大麦连作稻一年三熟,是增加复种指数,获得全年增产的有效途径。为摸索其高产规律,进一步提高产量水平,去年杭州市农科所栽培组进行了稻麦三熟的高产试验,共试10.38亩,平均亩产1894.5斤,其中3.4亩亩产达2002.9斤。遵照毛主席“要认真总结经验”的教导,现就稻麦三熟高产栽培中的几个技术问题,谈点粗浅认识,供大家参考: Barley, rice and rice, cooked three times a year, is to increase the crop index, an effective way to increase annual output. In order to explore the law of its high yield and further improve the yield level, last year, Hangzhou Agricultural Science and Cultivation Group conducted a high-yielding trial of rice and wheat three trials, a total of 10.38 mu, an average of 1894.5 kg per mu, of which 3.4 mu per mu reached 2002.9 kg. In accordance with the teaching of Chairman Mao, “we should conscientiously sum up experiences”, we are going to make some brief comments on several technical issues in the high yielding cultivation of rice and wheat, for your reference.
