Method for high-yielding, shaping, cultivating and planting fine staple cottons in cotton region of south Xinjiang based on light characteristic

Abstract

The invention discloses a method for high-yielding, shaping, cultivating and planting fine staple cottons in a cotton region of south Xinjiang based on the light characteristic. The method comprises the following steps of setting control contents and control indexes through managing control points within different growth periods; shaping reasonable growth, development and structure indexes of the cottons according to the control indexes, so that the environmental condition for the growth and the development of the cottons is improved, the intense light and the air admission are realized, the demands of the cottons for light, temperature, water and fertilizer under high density are met, the phenomena of barren stalks and less fruits are reduced, the fruiting rate and the fruit quality are improved, the occurrence of adverse growth, development, structure and environment is avoided, and excellent group and strong individuals are realized. Thus, the light energy is fully utilized. The method for high-yielding and shaping the cottons in the cotton region of south Xinjiang based on the light characteristic provides the planting management basis for cotton production of the cotton region of Xinjiang in the future, and the reasonable plant type structures of the cottons are shaped according to the method, so that the cotton yield of the cotton region can be improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for high-yield shaping cultivation of fine-staple cotton in southern Xinjiang cotton regions based on light characteristics. Background technique [0002] The thermal conditions in the Xinjiang cotton area are insufficient. Except for a few counties in the Yetaya District and Tahaya District in the early and mid-maturing cotton area, the accumulated temperature of ≥10°C can reach 4100-4300°C and 3800-4200°C, which is only equivalent to that of the Yellow River. The Beijing-Tianjin-Tang cotton area in the northern boundary of the basin (accumulated temperature of ≥10°C is 4000-4100°C), but it is far inferior to the cotton area in the Yellow River Basin, and the frost-free period is also shorter. But the light conditions are better than the cotton area in the Yellow River Basin. The research on cotton cultivation technology under ecological conditions in Xinjiang be...
