在坝区稻田中连年稻—麦、稻—油两熟,不利于生产力提高,且土壤有机质含量逐年减少,化肥施用量增加,地力下降。为解决用地与养地的矛盾,达到连年稳产、高产之目的。1987年秋,我站进行油菜套作绿肥探讨试验。一、试验基本情况试验地点选在郑场镇鞍山村,面积1.6亩,在稻谷未收获前7天(9月18日)田已干净皮,在田间行走无脚印,撒播箭舌碗豆种5公斤,同时开好边沟防积水,齐泥割谷收后不翻耕,然后在板田上牵绳打窝、带状移栽油菜,
In the paddy fields of paddy fields even year of rice - wheat, rice - oil two cooked, is not conducive to productivity, and soil organic matter content decreased year by year, increased fertilizer application, decreased soil fertility. In order to solve the contradiction between land use and land conservation, to achieve years of stable production and high yield purposes. The autumn of 1987, I stand for rape sets of green manure experiment. First, the basic situation of the test The test site was selected Anshan Village, Zhengchang Town, an area of 1.6 acres, 7 days before the harvest in the paddy (September 18) field has been clean skin, walk in the field without footprints, Kg, at the same time to open the ditch to prevent stagnant water, Qi mud harvest after the harvest is not plowing, and then pulling in the plate on the nest litter nest, transplanting rape band,
