I. Introduction 9G-04 Newly bred early-maturing summer-autumn cabbage varieties. Summer planting is harvested for 55 days, and autumn planting is harvested for 65 days. The plants were developed at about 55 cm, with 13 outer leaves, oval-shaped leaves, green leaves, medium leaf wax, dense leaf ball, and thick round oblate, weighing 1.2 kg. The leaf veins are fine, the ball is green, and the commodity is excellent. It is suitable for base production in all parts of China. In the Yangtze River valley, it can be planted from late June to early August. It can also be planted from January to March, with 5 to 6 true leaves colonized and harvested 60 days after planting. 9G-05 Newly bred new varieties of summer cabbage. The plant development degree is about 60 cm, the outer leaves are grayish green, the wax powder is spherical, and the single ball weighs 1.5 kg. The ball is resistant to cracking, and it will not crack after two weeks. Fifteen outer leaves, 15 cm in height and 17 cm in lateral diameter, were planted until harvested for 60 days. They were suitable for the cultivation of the summer and autumn in the Yangtze River basin and the areas south of the Yangtze River. The yield was comparable to that of the control N-2. The disease resistance was stronger than that of the control and the ripeness was similar. Second, cultivation points Brassica oleracea cultivation in summer and autumn, control of seedling age in 35 days colonization, spacing 40 cm 40 cm. At the seedling stage, shade shelters should be used to prevent sun exposure and heavy rain erosion. It is advisable that the soil is moist and the soil surface is slightly dry. When the young seedlings have 3 to 4 true leaves, loose soil once, and 25 days of seedling age for planting. When the seedlings reach 6 to 7 true leaves, the soil is planted on a cloudy day or evening, and the roots are filled with water, and the seedlings are diluted with diluted fecal water. Combination of watering and timely cultivating 2 or 3 times. The use of large-scale water management, mainly nitrogen fertilizer, speed up the growth of cabbage. During the rosette period, 25 kg of urea was applied per acre, combined with watering to keep the soil moist. In the early stage, the growth of plants was faster and the topdressing was applied one time, applying 40 kg of urea per acre to promote the enrichment of the ball. Prevention and control of pests and diseases should be based on prevention measures. Arrangements and cultivars should be reasonably arranged. The planting area should be staggered with the cabbage plantation of the previous crop and neighboring crop to reduce the source of insects. Prone to downy mildew in the seedling stage, 75% chlorothalonil wettable powder can be used to control 500 times. The commonly used drugs for controlling lepidopteran insect pests include: Suppressor 2000 times solution, stuck solution 2000 times solution, 20% fenvalerate 2000 to 3000 times solution, 25% deltamethrin 3000 solution, 20% cleaning Lee Po 4000 times liquid and so on. Third, promote the application of the situation 9G-04 and 9G-05 are the latest summer and autumn special cabbage varieties introduced by Jiangsu Jiangzi Seedling Technology Co., Ltd. The company successfully held a promotion conference for new varieties of cabbage in April 2009, and extensively experimented with species. Currently, it reflects well. 9G-04 shows good commercial appearance in production, sowing flexibility, sowing date can be appropriately extended, is conducive to gargle arrangements; 9G-05 appears mature after crack resistance, according to the market conditions, flexible control of harvest period. At present, these two varieties are in the promotion stage. Fourth, seedlings supply Jiangsu Jiangzi Seedlings Technology Co., Ltd. is a holding company of the Jiangsu Academy of Agricultural Sciences. The 9G-04 and 9G-05 can basically be used for the anniversary. SICHUAN UNIWELL BIOTECHNOLOGY CO.,LTD. , https://www.uniwellbio.com
