摘要:

【目的】研究适合等行距机采棉生长的最优水氮投入。【方法】以新陆中88号为供试材料,总滴灌量3 800 m3/hm2,总施氮量320 kg/hm2,设置3种灌水方式W1、W2、W3,3种施肥方式N1、N2、N3,分析土壤含水率、叶片含水率、棉铃时空分布、农艺性状、产量性状。【结果】W2、N2灌水施肥方式下,土壤含水率相对稳定,更好地给植株提供所需的营养物质。且棉花叶片保持功能的时间较长;W2,N2灌水施肥方式下,棉株成铃数较多,且呈筒状分布,更适宜机械采收;W2,N2灌水施肥方式下,植株获得的单铃重和单株结铃数均达到最高,最高产量为7 070.84 kg/hm2【结论】W2、N2灌水施肥方式为最优水氮投入。

Abstract:

【Objective】 To seek the optimal water and nitrogen input suitable for the growth of cotton harvested by equal row spacing machine. 【Methods】 Under the condition of total drip irrigation volume of 3,800m3/hm2 and total nitrogen application rate of 320 kg/hm2, Xinluzhong 88 was taken as the test material, and 3 irrigation methods W1, W2, W3, and 3 fertilization methods N1, N2, N3 were set to study soil moisture content, leaf moisture content, spatiotemporal distribution of cotton bolls, agronomic traits, and yield traits, etc. 【Results】 Under W2 and N2 irrigation and fertilization methods, the soil moisture content was relatively stable, thus providing the plants with the better required nutrients. In addition, cotton leaves maintain their function for a longer time; under W2, N2 irrigation and fertilization methods, cotton plants produced more bolls and were distributed in a tube shape, which was more suitable for mechanical harvesting; under W2, N2 irrigation and fertilization methods, the both of the boll weight and the number per plant reached the highest at 7,070.84 kg/hm2. 【Conclusion】 W2 and N2 irrigation and fertilization methods are the optimal water and nitrogen input.

Key words: machine-picked cotton; soil moisture content; leaf moisture content; spatiotemporal distribution of cotton bolls; yield
