Spring corn mulching is an effective anti-reverse cultivation technique. However, due to farmers' poor mastery of their planting points, some fields have not received the effect of mulching. To promote this technology, the following is introduced. Digital 60m short range laser rangefinder is a laser measurement device which is supposed to replace tape measure, ruler, and other traditional length meauring tool. Laser ruler as its name, it is a electronic ruler which user laser to measure distance. 60M Laser Measure,60M Laser Distance Measure,Laser Distance Measure Oem,60M Digitial Laser Distance Measure Chengdu JRT Meter Technology Co., Ltd , https://www.infrareddistancesensor.com
1. Use fine varieties. According to the climate characteristics and accumulated temperature conditions, select medium-late-maturing varieties with appropriate growth period, blade flushing, strong stress resistance, and large potential for yield increase, such as Xianyu335, Chengyu358, and Nonghua101.
2. Site preparation. The flat terrain is fertile, the soil is deep, drainage and irrigation are convenient, and the soil is suitable for light and medium soil. Plowing at appropriate times, the entire fine level, remove the roots, stones, etc., so that the virtual reality, the topsoil is loose and soft, to warm the security.
3. Cover film. Wide and narrow rows of corn are suitable for selection of 80 cm wide and 0.008 mm thick plastic film. There are two ways to cover the membrane: one is to cover the membrane after seeding, and break the membrane to lay seedlings after emergence. This method is suitable for irrigated land or wetlands with high levels of mechanization. Plotting and seedlings should be timely, otherwise it is easy to burn seedlings. The other is to cover the film in a timely manner and grasp the principle that the cover is not covered at night and the cover is not covered. Seed holes when seeding. After raining, it is easy to make the soil cover on the sowing hole, affect the emergence, should be promptly loosened.
4. Apply base fertilizer. Applying base fertilizer before cover film, increase organic fertilizer, to meet the greatest demand for nutrients in plant growth period.
5. Spray herbicides. Before spraying the film, spray the herbicide.
6. Sow. Usually 7-10 days ahead of the open field, or 5 cm below the membrane temperature stable at 6 °C-8 °C sowing. Deep sowing 4-5 cm.
7. Field management. After planting the land covered with membranes, the hole should be broken in time. Fangmiao should avoid windy days and noon. The land that was sown after the first film was covered and the seedlings were sealed after emergence. When the seedlings were 3-4 leaves, the seedlings were set and weak seedlings were removed. When a missing plant is found, two strains can be left in adjacent holes to make up for the deficiency. After the seedlings are settled, the ridges are cultivated in the cultivator. Completely remove the childbirth in time to avoid consumption of nutrients and moisture. During the trumpet period, it is necessary to prevent corn borer and armyworm. At this time topdressing the remaining 20% ​​of nitrogen fertilizer and watering to prevent premature aging and increase grain weight.
8. Remove the waste film. After the corn is harvested, the waste film should be thoroughly removed to purify the soil and prevent farmland from being contaminated.
