近年来,随着春粮、油菜面积的逐年扩大,冬季绿肥面积随之缩小,使稻田缺乏有机养料的矛盾渐趋突出。为此,我们于1984—1985年度进行了“绿肥稻板麦”即紫云英(前作晚粳稻)间种大麦(免耕)的试验。试验结果表明,绿肥稻板麦这种栽培方式不但省工省本效益高,而且能促进土壤良性循环,从长远利益考虑也是十分有利的。一、粮、肥兼顾,效益高从试验结果看,“紫云英=大麦”平均亩产大麦194.3斤,紫云英(地上部分)2,860.7斤;净大麦(对照1)平均亩产361.1斤;净紫云英(对照2)平均亩产(地上部分)3375.0斤。可以从两个对照的结果
In recent years, with spring grain, rapeseed area has expanded each year, winter green manure area will be reduced, so that the lack of organic nutrients in paddy contradictions become increasingly prominent. To this end, we conducted a trial of “green manure rice planter”, barley (no-till) between Astragalus (formerly late japonica) in 1984-1985. The test results show that the cultivation mode of green manure rice and paddy is not only highly effective in saving labor but also can promote the virtuous cycle of soil, which is also very beneficial in the long-term interest. First, the grain, fat balance, high efficiency From the test results, “Astragalus = barley” average yield of 194.3 pounds of barley, Astragalus (aerial part) 2,860.7 kg; net barley (control 1) average yield of 361.1 kg; Net mean score (control 2) The average yield per mu (above ground) is 3375.0 kg. The results from both controls can be obtained
