不同生长时期叶面喷施硼肥对辣椒植株生长发育的影响

Effects of Foliar Spraying Boron Fertilizer on Peppers' Growth at Different Growth Periods

为了探索叶面施用硼肥对辣椒植株生长发育的影响,开展在辣椒现蕾期和初花期叶面喷施不同浓度硼肥的田间试验。试验结果表明,在辣椒的现蕾期和初花期叶面喷施不同浓度的硼肥均能改善辣椒植株的生长,提高辣椒的挂果数,其中,辣椒现蕾期喷施更有利于增加挂果数,在初花期喷施能更好地促进辣椒植株的生长,且以喷施浓度为0.50%的硼肥效果最显著。

The field experiment was carried out to explore the effects of different concentrations of boron fertilizer on peppers＇ growth and development during the squaring stage and initial flowering stage. The results showed that spraying different concentrations of boron fertilizer could improve pepper＇s growth and increase the fruit-setting rate at both stages, but spraying boron fertilizer at the squaring stage was more helpful to increasing fruit setting rate, and spraying at initial flowering stage was more beneficial for promoting their growth, moreover, 0.5% boron fertilizer got the most remarkable effect.
