The off-season vegetable cultivation refers to the use of special facilities and techniques to produce vegetables in the season when it is impossible to normally grow certain vegetables. Compared with normal vegetable production, the production and marketing periods of off-season vegetables are earlier or later than normal, so the essence of anti-season vegetable cultivation is to advance or postpone cultivation. Here are 6 common off season vegetable cultivation types: 1. Overwintering cultivation: Using wind barriers, plastic sheds to cultivate cold-resistant vegetables in winter, wintering under protective equipment, harvest early in the early spring, such as windbreaks, spinach, leeks, etc., winter sheds spinach, rapeseed, alfalfa, sheds Celery, leeks, etc. 2. Early-maturing cultivation: use protective equipment (such as cold insulation or shading and cooling) to protect against cold and warm, early planting to obtain early maturing products. 3. Delayed cultivation: sowing in summer and planting in protective equipment in autumn to extend the growing period and supply period of vegetables. 4. Summer cultivation: During the high-temperature and rainy season, shading, cooling, rain protection and other protective measures are carried out using shade and arbours to cultivate in the summer. 5. Promote cultivation: In the cold season, use a greenhouse for warming cultivation to promote the product. 6.
