1990年我们对棉花施用有机络合微肥的效果进行了初步观察研究。试验结果表明,棉花施用有机络合微肥具有良好的增产作用,亦可获得较高的经济效益。 试验是在123团种子站试验地上进行的。土质为壤质土,总盐含量0.32％,有机质0.96％,碱解氮50ppm,速效磷6ppm。试验分三个处理:A处理为有机络合微肥拌种(用量每亩50克)加喷施(于盛蕾、盛花期各喷一次,每次每亩喷100克);B处理为有机络合微肥喷施(喷期和喷量同A处理);C处理为对照(对棉花不用有机络合微肥,CK)。试验面积0.3亩,重复3次,随机排列。棉花供试品种为69—1。其他栽培措施与大田相同。
In 1990, we conducted a preliminary observation on the effect of applying organic complex fertilizers to cotton. The test results show that cotton with organic complexing micronutrients has a good yield-increasing effect, but also can obtain higher economic benefits. The test was carried out on the 123th seed station test ground. The soil is loamy soil with a total salt content of 0.32%, organic matter content of 0.96%, alkali hydrolysis nitrogen content of 50ppm and available phosphorus content of 6ppm. The test is divided into three treatments: A treatment for the organic compound fertilizer dressing (dosage of 50 grams per mu) plus spray (in Shenglei, full flowering each spray, spray 100 grams per mu); B treatment for organic Complex fertilizers spraying (spraying and spraying the same A treatment); C treatment as a control (cotton without organic complex fertilizer, CK). Test area of 0.3 acres, repeated 3 times randomly arranged. Cotton varieties for the test 69-1. Other cultivation measures are the same as in the field.
