蚕豆全膜双垄沟播技术效应研究

Effect Study of All Membrane Double Ditch Planting Technique of Broad Beans

采用随机区组排列，设3个处理，对蚕豆全膜双垄沟播技术效应进行研究。结果表明，全膜双垄沟播种植能加快蚕豆生育进程，比露地常规种植提旱7d；不同生育时期0～60cm土层含水量，全膜双垄沟播高于半膜、露地种植；随着土壤深度增加，土壤温度逐渐降低。全膜双垄沟播种植在株高、单株分枝数、结荚数、百粒重等方面明显高于半膜和露地种植，而每荚粒数略少于早春半膜和露地种植，早春全膜覆盖种植较早春半膜和露地种植增产分别为600．0和841．5kg／hm^2。增幅分别为13．4％和19．9％。

Using randomized block arrangement, effect of all membrane double ditch planting technique of broad beans were studied by setting three treatment. The results showed that all membrane double ditch planting could accelerate the development process of broad bean, and 7 d earlier than conventional planting; Soil water content in 0-60 cm at different development stages, all membrane double ditch planting was higher than half membrane and open field. With soil depth increasing, soil temperature gradually decreased. Plant height, branch number, podding number per half and hundred grain weight of all membrane double ditch planting were significantly higher than half membrane and open field, and seed number per pod were shghtly less than half membrane and open field. All membrane double ditch planting were higher than 600.0 and 841.5 kg/hm^2 respectively, and the growth rate was13.4% and 19.9% respectively.
