Light Cotton Seedling Raising And Pplanting Technology In Jiangsu Has Become The Mainstream Technology In Cotton Production.

< p > labor intensity and low efficiency are one of the main reasons that affect the stable development of cotton production.

In recent years, Jiangsu has vigorously demonstrated and popularized cotton seedling raising and pplanting technology, which has simplified cotton seedling pplanting process, not only saving land, saving film, saving seeds and saving labor, but also greatly improving production efficiency.

At present, the technology of cotton seedling raising and pplanting in Jiangsu has been popularized for 80 thousand mu and has become the mainstream technology in cotton production.

< p > according to the relevant person in charge of planting station of the Jiangsu Provincial Agriculture Commission, under the support of the Ministry of agriculture's cotton seedling raising and pplanting technology demonstration project and the provincial three new agricultural project, the cotton seedling raising techniques of Jiangsu demonstration and extension are mainly three technologies: substrate seedling raising, water floating seedling raising and self-developed base seedling raising.

Through experiments and planting contrast, substrate plug seedling has become the main pushing technology, and the proportion of demonstration area is over 80%.

Matrix plug seedling is to replace the nutrition bowl and nutritive soil by using the traditional bowl planting system in the field instead of the nutrition bowl and the substrate. The farmers can complete the substrate installation and sowing at home, reducing the labor intensity and increasing the planting benefit.

According to statistics, in 2012, the average yield per mu of Jiangsu cotton plain seedlings was 105.2 kilograms, which was 16.98% higher than that of the traditional seedling raising, and the comprehensive efficiency of Mu was about 657 yuan.

"P > variety and chaos are common" stubborn diseases "faced by cotton production.

In the process of popularizing cotton seedling and pplanting technology, Jiangsu has rebuilt the professional service organization of seedling raising to carry out the service of generation and generation, and requested the service organization to select cotton varieties with strong growth potential and high stress resistance to breed and popularize cotton varieties that meet the national quality standards and requirements.

It is understood that Sheyang and Dafeng two counties and cities more than 40 thousand mu of cotton light seedling pplanting area only 4 varieties, and seedling survival rate is higher than the traditional nutrition bowl seedlings two percentage points.

The family farm of WANYING Town, Dafeng City, used 450 thousand seedlings in the greenhouse this year to supply more than 300 mu of cotton fields in the surrounding area, and the original cotton and silver professional cooperative in Sheyang county has been the main force in the county's simple seedling breeding through the cooperation with seed industry companies, and has undertaken about 90% of the seedling raising task in the project area.

< p > it is reported that in mechanized pplanting, Jiangsu has set up 10 demonstration plants to carry out mechanized pplanting of cotton seedlings this year, with a total area of about 2000 mu.

The scale of mechanized pplanting in Sheyang County reached 300 mu, and the pplanting efficiency reached 5 mu per hour, 10 times of the artificial pplanting nutrition bowl, and the survival rate of pplanting was 95%.

At present, Jiangsu is organizing an expert group to further study the mechanized pplanting technology and mechanical harvesting experiment, and accelerate the mechanization process of cotton production.
