Remember, many organic materials such as leaves, grass clippings and chipped branches can be used as a mulch Mulches placed on the soil surface control weeds, reduce evaporation, make soil temperature cooler in summer and warmer in winter, and reduce soil erosion.

请记住，有很多有机材料，如树叶，草，剪报和插话分行，可作为地膜覆盖物放置于土壤表面控制杂草，减少蒸发，使土壤温度较凉夏暖的冬天，减少水土流失。

Plastic mulches directly affect the microclimate around the plant by modifying radiation at the soil surface and decreasing soil water loss.

It was found that all the coloured polyethylene films herein used as plastic mulches increased significantly the soil temperature and conserved soil moisture.

杭州早春，各色地膜覆盖的土壤温度，比对照高1—4℃。地膜覆盖的土壤O_2含量正常，雨后测定，各色地膜覆盖处理的在19.6—19.8％之间，对照为18.8％。各色地膜覆盖的土壤容重都比对照的小，平均为1.08，对照为1.21。

The results showed that spring wheat with plastic film mulches was able to improve the content of chlorophyll and protein of leaves in the earlier growing period and the average increase per day of the content of chlorophyll and protein of the mulched wheat increased by 31.49% and 7.94% than that of unmulched wheat respectively; but it could accelerate the decomposition of chlorophyll and protein in the later period.

结果表明，采用地膜覆盖栽培方法，在春小麦生长前期能明显提高叶片叶绿素和蛋白质的含量（日均增加量分别比露地春小麦高31.49%和7.94%），但后期又会加速其降解速率；MDA含量和细胞质膜相对透性均表现为覆膜处理高于露地处理（日均增加量分别比露地春小麦高71.96%~11.78%和2.42%~9.57%）。
