不同叶面肥喷施对豇豆产量及经济效益的影响

Effects of Different Foliar Fertilizers on Yield and Economic Benefit of Cowpea

以精美翠冠豇豆为材料,探究3种不同叶面肥喷施对早春茬豇豆生长发育、产量和经济效益的影响。试验结果表明,与不喷施叶面肥(CK)相比,喷施生态源系列和黑植系列叶面肥后,豇豆的SPAD值、叶面积指数、荚长、单荚质量、商品性和净收益都显著提高。其中生态源系列叶面肥效果最好,采收期延长17 d,产量提高21.28%,直接带动经济效益1150.00元/667 m^(2)。

The effects of three different foliar fertilizer types on the growth and development,yield and economic benefit of early spring cowpea were studied by using Jingmeicuiguan cowpea as material.The results showed that SPAD value,leaf area index,pod length,single pod weight,commodity and net income of cowpea were significantly improved after spraying Shengtaiyuan series and Heizhi series of foliar fertilizers compared with the treatment without spraying foliar fertilizer(CK).Shengtaiyuan series of foliar fertilizer had the best effect,the harvest period was prolonged by 17 days,the yield was increased by 21.28%,and the economic benefit was directly driven by 1150 yuan/667 m^(2).
