为进一步了解过磷酸钙(以下简称磷肥)施在水稻上的增产作用,79～80年我们首先在早稻易发僵的练塘等地做了早稻、后季稻磷肥用量试验,发现在青紫土上少量施磷,略有增产效果,但总的来说施与不施效果接近。80年秋播配合市化肥协作网对磷肥进行定位研究,对大小麦、早稻、单季稻实行全年一次施磷肥0、40、80、120斤七种处理连续观察。82年南京土壤所又在我县商榻公社作磷肥用量试验,现将结果小结于后。
In order to further understand the effects of SSP application on rice yield, we first conducted 79 ~ 80 years of early rice, stiff Zitang and other places to do early rice, Feeding a small amount of phosphorus, a slight stimulation effect, but generally do not impose the effect of close to. 80 years of autumn sowing with the City Fertilizer Network positioning of phosphate fertilizer research on the large wheat, early rice, single cropping rice implementation of the annual 0, 40, 80, 120 kg of seven kinds of continuous observation. 82 years Nanjing soil again in my county commune for phosphate fertilizer test, the results are summarized in the post.
