根据2008年在黑龙江省大庆市杜蒙县进行的玉米覆膜试验,对滴灌条件下大垄双行覆膜与不覆膜种植方式下玉米苗期、拔节期进行了不同土层地温的连续测定.结果表明,大垄双行覆膜条件下,苗期地温增加了0.75~1.25℃,拔节期地温增加了1.63~2.35℃.到了生长后期,由于植株的遮挡,覆膜的增温作用逐渐减弱,基本可以忽略覆膜的增温作用.
根據2008年在黑龍江省大慶市杜矇縣進行的玉米覆膜試驗,對滴灌條件下大壟雙行覆膜與不覆膜種植方式下玉米苗期、拔節期進行瞭不同土層地溫的連續測定.結果錶明,大壟雙行覆膜條件下,苗期地溫增加瞭0.75~1.25℃,拔節期地溫增加瞭1.63~2.35℃.到瞭生長後期,由于植株的遮擋,覆膜的增溫作用逐漸減弱,基本可以忽略覆膜的增溫作用.

According to the 2008 corn tectorical membrane experiment which engaged in Dumeng Country, Daqing City, Heilongjiang Province, the temperature of different soil layers had been taken on the continuous determination, in corn seedling stage and jointing stage, under the drip irrigation condition by the planting method of big ridge tectorial membrane or uncovered planters. The results showed that under the condition of tectorial membrane for the big ridge of double lines, the ground temperature increased 0.75~1.25 ℃, and the ground temperature increased 1.63~2.35 ℃ under the jointing stage. At the later period of growth, the warming function had been weakened gradually, which could be neglected basically because of the shelter of the plants.
