In the cotton planting of mulch film, due to improper film uncovering time, the fertilizer is not timely or insufficient to cause the cotton plant to fall and premature aging. Therefore, the following measures should be taken in a timely manner:
The topping of cotton has obvious effect of increasing yield and income, and has certain nutritional guiding effect on the development of developed roots. However, the top of the cotton plant is a part of the cotton bollworm and other pests. The artificial topping will give the top of the heart to attract the eggs of the cotton bollworm. Adults and nymphs suck the cotton tip, young leaves, young buds, young bells, etc., which can cause cotton. The top buds of the seedlings turn black and become black, forming long cotton or branches and leaves, and the cotton leaves are broken, and the young buds and bells fall off. A scientific research achievement that can replace the artificial topping technology of crops----"Foliage Fertilizer", which was successfully developed by Shaanxi Weinan High-tech Zone Foliage Fertilizer Technology Co., Ltd., after many trials and demonstrations, will be launched in 2010. National market.
Foliar fertilizer topping technology successfully replaced the traditional technology of artificial topping buds, reduced fatigue, banned the use of hormone pesticides, and avoided the effects of phytotoxicity; it is the most scientific, labor-saving and most economical plant nutrition transformation. Technology, and can promote cotton bead damage (wounds, insect bites and other wounds) to quickly heal, prevent cotton bollworm eggs and virus damage, inhibit axillary buds, side-heart growth; simple to use, green and environmentally friendly.
The initial flowering period is the most suitable time for uncovering the film, preventing the cotton plant from falling down easily after the film is uncovered or not peeled off. The cotton plant is evenly sprayed with a new high-fat film to enhance its support ability and reduce the lodging hazard. Because the film cotton grows fast, in order to control its sluggishness, each time the medicine is sprayed or the foliar fertilizer is sprayed, adding the appropriate amount of “cotton Zhuangtinging†capsule can make the cotton nutrient delivery catheter thicker, increase the nutrient transport volume, and promote cotton. The growth function can transform the reproductive function, increase the expansion of the cotton bud, control the stalks, increase the resistance, protect the buds and keep the peaches, speed up the cotton circulation, and improve the fiber quality. At the same time, it can increase the efficiency of various pesticides and foliar fertilizer by 30%, and the amount of fertilizer is reduced by half. It is suitable for use in cotton fields under different soil conditions and different climatic conditions throughout the country. Pay attention to the top dressing after spraying the regulator, remove the residual film after uncovering the film, so as not to affect the management of cultivating and post-cultivation.
