摘要:

【目的】 研究免冬灌、春灌条件下滴水出苗对新疆南疆棉田土壤盐分特征及棉花生长的影响。【方法】 以新陆中67号为材料,设置3个出苗滴水量,分别为150 m3/hm2(W1)、300 m3/hm2(W2)和450 m3/hm2(W3),测定土壤pH及含盐量的动态变化、棉花出苗率、农艺性状、干物质积累特征及产量性状等指标。【结果】 W3、W2和W1处理的表层土壤pH在出苗期分别比播种期降低了0.57、0.43和0.19,含盐量分别降低了44.19%、38.70%和28.72%,但在盛蕾期以后洗盐效果逐渐下降。W2处理的出苗率最高达87.31%,较W3、W1分别增加了11.44和5.78百分点。出苗水量越大,棉株农艺性状指标值越大,W3处理的株高和茎粗较W2、W1分别增加了2.71%、8.31%和5.15%、8.19%,W3处理的平均叶面积指数较W2、W1分别增加了7.57%、11.46%。 W3处理的地上部总干物质积累量较W2、W1分别增加了5.44%、7.75%,茎干物质分配系数表现为W1>W2>W3,叶和生殖器官干物质分配系数表现为W3>W2>W1。出苗水量对单株铃数有一定影响,对铃重和衣分影响不大,W3处理的单株铃数、铃重和衣分最大,但W2处理的收获密度最大,W2处理的产量最高,但与W3处理无显著差异。【结论】 较高的出苗水量能明显降低出苗期土壤表层pH值和含盐量,促进棉株生长和干物质的有效积累,有利于单株产量构成因素的形成,但灌水量过高会影响出苗率,300~450 m3/hm2的出苗滴水量棉花产量较高。

Abstract:

【Objective】 This study aims to study the effects of drip seedling emergence on soil salt characteristics and cotton growth in cotton field in southern Xinjiang under the condition of no irrigation in winter and spring.【Methods】 Xinluzhong 67 was taken as the test material, three seedling emergence water quantities, 150 m3/hm2 (W1), 300 m3/hm2 (W2) and 450 m3/hm2 (W3) respectively, were set to observe the dynamic changes of soil pH and salt content, cotton seedling emergence rate, agronomic characters, dry matter accumulation characteristics and yield characteristics.【Results】 The pH of topsoil treated with W3, W2 and W1 decreased by 0.57, 0.43 and 0.19, respectively at the seedling stage, and the salt content decreased by 44.19%, 38.70% and 28.72%, respectively, but the salt washing effect decreased gradually after the full bud stage.The emergence rate of W2 treatment was 87.31%, which increased by 11.44 and 5.78 percentage points respectively compared with W3 and W1.The greater the amount of seedling emergence water, the greater the index value of cotton agronomic characters.The plant height and stem diameter of W3 treatment increased by 2.71%, 8.31% and 5.15%, 8.18%, respectively compared with W2 and W1.The average leaf area index (LAI) of W3 treatment increased by 7.57% and 11.46%, respectively compared with W2 and W1.The total dry matter accumulation of shoot treated with W3 increased by 5.55% and 7.75%, respectively compared with W2 and W1.The dry matter distribution coefficient of stem was W1 > W2 > W3, and that of leaf and reproductive organ was W3 > W2 > W1.The amount of seedling emergence water had a certain impact on the number of bolls per plant, but had little impact on the boll weight and lint percentage.The number of bolls per plant, boll weight and lint percentage of W3 treatment were the largest, but the harvested density of W2 treatment was the largest, and the final yield of W2 treatment was the highest, but there was no significant difference with W3 treatment.【Conclusion】 Higher seedling emergence water can significantly reduce the pH value and salt content of soil surface during seedling emergence, promote the growth of cotton plant and the effective accumulation of dry matter, which is conducive to the formation of yield components per plant.However, too much irrigation will affect the seedling emergence rate.The yield is higher when the seedling emergence water of drip irrigation is 300~450 m3/hm2.
