1980年采用田间、盆栽试验并结合室内分析进行肥效和施用技术研究.结果表明;氯离子对蔬菜体内NO_3—N的含量有明显抑制作用,适量氯的存在对蔬莱吸收H_2PO_4~-和K~+的吸收无不良影响;氯离子浓度对几种蔬菜的敏感性以菠菜>甘兰>青椒、萝卜.常量氯磷铵对四种蔬菜的产量和品质均无不良影响;氯磷铵对棉花、大豆、花生、甘兰、青椒、苹果的肥效,与尿素磷铵或尿素+普钙基本相等.它对这些作物的品质无不良影响;氯磷铵对大豆的最高施肥量为29.4公斤/亩,棉花的最高施肥量为36.8～45公斤/亩,以作基肥或施在种下5cm左右为宜.
In 1980, field experiments and pot experiments were carried out to study the effects of fertilization and application of nitrogen and phosphorus in vegetables. The results showed that chloride ion had a significant inhibitory effect on NO_3-N content in vegetables, and the presence of adequate amount of chlorine had significant effects on the absorption of H_2O_4 ~ + The absorption of chloride has no adverse effect on the sensitivity of several vegetables with spinach> cabbage> green pepper, radish. The constant amount of ammonium chloride has no adverse effect on the yield and quality of the four vegetables; ammonium chloride on cotton, Soybeans, peanuts, cabbage, green peppers and apples have the same fertilizer efficiency as urea ammonium phosphate or urea + calcium supplements, and have no adverse effect on the quality of these crops. The highest application rate of ammonium chloride to soybean is 29.4 kg / mu, The maximum amount of cotton fertilizer 36.8 ~ 45 kg / acre, as a base fertilizer or applied in the planting of about 5cm is appropriate.
