目的:研究喷施叶面肥对青天葵产量的影响。方法:以青天葵为试验材料,分别喷施芸苔素、细胞分裂素和植物基因活化剂3种叶面肥,测量喷施叶面肥后对青天葵的叶片和地下部分生长的影响。结果:喷施3种叶面肥均增加青天葵的叶片厚度、宽度和叶绿素含量,提高球茎的数量和重量;喷施芸苔素叶面肥和基因活化剂叶面肥均对青天葵鲜重和干重分别达到1%极显著相关和5%显著相关。结论:在这3种叶面肥中,喷施芸苔素叶面肥对青天葵增产效果最好。
Objective: To study the effects of spraying foliar fertilizer on the yield of sunflower. Methods: Three kinds of foliar fertilizer, Brassica campestris, Cytokinin and plant gene activator, were sprayed on the leaves of H. pumila and the effect of spraying foliar fertilizers on the growth and development of leaves and underground parts of the sunflower. Results: Spraying three kinds of foliar fertilizer all increased the leaf thickness, width and chlorophyll content, and increased the number and weight of the bulb. Spraying brassica foliage fertilizer and gene activator foliar fertilizer both fresh and dry Remarkably significant correlations of 1% and 5% respectively were found. Conclusion: In these three kinds of foliar fertilizer, sprayed brassinoside foliar fertilizer on the yield of the best.
