Selected varieties: early maturing varieties such as Taiwan 48, Zaoguan, Jinfeng No. 2, Liaoxian, 95-1, etc., can be covered with plastic film in small and medium sheds from early to mid-February to early March, or use plastic film to warm the seedlings and transfer Cultivation method. 1. One week before planting, apply 500 kilograms of decomposed human and livestock manure per mu or 100 kilograms of ternary compound fertilizer, spray with 48% trifluralin to weed and cover the arch shed. 2. Moderately dense planting. When the ground temperature at a depth of 5 cm in the shed reaches above 12°C, choose cold tail and warm head for clear seeding. Generally, the border is 20 cm high and 1.2 meters wide. Each border is planted in 3 rows and the hole spacing is about 20-25 cm. Each hole is sown with 2-3 grains and 2 plants are planted. The sowing amount is 10-15 kg per mu. After sowing, the entire border surface is covered with a layer of mulch. There are more than 13,000 seedlings per mu. 3. Diligent management and skillful topdressing. After the top soil of the cotyledon of the seedlings was removed, the mulch was removed and the soil was loosened by cultivating once. Strengthen cold-proof and warm-keeping measures when encountering low temperature and cold wave. Continuous rainy weather cleared the gullies around the shed in time to prevent waterlogging damage. When the temperature in the shed reaches above 25℃, ventilate in time. During the flowering period, keep the daily temperature in the shed at 23-29°C, the night temperature at 17-23°C, and the relative humidity around 75%. Watering should be done frequently to keep the soil moist during the flowering and podding period. Topdressing 25-35 kg of quick-acting nitrogen fertilizer per acre at the initial flowering stage, and spraying potassium dihydrogen phosphate solution + 1% urea solution 2-3 times on the foliar surface at the pod-blowing stage can effectively increase the number of pods and promote grain swelling. 4. Timely control pests and diseases. In the seedling stage, spray 2-3 times with 50% aphid mist wettable powder or 2.5% deltamethrin EC 2000-3000 times. The pod borer can be controlled with 800 times crystal trichlorfon solution for 2-3 times at the flowering and pod stage. 5. Harvest in proper time. The shed can be harvested and marketed about 70 days after planting. If the seeds are planted from the end of February to the beginning of March, they can be harvested in mid-May. Two, the key points of cultivation techniques for early maturity mulching Selected varieties: Early maturing varieties such as Taiwan 48, Zaoguan, Jinfeng No. 2, Liaoxian, 95-1, etc., are sown in mid-to-late March, covered with mulch or seedling transplanting. The methods of fertilization and soil preparation and planting are the same as early maturity mulching cultivation. The open area is well ventilated and the seeding density can be appropriately increased. The plant spacing is 20-25 cm and the row spacing is 30-40 cm. Each hole is sown with 2-3 seeds and planted with 2 plants. Due to the high temperature and drought during the flowering and pod setting period, special irrigation and drainage work should be done in cultivation. Timely topdressing reduces flower and pod falling. Secondly, it can be cultivated from mid-March to mid-June in the outskirts of grain production areas. Edamame cultivation should not be continuous cropping. The same plot should be separated by 1-2 years. The soil should be near-neutral soil rich in organic matter and with considerable water retention capacity. Acidic soil should be neutralized by lime, ordinary soil per acre 5-7.5 kg of lime should also be applied to reduce root diseases and promote plant growth. In short, if soybeans want to obtain high yield and high efficiency, scientific management must be strengthened and fertilization water should be used to prevent pests and diseases, and achieve high and stable yield. 3. Key points of open field cultivation techniques Selected varieties: Bean Crown, Gypsophila, Shenlong Jade, Big Grain Fragrant, Kaiyu No.9, Emerald and other mid-ripening varieties. 1. Seeding The middle-mature varieties adopt the hole-seeding method, sowing 3-4 seeds per hole, the spacing between the rows is about 30-35 cm, the shallow holes are thin, and the depth is the same (3 cm deep). After emergence, fill up the vacancy and thin the seedlings in time to ensure that all the seedlings are complete. After sowing, under the premise of moist soil, spray with pre-emergence herbicide (such as rasso, Durr, Henes), and then level the ground. 2. Field management ①The edamame should be chased urea 1-2 times depending on the growth of the plant during the budding stage or the initial flowering stage. The dosage is 5 kg/mu each time and spread around the crops. Use "Bean Amuse" during the blooming period and the pod-setting period, and use 75ml leaves per acre. Spray twice on the surface to improve the photosynthetic capacity of the leaves, reduce the falling flowers and pods, and promote the filling and soybean grain expansion. From the emergence of the soybean seedlings to the harvest, the effect of spraying "Dundou Le" during the whole growth period is more accurate. ②Prevent overgrowth: overgrowth leads to no flowering or early blooming, no pods or too many pods, and should be controlled as appropriate to prevent wild growth (before the rainy season, after flowering, the plants grow too high or too fast or spray the Sichuan Academy of Agricultural Sciences during the blooming period. Produced "short tons" 1-2 times). After the emergence of edamame, the field soil should be kept dry and wet alternately. The furrow should not accumulate water. According to the characteristics of bulging, more water is required in the early stage of pod and bulging. Pay attention to irrigation. At the end of bulging, less water is required to avoid flooding. Promote fullness of grains. 4. Precautions and seed storage methods Please do a test of the germination rate within 15 days after purchasing the seeds. After the germination rate is qualified, many farmers plant seeds in batches for a long time. It is advisable to expose them for 2 hours in the morning from 8 to 10 on a sunny day from February to April. Choose sunny weather from May to June, which is cloudy. It is advisable to expose for 2 hours at 7-9 in the morning (not to expose to the sun) so as not to affect the germination rate. Before sowing, please use soybean seed dressing agent to dress the seeds to ensure that the seedlings are uniform and strong. After dressing the seeds with a small amount of water, the seeds can be sowed without sticking to your hands for about 30 minutes to 1 hour. Please wear rubber gloves to prevent the seeds from being planted on the same day. For poisoning, it is advisable to mix 30 kilograms of seeds with 1 bottle of medicine. Please pay special attention to prevent moisture when storing the seeds. Do not store the seeds directly on the ground. Please put them on the bench. ***Store the seeds in a cool, dry and ventilated room. Remember to choose a good water source when planting from May to June. , Planting in fertile soil, avoid high temperature, lack of water, and lack of fertilizer, which may cause short plants and affect yield.
