为了研究覆盖材料对新疆哈密灌区玉米生长和营养价值的影响,于2016年3~10月在哈密沁城进行田间试验。试验结果表明,普通膜、降解膜和秸秆覆盖均不同程度的增加了玉米叶面积、干物质积累量和干草产量营养;降解膜覆盖玉米粗蛋白、粗脂肪和粗纤维产量达最大值;与裸露种植相比,普通膜覆盖、降解膜覆盖和秸秆覆盖的玉米单株叶面积分别增加11.52%、10.81%和7.80%,单株干物质积累量分别增加26.84%、23.99%和7.38%,干草产量分别提高22.87%、21.16%和4.10%。从玉米干草产量、营养产量和环保等方面综合考虑,降解膜可作为该区域普通膜的代替覆盖材料。
In order to study the effect of cover material on the growth and nutritional value of maize in Hami irrigation area of Xinjiang, field experiments were conducted in Hsinchu City from March to October in 2016. The results showed that the leaf area, dry matter accumulation and hay yield and nutrition of maize were increased by ordinary film, degradable film and straw mulch. The yield of crude protein, crude fat and crude fiber covered by degradable film reached the maximum. The leaf area per plant increased by 11.52%, 10.81% and 7.80%, and the dry matter accumulation per plant increased by 26.84%, 23.99% and 7.38%, respectively. The hay yield Increased by 22.87%, 21.16% and 4.10% respectively. Considered from the aspects of hay yield, nutrition yield and environmental protection, the degradable film can be used as an alternative covering material for ordinary films in this area.
