摘要
通过大田试验,研究不同中微量元素对辣椒农艺性状、养分吸收及产量的影响,旨在为辣椒中微量元素叶面肥喷施提供合理依据.设置4个处理,分别为对照(喷施等量清水)、喷施硼肥(糖醇态螯合硼施用量225 g/hm2)、喷施锌肥(糖醇态螯合锌施用量225 g/hm2)、喷施钙肥(糖醇态螯合钙施用量450 g/hm2).结果表明,对照辣椒产量为2 016.7 kg/hm2,喷施硼肥处理辣椒产量为2 400.00 kg/hm2,喷施锌肥处理产量为2 100.00 kg/hm2,喷施钙肥处理产量为2 055.56 kg/hm2,其中,增产效果最差的是钙肥(1.9%),增产效果最好的是硼肥(19.0%).辣椒收获期对照、喷施硼肥、喷施锌肥、喷施钙肥处理的次果率分别为20.16%、11.70%、5.43%、5.42%.喷施锌肥和钙肥可以显著降低辣椒次果率.
Abstract
Through large-scale field experiments,the effects of different micronutrients on the agricultural characteristics,nutrient absorption and yield of chili peppers were studied,aiming to provide a rational basis for the spray application of micronutrients in chili leaf fertilizers.Four treatments are set up:control(spraying an equal amount of water),boron fertilizer(boric acid at 225 g/ha),zinc fertilizer(zinc sulfate at 225 g/ha),and calcium fertilizer(calcium nitrate at 450 g/ha).The results showed that the yield of the control treatment was 2 016.7 kg/ha,while that of the boron fertilizer treatment was 2 400.00 kg/ha.The yields of the zinc and calcium fertilizer treatments were 2 100.00 kg/ha and 2 055.56 kg/ha,respectively.The increase in yield was greatest with boron fertilizer(19.0%)and least with calcium fertilizer(1.9%).The percentages of second-grade fruits for the control,boron,zinc,and calcium treatments were 20.16%,11.70%,5.43%,and 5.42%,respectively.Zinc and calcium fertilizers could significantly reduce the percentage of second-grade fruits.
