10, gold medal national mention: the plant is infinite growth type, with moderate growth potential, high fruit setting rate and rapid fruit expansion. Compared with L402, Maofen 802 and Shanghai 908, it was earlier 15 days, with an increase of 30-50% and a total output of 20%. The fruit is pink, round, bright in color, without green shoulders, weighing 300 grams, thick in meat and hard in fruit, and resistant to long-distance transportation. High resistance to tobacco mosaic virus, leaf mold, moderate resistance to gray mold, late blight and so on. Key points of cultivation: this variety likes water and organic fertilizer, and its squatting time is short. During the whole growth period, fertilizers such as calcium, magnesium and boron are applied together. Tomato enters the flower bud differentiation stage when the two leaves are United, and the 2-6 leaf stage is the key period for the first inflorescence to differentiate into the third inflorescence. At this time, if the temperature at night is lower than 12 degrees for a long time, it is easy to form deformed flowers, leading to deformed fruits and cracked fruits, so we must pay attention to heat preservation. This variety has strong natural fruit-setting ability and low concentration at flowering, which is 1/2- 1/3 of the common variety. The concentration of flowering should be adjusted at any time according to the change of temperature. It is best to point the colored hormone on the fruit stalk when there is no dew in the morning and evening. When cultivated in summer and autumn, leaving three functional leaves on the top ear fruit can increase photosynthesis and protect the fruit surface from strong light. Shaanxi Datang Seed Industry Co., Ltd. Datang brand varieties.
1 1, Kuiguan 1No.: high seedling and powdery fruit, outstanding early maturity, thin and medium leaves, high photosynthetic efficiency, strong fruit-setting ability at low temperature and weak light, rapid fruit expansion and high early yield. The fruit has no green shoulders, uniform size, high and round apple shape, smooth and shiny skin, no deformed fruit and cracked fruit, thick skin and good storage and transportation resistance. High resistance to tomato mosaic virus leaf mold and Fusarium wilt, low incidence of gray mold and late blight, suitable for solar greenhouse, greenhouse early spring, late autumn, spring open field and summer sowing cultivation. Cultivation points: new seeds are dormant, and airing before sowing can promote germination; 2. 2-6 leaves of seedlings differentiate into flower buds, and pay attention to heat preservation. At night, the temperature should not be lower than 12℃, with 2,500-3,000 plants per mu in early spring, 2,000-2,500 plants in late autumn, 3,500-4,000 plants in spring and 2,500 plants in greenhouse. Pay attention to the application of bioactive calcium fertilizer, magnesium fertilizer and boron fertilizer with high fertilizer, avoid too low ground temperature after planting, advocate keeping vegetative branches in the early stage, changing heads and pruning in the middle and late stage, and the concentration of point flowers should be light, the general variety is 1/2- 1/4, and the concentration should not be high under low temperature and weak light, otherwise the fruit will crack. Xi Anchangfengyuan Seed Industry Co., Ltd. was awarded the title of "Kuiguan" brand.
12, Maofen 608: a substitute variety of Maofen 802, which is a hybrid with infinite growth type and middle-late maturity, bearing the first inflorescence in the 8th-9th section, with strong growth potential. Two-thirds of the plants are densely hairy, and the fruit is pink, round, good in quality, high in fruit setting rate, high in yield, resistant to virus disease, leaf mold and epidemic disease. The number of seedlings per mu is 3200. Because of the vigorous growth of this variety, it is necessary to strengthen fertilizer and water management, adopt single stem pruning and continuously change heads to enhance resistance.

The early yield was 30-50% higher than the variety, and the total yield was about 10%. It is the earliest variety with unlimited growth and maturity at present. 3. Good comprehensive resistance: high resistance to tomato mosaic virus, moderate resistance to cucumber mosaic virus, high resistance to leaf mold and Fusarium wilt, gray mold and late blight, low incidence, and good resistance to weak light and heat.
Practice point: 1. Expose the seeds for several hours before sowing to promote germination. The seedbed should be kept warm and moist, and the temperature at night should not be lower than 12 degrees, otherwise the flower bud differentiation will be poor, and the sowing amount will be 30g/ mu. 2. Generally, 3,500-4,000 plants are planted per mu in greenhouses with three to four ears of fruit stones in spring, 3,000-3,500 plants per mu in greenhouses in early spring, about 3,000 plants per mu in greenhouses in late autumn and 2,500 plants per mu in greenhouses in winter. 3. Re-apply base fertilizer, apply topdressing early and use bio-organic fertilizer. At the same time, pay attention to calcium, magnesium and boron fertilizers. The concentration of flowers should be light, the redundant lateral branches should be removed in time, 3-4 fruits should be left per ear, and 3-4 ears should be left for head-to-head pruning cultivation, so that 6-8 ears of high-quality big fruits can be harvested.
14, Tianyuan 1No.: This variety belongs to the infinite growth type of middle and early maturity, with vigorous plant growth, strong fruit setting rate, bright pink fruit, beautiful, smooth and without green shoulders, large and uniform fruit, with an average single fruit weight of 300-500 grams, a maximum fruit weight of 800 grams and a yield of 6544 per mu.
