Precautions for corn mulching cultivation

Corn mulch cultivation, with obvious humidification, moisture conservation, fertilizer, full seedling, inhibit weed growth, reduce insect pests, promote corn growth and development, early maturity, the role of yield increase. In order to further improve the level of corn cover cultivation technology, increase the unit area yield, and promote the sustainable growth of food production, should pay attention to the following points in cultivation:

First, the whole ground open moisture

Film cover cultivation of corn, the requirements of flat terrain, deep soil, loose soil, irrigation is convenient, good fertility conditions of the soil plots. After the harvest of the previous crop, timely deep ploughing of the district soil, many harrowing, suppression of moisture, to achieve flat, soil sheep, moisture, on the virtual under the real. 120 cm apart from the moisture, moisture 80 cm wide, moisture 20-25 cm high, moisture in the center of the surface to stay 20 cm wide and 20 cm deep fertilizer ditch, to facilitate the application of fertilizers. Do communicate, soil fine, flat.

Second, sowing and cover film

After water penetration, timely spraying of herbicides and cover film. Herbicide selection "B Xiushui", mu dosage 200-250 grams. Use 900mm/0.005mm or 900mm/0.006mm specification film, cover the film in time to break the film sowing.

Third, scientific formula fertilization

According to years of fertilization experience, combined with soil sample testing, scientific formulations, do to the bottom of the fertilizer a clear. Mu Shi 1000 kg of farmyard manure, calcium 50 kg, 40 kg of urea, 40 kg of Tianteng brand compound fertilizer, zinc sulfate 3 kg.

Fourth, reasonable dense planting

Plant spacing 25cm × 60cm, each moisture sowing two rows, the width between the two rows is 40cm, each hole sowing two seeds, sowing depth control between 3-4cm, to ensure that the number of acres of plants about 4400.

Fifth, lead seedling out of the film, between the seedlings set seedling

7-10 days after sowing, timely introduction of seedlings out of the film, to prevent high temperature within the film burn seedlings. When the seedlings grow 4-5 visible leaves, and time out of the oversized seedlings, weak seedlings and seedlings, retaining the growth of medium consistent strong seedlings, so that the single plant to stay seedlings.

Sixth, plowing management and pest control

When the plant grows to thirteen leaves, raise the ditch small cultivation soil, and according to the growth of seedlings for fertilizer. Selection of coated seed control of underground pests. In the process of corn growth, mainly pay attention to seedling aphids and sticky insects, can choose amitraz, chlorpyrifos and other water spray. Trumpet period pay attention to the control of corn borer, can choose insect sex lure or poisonous soil control. Other pests and diseases are controlled in time depending on the occurrence.
