摘　　要：通过试验比较不同覆膜方式对春小麦的作用效果,结果表明,春小麦播种后覆白膜至三叶期揭膜,由于地温提高,生育期提前,产量和品质均显著提高,但没有节水效果;覆黑膜穴播不揭膜有明显的保水作用,增产效果不大,品质与对照无明显差异。The spring wheat was mulched with white plastic film till three leaves developed,the temperature of ground in-creased,which resulted in an earlier development,the quantity and the quality also increased.However,no water-saving effect was noted.The spring wheat mulched with black plastic film and uncovering had remarkable water-saving effect.However no significant difference was noted for both the quantity and the quality between the tested and the referenced objects under the condition of this test.
