Sweet pepper can be divided into autumn greenhouse cultivation and early spring greenhouse cultivation. In early spring, seedlings were cultivated in greenhouse, which began to emerge in the middle of June 5438+1October, and could be sown in the middle of June 5438+February, and harvested in the middle of March of the following year. Postpone overwintering greenhouse cultivation in autumn, raise seedlings in mid-August, sow in mid-June at 65438+ 10, and harvest in mid-June of the following year.
Planting time of southern sweet pepper: sweet pepper planted in southern China can be planted in June 5438+ 10 every year.
Planting time of northern sweet pepper: The planting time of northern sweet pepper is between the middle and late April, mainly depending on the climate and geographical environment.
Sweet pepper producing area
The producing areas of high-quality sweet peppers in China are mainly in the north, such as Shanxi, Shandong, Inner Mongolia, Jilin and Heilongjiang.
Sweet pepper planting method
1. Seedling cultivation: transplant the seedlings into large cultivation containers as soon as possible after purchase, and water them every morning 1 time. After the rainy season, water 1 time in the morning and evening.
2. Chajia: When plants grow to 20-30 cm high, it is necessary to set up a bracket with a height of 50 cm. The branch of the 1 flower is the main branch, leaving the main branch and two axillary buds under the flower, and removing all the others. It takes about 1 month from flowering to fruiting to harvesting.
Key points of sweet pepper planting management
1. Temperature and humidity: The temperature and humidity control of sweet pepper is mainly divided into slow seedling stage and before flowering. After planting in the slow seedling stage, the temperature should be kept at 28-30 degrees during the day and not lower than 25 degrees at night. After the slow seedling stage and before flowering, the temperature is 20-25 degrees during the day and 18-20 degrees at night, which can avoid excessive growth caused by high temperature and high humidity.
2. Fertilizer and water management: the soil needs relatively high humidity, so drip irrigation can be used. Fertilize the bottom branches immediately after flowering. During the fruit-bearing period after flowering, nitrogen, phosphorus and potassium fertilizer are applied to each batch of sweet peppers once until the fruit is finished, and then farmyard manure is applied later.
