摘要
为筛选出适宜在陇东旱塬区与饲用小黑麦复种的甜高粱品种,本试验连续2年对8个甜高粱品种的农艺性状和草产量进行研究,以筛选出最佳适宜于复种的甜高粱品种,从而有效解决陇东旱塬区优质饲草总量不足问题。研究表明:饲用小黑麦茬后复种大奖2180、大卡和4264的鲜草产量居前三位,分别为75.69、72.83 t/hm^(2)和69.09 t/hm^(2),复种大奖2180、4264和海牛的干草产量居前三位,分别为21.17、20.02 t/hm^(2)和19.18 t/hm^(2),而且2个年份均能够表现出高产、稳产的优势。因此,大奖2180、海牛和4264可作为陇东旱塬区饲用小黑麦茬后复种的主推品种。
In order to select suitable sweet sorghum varieties for intercropping with rye in the dry plateau area of Longdong,this experiment studied the agronomic traits and grass yield of 8 sweet sorghum varieties for two consecutive years,in order to screen the best sweet sorghum variety suitable for intercropping and effectively solve the problem of insufficient high-quality forage in the arid plateau area of eastern Gansu.The results showed that the fresh grass yield of the top three varieties of wheat after multiple cropping of small black wheat stubble was 75.69,72.83,69.09 t/hm^(2),respectively.The hay yield of the top three varieties of wheat stubble was 21.17,20.02 t/hm^(2),and 19.18 t/hm^(2),respectively,and both years could show the advantages of high and stable yield.Therefore,Grand Prize 2180,manatee,and 4264 could be recommended as the main varieties for replanting small black wheat stubble for feed in the dry plateau area of Longdong.
