Timely release of mulching film Cotton's ability to absorb fertilizer and water in the early stage is much stronger than that of live cotton. If we can remove the mulch film and strengthen field management in a timely manner, we can fully take advantage of the mulch cotton; if it is uncovered or unzipped, it is not conducive to Under the roots of the cotton plant, most of the roots are distributed in the upper layer of the soil. The cotton plant has poor support ability and is very easy to fall down. Therefore, it is necessary to peel off the mulching film in time to promote root squatting. Film removal time is most suitable for the early flowering period.
The rapid growth of fertilization material, mulch cotton, is 20-30 days earlier than the live cotton, and all management measures must be advanced accordingly. In particular, it is necessary to quickly apply the flower and bell fertilizer, topdressing 10 kg of urea per mu or applying Sanyuan compound fertilizer. - 15 kg. Potassium fertilizer should be increased by 5-10 kilograms per acre for potassium-deficient cotton fields.
The growth of membrane cotton, which promotes the balanced growth of plants, is prone to madness due to its rapid development. Related measures must be taken to ensure balanced growth. One of the measures to be taken is to use 2-3 g of dildoamine per mu, or 8-12 milliliters of water, to spray 40 kilograms of water after entering the budding period; the second is to pay attention to applying fertilizer in a timely manner. After spraying the conditioner, the leaf color of cotton quickly turns dark green, but this time it is impossible to ignore the problem of latent desorption, and the dressing is still top-dressing. At the same time, we must pay attention to the removal of residual film after removal of the film, so as not to affect the cultivation of the cultivator and post-cultivation management.
