摘要： 本文报道了在保护地栽培下改变主枝数目和诱引角度对青椒(魁绿)产量和吸收养分的影响.在增加主枝数和缩小诱引角度的情况下,可使单株总干物重有所增加,并且能促进养分的吸收.减少主枝数目或缩小诱引角度可以调整植株的同化器官和非同化器官的生产构造,从而提高产品的合格率.

Abstract: The effect of different shoot numder and training angle on yield, population structure of plant and nutrient uptake of sweet pepper ’Sakigakemidori’ were investigated in plastic film house. Total dry weight per plant and nutrient uptake increased as increasing shoot number and decreasing the training angle which resulted in the increasing of yield per plant. When the shoot number decreased and the training angle became smaller, the photosyn-thetic organ and nonphotosynthetic organ could be regulated, so the ratio of normal fruit would be increased.
Key words:
Sweet pepper,
Shoot number,
Training angle
