I. Fertilizing the land and doing it Second, sowing The growth temperature of green radish is in the range of 10-25 ° C. The growth is stopped below 6 ° C. The growth is more than 30 ° C. Sowing date: It should be planted in a timely period, not too early or too late. If the planting is too late, the temperature will decrease in the later period, which is not conducive to the expansion of the fleshy root. In our northern region, the sowing period is around August 1-5. Seeding rate: about 8,000 square meters per 667 square meters, more than strips, line spacing 33 × 20-22 cm, 9000-10000 plants per 667 square meters is appropriate. The sowing depth is 1.5 cm. Cover the soil about 2 cm after sowing, and suppress it at the right time. When the sensation is good, the haystack can be dragged once on the second day; when the sputum is bad, the soil is pressed and the water is sprayed in time. Third, field management After the seedlings are out, the first seedlings, the spacing of the seedlings is 3-4 cm; the second seedlings of 3-4 true leaves, the spacing of the seedlings is 10-12 cm; the 5th time of the 5-6 true leaves, the seedlings, Seedling spacing 20-22 cm. Remove the weak seedlings and diseased seedlings during the seedlings, and pay attention to timely replenishing the seedlings. Watering masters the principle of moist soil and pre-control. Generally, the germination period is not watered, and the effective water content of the soil is maintained at about 80%; the small water is poured in the seedling stage to keep the soil moist; the fleshy roots are in the early stage of grasping the principle of “not drying or pouring, the land is white and pouringâ€, but pouring The water should not be too much; the growth of the fleshy roots ensures that the watering is even and sufficient. In this period, attention should be paid to preventing flooding and drought prevention. Generally, water is poured once every 5-6 days, preferably in the evening. Stop watering 7-10 days before harvesting. Fertilization principle: It is necessary to master the application of organic fertilizer, control the amount of nitrogen fertilizer, and increase the application of potassium fertilizer. When planting, every 667 square meters with the application of ternary compound fertilizer (15-15-15) 5-8 kg. In the early stage of fleshy root growth, 20 kg of potassium sulfate or 100 kg of ash was applied. Cultivating and weeding: master the principle of first deep and shallow, first and then far, and stop cultivating after sealing. Be careful not to hurt the roots of the seedlings. Herbicides are weeded and sprayed evenly on the ground before emergence after sowing. Commonly used medicinal agents: 50-70 ml of acetochlor per 667 square meters, 120 ml of butachlor, or 80-100 ml of 72% dul, or 200 ml of 25% alginate, or 50% big benefit 100 -150 ml, or 25% herbicide ether 500 ml, can receive better herbicidal effect. Pest control: As far as possible, we should choose the oysters that have not been planted with radish, so that we can receive the pollution-free cultivation effect without disease. When a disease occurs, it should be strictly used in accordance with the following medication methods, and it is strictly forbidden to exceed the standard. The virus prevention and treatment is sprayed with 20% virus A wettable powder or 1.5% phytopathic emulsion 1000 times liquid, and the whitefly is controlled by imidacloprid insecticide in time. Saw blade is a general term for thin circular cutting tools used to cut solid materials.Saw blade can be divided into: Diamond Saw Blade for stone cutting;HSS saw blades for cutting metal materials (not inlaid with carbide head);TCT saw balde used for cutting solid wood, furniture, wood-based panel, aluminum alloy, aluminum profile, radiator, plastic, plastic steel and so on Flap Disc,Tct Saw Blade,Bevel Brushes,Segment Blade Behappy Crafts (suzhou)Co.,Ltd , https://www.craftsbehappy.com
Choose plots with deep, fertile soil and good irrigation and drainage conditions. After planting the plot, the stalks of 4000-5000 kilograms of fully-fertilized high-quality ring fertilizer, 75-100 kilograms of decomposed cake fertilizer or 50 kilograms of ternary compound fertilizer are used as base fertilizers for 667 square meters, and the depth is 30 centimeters. After exposure to the sun, the sputum is used for sputum cultivation. It is about 20 meters long, 1.2-1.5 meters wide, 20- 30 cm wide and 15 cm high.
