Recently, Zhao Jianxin, the chief agronomist of Wangcang County, explained the high-yielding technology of early film corn in Huangliang Village, Mumen Town.

When transplanting, care should be taken to pay attention to increase the density of 4-1. The density per mu is 3500-4000 strains, which means that the width and spacing are 20×45 cm (width of about 80 cm). The second is directed cultivation. The first unfolding leaf of maize seedlings should be widened to enhance the ability of corn photosynthesis; thirdly, transplanting the fertilizer with water to make the fat mass close to the soil and cover the film mouth, so that it can live after planting and grow rapidly; The fourth one is to make up for the nest with fertilizers and fertilizers to ensure Miao Qi.

Grasp the basics of three important points, advance the car. According to 2000-3000 kilograms of farmyard manure, 30-50 kilograms of compound manure, and 20-25 manure and livestock manure as base fertilizer per acre, they are applied centrally in the sowing ditch (follicle). Then the whole compartment is advanced, and the width of the car is 60 cm, and it is slightly shaped into a tile. The underground pests of mulch corn are active early. To use the insect pests of the underground pests, the baits should be mixed into the compartment when mixing soil.

Cocoon covered film. When the soil moisture is good after the rain, cover the film in time (if the weed is serious, we should spray the surface with weeds before wetting the film), and the film should be tightened and flattened, without wrinkling, so that the film will adhere to the ground. The membrane is tightly pressed with mud.

Deep nest milk seedlings were transplanted in a directed manner. Maize seedlings are transplanted as soon as they are moved.

One of the first things to strengthen field management is to chase fertilizers in time and fat. When the 6 leaves of maize were unfolded, top-dressing joint fertilizer was applied, and nitrogen fertilizer accounted for 15% of the total nitrogen fertilizer. Heavy panicle fertilizer is applied in 10 leaves and 11 leaves of corn, and 10 days before Daguchi mouth is re-applied and attacked on the basis of 50 kg of carbonic acid per acre to promote differentiation and grain formation in the ear of the female and to inject enough water. To meet the needs of corn growth and fertilizer, so that simultaneous grain and ear growth. At the same time, top-dressing, as appropriate. From flowering to filling stage of corn, the potassium dihydrogen phosphate solution is sprayed on the leaves according to the deferring yellow conditions. For the severely de-fertilized fields, the grain fertilizer should also be added, and 4-5 kg ​​of urea should be used per acre. Deeply applied to prevent premature aging of leaves and increase grain gain.

The second is to control pests and diseases. During the corn flare season, "bio-missiles" are used to prevent corn borer. If the control effect of "biological missiles" is not satisfactory, insecticidal granules are used at the heart leaves, or 90% trichlorfon is used to irrigate the leaves 1500-2000 times. Before and after corn tasseling, mu 50% Jinggangmycin 100 grams -150 grams, 50 kilograms of watered shoots and leaves, to prevent sheath blight and size spot.

The third is to open a ditch. After corn is planted, timely excavation of field ditch will be done so that the ditch in the field will be unblocked, irrigation and drainage will be possible, there will be no accumulation of water in the fields with heavy rain, reduce groundwater, eliminate surface water, and prevent waterlogging. When drought occurs, timely irrigation, prevent drought, and promote the healthy growth of corn.

The fourth is to dwarf the cultivation and prevent the wind from falling down. In order to prevent the corn from being blown down by strong winds, we must implement dwarfing of corn. The specific method is that 3% of early-onset plants in Datian are sprayed when the tassels are first exposed, and 30 mu of corn is used to mix water with 15 to 20 kg of mu, which can be evenly sprayed on the leaves, so as not to spray Spraying, if it rains 4 hours after spraying, it needs to be supplemented, but the dosage should be halved.

The fifth is to peel off the dried seeds. Exposing grains to sunlight in the air enhances metabolic function, increases grain weight, and early maturation.

Finally, corn has more rain in the ripening season, and it must be harvested in time, otherwise it will lead to corn mold rot.
