Transplanting technique of Cotton with plastic Film mulching in Wheat and Oil stubble
The transplanting period of cotton in wheat and rape stubble is late, and the growth period is late. Plastic film mulching can increase temperature and preserve soil moisture, prevent waterlogging and drainage, and it is an effective measure to fight for early development, prevent rigid seedlings and win high yield. After harvesting, the wheat and rape were ploughed, furrowed and ridged, and the ridge surface was covered with plastic film after spraying soil sealing agent. Combined with the application of rotten organic fertilizer 2000kg / mu, compound fertilizer 40kg / mu and boron holding capacity 1kg / mu. The transplanting period of rape stubble can't be fixed in time.

Lu 05h9 pioneered Cotton Marker breeding in China
Recently, a new safflower marked insect-resistant hybrid cotton variety Lu 05H9 selected by the Cotton Center of Shandong Academy of Agricultural Sciences has been examined and approved by the National crop Variety approval Committee. The safflower mark is like putting an anti-counterfeiting label on the transgenic insect-resistant hybrid cotton. This variety has created a precedent of cotton safflower trait marker breeding in China, and it is also the first case in the world. According to researcher Wang Liuming of variety breeding, Lu 05H9 safflower marked insect-resistant cotton transferred the HB safflower character of wild Bick cotton to cultivation through distant hybridization for 12 years.

Feeding ruminant livestock with cotton straw
With the current increase in cattle and sheep stocks year by year, as well as large-scale land development and cultivation, resulting in a sharp decline in the original grazing grassland. Therefore, solving the problem of winter and spring forage for cattle and sheep is the primary problem for the development of animal husbandry in each farming and pastoral farm. In the face of large-scale picked cotton straw, livestock farmers can only scatter cattle and sheep in the ground according to the old method and let them eat freely, resulting in a large amount of waste of resources. In order to make better use of cotton straw and achieve the effect of returning the abdomen to the field, a set of methods for scientifically feeding ruminant livestock with cotton straw were summarized.

Remedial measures of cotton after waterlogging
Cotton has the ability of self-regulation and compensation, and stress-resistant cultivation measures such as drainage, early loosening soil, heavy fertilization, late topping and strong pruning should be taken after the disaster. Scramble for drainage: surprise lower the water level of the outer three ditches, focusing on dredging and deepening the three ditches in the cotton field. In areas with low-lying terrain and high inland water level, it is necessary to use mechanical and electrical drainage to speed up drainage and reduce the underground water level in cotton fields. Early loosening soil: after waterlogging, the soil consolidation and permeability of cotton field is poor, so it is necessary to suddenly loosen the soil 7-8 days after drainage, improve soil permeability and temperature increase, and speed up the growth of cotton seedlings.

Think twice before you expand cotton planting
First, cotton fields are growing steadily and should not be expanded blindly. In recent years, the area of cotton fields in China has changed greatly, and farmers have lost a lot, and the lessons are very profound: first, prices fluctuate greatly under the influence of the international cotton market; second, domestic cotton prices are unstable and it is difficult for farmers to grasp; third, the caliber of cotton production area and yield forecast is very inconsistent, and the reliability of information is poor, so it is difficult for farmers to determine how much cotton to plant. In view of the lessons learned in the past, the cotton field area should only be restored this year, with an increase of 10% and no more than 15% at most. Of course, all localities should respond to the local conditions.

Scientific control of cotton
Chemical control must be flexible according to cotton growth and weather conditions, focusing on prosperous and long cotton fields, soil water shortage, cotton growth should be used less or not. For the cotton fields with prosperous growth trend in full bud and early flowering stage, 1.5 ~ 2.5 grams per mu should be sprayed with 2035 kg water. For the prosperous and long cotton field at full flowering stage, 2 ~ 3.5 grams per mu and 30kg / mu of water should be sprayed on the surface of cotton plants to control the growth of cotton plants and control the daily growth of cotton main stems at 3%.
