随着生产责任制的落实,花生产区施肥量逐渐加大,地力不断提高,随之出现的就是高产花生倒伏的现象,近两年来群众不断询问解决的办法。喷B_9就是防倒伏的一项重要技术措施。为此谈谈B_9在花生生产上的应用问题。一、喷B_9增产的效果和原因B_9是一种植物生长抑制剂。国内1975年前后,对B_9在花生生产上的应用进行了研究。试验结果表明:凡是喷施时期和浓度比较适宜的,均表现出荚果饱满和结果率、出仁率明显提高的趋势,一般可增产5—17%,其中以增产8%较为普遍。喷B_9增产的原因有以下几个方面:(1)喷B_9后控制了茎枝徒长,协调了营养生长和生殖生长的关系。
With the implementation of the production responsibility system, the amount of fertilizers in flower growing areas gradually increased and the soil fertility increased continuously. As a result, the phenomenon of lodging of high-yielding peanuts occurred. In the past two years, the masses constantly asked for solutions. Spray B_9 is an important technical measure to prevent lodging. To this end, talk about the application of B_9 in peanut production. First, the effect of spraying B_9 and the reasons for the increase B_9 is a plant growth inhibitor. Before and after 1975, the application of B_9 in peanut production was studied. The results showed that all the spraying periods and concentrations were suitable, all showed pod fullness and fruiting rate, the kernel rate increased significantly, generally yield 5-17%, of which yield 8% is more common. Spray B_9 increase in the following reasons: (1) Spray B_9 after controlling the stems leggy, coordinated the relationship between vegetative growth and reproductive growth.
