mulch plastic film

Thus available , plus straw mulch plastic film method is the growth of micro-environment conducive to a better chili cover model .

由此可得，地膜加秸秆覆盖方式是有利于辣椒生长微环境的较佳覆盖模式。

Effect of Mulch with Plastic Film on Quality of Different Wheat Varieties

覆膜对不同小麦品种的品质影响

This paper deals with the effect of maize stalk mulch and plastic film covering on soil heat variation and soil chemic and physic characteristics , tree growth and fruiting in mountain persimmon orchard .

研究了秸秆覆盖和薄膜覆盖对山地甜柿园土壤水热变化规律、土壤理化性状和树体生长结果的影响。

( Secondly ), in grain ( filling ) period the chlorophyll content of flag leaf and second leaf of the mulch with plastic film were higher than the normal planting , but after booting the difference was very little .

旗叶和倒二叶的叶绿素含量在籽粒形成期前以地膜穴播和膜侧沟播的略高，而籽粒形成期之后三种不同播种方式的几乎无差异；

Plastic film mulch and plastic film combined with straw mulch could increase the leaf relative chlorophyll content , root system vigor and plant height , this was the foundation which these two kinds of mulching practices increase the capsicum yields .

覆盖能增加叶片硝酸还原酶活性，秸秆覆盖与双元覆盖能增加辣椒叶片中的相对叶绿素含量，增强根系活力，增加植株高度，这是这两种覆盖处理下辣椒增产的基础。

The result showed : firstly , the oxidation of root of the mulch with plastic film were higher than normal planting before heading and lower after heading , but the difference was little , and the caduceus trend was not significant .

结果表明，地膜穴播和膜侧沟播小麦的根系活力在抽穗前高于露地小麦，开花期后低于露地小麦，但差异很小，无明显的早衰趋势；

Mulch , especially plastic film combined with straw mulch could significantly increase the capsicum yields , water use efficiency and N-fertilizer use efficiency .

地膜覆盖与双元覆盖处理可改善辣椒品质，覆盖尤其是双元覆盖能显著增加辣椒的产量和经济收入，提高产量水分利用效率、经济水分利用效率以及氮肥利用率。

The mulch is a white plastic film that is impermeable and airtight .

地膜是一种白色塑料薄膜，不透水且不透气。

Based on nature evaporation experimentation with artificial controlled precipitation , the evaporation and availability of soil water to plant under 50 % cover rate conditions with four types of mulch materials , including plastic film , water permeable plastic film , hay and sponge plastic sheet , were studied .

采用旱棚人工控水，蒸发桶整体称重法，对4种地面覆盖材料、50%覆盖度条件下，土壤水分蒸发与移动性能进行了研究。

Field Temperature Characters with and Without Plastic Mulch STUDY ON ROW MULCH PLASTIC FILM COLLECTOR

覆膜与不覆膜条件下地温场特性研究

According to the water and calorific condition on Loess Plateau and the research results obtained , different mulch types such as straw mulch , plastic film mulch , biological mulch , etc.

依据黄土高原区的水热条件，结合已有研究结果，简述了黄土高原地区农田不同覆盖类型，诸如秸秆覆盖、聚氯乙烯薄膜覆盖、生物覆盖等。

Dealt with accordingly and uncovered , straw mulch and the mulch cover can reduce the total runoff deep , straw mulch is better than plastic film mulching .

与不覆盖相应处理相比，秸秆覆盖和地膜覆盖均能降低径流总深和侵蚀泥沙量，而秸秆覆盖效果优于地膜覆盖。
