Abstract:

Field experiments were conducted to study the effect of six different planting densities on yield and quality of ‘Xundan 29’. The results showed that, ‘Xundan 29’ have higher yield potential and wider optimal density. It could yield more than 11155.4 kg/hm2 with 5.52×104-8.70×104 plant/hm2. With the increasing of planting density, the content of protein and crude fat of ‘Xundan 29’ decreased and starch content was increased, while the lysine content fluctuated. The plant density of ‘Xundan 29’ was less than 6.75×104 plants/hm2 based on comprehensive consideration. Based on the above, the optimal planting densities was 5.52×104-6.75×104 plant/hm2.
