Embodiment 1

[0022] From October 2014 to October 2015, in the cotton area of ​​the Yellow River Basin in the west of Shandong Province, planting experiments were carried out, and three cotton fields with consistent fertility, soil quality, and lighting were selected, and one piece adopted the short-season cotton wheat of the present invention. Plot 1), one piece adopts the method of direct-seeding short-season cotton after wheat (plot 2), and the other sows conventional one-season spring cotton (plot 3). Among them, the varieties of wheat sown in Plot 1 and Plot 2 are exactly the same as the varieties of short-season cotton.

[0023] Plot 1: Short-season cotton wheat post-direct seeding and early-maturing cultivation method of the present invention

[0024] Wheat was sown around October 15, 2014, and the wheat was managed in the conventional field.

[0025] On June 5-8, 2015, the wheat was harvested after it matured, and the stubble was removed in time after the harvest, and the short-sea...

Embodiment 2

[0035] From October 2015 to October 2016, planting experiments were carried out in the cotton area of ​​the Yellow River Basin in the west of Shandong Province. Three cotton fields with consistent fertility, soil quality and lighting were selected, and one piece adopted the short-season cotton wheat of the present invention. Plot 1), one piece adopts the method of direct-seeding short-season cotton after wheat (plot 2), and the other sows conventional one-season spring cotton (plot 3). Among them, the varieties of wheat sown in Plot 1 and Plot 2 are exactly the same as the varieties of short-season cotton. The specific method of each block is the same as that of Embodiment 1. The production conditions of the three plots are shown in Table 1:

Abstract

The invention provides a method for summer direct seeding after wheat and early maturing culture of short-season cotton. According to the method, stubble seeding is conducted on the short-season cotton after wheat, seedling emergence is quick, budding, flowering and boll opening are early, the pre-frost yield is increased, and the growth period is shorter. By means of the method, the conventional single cotton cropping bottleneck is broken, the problems that conventional direct seeding after wheat of the short-season cotton is late in maturing, low in yield and low in pre-frost yield are solved, the yield is guaranteed, the field growth time of the short-season cotton is shortened as much as possible, early maturing of the short-season cotton is achieved, and cotton-wheat double cropping is truly achieved. The method is particularly suitable for the Yellow River basin.

Description

technical field [0001] The invention relates to an early-maturing cultivation method for short-season cotton wheat, which belongs to the technical field of cotton cultivation. Background technique [0002] As a strategic material of China's important agriculture, cotton is not only an important agricultural raw material for the textile and garment industry and product exports to earn foreign exchange, but also a staple cash crop for farmers to increase their income. In view of international and domestic market demand, China's status as a major cotton-growing country is also unshakable. However, in recent years, with the rapid development of industrialization and urbanization, the growth of my country's population and the reduction of arable land are irreversible. Factors such as the adjustment of planting structure, the contradiction between grain and cotton for land, and the decline in the comparative benefit of cotton planting have led to the reduction of cotton planting ar...
