Soybean 45 cm double planting cultivation techniques are based on the "Ridge III" cultivation techniques. To increase density, the row spacing is reduced from 65 to 70 cm to 45 cm, and the cultivation method using double ridges on the ridge is adopted. Soybean 45 cm double planting cultivation technology is the best combination of "Ridge III" cultivation technology and narrow-row dense planting technology is an effective way to solve the dense planting of soybean. Our company treats fresh mixed vegetables in a frozen manner. This processing method makes the water in vegetables quickly form regular and fine ice crystals, evenly distributed in the cells, the vegetable tissue will not be destroyed, and the biochemical process inside the vegetables can not be carried out, so bacteria and molds can not develop. Quick-frozen food is very convenient to eat, get indoor without washing, cutting, slightly defrosting. Because most of the frozen vegetable products are cooked, and some may also add salt and other condiments, so cooking with a quick fire, instantly cooked, its taste, color and vitamin content, and fresh food almost the same.

1. Seeds and their treatment. According to the local ecological types and market demand, choose the dwarf or semi-dwarf varieties that suit the local conditions and the stalks do not fall. In addition, the varieties that are earlier than the ripening period of the local varieties are selected to increase production, but the ripening period should not be too early, otherwise the waste accumulated temperature will affect the output. Seeds should be sowed before sowing, sowing seeds or insect seeds and impurities with soybean sorters or artificial granulation. Seed purity, cleanliness is not less than 98%, germination rate is not less than 85%, water content is not higher than 13.5%. Before sowing, it is coated with registered soybean seed coating agent to control underground pests, two leaf nail rot and root rot. Uncoated seeds may be seeded with ammonium molybdate, boron or molybdenum trace fertilizer or zinc fertilizer.
2. Rotation and land preparation. Implement a rational rotation, not re-emphasize, do not greet. Under the circumstance of unavoidable re-enhancement, we insist on the principle of “satisfying and refusing to refrain from re-emphasizingâ€. We can choose to plant soybeans with high levels of organic matter in Pingchuan and Erdao, and we can only weigh the soybeans for one year. For those plots that are developed late and have high organic matter content, although they can be appropriately weighted, they cannot be excessively long. There is no deep or deep foundation ground, where volts, fall or earthworms are deepened, and the depth of tillage is 8-20 centimeters. There are no large earth blocks and dark sandals, per square root. The plowing layer with an inner diameter of more than 5 cm should be less than 5, the depth of plutonium is 12-15 cm, and the depth of deep plowing is 25 cm or more. The crackdown should be done in time to keep the flooding and reach the state of being planted. Deep plowing deep foundations can be used for autumn ploughs, picking rakes, rakes 12 to 15 centimeters deep, and smooth. In spring land preparation, it is necessary to turn over, rake, rake, and press continuously. In arid land, pay attention to the effect of site preparation on water without irrigation.
3. Fertilization. Apply organic manure (above 8% of organic matter content) to 15 tons or more per hectare, combined with one site application of base fertilizer. Fertilizers are used as seed fertilizers, and the fertilizer amount per hectare is calculated as 15% increase over the conventional fertilizer application amount. Apply to the seed 4 to 5 cm, or apply it layer by layer to 7 to 14 cm. Top dressing, when the growth of early soybean is weak, spraying 10 kg of urea plus 1.5 kg of potassium dihydrogen phosphate in 500 kg of water per hectare at the initial flowering stage of soybean, and add trace element fertilizer as required.
4. Chemical regulation. In the case of prosperous growth in the earlier period, if you grow too fast after entering the flowering period, you will grow into an overgrown field, causing lodging, falling flowers, and loss of yield. Therefore, when the plants in the field grow excessively and there is a risk of lodging, you can spray three. Iodobenzoic acid, paclobutrazol, Feng Bao and other agents, to prevent lodging, increase flower protection, increase production.
5. Sow. Ground temperature stability begins at 7~8°C and sowing begins. Central and southern Heilongjiang Province from April 25 to May 10, north and northeast from May 5 to May 15. Mechanically sowing or double row equidistant precision sowing, large row spacing 45 cm, a small row spacing between 10 to 12 cm. Due to the fact that most of the currently used varieties are bred and grown under the normal density of conventional ridges, the density should not be too large when using 45 cm double dense planting. Generally 300,000 to 380,000 seedlings are protected per hectare in Central and South China, and 36 to 460,000 seedlings are maintained per hectare in the northern region. Slurry evenly without broken bar, 20 cm seedless broken bar, no more than 1 broken bar per 5 cm. When planting on a mechanical ridge, it should be aligned with the centre of the ridge roof with a deviation of 3 cm.
6. Field management. When soybeans are arched, deep loosening or plowing before shoveling. For the purpose of weeding and drought-resistance, shoveling can be carried out, and the rate of shoveling seedlings is less than 3%. Pull out the grass later. Disable long-lived herbicides. Spring drought promotes post-emergence grassing. For example, soil moisture can be closed by soil. Closed treatment method: Before sowing soybean seedlings, use 90% acetochlor (1-100 to 1400 ml) and 70% Thiaczine WP (300 to 600 g) per hectare, or 72% Dole oil per hectare. Hectares 1500 to 2700 milliliters, watering 450kg soil spray. After the emergence of soybeans, weeds are controlled at the stage of 2 to 4 leaves to control grass weeds, with 5% galbimose grams of emulsifiable concentrate 900 to 1500 ml per hectare, or 15% spermatozoa to kill 750 to 1000 ml of emulsifiable concentrate, or 10.8% of the high-efficient Gaifu-Qing EC 450 ml, or 12.5 to 1250-1500 ml of Chlamydrup EC, sprayed with 450 kg of water. For control of broad-leaved weeds, use 25% of fomesafen 1000-1500 ml per hectare, or use 24% of Kekelola 450 ml, spray with water. In the autumn, the temperature is stable below 10°C, and the soil moisture is suitable (there is no agglomeration on the ground). After the first leveling, the edge is sprayed with a mechanical traction disk and the depth is 10-15 cm. After applying the drug at the field, he applied it once in a direction at right angles to the first direction. The depth was the same as for the first time. Then he ridged and the autumn application effectively controlled the weeds in the second year. The dosage is 10% to 20% more than in spring. 72% of Dole can be used per hectare, 2500 to 3500 ml plus 48% of clomazone 800 to 1000 ml, or 50% of 120 to 180 g, or 90%. Nice 2200 ~ 2500 ml accelerated 120 to 180 grams.
7. Harvest. The implementation of sub-variety harvest, single storage, single transport. Harvested by hand, 90% of deciduous trees were harvested, harvested mechanically, and the leaves were all washed out and the beans were returned to the ground. The cutting height is based on the height of the ground, usually 5-6 cm. The harvesting loss rate is less than 1%, the threshing loss rate is less than 2%, the crushing rate is less than 5%, the mud face is less than 5%, and the cleanliness rate is greater than 95%. After threshing, mechanical or artificial cleaning is performed, and the quality of the product meets the quality standard of soybean acquisition above grade three.
