Comparision of growth and developmental characters and economic characters of winter rape in different density in Xinjiang
摘要
Abstract
By observing winter rape growth in Xinjiang, a study was conducted on the effect of different density on winter-survival rate, leaf area, leaf area index, net increase of fresh weight, unit area dry matter accumulation of winter rape, and yield, economic characters, oil content of winter rape in Xinjiang. The results presented that density had significant effect on these aspects. Among various kinds of density(30 × 104 plants/hm2, 60 × 104 plants/hm2, 90 × 104 plants/hm2, 120 × 104 plants/hm2 and 150 × 104 plants/hm2), the treatment of 30 × 104 plants/hm2 had relatively larger leaf area, and that of 150 × 104 plants/hm2 had higher leaf area index, while the density of 90 × 104 plants/hm2 had the highest winter-survival rate, net increase of fresh weight, dry matter accumulation per unit area, yield, economic characters and oil content in all the five treatments. Suitable density could increase the winter-survival rate, the growth and developmental characters, yield, economic characters and oil-content of winter rape. The results also indicated that the suitable density of winter rape was 60 × 104 ～ 90 × 104 plants/hm2 in Xinjiang.关键词
