我省有不少稻田多年单纯依靠化肥而不施农肥,土壤有机质匾乏,肥力明显下降,直接影响水稻产量提高。近年来,大洼县几个农场试验水稻与细绿萍间作栽培,取得了成功。这种方法省工、省力、成本低,只要秋翻时把细绿萍翻压在地里,第二年就转化为优质有机质,从而可以逐渐解决稻田板结和地力下降问题。 Many rice paddies in our province rely solely on chemical fertilizers over the years without application of manure, lack of plastid soil organic matter, and marked decline in fertility, which directly affects the yield of rice. In recent years, several farms in Dawa County have experimented with intercropping rice and fine green pingpong for success. This method of labor-saving, labor-saving, low cost, as long as the autumn turn the fine green Ping pressure in the ground, the second year into high-quality organic matter, which can gradually solve the paddy field compaction and decline in soil fertility.
