| 摘 要： | 在豫东棉区采用甘薯、芝麻、花生、糯玉米与棉花间作和棉花单作,分析不同间作模式的产量和经济效益。结果表明,棉花/糯玉米和棉花/芝麻间作对棉花生长的影响较早(6月9日、7月9日),至盛花期(8月8日)棉花株高分别比棉花单作增加17.03 cm和13.94 cm(P0.01),伏桃较棉花单作分别减少6.60个/株和8.83个/株(P0.01);与棉花单作相比,棉花/花生间作的年总产值增加14 909.5元/hm~2,纯收入增加11 224.4元/hm~2,光能利用率提高25.01%,棉花/芝麻间作的年总产值增加14 352.8元/hm~2,纯收入增加11 936.6元/hm~2,光能利用率提高7.02%,具有明显的间作优势。

Research on Yield and Economic Benefit of Different Intercropping Patterns in Cotton Field of Yudong Plain |
| |
| Abstract: | A field experiment was conducted in Yudong Plain to investigate the effects of intercropping patterns on cottonyield and economic benefit.Cropping patterns included cotton/sweet potato,cotton/sesame,cotton/peanut,cotton/waxy cornintercropping and cotton monoculture.The results showed that effect of cotton/waxy corn and cotton/sesame intercropping on the growth of cotton was earlier(June 9,July 9),during full-blooming stage(August 8),cotton plant height under intercropping systems of cotton/waxy corn and cotton/sesame was higher than cotton monoculture by 17.03 cm and 13.94cm (P＜0.01),the summer boll number per plant was lower by 6.60 bolls and 8.83 bolls (P＜0.01).Compared with monoculture cotton,the cotton/peanut intercropping could increase annual total output value by 14 909.5 yuan/hm2,net income increased by 11 224.4 yuan/hm2,and light use efficiency by 25.01％,the cotton/sesame intercropping could increase annual total output value by 14 352.8 yuan/hm2,net income increased by 11 936.6 yuan/hm2,and light use efficiency by 7.02％,respectively,indicating a significant yield advantage. |
