摘 要: | 目的】探索蔗地套作马铃薯的适宜种植密度,提高种植效益。【方法】采用随机区组设计,设7个处理,3次重复,研究不同种植密度对蔗地套种马铃薯产量和商品薯率的影响。【结果]马铃薯产量随种植密度的增加而增加,种植密度为6.75万丛/hm^2和6.00万丛/hm^2时产量最高,2个处理间差异不显著,与其他处理差异显著;各处理间商品薯率差异不显著。结论】6.00万丛/hm^2的密度是蔗地套作马铃薯的适宜播种密度。

Effect of Planting Density on Yield and Commodity Potato Rate of Intercropping Potato with Sugarcane |

Abstract: | Objective] The aim was to explore the optimum planting density of intercropping potato with sugarcane and enhance benefit. Method] In the experiment, the randomized block design was used and seven treatments with three repeats were set up to study the effects of different densities on yieht and commodity potato rate. Result] The yield of potato increased with the increasing of planting density. The yields with densities of 67 500 hills per hm^2 and 60 000 hills per hm^2 were the highest. There was no obvious significance between them, but there were significant differences with other treatments. The commodity potato rate with different densities treatments had no significant difference. Conclusion] 60 000 hills per hm^2 was the optimum sowing density for intercropping potato with sugarcane. |
