【摘要】This paper studied the relationships of covering methods and wheat yield,agronomic characters based on the experiment of different covering methods in Weibei highland. Results were as follows: (1) wheat yield increased significantly when the grounds were covered with common plastic film,straw and common plastic film,straw and water -permeability plastic film. The yield of wheat was highest in DQF treatment,and
reached
6
971
kg/hm2.
Compared
with
no
covering,under different covering matters and terms,the highest increase rate of wheat yield was 92.62 % and the lowest increase rate was 23.16% ; (2) Wheat yield in the treatments that grounds were covered with common plastic film,straw and water-permeability plastic film in the whole process were significantly higher than that in the fallow period; (3) Agronomic characters of wheat were improved greatly after the ground was covered with different materials,but the basic seedling number of wheat decreased in the whole-process mulching treatments.%通过在渭北旱塬的不同覆盖试验,对覆盖方式与小麦产量、农艺性状之间的关系进行了研究.结果表明:(1)地膜、秸秆-地膜、渗水地膜-秸秆覆盖地面后小麦产量显著增加,以地膜全程覆盖处理小麦产量最高,可达6 971 kg/hm2,
