The Latest Introduction to Cabbage Planting Time
The scientific name of cabbage is head cabbage (Brassica oleracea var. capitata), native to the Mediterranean region of Europe. It is now widely cultivated throughout our country and is one of the common vegetables. Its requirements for planting time and environmental conditions are not strict. Let us take a look at the planting time of cabbage together below!
Cabbage Planting Time
Cabbage has strong adaptability, tolerating both cold and heat, and can be cultivated in the open field in spring, summer and autumn in northern China. In the high-cold regions of Northeast China, Northwest China and North China, seedlings are mostly raised in spring and summer, planted in summer and harvested in autumn, with a long growth period and large heads. In North China and some cities in Northeast and Northwest China, spring and autumn crops are the main cultivation seasons, and multiple cropping is also possible.
Cabbage Planting Density
1. Early-maturing varieties: plant spacing of 33-40 cm, 4000-6000 plants per mu.
2. Mid-maturing varieties: plant spacing of 45-50 cm, 2500-3000 plants per mu.
3. Late-maturing varieties: plant spacing of 60-65 cm, 1500-1800 plants per mu.
Cabbage Planting Conditions
Cabbage has basically the same environmental requirements as Chinese cabbage, but it has broader adaptability and somewhat stronger resistance than Chinese cabbage.
1. Temperature: Cabbage prefers a mild climate and can withstand severe frost and fairly high temperatures. The suitable temperature during the head-forming period is 15-20°C, but the adaptable temperature range is 7-25°C. Seedlings can endure low temperatures of -15°C and high temperatures of 35°C.
2. Soil: Cabbage requires sufficient soil moisture and humid air. If the soil is dry, it will affect head formation and reduce yield.
3. Light: Cabbage is a long-day crop and has wide adaptability to light intensity, with a light saturation point of 30000-50000 lx.
4. Fertilizer: Cabbage is a fertilizer-loving and heavy-feeding crop, absorbing a large amount of nutrients. It needs more nitrogen fertilizer during the seedling stage and rosette stage, and more phosphorus and potassium fertilizer during the head-forming stage. The ratio of nitrogen, phosphorus and potassium absorbed throughout the growing period is about 3:1:4. For every 1000 kg of heads produced, it absorbs 4.1-4.8 kg of nitrogen, 0.12-0.13 kg of phosphorus and 4.9-5.4 kg of potassium. On the basis of applying sufficient nitrogen fertilizer, combined application of phosphorus and potassium fertilizer has an obvious yield-increasing effect.
