Abstract

In order to ease the the traditional mulching way brought many problems mulching the soil under the coating, the whole field covered \The test Zhangbei in Hebei Agricultural University Experiment Station from 2009 to May 2010 to October test calcareous clay soil is sandy chestnut and meadow chestnut soil. The results showed that: 1. Crops with automatic rupture capacity, its strength is determined by the characteristics of the crop itself, and at the same time by of Futuhoudu and film thickness. Black mulching relative germination rate significantly higher than the white plastic film, and the two mulch on weed inhibition was no significant difference. Soil under plastic mulching, different thickness of plastic film on crop emergence was inhibited significantly enhanced with increasing film thickness; membrane Futuhoudu the most critical factors that affect crop rupture effect. 2. Conventional plastic film mulching has a warming effect, while other soil temperature difference is not obvious. Soil mulching treatment soil temperature amplitude lower than regular film and exposed to. In the day, the whole film, semimembranosus and exposed to more frequently increase of the soil of the film cooling process showed a certain lag effect. Amplitude in terms of the amplitude of the soil of the different treatments are often film gt; open field gt; full membrane gt; semimembranosus; soil temperature differences between the different treatment decreased with soil depth. 3 best water retention effect of the whole film processing, crop water consumption the lowest, followed by a half film and regular film, exposed to the lowest. Places in two different soil test, post-harvest soil water storage volume to the highest of the whole film, exposed to the lowest, while the late growth stage often membrane and semi-membrane soil moisture effects are not significant. Soil Moisture, the whole film in the sandy soil on the effect of management better than the 11.7% increase in test ground water retention effect on beaches. Whole film mulch on soil microbial activation was significantly better than the other covering more significant synergies and partial sandy soil. Testing ground each to cover the processing of soil bulk density than before sowing has declined, in open soil bulk density increased. Which cover the whole film processing bulk density was significantly lower than the other treatments. The overall effect is manifested as full membrane gt; semimembranosus gt; often membrane gt; open field, Saudi gt; bottomland. 6. Often membrane treatment process of crop growth performance early gt; late and the performance of the whole film late gt; preliminary. Role in promoting the overall trend of crop growth pre often film is greater than the other treatments, post the highest of the whole film, open field without promoting effect. Full film processing in the two trials to yield and water use efficiency are significantly higher than other treatments. Beach and sand the whole film than regular film production were increased by 16.57%, 47.30%, and water use efficiency were increased by 36.3% and 63.3%.
