Abstract:

To study the effects of density on the agronomic traits of mechanical harvest cotton, and to breed the plant variety suitable for mechanical harvest by increasing density. Field experiments with K836 were conducted with three planting densities (3×10 4, 6×10 4 and 9×10 4 plants/hm 2) to study the effects of density and its correlation analysis. The results showed that the plant height, the length of the fruit branch, the length of the first node in the fruit branch, the nodes per fruit branch, the fruit branches per plant and the dry weight per plant decreased with the increase of density. Compared with low density (3×10 4 plants/hm 2), high density (9×10 4 plants/hm 2) had lower single boll weight, higher lint percentage, lower bolls per plant and higher total bolls, but there was no significant effect on yield. The plant height, height of the first fruit branch, the node of the first fruit branch, the length of the fruit branch, the length of the first node of the fruit branch, the nodes per fruit branch, the branch angle, the fruit branches per plant were positively correlated with bolls per plant and dry weight per plant, negatively correlated with single boll weight and yield. Therefore,increasing the density could reduce the plant height, shorten the fruit branch and make the plant more compact. The plant density could be adjusted suitable for mechanical harvesting. The density of 9×10 4 plants/hm 2 in southern Hebei meets the requirements of mechanical harvesting.

Key words: Cotton, Planting density, Plant type, Mechanical harvest traits
