1971年我站开始在红花草田试喷“九二○”,1972年推广全场23,000余亩,1973年喷施面积达50,000余亩,1974年至69,000余亩。大面积喷施“九二○”后,所有处理田块的红花草产量都表现增产。1972年,全场30个试验点的测产结果,红花草鲜草增产幅度,多数为15—35％,低者亦在10％左右。 “九二○”喷红花草后,其作用表现在:苗干重增加、檀株增高,分枝增多、叶数增加、根瘤数增加、根系发达。见表1。 在红花草喷施“九二○”的实践中,发现增产的效果与下列因素有关。
In 1971, I started to test the “920” test in the safflower grass field. In 1972, I promoted more than 23,000 acres of the audience. In 1973, I sprayed more than 50,000 acres of land from 1974 to 69,000 acres in 1974. After spraying “920” on a large scale, the yield of all flowers on the plots has been increased. In 1972, the test results of the 30 test points audience, the yield of fresh flowers, mostly 15-35%, the lower is about 10%. “920” after the spray crocus, its role in the performance: increased dry weight of seedlings, sandalwood increased, branches increased, the number of leaves increased, nodules increased root system. See Table 1. In the practice of red flowers spray “9 20”, and found that the effect of increased production with the following factors.
