近年来,随着有机肥投入的减少,化肥的过量使用,导致土壤肥力降低、养分失调、土壤板结、病虫害加剧,最终影响了西瓜的产量和品质。因此,为验证“卢博士”有机液肥在西瓜上的应用效果,辽宁省建平县农业技术推广中心进行此试验。试验结果:西瓜叶面喷施“卢博士”有机液肥可以减轻病虫害的发生,对提高西瓜品质有积极的促进作用,增产显著,增产率为17.86%。
In recent years, with the decrease of input of organic fertilizer, the excessive use of chemical fertilizers led to the decrease of soil fertility, the imbalance of nutrients, the compaction of soil, the aggravation of pests and diseases, and finally the output and quality of watermelon. Therefore, in order to verify the application effect of “Lu Boshi” organic liquid fertilizer on watermelon, this experiment was conducted by Agricultural Technology Promotion Center of Jianping County of Liaoning Province. Test results: Watermelon foliar spraying “Dr. Lo ” organic liquid fertilizer can reduce the occurrence of pests and diseases, to improve the quality of watermelon has a positive role in promoting a significant yield increase rate of 17.86%.
