半直立扁豆密植技术研究

Study on the Close Planting Technology of Semi-erect Lentil

[目的]优化半直立扁豆密植技术。[方法]研究了不同种植密度对扁豆品种帮达早红边、交大绿宝生物性状和产量的影响。[结果]在30 000株/hm^2的密度处理下,帮达早红边产量及综合性状最好;在37 500株/hm2的密度处理下,交大绿宝的产量较高。[结论]在生产实践中,播种密度的安排需与品种的遗传特性相结合,同时要综合考虑当地的气候、土壤、肥水、栽培管理等综合因素。

[Objective] To optimize the close planting technology of semi-erect lentil. [Method]The effects of different planting densities on the biological characters and yields of two lentil cultivars Bangdazaohongbian and Jiaodalubao. [Result]Under the planting density of 30 000 plants/hm2,yield and comphrehensive characters of Bangdazaohongbian were the optimal; under the planting density of 37 500 plants/hm^2,yield of Jiaodalubao was the highest. [Conclusion] During the production practice,arrangement of planting density should combine with the hereditary character,as well as the local climate,soil,fetilizer,cultivation management and so on.
