What vegetables are grown in April in the north? Introduction of Vegetables Suitable for Planting in April in North China

1, beans are planted at the right time. Generally speaking, beans like warm climate and are not cold-tolerant. The optimum temperature for seed germination is 25-30℃, and it is difficult to germinate below 15℃. The optimum temperature for seedling stage and pod growth is 15-30℃. The period from planting beans to harvesting is generally about 60 days, which is just the summer harvest of spring planting. In addition to beans, other beans such as edamame, peanuts, mung beans and black beans can be planted at this time.

2, leafy vegetables are harvested quickly. Spring is the best time to plant leafy vegetables. Generally speaking, leafy vegetables like a warm and slightly cold climate. Too long light time and too high temperature can easily lead to bolting of leafy vegetables. Planting leafy vegetables in the solar term from Qingming to Grain Rain can be summarized as "two quick and one long", that is, quick emergence, fast growth and long picking period. The recommended leafy vegetables are coriander, fennel, lettuce, oily wheat, chrysanthemum, malachite and sesame.

3. Tomato colonization now. Tomatoes are planted in early spring and transplanted in late spring. Tomatoes are cold-resistant but not frost-resistant. Plants below zero will die, and it is difficult to bear fruit at high temperature in summer. Therefore, tomatoes are generally transplanted in late spring, set fruit in early summer and harvested from midsummer to autumn.

It's not too late to raise pepper seedlings. Pepper is resistant to heat and cold. The optimum temperature for seed germination is 25-30 degrees, and the optimum temperature for seedling growth is 18-30 degrees. When the temperature is lower than 15 degrees, the pepper will grow poorly. Therefore, pepper seedlings are raised in late March and early April in the north, and the seedling stage is generally one month. It is more suitable to transplant to vegetable garden in May.
