不同覆膜方式对饲草产量的影响

Effects of Different Mulching Methods on Forage Yield

摘要:

为了研究饲用玉米全膜双垄沟播和平膜种植对玉米生长发育、干物质含量及玉米产量的影响，试验选取了安定区广泛种植饲用玉米品种金凯5号、承3359和陕单8806为试验材料，对不同方式种植的玉米在拔节期、大喇叭口期和灌浆期用直尺测定玉米株高、称取测定单株重。结果显示：全膜双垄沟播的玉米株高、干物质含量、单株重均高于平膜种植的玉米。

Abstract:

The purpose of this paper is to study the effects of doublefurrow planting of forage corn with full film and flat film planting on the growth and development, dry matter content and yield of corn. In the experiment, Jinkai 5, Cheng 3359 and Shandan 8806, which are widely planted for forage in Anding District, were selected as test materials. We used a ruler to measure the plant height of corn planted in different ways at the jointing stage, the bell mouth stage and the filling stage, and measured the weight per plant by weighing. The results showed that the plant height, dry matter content and weight per plant of corn planted in double ridges with full film were higher than those planted in flat film.
