在冬绿肥——早稻轮作中,把磷肥施用于绿肥作物上,通过“以磷增氮”扩大磷肥肥效,目的是为了提高后作水稻的产量,增加磷肥的经济效益。因此,除了要研究绿肥的经济有效施用磷肥技术,以便最大限度地增加绿肥产量,为早稻提供较多肥料外。同时,还必须研究“以磷增氮”后对水稻的实际增产效果,以及在这个轮作制中如何合理分配使用磷肥,才能收到最大的经济效益。关于冬绿肥施用磷肥技术作者等已在前一报告进行初步论述。这里拟就1964年冬至1965年早造惠阳镇隆磷肥样板,冬种苕子、紫云英——早稻轮作磷肥试验的一些结果,对上述有关问题进一步进行讨论。
In the winter green manure - early rice rotation, the phosphate fertilizer applied to the green manure crops, through the “phosphorus by nitrogen” to expand fertilizer efficiency, the purpose is to improve post-production of rice and increase the economic benefits of phosphate fertilizer. Therefore, in addition to studying the economical and effective application of green manure to phosphate fertilizer technology in order to maximize green manure production and provide more fertilizer for early rice, At the same time, it is also necessary to study the actual production increase effect of rice after increasing phosphorus by nitrogen and how to allocate the use of phosphate fertilizer reasonably in this rotation system in order to receive the maximum economic benefits. The authors on the application of phosphate fertilizer to winter green manures have been tentatively discussed in the previous report. Here are some of the results from the 1964 Winter Solstice to 1965 early Huiyang Zhenlong Phosphate Fertilizer Model, Winter Seed, Ziyun Ying - early rice rotation for phosphate fertilizer, the above issues to be further discussed.
