广西中稻田約800万亩。桂西百色地区中稻田面积也很大,約占水旱田总数36%。自头年秋收后,到第二年5月份才插秧,整个冬春季都在休閑,同时水肥条件也較差。近年来各地曾經大力发展冬季綠肥,但由于中稻田受水利条件的限制,插秧季节較晚,冬季綠肥种子成熟后,还沒有到插秧季节。因此,冬季綠肥,只能作留种用,而不能提供中稻田的肥料。据此,經过数年来进行的研究試种,覌
About 8000000 acres of rice fields in Guangxi. The area of paddy field in Baise, western Guangxi is also very large, accounting for about 36% of the total number of paddy fields. Since the first harvest in autumn, it was planted in May the following year. All winter and spring were at leisure, and the water and fertilizer conditions were also poor. In recent years, great efforts have been made to develop winter green manures in various places. However, due to the restrictions of water conservancy conditions in Mid-rice fields, the season of transplanting rice is late, and the green manure seeds in winter have not yet reached the season of transplanting. Therefore, the green manure in winter can only be used for the purpose of planting, but can not provide fertilizer for medium-sized paddy field. Accordingly, after years of research trials, 覌
