What vegetables are planted after spring?

Spring is wet and cold, and the temperature is low. It is suitable for planting celery, potato, lettuce, Shanghai green, onion, pumpkin, pepper, eggplant and other vegetables. These vegetable varieties can germinate and grow under the land temperature of 65438 00℃, and also have certain cold resistance. Spring is the season when everything recovers, and it is also one of the busiest seasons for many growers.

1, celery planting

Celery likes humid and cool climate, and it is a semi-hardy vegetable. It can survive in the low temperature below zero for a short time, but it can't survive in the high temperature. The suitable temperature for celery seed germination is 15℃ ~ 20℃, but below15℃, the germination speed will obviously decrease, and the lowest germination temperature is 4℃, and the seeds will not germinate when it is higher than 30℃. The grown seedlings are green vernalization plants that can survive at the low temperature of -5℃-7℃, and celery seedlings with 3-4 leaves can survive at the vernalization stage of 2℃- 10℃ 10 -30 days.

2. Potato planting

It reproduces asexually through tubers. When the soil temperature is 5℃-8℃, potato buds can germinate and grow, but the grown potato seedlings can't survive below -2℃, which will cause the grown seedlings to suffer from freezing injury. The optimum temperature for potato bud growth is 15℃-20℃, and the soil temperature for tuber growth and development at night is 16℃- 18℃. When the soil temperature is higher than 20℃, potato grows slowly, and the most suitable temperature for potato seedling growth and flowering is 16℃-22℃.

Step 3 grow lettuce

Lettuce is a crop that can't tolerate cold or high temperature. The optimum temperature for lettuce seed development is 18℃-20℃, but it can germinate at the low temperature of 4℃, but the seeds will not germinate above 30℃. Lettuce seedlings grow and develop for 90- 100 days. In their growing period, they like cold climate, so they must make high yield, high quality and suitable temperature.

4. Green planting in Shanghai

The most suitable growth temperature for spring planting is 18℃-20℃, and it grows well in sunny environment. Sandy soil should be selected for planting, which can survive at -2℃-3℃ without being damaged by low temperature. Some varieties of Shanghai Green can be planted in summer, so it is necessary to choose the appropriate season according to the characteristics of the varieties.

Step 5 grow onions

Onion can survive at both low temperature and high temperature, and can adapt to a wide range of temperatures, but the most suitable temperature for onion growth is 13℃-25℃, and the lowest temperature for onion germination can be 2℃-5℃, but the most suitable germination temperature is 15℃-20℃, and the spring time for onion is 7 days-10/.

6. Pumpkin planting

Pumpkins are planted in the Yangtze River valley and South China at different times, which makes them different. Generally, the Yangtze River basin is broadcast live in February-April, mainly in the middle and late March and early February-March in hotbeds or cold beds, but in South China, it can be planted in February-September, mainly in spring in February-March and autumn in August-September.

Soak pumpkin seeds in hot water at 55℃-60℃ for a quarter of an hour to kill bacteria on the seed epidermis. Then the seeds are poured into cold water, cooled to about 30℃ and soaked for about 5 hours. Then wrap the seeds with wet towels or gauze and put them in an environment of 25℃-30℃ to accelerate germination. When the pumpkin buds grow to 0.3cm, you can start sowing.
