The corn mulch film mulching cultivation is suitable for the arable land of the gully land, the second lands and the soil. The terrain is flat, the soil is fertile, the mouth is consistent, and the plots in the north and south are suitable.
2 Soil preparation and fertilization
In the spring when the soil is frozen at a depth of 5-10 cm, the rotary tiller is used to kill the cockroaches. For example, before the cockroaches are hard cockroaches such as corn and sorghum, the smashing of the scorpion "three scorpions" is the standard. When the soil is frozen to a plow, the "three ploughs" are used to synthesize the new sorghum and the scorpion is pressed, and the width is 66 cm. Combined with the preparation of land for each hectare of cultivated land, 150 kg of diammonium phosphate, 37.5 kg of potassium chloride and 150 kg of urea were used as base fertilizer. The whole site requires that the kneading surface be flat, finely shredded and not smashed, which is convenient for laminating.
3 sowing
The suitable sowing date is from April 15th to April 25th. It is suitable to use the varieties with a growth period of 10-15d longer than the local live broadcast varieties, and the effective accumulated temperature is 100-150°C. The variety used in the past years is Sidan19.
Two days before sowing, germination began, and it was cultivated by sitting water filtration. 37.5 kg of diammonium phosphate was applied per hectare for seed fertilizer. According to the ground force, the row spacing is divided into 2866cm, 2666cm and 2466cm. The plots with good ground strength are selected for close planting; the plots with poor soil fertility and low fertilization level are selected for rare planting. Each seed of the buds is 2-3 seeds, and the thickness of the soil is 3-4 cm. (The thickness of the soil covered by the early sowing block should not be less than 3 cm, in order to prevent the cold growth of the corn from freezing.)
4 film
A high-quality mulch film with a thickness of 0.008 mm and an amplitude of 1300 mm is used, and the film is covered by a laminating machine. Each operation covers two turns, and the amount of film per hectare of cultivated land is 75 kg.
In order to prevent the weeds from breaking through the mulch and dissipating heat and moisture, it can be chemically blocked before the film is mulched, that is, evenly sprayed with 38% of atrazine suspension 3000ml and 225-375kg per hectare of arable land. On the frozen side, the film was completed on the same day.
5 field management
5.1 After the emergence of the corn, a strong seedling is manually released every time to prevent the scalding of the seedlings in high temperature weather. And use the soil pressure to compact the mulch of the root of the seedling.
5.2 Due to the high soil temperature of the covered corn mass, some plants have tillers, and the corn is removed manually before the jointing to reduce nutrient consumption.
5.3 In case of special dry years, artificial irrigation shall be carried out 1-3 times depending on the drought to ensure a good harvest.

• Benefits of Oxygen:
Inhalation of oxygen can improve the level of arterial blood oxygen partial pressure and oxygen
saturation of the body, in addition to promote the metabolism of the body, and is also one of the very
important methods for auxiliary treatment of a variety of diseases. Oxygen inhalation can make the
oxygen in the human tissue more abundant, cells will get sufficient oxygen supply after the
metabolism will be more active, normal people will have a refreshed, memory improved, spirit feeling.
Patients with chronic heart and lung diseases, long-term oxygen inhalation can delay the aggravation
of the disease, at the same time, but also can relieve the symptoms of chest tightness, wheezing and
dyspnea of patients. Especially when working under great pressure, they are prone to dizziness,
