不同肥料及施肥方式对小豆农艺性状的影响

以唐山红小豆为材料,研究不同施肥方法对小豆农艺性状和产量的影响。结果表明:施肥对小豆的结荚率、生育期、主茎分枝、单株结荚数及单株生产力的影响较大,对百粒重的影响较低。在始花期和盛花期喷施1%尿素溶液能有效提高小豆的结荚率;底施硼肥和锌肥能促进小豆提前开花和分枝;叶面喷施1%的尿素溶液能有效延长生殖生长期、提高小豆单株结荚数及单株生产力,产量比对照增产39.1%。在较高土壤肥力条件下,小豆最佳的施肥方式是在小豆始花期和盛花期喷施1%尿素溶液。

Effect of Different Fertilizations on the Quantitative Characters and Yield of Adzuki bean

The effect of different fertilizations on the quantitative characters and yield of adzuki bean landraces from Tangshan was studied.The results showed that different fertilizing methods had the big effects on bear pods rate,growth period,number of branches in main stem,pods per plant and productivity per plant,but a little influence on 100-seed weight of adzuki bean.The bear pods rate of adzuki bean was improved by spraying Urea(1%) at initial time of flowering and full-bloom stages.The was imprioved the flowering and productivity per plant was with basing boron fertilizer and zinc fertilizer.With spraying Urea(1%),reproductive was prolonged effectively,as well as pods per plant and productivity per plant,the yield was 39.1% higher than CK.
