我县自推广晚熟中稻以来,约有三分之一的两季田和浅脚冬水田,常因后期供肥不足而脱肥早衰,影响了产量。根据水稻抽穗后还要吸收全量20%左右的肥料,我们在破口抽穗至齐穗期间采取了追施粒肥的措施,经过几年的试验、示范,收到了良好的效果,促进了水稻增产。实践证明,水稻施粒肥,具有“两增一高”的增产效果,即增粒、增重、产量高。1983年全县在7个点对杂交稻汕优2号进行了施粒肥与不施粒肥的中间试验,结果是:施粒肥的平均亩产1,159.6斤,不施的平均亩产1,049.1斤,施比不施的每亩多收稻谷110.5
Since the promotion of late maturing middle rice in our county, about one-third of the two-season fields and shallow-footed winter paddy fields are often affected by insufficient supply of fertilizers in the late stage, which will affect the yield. According to the rice after heading but also to absorb the full amount of about 20% of the fertilizer, we break the heading to full heading granulation measures taken after years of experiments and demonstrations, received good results, and promote rice yield. Practice has proved that rice grain fertilizer, with “two by one high” yield-increasing effect, that is, grain, weight gain, high yield. In 1983 the county at 7 points on the hybrid rice Shanyou 2 fertilizer and no fertilizer application of the intermediate test, the results are: the average yield per hectare fertilizer 1,159.6 kg, not to apply the average yield of 1,049.1 kg, Shi than Do not impose more than 110.5 acres of rice per acre
