In the early spring of March, the temperature began to warm up slowly, the light rain began to appear, and the spring ploughing began slowly. So which vegetables are suitable for growing in March 2020?

What kind of fruits and vegetables are suitable for planting in early spring?

Early spring is the greenhouse tomato, pepper, eggplant, cucumber, bottle gourd, zucchini and other early-maturing fruits and vegetables into the flowering and fruiting period management; it is also the time to sow seedlings and plant vegetables in the open field. At this time, some crops in melons, eggplant fruits, legumes, cabbages, root vegetables, potato potatoes, green leafy vegetables and aquatic vegetables should be sowed or planted in March, which is related to the supply and income of vegetables in the first half of the year. At the same time, all kinds of overwintering vegetables begin to grow again, and field management needs to be strengthened.

(1) fruits and vegetables suitable for raising seedlings

1. If it is a vegetable in a plastic shed, you can sow winter gourd, pumpkin, balsam pear, bottle gourd, towel gourd and other gourd vegetables in a cold bed in the first and middle of March. Winter gourd can choose Guangdong Qingpi wax gourd, Hunan powdered wax gourd, Qingza No. 1, Fanza No. 1, etc.; bitter gourd can choose Lvxiu balsam pear and Chunxiu series varieties; pumpkin can choose honey pumpkin, yellow wolf pumpkin, a string of green pumpkins, persimmon pumpkins, red chestnut pumpkins, etc.; pumpkins can choose Hanlong Qingyu, Jasper and so on.

2. Late-maturing pepper seedlings can be sown in late March, according to the technical requirements of conventional seedling raising in the open field.

(2) fruits and vegetables suitable for sowing

Direct seeding vegetables include radish, chrysanthemum, cumin, Bombyx mori, bamboo leaf, amaranth, lettuce, cabbage and dwarf beans.

(3) fruits and vegetables suitable for planting

Zucchini can be planted in early March, with a row spacing of 1 m * 0. 45 meters. When the ground temperature at the depth of 5 cm is more than 10 ℃, the sunny day with cold tail and warm head, plastic film mulching or small arch shed mulching cultivation, mulching plastic film one week before planting is beneficial to increase the ground temperature. Other eggplant fruits and melons can continue to be planted.

II. Field management

During the flowering and fruiting period, the temperature in the greenhouse should be less than 30 ℃ during the day and more than 15 ℃ at night to prevent falling flowers and fruits, and the daytime temperature should be 26-28 ℃. After the middle of March, you can uncover the small arch shed, insert the frame (or hanging vine) and tie the vine when the seedling is 30 centimeters high, and then bind the vine every 3-4 leaves. Pruning is mostly single-culm pruning, leaving 4-5 spikes, 2-4 fruits per panicle, and removing other twigs and flower buds. You can put bumblebee pollination in the shed or spray flowers with 15-20 mg / L 2,4-color D liquid or 30-40 mg / L anti-falling hormone solution to protect flowers and fruits, pay attention not to repeat points or spray, fruits should be thinned properly after sitting down. When the first ear is seated, water it once, and then water it every 6-7 days. Watering should be carried out in the morning on a sunny day, and the shed should be closed to raise the temperature after pouring. The next morning and noon should be ventilated and drained in time. 1500 kg of rotten manure was poured before hanging vines or shelves, and 15 kg of urea was applied when each ear began to expand. Pay attention to the prevention and control of early blight, Botrytis cinerea, virus diseases and insects. The cultivation of pepper and eggplant by adjusting temperature and humidity is basically the same as that of early-maturing tomato.

Cucumber is mainly heat preservation and anti-freezing before the end of March, covered with four layers of greenhouse, grass curtain, small shed and plastic film, and properly ventilated during the day. After the small arch shed is removed later this month, the scaffolding or hanging vines will be built. Topdressing should grasp the principles of early, diligent and skillful, so as to promote the early development, moderate stability and later health of the plant. After sprinkling dilute manure water at seedling stage for 2-3 times, urea was generally applied with water every 7-10 days, 10 kg per mu or 1500 kg of rotten human feces and urine. 0.2% Mel 0 was sprayed on leaves every 5-7 days during the whole growth period. 3% potassium dihydrogen phosphate solution. Watering should be controlled before the results, and watering should be done every 10 days at the initial stage. Attention should be paid to the control of downy mildew, powdery mildew, blight, Fusarium wilt, bacterial angular spot, root-knot nematode, Huangshou melon and aphids.

The temperature and humidity management of bottle gourd after planting is the same as that of cucumber precocious cultivation. Pay attention to the method of using ethephon to treat or pick the main vine to promote the lateral vine to bear melon. The temperature and humidity management of zucchini after planting is the same as that of cucumber early maturing cultivation.

There are many fruits and vegetables suitable for planting in early spring. I hope you can seize the good time to plant in spring to welcome this bumper harvest year.
