近两年来我省绿肥生产发展很快。去冬播种紫云英、苕子、黄花苜蓿等专用绿肥达1000万亩。目前各地的绿肥,一般生长良好,估计今春将可收获绿肥三到四亿担,为早造水稻提供大量优质的有机肥,打下粮食大丰收的物质基础。从1964年早造各地施用绿肥的效果来看,稻谷产量普遍获得大幅度的增产,特别是低产地区,增产的效果更大。但也有些地方,因未掌握好施用技术,绿肥压青后水稻并不增产,甚至有减产的现象。怎样才能把它施用得好,从而达到提高水稻产量降低生产成本的目的,是急待研究解决的问题。为此,我们曾在省内各地进行了调查研究,根据群众的经验和我们近年来的工作体会,现就绿肥的施用技术和绿肥压青后水稻的栽培技术问题提出一些初步的意见,以供生产上参考。
Over the past two years, green manure production in our province has developed rapidly. To winter sowing millet, razor clam, alfalfa and other special green manure up to 1000 mu. At present, green manures are generally growing well. It is estimated that green manures from 300 to 400 million Tam can be harvested this spring, providing a large quantity of high-quality organic fertilizer for early rice cultivation and laying a material foundation for the harvest of grain. As early as 1964, the effect of applying green manures around the country was made. As a result, the yield of paddy was generally increased sharply, especially in low-yielding areas, and the yield increase was even greater. However, in some places, because of the lack of application of technology, green rice does not increase yield even after greening, and there is even a decrease in yield. How to apply it well, so as to achieve the purpose of increasing the output of rice and reducing the production cost, is an urgent problem to be solved. To this end, we have conducted surveys and studies all over the province. Based on the experience of the masses and our work experience in recent years, we have put forward some preliminary opinions on the application technologies of green manures and the cultivation techniques of paddy rice after green manure pressing for Production reference.
