Variety Adaptability of Winter Rye Forage Multiple Cropping Early Maturing Soybean in Horqin Sandy Land
摘要
Abstract
In order to select the suitable early-maturing soybean varieties for multiple cropping after winter rye forage harvest in Horqin sandy land,11 early-maturing soybean varieties such as Neidou 4,Mengdou 5 and Mengdou 11 were selected for multiple cropping after winter rye forage harvest,and their yield and yield-related traits were measured after soybean harvest.The results showed that the plant height of Mengdou 180 was 61.53 cm,the stem diameter of Mengdou 160 and Mengdou 170 were 0.30 cm and 0.31 cm,respectively.The number of pods of Dongnong 36 was 55 per plant,the number of seeds of Mengdou 11 was 137 per plant,the 100-seed weight of Heihe 49 was 21.9 g,and the yield of Mengdou 281 was 2 911.41 kg·ha-1.The correlation analysis showed that the yield of early-maturing soybean was significantly positively correlated with plant height and extremely significantly positively correlated with the number of grains per plant.The comprehensive analysis of membership function showed that the production performance of different early-maturing soybeans was ranked as Mengdou 281(0.89)＞Mengdou 170(0.75)＞Heihe 49(0.74)＞Mengdou 160(0.72)＞Mengdou 343(0.64)＞Neidou 4(0.61)＞Mengdou 11(0.58)＞Dongnong 36(0.57)＞Mengdou 5(0.35)＞Mengdou 180(0.24)＞Mengdou 46(0.22).It is recommended to plant Mengdou 281 after the harvest of winter rye forage in Horqin sandy land.关键词
