七十年代以来,随着高产稻种推广,栽培技术改进和化肥大量施用,使早稻单产达到千斤上下,但对稻田养萍的增产效应却引起了争议。因稻田套养绿萍必然引起水稻生态条件的改变,对水稻器官的生育影响如何呢?所以研究高产田套养的绿萍的稻萍栽培技术,以期达到高产、稳产,降低成本,培养地力的经济效益,是目前生产中急待解决的问题。 Since the 1970s, with the promotion of high-yielding rice varieties, improvement of cultivation techniques and large-scale application of chemical fertilizers, the yield of early rice has reached the upper and lower levels, but the yield-increasing effect on raising rice in the paddy field has caused controversy. Therefore, it is necessary to study the effects of paddy field cultivation of Lupin on rice paddy cultivation in order to achieve high yield, stable yield, reduce costs and cultivate fertility Economic efficiency is an urgent issue in production.
