奉化县三石公社下跸驻二队在研究早稻超历史中,认为山区梯田的主要高产障碍是梯田里坎与外坎水稻生长和产量不平衡的问题。里坎水稻生长极端不良,与外坎相比差异很大。要夺取高产就必须清除这种差异。造成这种差异的原因,一般认为是水冷、阳光不足、土质瘠薄造成的,这是自古以来的认识,从未改变过。所以把这种现实遗留到今天,没有得到改造。我们对当前梯田的现状进行了分析,认为水冷、阳光不足,土质瘠薄等,对水稻生长和
In the study of the history of early rice in the second team of Xiashi in San Shi commune, Fenghua, the main high-yield obstacle in terraced fields in mountainous areas is the problem of rice growth and yield imbalance in ridge ridge and ridge. Ridge rice is extremely poorly-grown, and differs greatly from the ridge. To seize the high yield you must clear the difference. The reason for this difference is generally considered to be water-cooled, lack of sunlight, infertility caused by infertility, which is the understanding since ancient times, has never changed. So this reality left over to today, has not been transformed. We analyzed the status quo of the current terraced fields and concluded that water-cooled, insufficient sunlight and poor soil quality have a negative effect on rice growth and
