摘要:

【目的】研究不同滴水冬灌定额对“干播湿出”播种质量、棉花生理、生长特性及产量的影响,确定节水增效的休作期棉田墒情调控策略。【方法】采用在棉田休作期少量灌水调控墒情,春季开播后“干播湿出”的灌水方式,共设计9个处理,冬灌滴灌定额设4个梯度:休作期冬灌滴灌(W1S0~W4S0):600、900、1 200和1 500 m3/hm2;春季播种后采用非“干播湿出”和“干播湿出”2种方案,“干播湿出”定额为225 m3/hm2(W1S1~W4S4),常规冬灌2 250 m3/hm2为对照处理。【结果】滴灌冬灌+“干播湿出”对比仅冬灌处理能够促进苗期棉花生长(株高茎粗显著高于非“干播湿出”及常规冬灌),W1S1~W4S4处理可在棉花营养生长转生殖生长期间在一定程度上可控制株高过度增长,其中处理W3S3及W4S4最为显著;滴灌冬灌+“干播湿出”可提高苗期及蕾期叶面积指数,花铃期后期W1S0~W4S0处理叶面积指数稍高于CK及W1S1~W4S4处理;W1S1~W4S4处理干物质总积累量显著大于W1S0~W4S0处理,可促进生殖器官干物质积累,W3S3、W4S4处理生殖器官干物质积累量比例可占50%以上;花铃期后期叶面积指数与产量呈显著负相关关系,干物质积累总量与产量呈极显著正相关关系,滴灌冬灌+“干播湿出”产量高于仅滴灌冬灌处理及常规冬灌,其中处理W4S4的产量比冬季滴灌的W4S0处理高出18.8%、比CK高出13.5%左右。【结论】休作期滴灌冬灌调控下“干播湿出”灌水模式可再节约灌溉用水24%~36%情况下显著提高棉花产量3.5%~13.5%。

Abstract:

【Objective】Studying the effects of different winter dripping irrigation quotas on the quality of "dry seeding wet output" planting, cotton physiology, growth characteristics, and yield, determining the water-saving and efficient fallow period cotton field moisture regulation strategy. 【Methods】Using a small amount of water regulation during the cotton field fallow period, and the "dry seeding wet output" irrigation method after spring sowing, a total of 9 treatments were set in this experiment, with 4 gradients for winter dripping irrigation quotas: winter dripping irrigation during fallow period (W1S0-W4S0): 600, 900, 1,200 and 1,500 m3/hm2; after spring sowing, two schemes of no "dry seeding wet output" and "dry seeding wet output" were used, with a quota of 225 m3/hm2 for "dry seeding wet output" (W1S1-W4S4), and conventional winter irrigation of 2,250 m3/hm2 as the control treatment. 【Results】Compared with winter dripping irrigation alone, the combination of winter dripping irrigation and "dry seeding wet output" could promote early cotton growth (plant height and stem diameter significantly higher than with no "dry seeding wet output" and conventional winter irrigation), and treatments W1S1-W4S4 could control excessive plant height growth during the nutritional growth to reproductive growth stage to a certain extent, with treatments W3S3 and W4S4 being the most significant; the combination could increase the leaf area index during the seedling and budding stages, and in the late stage of flowering as well, the leaf area index of W1S0-W4S0 treatments was slightly higher than the CK and W1S1-W4S4 treatments; the total dry matter accumulation of W1S1-W4S4 treatments was significantly greater than that of W1S0-W4S0 treatments, which could promote reproductive organ dry matter accumulation, with the proportion of dry matter accumulation in reproductive organs in W3S3 and W4S4 treatments exceeding 50%; the leaf area index in the late stage of flowering was significantly negatively correlated with yield, and the total dry matter accumulation was significantly positively correlated with yield. The yields of combination of winter dripping irrigation and "dry seeding wet output" were higher than winter dripping irrigation alone and conventional winter irrigation, with the yield of treatment W4S4 being approximately 18.8% higher than that of winter dripping W4S0 treatment and about 13.5% higher than the CK.【Conclusion】"Dry seeding wet output" irrigation under fallow period dripping winter irrigation regulation can significantly improve cotton yield by 3.5%-13.5% while saving irrigation water by 24%-36%.
