Study on the Influence of Planting Density on the Forage Nutritive Value of Spring Soybean Stalk

ZHAI Yun-long et al (College of Plant Science and Technology,Tarim University,Alaer,Xinjiang 843300)  
[Objective]The purpose was to supply theoretical foundation for enhancing the synthetic utilization value of high-yield spring soybean in northern Xinjiang.[Method]The forage nutritive values of spring soybean stalk under 3 planting densities were analyzed.[Result]When the planting density increased from 3.00×105 plants/hm2 to 6.00×105 plants/hm2,the stalk yield increased 26.57%,the contents of crude protein(CP),acid detergent fiber (ADF),neutral detergent fiber(NDF),acid detergent lignin(ADL),acid indiscerptible ashes(AIA),cellulose and hemicellulose reduced 71.28%,3.19%,3.26%,7.54%,9.21%,1.91% and 3.43% resp.,the yield per unit area of CP reduced 63.65%,the yields of ADF,NDF,cellulose,hemicellulose,ADL and AIA increased 22.53%,22.44%,24.15%,22.24%,17.03% and 14.89% resp.[Conclusion]Considering the grain yield and the content and yield of forage nutritive components of high-yield spring soybean in northern Xinjiang comprehensively,the planting density making most use of its potential was 4.50×105 plants/hm2.
