The use of mulching in the northern cotton area, seedlings before emergence, and subsequent soil sealing are two essential operations. The seedling releasing operation is mainly carried out manually. Sealing operations can be replaced by machines. At present, the country is prospering the Hejian Park and the breeding bases of Jinghai and Qinghe Farms. It is stepping up the work of sealing the tractor and saving a lot of labor. Why do you have to seal the soil? Because cotton seedlings need high ground temperature and suitable soil moisture, plastic film coverage meets these two requirements. The seedling releasing operation destroys the integrity of the plastic film and reduces the function of warming and protecting the plastic film, especially affecting the surrounding environment of the cotton seedlings. In addition, the temperature in the middle and late of May increases, the wind force increases, the air humidity decreases, and it is easy to cause cotton fields. Severe loss and temperature fall at night, affecting strong seedlings. There are two major benefits to soil sealing operations in terms of warming and protecting the soil: First, it inhibits the growth of weeds around the cotton seedlings; second, it stabilizes the cotton seedlings and does not cause severe damage due to the wind. Entering in June, the temperature and ground temperature have further risen, and the cotton plant has been able to meet the normal fertility requirements. The film has completed its stage mission and it is time to break the membrane and remove the membrane. From an environmental point of view, the use of 100% biodegradable plastic film and other pollution-free high-tech means to replace the current plastic film is an inevitable trend.
