Cotton "full seedling" six reminder
At the beginning of cotton production, the first and foremost task is to grasp the whole seedlings, and the process of realizing the whole seedlings is also a multi-link process. It is imperceptible to grasp the measures in each link, and it may affect all broadcasts. seedling. In this regard, remind farmers to pay attention to the following six key links:
Leveling up the land uses manpower and material resources to concentrate time on assaulting and leveling land. After the leveling, the cotton fields can not only achieve uniform water conservation, but also improve the progress of ramming. They also have consistent emergence, are easy to nurture strong seedlings, and enhance disease resistance of seedlings. To lay the foundation for drought resistance and drainage.
Scientific achievements in attainment of cotton fields need to be accurate over time, reasonable in water use, and high in quality. The amount of water used for spring fleas is generally 600-900 cubic meters per hectare. The best season for fleas is: clay soils that have not been cultivated in winter. The pods should be completed within 20 days of the sowing date. Sandy soil cotton fields Sputum should be completed about 15 days before planting; saline-alkali plots should be suitable for about half a month before sowing and appropriate increase of about 10% of water consumption. Sputum water consumption is too large or close to the sowing date, it is easy to increase the disease.
Correct use of herbicides The chemical herbicides in the cotton field can be divided into two types: pre-emergence soil treatment agent and post-emergence stem and leaf treatment agent. Only pre-emergence soil treatment agent can be used. After emergence, only the stem and leaf treatment agent can be used. . As far as soil treatment agents are concerned, there is also a long residual period. Herbicides with a long residual effect period should not be used year after year, otherwise they will increase the incidence of cotton plants.
Strict investment in the purchase of cotton varieties to be done when the "five to see": a look at the seed production enterprise qualifications and credibility, second look whether it is a certified species, three to see if the seed channel is legal, four to see if the seed quality meets the national standard requirements, See if there are any purchase tickets.
The proper sowing time should be sown when the local 5 cm soil temperature stably passes 14°C, and the saline and alkali soil cotton fields should be planted when the 5 cm ground temperature stably passes 16°C. Early sowing of low-temperature seedlings of cotton seedlings for a long time, prone to lack of seedlings.
The seedling preparation seedlings are planted with seedlings at the same time as the cotton sowing, so that the seedlings are transplanted, the seedlings can be removed, and the seedlings can be removed.
