D膜植棉栽培模式的优势、应用效果及配套栽培技术

Advantages,Application Effects and Supporting Cultivation Techniques of D Film Planting Cotton Cultivation Model

本研究以陆地棉‘新陆中67’为材料,研究D膜栽培模式对棉花生长发育、棉田地温、膜下积温的影响。试验结果表明:D膜植棉‘新陆中67’生育期比C膜提前成熟5~7 d。从苗期生育进程看,D膜栽培棉株果枝数比宽膜多1.9个,具有显著性差异;开花多0.7个,成铃数多0.6个,无显著性差异。株高和果枝数二者表现为显著性差异。D膜与C膜衣分、亩产、收获株数、亩铃数差异表现显著性。D膜的衣分比C膜衣分高1.6%,亩产增产11.37%。膜下温度相比,D膜明显要比C膜高。D膜植棉栽培技术具有较好的增温、保墒、杀虫、压草效果,对棉花产量提高、品质提升具有重要的意义。

Using upland cotton’Xinluzhong67’as the material,the effect of D film cultivation mode on cotton growth,cotton field temperature and accumulated temperature under the film was studied.The test results showed that the growth period of D film planted cotton’Xinluzhong67’was 5~7 days earlier than C film.From the perspective of the growth process of the seedling stage,the number of fruit branches in the D film cultivation cotton plant is 1.9 more than that of the wide film,which has a significant difference;there are 0.7 more flowering and 0.6 more bolls,no significant difference.Both the plant height and the number of fruit branches showed significant differences.The difference between D film and C film coating,yield per acre,number of harvested plants,and boll number per acre showed significant differences.The film content of D film is 1.6%higher than that of C film,and the yield per acre is 11.37%.Co mpared with the temperature under the film,D film is obviously higher than C film.D film planting cotton cultivation technology has good effects of increasing temperature,maintaining moisture,killing insects and suppressing weeds,and is of great significance to the improvement of cotton yield and quality.
