[High Germination] Kohl Rabi Seed Kohlrabi Brassica Vegetable Seeds for Planting (200 seeds/pack) High Yield Organic Vegetables Seeds for Gardening Bonsai Seeds Fresh Vegetables Growing Seeds Easy To Grow Singapore Potted Live Plants for Sale Kohlrabi prefers mild, moist, and sufficient light. It is more cold-resistant and has the ability to adapt to high temperatures. The optimum temperature for growth is 15-30°C. During the expansion period of the fleshy stem, the flesh is prone to fibrosis in case of high temperature above 30°C. The choice of soil is not very strict, but it is suitable for planting in clay loam or sandy loam rich in humus. Planting time: Can be planted all year round, and use a small arched shed to raise seedlings when the temperature is low. Cultivation system: Generally, the flat-furrow seedling raising and intercropping system is adopted, and the seeds are sown in the ridges of the corn field, covered with soil after sowing, and thoroughly watered. Fertilization technology: Apply enough nitrogen fertilizer in the rosette stage of kohlrabi, and mainly use phosphorus and potassium fertilizer in the head stage. Reasonable irrigation: use sprinkler irrigation to replenish water, and water once every 3 days. 1. Selection of good varieties: choose excellent varieties of kohlrabi that are resistant to bolting and have oblate bulbs. 2. Timely sowing: Kohlrabi is generally raised on flat borders, and the suitable sowing period is from late January to early February. 3. Cultivation of strong seedlings: After the seedlings emerge, the soil should be raised once with a thickness of 0.5 cm to prevent the soil surface from cracking; after the cotyledons are unfolded, the distance between the seedlings is 6.7 cm, and the soil should be raised again after thinning, with a thickness of 0.5 cm to facilitate the seedlings to take root. , reduce the seedbed temperature. 4. Fertilizer and water management: In cultivation, it is required to start watering when the diameter of the bulb is more than 4 cm in the middle and late stages of expansion, and topdressing 1-2 times at the same time to promote the expansion of the bulb, and 15-20 kg of urea or compound fertilizer can be applied once per mu. 5. Pest control: The pests that harm Kohlrabi are mainly cabbage caterpillars, diamondback moths and aphids. Attention should be paid to early prevention and control, and 5% paraben, 10% imidacloprid and other pesticides can be used for control. 6. Harvest in time: Kohlrabi matures at the turn of July-August, the temperature is high, and the bulbs should be harvested in time, cut into filaments, sun-dried, and sold to pickles. Germination stage: The germination stage is from the time when the first pair of true leaves develops and forms a cross with the cotyledons. The length of the germination period is closely related to the temperature. The high temperature season in summer and autumn is about 10 to 15 days short, and it is about 25 to 30 days in winter and spring. Seedling stage: From the first pair of true leaves to the formation of about 5 to 7 leaves, and reaching a cluster, this is the seedling stage. The length of seedling stage is also closely related to temperature, about 15 to 20 days in summer and autumn, and 25 to 30 days in winter and spring. Rosette stage: When the second leaf ring to the third leaf ring is formed after colonization, the rosette stage is the time when 13 to 19 leaves appear until the beginning of the bulbing. This period varies according to the maturity of the variety and the number of outer leaves. It takes about 20-25 days for early-maturing varieties, 25-30 days for medium-maturing varieties, and 35-50 days for late-maturing varieties. Heading stage: from the inward curling of the heart leaves at the rosette stage to the harvesting of the leaf balls, this time is the heading stage, and the time required is also different depending on the maturity of the variety and the temperature. Generally, it matures early. It takes about 20 to 25 days for varieties, about 25 to 40 days for medium-ripening varieties, and generally more than 45 days for late-maturing varieties.
