通过对星农2号这个大豆品种进行不同密度对比,探讨其最佳种植密度,能够增加产量,根据大豆品质,增强植株抗病能力,为实践提供理论依据,现将试验结果阐述如下。1材料与方法1.1试验地基本情况试验地设在黑龙江省北安农场,北安市是本地区大豆主要产区之一,耕地多沙壤土,耕层浅,土壤贫瘠,产量一直徘徊在2250~2400kg/hm2,当地大豆多年种植
By comparing the different density of Xingnong No.2 soybean seedling, the optimal planting densities can be explored to increase the yield. Based on the quality of soybean and the ability of disease-resistant plants, a theoretical basis is provided for the practice. The test results are as follows. 1 Materials and methods 1.1 The basic situation of the trial ground Experimental ground located in Bei’an Farm in Heilongjiang Province, Bei’an is one of the main soybean producing areas in the region, arable land sandy loam, shallow tillage, poor soil, production has been hovering at 2250 ~ 2400kg / hm2, local soybean cultivation for many years
