The new pattern of plastic mulch film, it's called “Environmental Degradable Mulch Film” (EDMF), which successfully achieves degradation of appearance from pieces to powders. Therefore the effect of polyethylene powder products of EDMF on physical property and chemical property of soil becomes new hotspot of discussion. This study made use of four kinds of molecular weight to simulate polyethylene powder products of EDMF as soil additive of potted soybean, tested total P, efficient P, organic matter, acid phosphatase of soil in soybean developmental periods. The results showed that the total P content of experimental groups which added polyethylene powder products of EDMF were lower than control group, and the max decrement was 25.5%; efficient P content, organic matter content and acid phosphatase activity had no significant differences between experimental groups and control group in soil, and there were relativity among all of them. Efficient P and acid phosphatase activity, efficient P and organic matter were significant positive correlation (R=0.9982 R=0.9985); organic matter and acid phosphatase were negative correlation (R=-0.9966). The polyethylene powder products of EDMF have no significant effects on efficient P, organic matter and acid phosphatase in soil, whereas there are a little effect on speed total P consumption.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77703520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to realize zero-discharge of wastewater from aquiculture, a field experiment was done that aquiculture water (fertile water for plants) from fish pond was applied to irrigate paddy field. The results showed that: 1) paddy field has an obvious effect on removal of some ingredients contained in irrigation water from fish pond, especially for NO3--N and TP. When aquiculture water stranded in the paddy field for more than 8 hours, the nutrient in it may be assimilated by paddy field 65.23% for TN, 71.97% for TP, 87.28% for NO3--N, 66.84% for NH4+-N and 51.06% for CODMn. 2) when aquiculture water entered to the field and contacted with soil surface and plants, the various forms of nitrogen adsorbed is more than that of the TP and CODMn, in which the NH4+-N and NO3--N adsorbed reach up to 49.92% and 41.78% respectively; when aquiculture water penetrates the soil, the absorption is 45.51% for TP, 35.63% for CODMn and 37.36% for NO3--N. 3) using fertile water from fish pond to irrigate paddy field, an output of rice may get to more than 9000 kg/hm2 under 80% of the conventional fertilizer dosage which means fertilizer-saving 20% in contrast to the local conventional fertilizer use, and get to 7950 kg/hm2 without fertilizer that undoubtedly is the most economical and friendly to environment.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79240420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
