我省近几年来,随着耕作制度的改革,耕地复种指数不断提高,地力消耗较大,在原有施肥水平下,土壤肥力势难满足多造农作物的需要,单位面积产量的继续提高,必将受一定限制,其中尤以晚造稻田缺肥情况比较突出,影响着整个农业的大上快上。如何因地制宜,就地取材,通过间套各种固氮绿肥作物,以田养田,迅速恢复和培肥地力,达到粮食高产稳产,是当前急待解决的现实问题。省内外先进地区实践证明,红萍是一种适应性广,繁殖快,产量高,肥效好,四时可养,全年可用,不存在与其他作物争地矛盾的
In recent years, with the reform of the tillage system in our province, the index of cropland multiplication has been continuously improved and the geoecology consumption has been greatly increased. Under the original fertilization level, the soil fertility is hard to meet the needs of more crops and the output per unit area continues to increase. Due to certain restrictions, especially in late rice fields are more prominent lack of fertilizer, affecting the entire agriculture faster. How to adapt to local conditions, obtain materials locally, and intercropping various kinds of nitrogen-fixing green manure crops so as to quickly restore and fertilize fertility so as to achieve high and stable grain yield are the immediate problems to be solved urgently. The practice in the advanced areas inside and outside the province proves that Hongping is a kind of plant with wide adaptability, fast propagation, high yield, good fertilizer effect, four-year support, annual availability and no conflicts with other crops
