行距配置和灌水量对无地膜滴灌棉田土壤水热及产量的影响
Different row spacing and irrigation water for no film drip irrigation cotton soil hydrothermal and yield
摘要
Abstract
In this experiment,'Zhongmian 619'was used as the test material,and the split zone design was used to study two row spacing configurations of wide and narrow row mode and equal row spacing mode,and three irrigation water treatment conditions were W1(4 200 m3/hm2),W2(5 100 m3/hm2)and W3(6 000 m3/hm2).Changes of soil temperature,moisture and cotton yield in cot-ton fields under drip irrigation without film.The results showed that the soil moisture content increased with the shortening of row spac-ing and the increase of irrigation amount.Compared with P1 mode,the soil moisture content and soil temperature in P2 mode increased by 5.8%-8.3%and 5.8%-10%,respectively.Different row spacing had a significant effect on cotton yield.Under P2 treatment,boll number per plant increased significantly compared with P1 treatment.The yield of W3 treatment was 6.4%and 20.1%higher than that of W1 and W2 treatment(P<0.05).In summary,P2 and W3 planting patterns can improve soil moisture and heat status of cotton field,increase cotton yield,and lay a foundation for the demonstration and promotion of row spacing allocation and irrigation amount of high-yield non-film drip irrigation cotton in Southern Xinjiang.关键词
