What season is cotton?

Cotton originated in tropical and subtropical regions and is a perennial short-day crop. After long-term artificial selection and cultivation, it gradually moved north to the temperate zone and evolved into an annual crop. When sowing in spring (or early summer), it germinates, blooms and bears fruit that year, completing its growth cycle. When the cold winter comes, its life is over. Cotton likes heat, light, drought and waterlogging, and is suitable for planting in winter. As long as there are enough conditions of temperature, light, water and fertilizer, just like perennial plants, they can continue to grow and develop, and grow branches, leaves, buds, flowers and bells. They have unlimited growth and strong regeneration ability. In the life of cotton, temperature has a great influence on its growth, yield and product quality. Apart from temperature, cotton is very sensitive to light, relatively drought-resistant and afraid of waterlogging. From the vernal equinox to the 16 solar term in beginning of winter (from the middle and late April to the middle of 1 1 month), the whole life can be divided into five stages: sowing stage, seedling stage, bud stage, boll opening stage and boll opening stage. Compared with other agricultural products, cotton has a long growth period and is greatly influenced by natural factors.
