摘要
为研究不同栽种规格的木薯间作糯玉米模式和发掘高产高效间作模式,对木薯净作,糯玉米净作和8种木薯间作糯玉米模式进行了鲜薯产量和经济效益的研究。结果表明:木薯间作糯玉米模式是可行的,体现出明显的间作优势。发现不同间作模式的经济效益不同,其中处理9(大行距100 cm,小行距70 cm)的鲜薯产量(51 274.36 kg/hm^2)最高,处理4(行距100 cm)的经济效益(52 794.15元/hm^2)最高,处理9的经济效益(46556.97元/hm^2)排第3位。综合评价认为,处理9的木薯间作糯玉米模式最合理。试验结果为进一步推广高产高效木薯间作糯玉米模式提供了有力依据。
Cassava was intercropped with waxy corn in 8 patterns with monoculture of cassava and waxy corn as controls to compare the yield and economic benefit of the intercropping patterns. The results showed that cassava intercropping with waxy corn was feasible and had obvious advantages. Different intercropping patterns produced various economic returns, of which treatment 9 （Paired rows spacing： 100 cm and 70 cm） produced the highest fresh tuber yield （51 274.36 kg/hm^2） and treatment 4 （row spacing 100 cm） had the highest economic retums （52 794.15 yuan/hm^2）. The treatment 9 produced the third economic returns （46 556.97 yuan/hm^2） in all the treatments. Comprehensive evaluation showed that the treatment 9 with paired rows of 100 cm and 70 cm was the most reasonable pattern of intercropping of cassava with waxy corn. This experiment provided reference for cassava ＋ waxy corn intercropping with high yield and economic benefit.
