不同农用地膜对比试验及其对西瓜的影响

Comparison Test of Different Types of Agricultural Plastic Film and Its Effect on Watermelon

以西瓜为试验材料,对比4种不同类型地膜在田间的综合表现以及对西瓜的影响,以探讨其优缺点。结果表明,透明PE薄膜能够带来农业增产增收,但同时也带来了白色污染;功能性双色薄膜加强了透明PE薄膜的效果,还能阻止杂草生长,减少病虫害发生,能回收处理,减少白色污染,综合性能好;非纺织布能够有效避免坏果的发生,减弱杂草光合作用,抑制杂草生长,减少农药使用,自然降解,节约回收成本,综合性能优越;液态地膜能降低坏瓜率,可集农药、化肥、农膜于一身,提高劳动效率,生物全降解,无白色污染,田间表现好。

Taking watermelon as the test material,the comprehensive performance of four different types of plastic film in the field and its effect on watermelon were studied,in order to understand its advantages and disadvantages.The results showed that the transparent PE films could increase agricultural production,but also bring the white pollution.The function of double color film could strengthen the effect of transparent PE film,prevent weed growth,reduce the plant diseases and insect pests,it could also be recycled to reduce the white pollution,its omprehensive performance was good.Non-woven fabrics could effectively avoid the bad fruit,reduce photosynthesis of weeds and inhibit weed growth,reduce the use of pesticides,degradate naturally,save the cost of recovery,and its comprehensive performance was superior.Liquid film could reduce the bad fruit rate and could be set in pesticide and fertilizer,which improved labor efficiency,biological degradation and without white pollution,it had good performance in the field.
