- Abstract:
- At present,small rainfall resources cannot be effectively used in agricultural production.Investigated data showed that there was 100~150 mm and 70% frequency of small rainfall(≤10mm/d) in annual precipitation in semi drought area in Shanxi province of China.According to the results calculated by grain production potentiality of rainfall,the maize yield of 7 500 kg/hm2 would be possible in 246mm rainfall,thus the increase of 3 555 kg/hm2 maize yield in 100mm annual small rainfall would also be possible.In order to exploit small rain resources,the water permeability plastic film has been invented,and it has been used to field covering test in dry land for maize,cotton,wheat,tobacco,etc.The test results in 1997 in Xi County of Shanxi province showed that there was 38.3% increase in maize yield than conventional membrane and 103% increase than no cover.Water permeability plastic film can improve rainfall penetration into soil vertically,modify maximum soil temperature,and ventilate soil,while it also can increase soil temperature and block evaporation.
