我县晚稻缺肥问题,历年来都没有很好解决。利用海涂种植大米草,是广辟晚稻肥源的一条新途径。每亩涂面能收割大米草地上部鲜叶二至四千斤,可解决一至二亩晚稻基肥的需要。为了探明大米草的肥效对晚稻的增产作用,为今后大面积推广利用大米草作肥料提供依据,我们对大米草进行了肥效试验。现将两年来的试验结果整理如下:
Late rice shortage in our county, over the years have not been well resolved. The use of tartar to grow rice grass is a new way to broaden the source of fertilizer for late rice. Acres coated can harvested rice grass fresh leaves two to four kilograms, to solve one to two acres of late rice base fertilizer needs. In order to prove the effect of rice straw on the yield-increasing effect of late rice and provide the basis for the popularization and utilization of rice straw for large area in the future, we conducted the fertilizer efficiency test on rice straw. Now two years of test results are summarized as follows:
