含氯化肥系列和尿素化肥系列６年定位试验结果表明，含氯化肥肥效高于尿素化肥系列，年平均增产稻谷３．１～２１．１ｋｇ／亩，小麦１０．５～１４．５ｋｇ／亩，油菜籽８．５～１１．５ｋｇ／亩；氮素利用率稻麦油分别提高１０．６～９、４．４～５．３、６．１～０个百分点；种子粗蛋白含量稻麦油分别提高０．７～１．０、１．ｌ～１．３、－０．４～０．０ｍｇＮ／ｋｇ。种子氨基酸含量也均有不同程度提高。不同气候条件、不同土壤、不同作物对含氯化肥肥效可能有很大影响。施用时应注意安全施用原则。
The results of 6-year positioning experiment of series of chlorinated fertilizer and urea fertilizer show that the effect of chlorinated chemical fertilizer is higher than that of urea chemical fertilizer series. The average annual yield of rice is 3.1-21.1kg / mu and wheat is 10.5-14.5kg / Rapeseed 8.5 ~ 11.5kg / mu; Nitrogen utilization rate increased 10.6 ~ 9,4.4 ~ 5.3 and 6.1 ~ 0% respectively; the crude protein content of rice seed oil Respectively, increased 0.7 ~ 1.0,1. l ~ 1.3, -0.4 ~ 0.0mgN / kg. Seed amino acid content also increased to varying degrees. Different climatic conditions, different soils, different crops may have a significant impact on the effectiveness of chlorinated fertilizers. Application should pay attention to the principle of safe use.
