红花草绿肥是农业生产上一项主要肥料。为了进一步提高红花草产量,根据“九二○”植物生长刺激素在许多农作物上表现出能促进植株生长和根瘤作物需要较多的磷钾肥的特点,我们在一九七五年三月二十一日红花草始花期,进行了喷施“九二○”和施磷肥对比试验,获得了显著的增产效果。在一块红花草田里,取一边面积0.32亩喷“九二○”,一边0.2亩不喷,“九二○”用量为1克兑清水67斤,结果喷“九二○”的亩产鲜草2930斤,比不喷的亩产2600斤增产12.6％。在另一块红花草田里,取一边面积0.45亩施磷,一边0.21亩不施,磷肥用量为每亩过磷酸钙7斤兑清水100斤泼施,结果施磷肥的亩产鲜草2910斤,比不施的亩产2310斤增产20.3％。
Safflower green manure is a major fertilizer on agricultural production. In order to further increase the yield of safflower, according to the characteristics of the “1990” plant growth-stimulating hormone on many crops that can promote plant growth and the need for more phosphorus and potassium fertilizer on nodulated crops, we published a report on March 20, 1975 On the first day of the first flowering season, conducted a spray “920” and phosphate fertilizer comparative test, access to a significant increase in yield. In a safflower grass field, take an area of 0.32 acres spray “9 20”, while 0.2 acres do not spray, “920” amount of 1 gram of water against 67 pounds, the results spray “920” per mu of fresh 2930 kg of grass, an increase of 12.6% compared with 2600 kg of non-sprayed mu produce. In another safflower grass field, take an area of 0.45 acres of phosphorus, while 0.21 acres of non-Shi, phosphate fertilizer per acre of 7 kg against water, 100 pounds pouring Shi, the results of phosphate fertilizer per mu 2910 kg of fresh grass, 2310 kg per mu than no increase in yield 20.3%.
