| 摘 要： | 为解决干旱区棉田日益严重的"白色污染"问题,从根本上杜绝农田残膜增加,采用桶栽试验研究了5种处理方式:液体地膜1 900 kg/hm~2(LFD1),液体地膜2 200 kg/hm~2(LFD2),液体地膜2 500 kg/hm~2(LFD3),塑膜滴灌(PFD),裸地对照(NFD)对土壤的保温保湿效应及棉花生长响应,探讨了滴灌条件下液体地膜代替塑料地膜的可行性。结果表明:液体地膜覆盖可提高土壤温度,降低土壤水分蒸发量,增强棉株根系吸收与合成能力,加快滴灌棉花前期生长速度,适度抑制后期旺长,增产效果显著。液体地膜覆盖滴灌棉花对土壤环境无不良影响,在干旱区滴灌棉田具有重要研究价值和应用前景。

| Abstract: | In order to solve the problem of cotton fields in arid region and fundamentally eradicate agricultural plastic film increase in agricultural fields, this paper explored the feasibility of replacing plastic mulch with liquid film under drip irrigation condition .To research effects of liquid film mulching on soil temperature , moisture and the growth of cotton under drip irrigation, pot experiment was carried out with five mulching modes: LFD1-1900kg/ hm2, LFD2-2200kg/ hm2, LFD3-2500kg/ hm2 liquid film, PFD-plastic film mulching, NFD-open field with no liquid film used. The experimental results showed that liquid film can increase soil temperature, reduce evaporation of soil moisture, enhance the cotton root absorption and synthetic ability to accelerate the growth rate of the pre-irrigation of cotton, moderate inhibition of the late flourishing, and increase yield significantly. Liquid film mulchingScotton under drip irrigationSwith no adverse effects on the soil environment,Shas the important researchSvalue and application prospectSin cotton field inSarid areas. |
