紫云英丰产利用技术研究

Research on Milk Vetch——How to Increase Its Yield and Make Best use of it

豫南稻区紫云英产草量普遍较低,加之利用不合理,影响水稻产量的提高和肥田改土的效果。试验证明,采取选用紫云英优良品种、施用磷肥、接种紫云英根瘤菌、增加播种量、合理轮作等技术措施,可大幅度提高紫云英产草量。对绿肥的利用,采取适时翻压、晒田、施用石膏、石灰等技术措施,可充分发挥绿肥的肥效,保证水稻的正常生长,从而达到施用绿肥改土肥田、提高水稻产量的目的。

The yield of milk vetch is generally low in the rice-growing area of South Henan province. Irrational application of milk vetch can affect it effects of fertilizing and improving the soil, and thus can cause a drop in rice production. The yield of milk vetch can be raised by a big margin through the introduction of better - strained seed, application of Phosphatic fertilizer and nodule bacteria of milk vetch, close planting, rational crop rolation, etc. Green manure can be used to the best advantage through timely upturning of the plot with milk vetch growing on it, exposure of the upturned plot in the sun,applicat ion of calcium sulphate and lime. In this way, the end to fer tilize and improve the soil will be reached.
