方有些农户因此得到了适得其反的效果。如王某用高级复合肥调节杂交稻制种花期,结果使偏迟的父本越调越迟。因此,笔者在88、89年试验基础上,92年选定6种叶面肥,在雪峰村杨远峰汕优64制种上继续对比试验。三次重复。以测定各自效果,准确地指导施用,最大限度地发挥它们的功效。通过对催长素(江西产,每亩30g,兑水20kg)、植物生长剂(广州部队产,每亩12ml,兑水20kg)、802(广西植物所产,每亩5g,兑水5kg)、喷施宝(广西产,每
Since 1980, foliar fertilizer has become more and more widely used on rice, and foliar fertilizer varieties are also more and more numerous. But for seed production, especially the production of hybrid seeds, can not be applied indiscriminately. Some farmers in some places have thus obtained counterproductive results. Such as Wang with high-level compound fertilizer to regulate the flowering of hybrid rice, the result of the delayed late paternal off late. Therefore, on the basis of the experiments of 1988 and 1989, the author selected six kinds of foliar fertilizer in 1992 and continued comparative experiments on the seed production of Shanyou 64 in Yangyuanfeng, Xuefeng Village. Repeat three times. To determine the respective effects, accurately guide the application, to maximize their effectiveness. Plant growth agent (Guangzhou military production, 12ml per mu, watered 20kg), 802 (produced by Guangxi plant, 5g per mu, watered 5kg) Spray Bao (Guangxi production, each
