黄秋葵化肥及农药减施技术研究

Study on Chemical Fertilizer and Pesticide Reduction Technology of Okra

为了科学减少黄秋葵种植过程中化肥及农药的使用量,提高黄秋葵产量,采用少施多次的方式减施25%、50%、100%化肥;采用生物农药、防虫色板减施化学农药,研究不同施肥、施药方式对黄秋葵产量的影响。结果表明,减施25%化肥、减施20%农药的黄秋葵产量高于对照(常规施肥施药)7.02%。通过少量多次的方式减施25%化肥可有效提高黄秋葵产量,采用防虫色板以及施用生物农药的方式对蚜虫及蓟马的防治效果明显优于对照。

To reduce the amount of chemical fertilizer and pesticide used in okra planting and increase the yield of okra,chemical fertilizer was reduced by 25%,50%and 100%by using less and more times,and chemical pesticide was reduced by using biological pesticide and insect-resistant swatches,so as to study the effect of different fertilization and application methods on the yield of okra.The result showed that the yield of okra with 25%reduction of chemical fertilizer and 20%reduction of pesticide was higher than that of the control(conventional fertilizer application)by 7.02%.The yield of okra could be effectively increased by reducing 25%chemical fertilizer in a small amount and many times.The control effect of using insect-resistant color board and biological pesticide on aphid and thrips was better than that of control.
