Ultra-narrow-row cotton planting method

Abstract

The invention discloses an ultra-narrow-row cotton planting method, which is characterized in that in the sowing stage of cotton planting, line spacing of wide rows is controlled to be 70-72cm, line spacing of narrow rows is controlled to be 4-6cm, i.e. an ultra-narrow-row dual-seedling-belt planting mode with line spacing combination of 70-72cm and 4-6cm is adopted, plants between every two narrow rows are in staggered distribution, i.e. triangular distribution, and plant distance of the plants is controlled to be 10-16cm. Compared with the prior art, since the method adopts the ultra narrow row of 4-6cm, but due to the adoption of the triangular distribution between the plants between every two narrow rows, the actual plant distance is enabled to be above 7cm, and the uniform distribution of nutritions of the plants is ensured; and growth difference between adjacent plants is smaller, so that defoliation ripening agent is more uniformly sprayed during harvesting, the defoliating effect is good, the resistance uniformity is good when a mechanical picking head is inserted into cotton plants, and the clear picking rate is generally improved by more than one percentage point during mechanical picking.

Description

technical field [0001] The invention relates to a method for planting cotton, in particular to a method for planting ultra-narrow row cotton. Background technique [0002] my country is an important cotton producing area in the world. The total cotton output in Xinjiang is close to 50% of the national total cotton output. This development trend, according to statistics, in 2012 the area of ​​mechanized cotton harvesting has exceeded 5 million mu. [0003] Most of Xinjiang is a sub-suitable cotton area with low accumulated temperature. The key technical measures for high-yield cultivation are "short, dense, early, and film". The current planting density reaches 14,000-18,000 plants / mu. At present, the narrowest row spacing for cotton pickers is 76cm. If 76cm is planted in a single row, the density cannot meet the requirements, and the output will drop significantly. Therefore, the 66cm+10cm strip planting mode is usually used at present, that is, the wide row spacing is 66cm...

AI Technical Summary

Problems solved by technology

[0007] With the application of cotton mechanical harvesting, new problems have emerged, that is, under the 66cm+10cm strip planting mode, the defoliation effect is not good. The main reason is that the cotton plants in the two narrow rows are arranged irregularly. When the cotton plants grow side by side or close to side by side, the distance between the plants will be too close, and the distance between the plants on the other two sides will be too far, resulting in uneven nutrition during the growth period of the plants. The effect is poor, and the fallen leaves are easy to be scaffolded on the fruit branches, resulting in a high impurity rate in the machine-picked seed cotton, which affects the quality of the processed lint cotton. Difficulty in cotton plants, resulting in low recovery rate during mechanical harvesting
