塑料大棚春番茄熊蜂授粉技术初探

Effect of Specific Fertilizer on Poa annua Leaf Growth and Chlorophyll Content

塑料大棚春番茄应用熊蜂授粉,不仅可以促进坐果、提高产量,更为重要的是,可以避免激素处理带来的化学污染问题,改善果实品质,有利于无公害蔬菜生产。作者通过两年的试验研究,初步总结出塑料大棚春番茄的熊蜂授粉技术,并对其效益进行科学分析。

Taking 4 years Poa annua as experimental material, the effect of specific fertilizer on leaf growth and chlorophyll content was studied. The results indicated 135.93kg specific fertilizer per ha can most significantly extent increase the leaf length and width with excellent growth. The treatment fertilized 116.47kg specific fertilizer per ha exhibited slender leaf. The treatment fertilized 97.03kg specific fertilizer per ha showed shorter and wider leaf than the other treatments. The leaf chlorophyll contents were in sequence as ZH3, ZH1, ZH2, CK. The variance analysis indicated ZH3 was significantly higher than the other three treatments. So 135.93kg specific fertilizer per ha is the optimal application rate for 4 years Poa annua.
