How many months can zucchini be planted?

Spring or autumn sowing, spring sowing in March, autumn sowing in September. Cultivation methods are divided into open field, simple ground cover and protected field cultivation (also divided into small arch shed and greenhouse cultivation), each with its own characteristics.

Planting method:

Remove impurities, select clean and plump seeds with a thousand-grain weight of about 200g, put them into a clay pot or other oil-free container, soak them in cold water first, then blanch them with warm water at 50-55℃, keep stirring constantly, keep 15-20 minutes, naturally cool them to 20-30℃, soak them for 4-6 hours, and take them out and use 65438. Air-drying, heating to accelerate germination when semi-drying, and the appropriate temperature is 25℃. If the seed quantity is large, it can be turned over during germination to promote orderly germination, but it will not be turned over after germination.

When the bud length is about 1.5cm, we should choose sunny and warm weather for sowing. If you can't sow in rainy days, you can put the seeds in a cool place to control the growth of buds.

Sowing nutrient soil should be prepared 20-30 days before sowing. Selecting disease-free soil and farmyard manure without planting melons and vegetables for preparation. Usually, 6 parts of garden soil are mixed with 4 parts of rotten horse manure or manure. Put it in a seedbed, paper bag or plastic bowl (9- 10㎝) with a thickness of 8-9cm. Cover the soil about 2 cm after sowing.

Seedlings are easy to grow in white, so temperature and humidity should be strictly controlled. After sowing, the seedlings should be kept at a high temperature before coming out of the soil layer, with the daytime temperature of 25-30℃, the nighttime temperature of 18-20℃, the ground temperature of 22-24℃ and the relative humidity of 80-90%, and the seedlings will emerge in about 3-4 days. After the seedlings come out, they should be properly cooled and ventilated. The daytime temperature is about 25℃, and the nighttime temperature is 13- 14℃. After the first true leaf is unfolded, the nighttime temperature drops to 12℃. 8- 10 days before planting, the ventilation rate should be gradually increased, and the seedlings should be exercised by cooling, generally 15-25℃ during the day and 6-8℃ at night.
