在六十年代,随甘兰型油菜的推广,我县出现了油莱“花而不实”问题。中国农科院油料研究所研究证明,土壤有效硼缺乏是导致这一生理性病害的根本原因,并提出了喷施硼肥的防治措施,促进了甘兰型油菜的发展。为研究有效的施硼方法,我们连续三年进行了五次油菜硼肥试验,结果表明,硼砂作油菜底肥对提高产量有明显的增产作用。1978—1979年度全县推广4000余亩,效果较好。据五个点的对比试验,底施硼砂比不施硼砂增产10.3
In the 1960s, with the promotion of Brassica napus, we found a problem with “raspberry” in the county. Research Institute of Oil Crops, Chinese Academy of Agricultural Sciences has proved that the lack of available boron is the root cause of this physiological disease, and put forward the prevention and treatment of spraying boron fertilizer to promote the development of Brassica napus. In order to study the effective application of boron method, we conducted five times of rape boron fertilizer test for three consecutive years. The results showed that borax as rapeseed fertilizer has a significant increase in yield. 1978-1979 to promote the whole county more than 4,000 acres, the effect is better. According to the comparison test of five points, the bottom borax production increased 10.3% compared with no borax
