豫南稻区麦茬绿肥栽培利用技术研究

豫南稻区麦茬水稻产量较低,其重要原因是肥料不足。在小麦、水稻两茬作物之间种植一茬绿肥,每亩可获得鲜草1000—3000公斤,这对提高水稻产量,改良土壤,培肥地力有显着效果。麦收后种植绿肥,解决了水稻肥料不足的矛盾,开辟了一条有机肥发展水稻生产的新途径。多年的试验结果表明,柽麻,绿豆,细绿萍等绿肥作物的适应性强,鲜草产量高,适宜于麦茬水稻掩青作底肥。

Techniques for Growing and Utilizng Green Manure Crops after the Wheat Harvest in the Rice - growing Area of the Southern Part of Henan

The yield of rice grown after the wheat harvest is quite low in the southern part of Henan because the manure is not enough. Between the two crods of wheat and rice a green manure crop can be grown.The green grass can be obtained 1,000-3,000kilograms per mu. The grass can make the yield of rice higher, the soil better and more fertjle, etc.. Growing green manure crrp can not only overcome the lack of manure but also open up a new way to develop the rice production bi organic fertilizer. The results of experiments for years habe made known that Crotalaria juncea, Phaseolus radiatus, Sesbaniay cannabina and Azolla filiculoides have high yields and good adaptabilites, and fit to be grown after the wheat harvest.
