土变田是扩大水稻栽插面积,提高单产,增加粮食产量的有效途径。但以往搞土变田的由于措施不力,当年栽秧后都普遍发生秧根发黑、叶片发黃,轉青慢、不发蔸、倒死不活,以致产量很低。关一年亩产一般只有几十斤或百把斤,第二年也不过二、三百斤,要到第三年才能达到400斤左右的产量,而且还要稳定几年才能赶上一般田。今年金鈡大队打破旧框框,采用先进技术措施,新开89.7亩田,平均亩产可达654斤,其中亩产400斤以下的有1.6亩占1.8%,400~500斤 Variation of soil is an effective way to expand rice planting area, increase yield and increase grain yield. But in the past to engage in soil change field due to ineffective measures, when the year after planting seedlings are generally black, leaves yellow, turn slow, not flies, died, resulting in low yields. The average output per mu is only about 10 kilos or 100 kilos in one year. However, in the second year, only two or three kilos will reach the output of about 400 kilos in the third year, and it will take a few years to catch up. . This year, Jinlian Brigade has broken the old framework and adopted advanced technical measures to open 89.7 mu of newly opened land, with an average yield of 654 kilos per mu, of which 1.6 mu (1.8 mu) and 400-500 kilos
