行距配置和密度对蒜茬花生生育性状及产量的影响

目的]探明花生-大蒜轮作条件下花生的最佳种植密度和行距配置。方法]采用二因素裂区试验设计,以山花9号为试验材料展开田间试验,研究不同行距配置和密度对蒜茬花生生育性状、干物质积累及产量的影响。结果]行距和密度的互作效应不显著。不同行距配置下,35 cm行距处理的荚果干物质积累和产量均高于其他处理;不同种植密度下,24万穴/hm2密度处理的产量最高。结论]鲁西地区花生-大蒜一年两作种植模式下,采用地膜覆盖,单粒播种,种植密度为24万穴/hm2、行距为35 cm时花生产量最高。

Effects of Spacing Pattern and Planting Density on Growth Characteristics and Yield of Peanut after the Plantation of Garlic

Objective] To study the best spacing form and planting density of peanut after the plantation of garlic.Method] Using two-factor split plot experiment design and taking Shanhua 9 as test material, the influences of different spacing forms and planting densities on growth characteristics, accumulation of dry matter and yield for peanut were studied.Result] The interaction between spacing form and planting den-sity was not significant.The dry matter accumulation and yield were almost the highest under the spacing form of 35 cm.On the other hand, under different planting densities, the yield of 2.4 ×105 caves/hm2 was the highest.Conclusion] To get higher yield, the optimum spacing form and density on Shanhua 9 were 35 cm and 2.4 ×105 caves/hm2 under the planting model of peanut-garlic in one year in west Shandong region.
