不同栽植密度及施肥量对红蒜产量和品质的影响

Effects of Different Planting Density and Fertilizer Amount on the Yield and Quality of Red Garlic

试验设置栽植密度、种子大小和施肥各3个水平,采用正交设计,探讨栽植密度、种子大小和施肥量对大蒜的影响。结果表明,影响大蒜产量和品质的主要因素是栽植密度。随着栽植密度的增加,产量呈现抛物线增加,增产效果达到极显著水平。施肥处理对大蒜产量和品质也有一定影响。栽植密度与施肥处理之间并不存在互作反应。种子的大小对产量和品质无直接的影响。

The test set of planting density ,seed size and fertilization each into three levels by orthogonal test ,to investigate the effect of planting density,size of seed and fertilizer on garlic. The results showed that ,the main factor affecting the yield and quality of garlic was planting density.With the increasing of planting density ,the yield appeared the parabola increasing ,reached extremely significant level.Fertilization also had certain influence on the yield and quality of garlic. There was no interaction between planting density and fertilization. Seed size had no direct effect on the yield and quality.
