摘要
为筛选出适宜核桃幼园套种条件下的高产稳产且适应性好的大豆品种,以期提高商洛地区大豆的播种面积、产量和经济效益,采用显著性差异、变异系数、回归系数、高稳系数、聚类分析等方法综合评价了 6 个大豆品种的高产稳产性和适应性.结果显示:陕垦豆 4 号、陕豆 125、齐黄 34 共 3 个品种为核桃幼园套种条件下高产稳产、适应性好的品种,且类群I(陕垦豆 4 号、陕豆 125、齐黄 34)平均株高为66.10 cm,平均单株荚数为 81.53 个,平均单株粒数为 152.61 粒,平均百粒质量为 28.45 g,平均生育期为 133.67 d的大豆品种及其类似品种在商洛核桃幼园套种条件下具有一定的优势.因此,陕垦豆 4 号、陕豆 125、齐黄 34,以及与其类似的品种可在商洛同类生态区核桃幼园中作为高产稳产大豆品种适当加以应用.本研究为商洛核桃幼园套种条件下大豆品种选择提供了理论参考.
Abstract
To screen out soybean varieties with high and stable yields and good adaptability under suitable intercropping conditions in walnut orchards,in order to improve the sowing area,yield,and economic benefits of soybeans in the Shangluo area.This study com-prehensively evaluated the high and stable yield and adaptability of six soybean varieties using methods such as significant differences,coefficient of variation,regression coefficient,high stability coefficient,and cluster analysis.The results showed that Shaan kendou 4,Shaandou 125,and Qihuang 34 were three varieties with high and stable yields and good adaptability under intercropping conditions in walnut orchards.Group I(Shaankendou 4,Shaandou 125,and Qihuang 34)had average plant height of 66.10 cm,average pods per plant of 81.53,average grains per plant of 152.61,and average per hundred seeds weight of 28.45 g,Soybean varieties and simi-lar varieties with average growth period of 133.67 days had certain advantages under intercropping conditions in the Shangluo walnut nursery.Therefore,Shaankendou 4,Shaandou 125,Qihuang 34,and similar varieties can be appropriately applied as high-yield and stable soybean varieties in walnut orchards in similar ecological areas of Shangluo.This study provides a theoretical reference for the selection of soybean varieties under intercropping conditions in the Shangluo walnut nursery.
