The spring soybean varieties that have been approved in recent years include Zhechun No. 5, spring vegetable bean introduced bean 9701, autumn soybean Zhejiang Qiudou No. 2, Zhejiang Qiudou No. 3, and Qiu Qiu No. 1 and the characteristics of these new varieties are now presented. And cultivation points to introduce: First, the new spring soybean variety ----- Zhejiang spring No. 5 This variety is a medium-ripening spring soybean, the whole growth period of about 100 days, Asian limited habits. Plant height 50-60 cm, main stem 12-16 sections. The lower part of the leaves is larger and oval-shaped; the middle and upper parts are smaller, gradually becoming lanceolate, and the leaves are delicate. Large plant type, white flowers, light brown hair. Seed yellow brown light umbilical, 100 grams weight about 20 grams. The average yield is about 125 kilograms per mu, which is more than 5% higher than Zhechun No. 3. High protein and fat content, suitable for processing soy products. Cultivation techniques: 1. Early sowing. When the temperature stabilizes at 10°C in late March, it is necessary to catch early sowing so that the root system will develop early and the lower stalk will be short and thick, which will help form a high-yield skeleton and bring about the potential for yield increase. 2. Sparsely planted. The strain had a slightly higher plant height than Zhechun No. 3. It had a more prosperous growth, with an average density of 16,000 per acre. The planting pattern could be 40*20 cm with 2 plants per hole. 3. Rational fertilization: This species requires a wide range of soil fertility, and can be planted both in fields with good fertility levels and in low-fertility red and yellow soils. In fertile medium fields, it is generally possible to apply 5 kg of pure nitrogen, 3-4 kg of phosphate fertilizer and 3-4 kg of potassium fertilizer. Second, the new varieties of fresh soybeans ---- cited bean 9701 The species ripening earlier, in early April sowing, harvest in mid-June, sowing to harvest only 73 days, 5 days earlier than the dwarf pinnarea. Plant height 30-35 cm, more compact plant shape, oval leaves, dark green leaves, handsome, growing more prosperous. The bottom louse is 9.1 cm tall, with 1.9 effective branches per plant, effective pods of 17.5 pupa, and 33.2 grains per plant. Fresh medlar dark green, white hair, pods 1.3 cm wide, 4.9 cm long, large grain large, fresh oyster shell more glutinous, two or three pods more, a high rate of seeds, one hundred and fresh weight 220-230 grams. The pods are steamed, crispy, sweet and have a good flavor. More resistant to low temperature, facilities cultivation can achieve early sowing, early harvest. Cultivation techniques: 1. Timely sowing. The cultivation of small arches can be planted from the end of January to the beginning of the month. Mulching seedlings can be planted in the middle or late March. Live direct seeding can be in early April, and mulching technology can be planted in early March. 2. Reasonably dense planting. The bean 9701 has a compact type with few branches and should be densely planted. The general density is in the range of 2–2.3 thousand plants/mu. The earlier the sowing date, the more densely planted and the seedlings transplanted can be appropriately thinned. 3. Increase fertilizer to promote early hair. The seedling growth of this variety is not very strong, and it is crucial to promote early-onset development. Fertilization follows the principle of “applying basic fertilizer, applying early Miaofei, skillfully applying flower fertilizer, and supplementing grain fertilizerâ€, and pay attention to increasing phosphorus and potassium fertilizer, generally before sowing. - 15 days Mushi domestic compound fertilizer 50 kg. In the Qimiao and the first compound leaf stage, topdressing urea was 5 kg. The early flowering period was followed by 7.5 kg of imported compound fertilizer, and the young crop stage was topped with 5 kg of urea. Third, the new varieties of autumn soybeans - Zhejiang Qiudou No. 2 earlier maturity of this species, the whole growing period of 95.7 days. The yield is good, and the average yield per mu is 130 kg, which is more than 10% higher than Liqiu 2. Limited knot habits, plant height 49.4 cm, 13.3 main stem internodes, number of branches 2.7, leaf oval, small, lighter leaves, open purple. The effective number of pods per plant is 33.3, and the pods are good. Grain oval, yellow, brown umbilical, 100 grams weight 27.9 grams. Protein, fat, medium content. It is suitable for the cultivation of autumn soybean in the moderately fertile land in the province. Cultivation techniques: 1. Appropriate sowing: It is advisable to use July 15-30 in the province. Outside of this period, early broadcasts are prone to lodging, and late seeding will not be able to exert the variety due to inadequate vegetative growth. 2. Reasonable dense planting: 1.2-1.5 million plants per mu should be appropriate. 3. Scientific fertilizer: This type of fertilizer is resistant to lodging. The use of fertilizers in the production should be based on basal fertilizer. 50 kg of cake fertilizer or 15-20 kg of compound fertilizer per mu should be used to top-dress fertilizers or use top-dressing fertilizers. When overgrowth occurs, uniconazole can be controlled by spraying at the early flowering stage. 4. Field management: timely cultivating and weeding, controlling leaf-feeding insect pests, and earth-cultivation before flowering to prevent lodging at later stages. Fourth, new varieties of autumn soybeans - Zhejiang Qiudou No. 3 The whole growth period of 98.5 days. Limited knot habits, compact plant type, plant height 45.2 cm, the main stem is more robust, internode number 11.3, number of branches 1.75, leaf oval, medium size, gray hair, white flowers. The effective number of pods per plant is 25.3, with medium scarring, large pods, two pods, and gray tan. Grain oval, yellow, navel light brown, 100 grams weight 30.7 grams. In the 2000 and 2001 provincial autumn soybean regional trials, the average yield per mu was 113.2 kg and 134.2 kg, respectively, which was 8.8% and 27.4% higher than the control variety Liqiu 1, respectively, reaching significant and extremely significant levels of yield increase. In 2002, the average production per mu was 116.1 kg, an increase of 11.3% over the control. The protein content is high at 42.6% and the oil content is 18.3%. The variety showed resistance to fertilizer and lodging, large grains, and good yield. It is suitable for the cultivation of autumn soybean in the moderately fertile land in the province. Cultivation techniques: 1. Suitable sowing: early sowing in the mid-July period, early sowing is conducive to promoting the growth of the individual vegetative body of the variety, make full use of the characteristics of the main stem stout, resistance to fertilizer, and promote the high yield. 2. Reasonable dense planting: Density 1.0-1.5 thousand per acre varies depending on the sowing date and soil fertility. 3. Scientific fertilizer: This type of fertilizer is resistant to lodging, and fertilization is based on the principle of using base fertilizer as the main component and taking care of the former and the latter. Specific use of basal fertilizer with 50-80 kg of cake fertilizer per mu or 20-30 kg of compound fertilizer, urea 5-8 kg per acre applied to the branching period, began to flower topdressing or top dressing. 4. Field management: timely cultivation, weeding, and control of leaf-feeding pests. 5. New varieties of autumn soybeans - Qiuqiu No. 2 The whole growth period of this variety was 102.3 days. Limited knot habit, plant type upright and compact, plant height 54.8 cm, the main stem is more robust, the number of internodes 12.7, elliptic leaves, medium size, purple, gray hair. The medium branching rate was 2.3; the number of single plants was 31.3, and the mid-cocoon stage was dominated by two plants. The seed coat is green, the umbilicella is light brown and the hundred kernels weigh 31 grams. In 2000 and 2001, the average yield per mu in the provincial autumn soybeans was 116.9 kg and 125.3 kg, respectively, which was 12.1% and 19% higher than the control variety Liqiu 1, respectively, both of which reached extremely significant levels of yield increase. In 2002, the average production per mu was 124.8 kg, an increase of 19.7% over the control. The protein content is 43.4% and the oil content is 18.7%. The variety showed resistance to fertilizer and lodging, and good yield. Suitable for the autumn soybean cultivation in the province. Cultivation techniques: 1. Timely sowing. The suitable sowing period is from mid-July to the end of July, timely sowing will be beneficial to the formation of high-yield stands, and the potential for high yields will be brought into play. 2. Closely planted. The plant type of this species is relatively compact, with a density of 1.2-1.3 million per acre. The planting method adopts a wide-row narrow plant with 2 plants per hole. 3. Scientific fertilization. Fertility medium fields, generally 6-7 kilograms of Mushi pure nitrogen, 4-5 kilograms of phosphate fertilizer, potassium about 4 kilograms. 4. Cultivate soil to prevent lodging. Soaking deep-medium cultivating soil before sowing in the field of soybeans will promote the growth of roots and prevent lodging. For instance, the phenomenon of leggy in Daejeon can be used to spray 50ppm uniconazole solution 50kg/mu at the beginning or full flowering stage.
