What are the cultivation characteristics of greenhouse fall/winter cultivation patterns for peppers? What is the application situation?

Pepper greenhouse fall and winter cultivation mode is usually selected improved solar greenhouse or ordinary solar greenhouse as a protective facility, the selection of early and medium-maturity pepper varieties. North China is generally sown in July seedlings, planted in September in the greenhouse, to take the new method of pruning technology for dense planting. Under normal management conditions, the harvest began to market in October to November, the main supply of November to the Spring Festival for a period of time.

Chili greenhouse fall and winter cultivation mode of the main supply period for the late fall and early winter, this period is at the end of the supply of plastic greenhouse chili, greenhouse winter and spring crop of chili supply before the market supply off-season, the market price is higher, the cultivation benefit is better, the general income of each 667 m 2 less than a few thousand yuan, more than 10,000 yuan.

Chili greenhouse fall and winter cultivation mode of the main drawbacks are:

(1) higher production costs at present, the construction of a cultivation area of 667 m 2 of the ordinary soil and bamboo wire structure of the improved solar greenhouse requires an investment of about 10,000 to 15,000 yuan, the construction of an ordinary solar greenhouse also requires capital of 6,000 to 8,000 yuan, the construction of greenhouses is relatively high cost. In addition, to maintain the greenhouse chili cultivation annual production investment needs more than 2,000 yuan. According to the greenhouse period of 5 years discount, the annual production investment of at least 3000 yuan, so the greenhouse pepper production costs are relatively large. (2) Cultivation and management techniques are complex, the cultivation effect is greatly affected by the production conditions and climatic conditions of the greenhouse greenhouse fall and winter cultivation mode of chili pepper seedling period is in the hot and rainy summer, the period of higher temperatures, small temperature difference between day and night and humidity is also larger, chili pepper seedling growth is faster, easy to grow, but also easy to die of disease, the difficulty of seedling raising is relatively large. The fruiting period of this cultivation mode is mainly in the cold and low-light winter, the environment in the greenhouse is not suitable for the growth and development of chili peppers, plant growth is poor, not easy to sit, deformed fruits, the color of the fruits is also lighter, poor commercial quality, and chili pepper diseases are also more serious, easy to occur early failure. Therefore, the management of pepper greenhouse fall and winter cultivation mode is more complex, and more strict in the specific requirements of management.

At present, pepper greenhouse fall and winter cultivation mode is mainly used in the suburbs of large and medium-sized cities and some outside the transport of food-based greenhouse pepper production areas, is one of the important cultivation stubble of the two-crop system greenhouse cultivation area.
