First, timely seeding
The seeds with large, full, lustrous and disease-free plaques are selected as seeds, which are 1-2 days before sowing, and the amount of seeds per acre is about 0.5 kg. Sowing time is from the end of February to the beginning of March, both sowing and direct seeding. The sowing time of the sorghum is selected at the end of February, leaving a 3.3-meter-wide seedbed per acre of field, and making 1000-1200 stalks. When planting, pour the seeds before the seeds, sow 2 seeds per shovel, and cover the fine mud in time. Set up the shed after the herbicide, and open the ditch around the seedbed. The seeding time of live seeding was selected at the beginning of March. After the land preparation in Daejeon, the ridge was 2 meters wide, and it was planted 1-2 days after the application of the base fertilizer in the middle of the shoal. The seeding density per acre was mastered at about 1000 points, and each hole was planted 2 times. Grain, the hole distance is about 66.6 cm.
Second, timely laying and pulling
When the bean sprouts grow into the spinning, the scaffolding starts, and a small bamboo raft is inserted next to each hole, and the two-hole seedlings are formed into a "human" shape, and a bamboo shoot is used as a fixed pile every 20 meters in the middle of the raft. Use the No. 16 lead wire to first fix the fixed pile in the shovel, and then pull the bamboo shoots around the field to prevent the wind from scratching the shelf. Weeding and weeding in time after the scaffolding.
Third, scientific fertilization
If the seedlings are planted, the seedbed is applied to the base fertilizer at the time of sowing. When transplanting, 60 kg of organic compound fertilizer, 15 kg of diammonium phosphate, and 750 kg of gray fertilizer are applied per mu. The first top dressing is carried out after the first harvest. The whole growth period is 2-4 times of topdressing, 50 kg of bean cake per acre, 40 kg of ammonium bicarbonate and 50 kg of compound fertilizer. A top dressing before and after the beginning of the fall (recovery period) must be re-applied; to ensure that the plant has sufficient nutrients, each of the above fertilizers should increase by about 10 kg in quantity.
Fourth, do a good job in the prevention and control of pests and diseases
Before sowing, combine with the water before the seed to disinfect the kneading dough with 50% carbendazim 1000 times solution, sprinkle the cover seed mud, and spray 5 ml of water with 2 kg of water per seedbed to control the weeds. After the seedlings, use 60% anti-mildew 800 times liquid spray to sterilize and prevent diseases. In the future, the same as the live seedlings, in the early stage of the field, if there are mites, 10% per mu, 20 grams of water, 30 kilograms of water spray, and the larvae of the larvae or the larvae of the larvae are treated at the peak of the disease. The selected agents are: 5 % inhibition Taibao 1000 times liquid, 5% card dead grams 1000 times liquid or 10% divided 1500 times liquid, and the drug is used alternately, 4-5 times in the whole growth period, combined with pest control in the field growth period to prevent disease The medicine is mixed with 70% methyl thiophanate 600 times liquid per acre to control downy mildew, etc., and the medicine is used 1-2 times during the whole growth period.
V. Timely harvesting
When the kernels of the tender pods are slightly bulged, they will be harvested and listed. It is not suitable for old or over-harvest harvesting. The harvesting time can be extended until the end of the frost.
Galvanized wire is divided into hot dipped galvanized wire and cold galvanized wire (Electro Galvanized Wire). Galvanized wire has good toughness and flexibility, the maximum amount of zinc can reach 350 g /sqm. With zinc coating thickness, corrosion resistance and other characteristics.
