为了提高红花草种子产量,我们于1971年开始进行红花喷硼试验,结果如下: 1.喷硼对红花草种子的增产效果 实验证明,喷硼对提高红花草种子产量效果很好。据1971一1973年在十里铺大队和五里农科所试验,在开花前和始花期各喷一次0.1%的硼砂溶液,比对照(未喷硼)增产59%;在始花期喷一次,比对照增产28%。1974年盘古垱大队红花草喷硼面积87.2亩,亩产种子78.2斤,比历史上最高产量的1970年亩产50.7斤增产34.6%;十里铺大队喷硼面积120亩。平均亩产种子71.6斤,比历史上最高产量的1971年亩产54斤增产32.5%。同时还出现不少
In order to improve the seed yield of safflower, we started the safflower spraying experiment in 1971. The results are as follows: 1. The effect of spraying boron on the yield of safflower seed The experiments show that spraying boron has a good effect on improving the yield of safflower seed. According to the experiments conducted in Shiliupu and Wuliongye from 1971 to 1973, 0.1% borax solution was sprayed before flowering and flowering respectively, yielding 59% more than that of the control (without boron spraying); spraying at the initial flowering period Control increased 28%. 1974 Panggutong brigade spraying boron flowers area of 87.2 acres, 78.2 kilograms per mu of seeds, higher than the highest yield in history in 1970 50.7 kg per mu yield 34.6%; Shilipu brigade spraying boron area of 120 acres. The average yield per mu is 71.6 kilograms, an increase of 32.5% over the yield of 54 tons in 1971, the highest output in history. At the same time also appeared a lot
