我场因水稻面积较大,劳力不足,故至今仍采用旱直播栽培方法,亩产一直停留在500斤左右的水平。单产不高的原因,除很大一部分拉腿田没有改造好,田间管理工作跟不上之外,我们认为水稻品种也是一个重要因素。近年来我场所用的品种中,大多为高秆早熟品种,在高肥条件下易倒伏,不但大大影响了产量的提高,同时给机械收割也造成了困难。京引39号水稻在我区插秧栽培,一般亩产都能超千斤。它具有抗病、抗倒、分蘖力强、高产等优良特性,目前在我区确实是一个比较好的品种。但京引39号生长期较长,能不能旱直播呢?1972和1973年我们曾在几个生产队进行了试
My field due to large area of rice, labor shortage, so far still using dry planting method, mu has remained at about 500 pounds level. Yields are not high, except that a large part of the legged fields have not been rebuilt and field management can not keep up. We think rice varieties are also an important factor. In recent years, I used the variety of places, mostly high stalks precocious varieties, prone to lodging in high-fat conditions, not only greatly affected the yield increase, but also caused difficulties in harvesting machinery. Beijing cited No. 39 rice planting in our district cultivation, the general average per kilogram can be produced. It has excellent features such as disease resistance, lodging resistance, strong tillering ability and high yield. It is indeed a good variety in our region at present. However, Jing cited 39 growth period longer, it can dry broadcast it? 1972 and 1973 we had several production team conducted a test
