1. Kelloji (commonly known as cabbage or cabbage): The most suitable temperature for the seed germination of Ganlan is 15-25°C. The sowing is generally around the beginning of August, such as the slow Ganlan and Xinfengganlan in April. Concentration, too early sowing because of high temperature affect the emergence of seedlings, too late sowing affect the growth and development of the crop, the ball and yield. The seedlings mastered 35-45 days, and in the middle or late September, 5-6 true leaves were transplanted with soil. 2, radish: radish seed germination the most suitable temperature is 20-30 °C, sowing is generally in mid-August to mid-September, especially in late August as the most suitable sowing date. The use of hole sowing, acres with the amount of 0.75-1 kg, divided 2-3 times between the seedlings, spacing of 2545 cm; using drill or sowing, mu seed amount of 1.25-1.5 kilograms, Dingmiao master line spacing 1515 cm. 3. Cauliflower (commonly known as cauliflower): The optimum temperature for broccoli seed germination is 20-25°C. Usually in August, early maturing varieties such as Ruixue Extra 60 days and Ruixue Extra 70 days, can be sown as early as July, but pay attention to the high temperature In the case of weather, cool and moisturizing measures are taken; middle and late-maturing varieties are more suitable for local planting, seedling transplanting, and seedling ordering for 30-35 days. 4. Lettuce: The most suitable temperature for the germination of lettuce seeds is 15-20°C. If the temperature exceeds 25°C, it will not be easy to germinate. If it is less than 10°C, it will not be easy to germinate. There are many varieties of lettuce, which have a wide growing season and long sowing time. For the main varieties of autumn, such as heat-resistant white-leaf lettuce, wells, refrigerators or other low-temperature treatments are used to germinate in high temperature season, otherwise it is difficult to guarantee the success of nursery; for autumn and winter varieties Such as cold-resistant silk red, later sowing in the cold season (long 8 °C below), the plastic film should be adopted small greenhouse insulation seedlings; for the four seasons main varieties such as oil and wheat dish (commonly known as lettuce) as long as the appropriate germination temperature, ready for seedlings. It is best to soak in fresh water for 3-4 hours before germination, which is conducive to budding and tidying. Seeding is generally conducted in mid-to late September and early October to cultivate strong seedlings and transplant them with soil. 5, cabbage, vegetables: cabbage, vegetables (including wok vegetables, all kinds of vegetables) the best temperature for seed germination 15-25 °C, this type of vegetables, short growing period, planting is generally easy and long sowing time. In general, local sowing begins before and after the beginning of autumn. Early-maturing and heat-tolerant varieties such as early-maturing Chinese cabbage No. 5, early sowing and early-vegetable sowing, and early sowing of cabbage seeds are used as edible cabbage. Before and after the National Day, the temperature is moderate, according to the growth period of different species, thin-seeding cultivation; strong seedlings can also be nurtured, transplanted and planted, and the age of seedlings can be grasped for about 30 days. 6, mustard: Mustard seed germinate the most suitable temperature 15-25 °C, this kind of vegetable is autumn overwintering crops, long growth period, local suitable sowing period in late September to early October. Such as stem mustard mustard, sowing early planthoppers are more likely to spread viral disease, while part of the above-ground part of the nutrient growth, fleshy stems began to expand, winter low temperature and easy to freeze; sowing late plant development is poor, susceptible to freezing and affect the yield . Age of seedlings is 35-40 days, and 5-6 leaves are planted in Daejeon.
