Abstract: |
A new film covering and film uncovering method was proposed in this study based on research of double film mulching to explore the effects of different film uncovering methods on growth development, yield and quality of cotton to fundamentally solve the problem of residual film pollution. Five experimental treatments including film side sowing + double film mulching + film uncovering before head water after seedling emergence (T1), film side sowing + double film mulching + top\|film uncovering after seedling emergence (T2), unmulchedsowing (T3), sowing under film + single film mulching + uncovering film after seedling emergence (T4) and sowing under film + double film mulching + top\|film uncovering after seedling emergence (CK) were set under the natural conditions in the field. The differences between treatments were analyzed by measuring the agronomic characters, growth period, boll formation, yield and quality of cotton in different treatments. The results showed that T1 treatment had no significant effect on cotton plant height, T2 and T4 had little effect on cotton plant height, while T3 significantly reduced cotton plant height and inhibited cotton growth. Additionally, T1, T4 and CK treatments significantly reduced the number of weeds, while T2 and T3 treatments had relatively weak control intensity on the number of weeds. Therefore, the film uncovering mode had a certain effect on the length of cotton growth period and the spatial distribution of yield formation. Besides,T3 significantly reduced cotton yield while other treatments had no significant effect on cotton yield. All treatments had no significant effect on cotton fiber quality development. T1 helped control the number of weeds and optimize boll distribution and avoid residual film pollution while it had no effect on reduction of plant height, yield and quality. Therefore, the method in the T1 treatment should be recommended in cotton production. |
