Problems solved by technology

[0003] In order to solve a series of problems caused by wind disaster after sowing or failure to sow on schedule in sub-early cotton areas in southern Xinjiang, a high-yield and high-efficiency method for planting early-maturing cotton varieties in sub-early cotton areas in southern Xinjiang was proposed

Embodiment Construction

[0022] The experiment in the present invention was arranged in the 1st regiment of Nongyi Division of Xinjiang Production and Construction Corps from 2009 to 2010. The test materials were early-maturing varieties "Xinluzao 33" and "Xinluzao 45" in northern Xinjiang, and the control was Nongyi The division 1 group popularized the "Zhongmiansuo No. 41" early and mid-maturing variety on a large scale. In 2009, the plot experiment was carried out, and the plot area of ​​the test and control varieties were both 1 mu; The planting areas of "Luzao No. 45" and "Zhongmiansuo No. 41" are 150, 70, and 100 mu, respectively.

[0023] A high-yield cultivation method for planting early-maturing cotton varieties in sub-early-maturing cotton areas, comprising the following steps:

[0024] The soil is selected as the paddy field before the test site, and the plot with general soil fertility is selected. The soil texture is loam and light loam, the organic matter content is ≥ 0.8%, the alkaline ...

Abstract

The invention provides a high-yield cultivation method for planting a precocious upland cotton variety in a precocious cotton area, in order to solve the problem of greatly reduced output caused by the windstorm disaster in a southern Xinjiang precocious cotton area or the precocious and middle-mature varieties after late sowing is performed. Different from the traditional cultivation method for the precocious and middle-mature varieties, the high-yield cultivation method is characterized in that: 1) the sowing time is delayed for 10-25 days; 2) the sowing density is increased by 1000 strainsper mu; 3) topping is performed before and after July 20, the topping time is delayed for 8-12 days, the number of leaved fruit spurs is increased to 1-2 and the stem length is increased to 5-10cm; 4) after topping, the chemical regulating times is changed into two from one, the elongation of the top fruit spurs is boosted, the number of the coped buds and the bud yield are increased; and 5) the pre-frost yield rate is increased from 95% to above 98%. According to the high-yield cultivation method provided by the invention, the output of cotton is not reduced by the after-culture or late-culture, the output of pre-frost lint is slightly increased, the level of the lint is increased and the income of a cotton planter is increased.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural cultivation and relates to a high-yield cultivation method for cotton. Background technique: [0002] Xinjiang has a vast territory and diverse ecological types. From north to south, the Xinjiang cotton area is divided into four ecological types of cotton areas: extra early maturing, early maturing, second early maturing (early and middle maturing), and medium maturing cotton areas. Among them, the second early maturing cotton area has the largest area and is mainly distributed in the south In the Xinjiang Basin, early and mid-maturing cotton varieties are mainly planted in this area, and the growth period is distributed between 135 and 140 days. Compared with early and mid-maturing cotton varieties, early-maturing varieties have the characteristics of shorter growth period and lower yield. Therefore, early-maturing varieties are generally not planted in sub-early-maturing cotton areas. How...
