含除草剂非织造布的示范推广试验研究

含除草通的非织布用取农用薄膜的作物地面覆盖材料，经１年来的示范推广试验表明，其防草效果达到９０％以上，与农用黑膜接近，优于农用白膜，其对作物株高，叶片生长无影响，在农田管理得当（生长期保证灌水）条件下，有一定增产效果；对试验作物草莓，茄子，番茄，辣椒的可食部分的除草通残留量测定，未检出，农用薄膜在土壤中残留的模拟试验表明，作物根系能穿过非织造布生长，涂用的除草通在土壤中了最终浓度是非织造布上的喷涂

Experimental Study on Demonstrative Popularization of Herbicide Non-wovens

Herbicide non-woven is used for taking the place of mulching material, during one and half year demonstrative popularization test, its effective weed control was up to 90%, approaching black plastic film and better than white plastic film, and did not effect on the trunk or leaf of the crop, under appropriate farmland management conditions, it may increase crop production. To experimental crops, such as strawberry, eggplant and pepper etc. the herbicide residue in edible portion did not detect. Simulating experiment on soil residue of agricultural film showed that the root system of the crop could penetrate non-woven, and the ultimate concentration of smeared herbicide was part per 60 thousand of the spraying herbicide non-woven cocentration (0.2mg/kg), and could not cause pollution.
