So, do you know how many days Chinese cabbage grows? What are the planting time and methods of Chinese cabbage? Let's have a look.

How long is the growth period of Chinese cabbage? About 1 55 days left. The growth period of Chinese cabbage is relatively short, generally about 55 days. Different regions and climatic environments will affect the growth period of Chinese cabbage. Chinese cabbage likes to grow in a cold climate, usually planted in August-September, and harvested after 10 months.

2. When Chinese cabbage is properly watered during the growth period, it is most beneficial to the vigorous growth of Chinese cabbage to water it reasonably and keep the soil slightly wet. Every time watering, the amount of water should be large and even, and the water should be properly controlled in the later growth stage of Chinese cabbage to promote its core-wrapping.

3. Timely topdressing Chinese cabbage needs timely topdressing during the growth period. It is necessary to apply compound fertilizer rich in phosphorus, potassium and nitrogen during the heading stage and heading treatment, and to spray foliar fertilizer every 7- 10 days for 2-3 times at a time. Pay attention to stop fertilizing 20 days before harvesting Chinese cabbage.

4. Pest control During the growth period of Chinese cabbage, attention should be paid to the prevention and control of pests and diseases. Yellow sticky boards can be placed around Chinese cabbage to trap and kill aphids, whiteflies and other pests. If the pests and diseases are serious, it is necessary to spray fungicides and pesticides on Chinese cabbage in time to make Chinese cabbage grow healthily.

Chinese cabbage planting time Chinese cabbage is mainly planted in autumn. According to its varieties, the sowing time can be divided into: early-maturing varieties are sown in early and middle August, middle and late-maturing varieties are sown in late August to early September, and late-maturing varieties are most suitable for sowing in late August.

Chinese cabbage planting method 1, soil preparation and base fertilizer can be planted in the north and south, so it has low soil requirements and can adapt to various environments, but sandy loam or loam rich in organic matter is the best, and the previous crops in the selected plot should not be cruciferous, so the rotation should be reasonable.

Soil preparation and fertilization should be carried out one week before sowing, and the plots should be deeply plowed and raked, and the ridges should be leveled and ditched to facilitate irrigation and drainage.

Apply 5000-7000 kg of decomposed organic fertilizer per mu, and at the same time mix 50 kg of NPK compound fertilizer and spread it evenly on the soil. Combined with cultivated land, the fertilizer and soil are mixed evenly.

2. Select excellent seeds with strong stress resistance, cold resistance and no disease to sow and raise seedlings. There are three ways to sow, namely, drill sowing, hole sowing and machine sowing. Choose a suitable sowing method for sowing, and the general dosage is about 0.5kg per mu.

When sowing, control the row spacing of plants. If the climate and soil conditions are good, it can be planted densely, otherwise it should be planted thinly.

After the seeds germinate, keep the soil moist and accelerate the emergence of seedlings. When 2-3 or 4-5 real leaves are grown, the seedlings should be replanted once every other seedling, and some weeds, diseased seedlings and weak seedlings should be removed.

3. Planting When the seedlings grow to 5-6 true leaves, they can be transplanted and planted. Choose sunny afternoon when transplanting, try to avoid the strong sunshine at noon, and increase the survival rate.

It is also necessary to determine the density according to the variety and soil, water it immediately after transplanting to keep the soil moist, and then water it once every morning and evening for three days to help slow down the seedlings and keep them alive.

4. The yield of field management Chinese cabbage is extremely high, so the amount of fertilizer needed is also extremely high. When preparing soil, we should not only apply sufficient base fertilizer, but also timely topdressing. Generally, after applying sufficient base fertilizer at seedling stage, topdressing is not needed. If there is not enough base fertilizer, ammonium sulfate can be topdressing 65,438+00 kg per mu, and it should be sprinkled on both sides of the seedlings when fertilizing, so as not to directly apply the root system to avoid burning the root system. Water immediately after fertilization can make fertilizer.

After transplanting, topdressing fertilizer for the second time, at the same time topdressing ammonium sulfate15-20kg, ditching and watering; For the third time, 30 kg of ammonium sulfate and 15 kg of calcium superphosphate were applied at the stage of tree cluster, combined with soil cultivation; For the fourth time, ammonium sulfate 15-20 kg was applied at the nodulation stage.

Watering is also very important, depending on the climate and soil. Water should be controlled at the end of the rosette and watered after the third topdressing. Chinese cabbage needs a lot of water when heading, so the soil should always be moist.
