When to Sow Cabbage? A Detailed Guide to Planting Time
Cabbage is a vegetable with many varieties, the common ones being broccoli, cauliflower, Chinese kale, and others. It is currently widely distributed across our country, and it can be seen in many regions. Because cabbage is very popular with consumers, many people want to grow cabbage, and the first thing is to understand its planting time.
Cabbage planting time
For cabbage planting time, sow at the right time: early-maturing varieties can be sown from April to June, and for mid- and late-maturing varieties, early June to early August is the best sowing period.
Cabbage planting methods
1. Choose the variety. Choose early-maturing varieties with a short growth period, with a single head weighing about 1 kg, and about 45 days from transplanting to harvest, which is more suited to consumers' habits and does not affect the sowing period of the next overwintering crop, such as the Dutch variety Swiss Multi and others.
2. Sow at the right time. Cabbage seedlings are not strict about temperature, but the head-forming stage is very strict about temperature, which should be around 17°C, as this is favorable for the formation and growth of the leaf head. Therefore, the summer sowing time is around late July. IV. Land preparation and transplanting
3. It is advisable to choose a plot whose previous crop was a non-cruciferous bean or melon crop, apply 3000 kg of decomposed organic fertilizer and 30 kg of nitrogen-phosphorus-potassium compound fertilizer per mu, plow the soil and make beds, with a bed width of 1.2 m, plant 2 rows, with a plant spacing of 40 cm, and keep 2500-3000 plants per mu. Transplant when the seedlings grow to 5-6 leaves. Spray once before transplanting, that is, when the seedlings are clustered in the seedbed, spray once again with 600 times chlorothalonil plus 3000 times Wanling. With proper management after transplanting, generally no pesticide is needed, and basically no disease occurs throughout the whole growth period. The transplanting water should be timely to help the seedlings recover, and the seedlings must not be left to dry in the sun.
Cabbage fertilization techniques
1. Application of base fertilizer. After the previous crop is harvested, apply 3000-4000 kg of barnyard manure per 667 sq m as base fertilizer, plow deeply, rake flat, and make beds 60-66 cm wide and ridges 15-18 cm high. If organic fertilizer is insufficient, after deeply plowing and raking the land flat, apply 1000-2000 kg of decomposed barnyard manure per 667 sq m according to the row spacing, then build ridges and carry out concentrated fertilization, which can better exert the fertilizer effect.
2. Application of topdressing. Rutabaga has the characteristics of being tolerant of fertilizer, tolerant of poor soil, and having strong absorption capacity, but to achieve high yield, fertilizer and water management must be strengthened. During the vegetative growth stage of rutabaga, two topdressings can generally be carried out. After direct seeding and thinning to a stand or after transplanting has survived, carry out the first topdressing, applying 15-20 kg of ammonium sulfate or 50-750 kg of human manure and urine per 667 sq m. During the peak period of fleshy root enlargement, carry out the second topdressing, applying 25-30 kg of nitrogen, phosphorus, and potassium compound fertilizer per 667 sq m, or 100-150 kg of plant ash. 750 kg of human manure and urine. After topdressing, pay attention to watering.
Cabbage pest control methods
1. Cabbage damping-off disease. Control measures: before sowing, dress seeds with 65% mancozeb wettable powder at 0.3% of the seed weight. Disease-free new soil should be used. The seedbed should be chosen as a plot with high terrain, a low groundwater level, and good drainage. Sowing should be uniform, and after emergence, water as little as possible; when watering is necessary, a sprayer can be used to spray and moisten the soil surface, avoiding flooding irrigation. When the seedlings grow to 2-3 true leaves, carry out seedling separation, and it is best to use a seedling shovel when separating seedlings. After seedling separation, control water appropriately and carry out soil covering in stages. After seedlings show disease, immediately pull out the diseased seedlings and spray 25% metalaxyl wettable powder 800 times solution, or 64% oxadixyl · mancozeb wettable powder 500 times solution, or 72.2% propamocarb aqueous solution 500 times solution, once every 7-10 days, for 2-3 consecutive times.
2. Cabbage downy mildew. Control measures: before sowing, dress seeds with 50% thiram wettable powder or 75% chlorothalonil wettable powder at 0.4% of the seed weight. Rotate with non-cruciferous crops for 3 years, and prevent proximity to cruciferous crops. The seedbed should be well ventilated and well lit, and low wet land should not be used as a seedbed. Combined with thinning, remove diseased leaves and pull out diseased plants. For low wet land, use high-ridge cultivation and rational irrigation and fertilization. After harvest, clean the garden and plow deeply.
Cabbage has a relatively long planting time, and it can be planted from late spring to late summer. When planting, you should choose the variety you need. In the later stage of planting, fertilizer and water techniques need to be done well, and cabbage is also relatively prone to pest invasion, so pest control work must also be done properly. Only by doing these well will cabbage grow better.
