Cabbage is rarely heard of. In fact, cabbage is called kohlrabi in the Northeast. Let's take a look at the cabbage planting method and its technical points. We hope it will be helpful to you. 1. Cabbage seedling management

During the cabbage seedling cultivation process, it is not allowed to be treated for a long time. at low temperatures. When early cabbage has 3 leaves or late cabbage has 6 leaves and the stem diameter is 0.6cm, it will undergo vernalization when it encounters a low temperature of 12°C for 25-30 days, or a temperature below 9°C for 15 days, and early bolting will occur after planting. Phenomenon.

In addition, water control and cultivating of seedlings and seedlings can be appropriately controlled to promote root development; there must be no shortage of water in the seedling stage, and low-temperature exercise must be carried out during drought.

When producing in protected areas, it is necessary to increase ventilation, remove coverings such as plastic films or straw curtains, control the temperature at 13-15°C during the day, and control water. If you are raising seedlings in nutrient soil blocks (earthwork), you should cut and store the seedlings for low-temperature exercise. Such seedlings have strong resistance to stress and will slow down quickly after planting. 2. Watering method of cabbage

Cabbage should be watered in time after planting to increase the survival rate of seedlings. During the growth period, ditches should be cleared and drained to maintain good root development. Use Stem Strengthening Spirit in time to make the plant stems strong and the plants lush. At the same time, it can improve disaster resistance, reduce the amount of pesticides and fertilizers, and reduce residual poisons.

Do not let the air out after planting. Start letting the air out after slowing down the seedlings. Control the temperature in the small shed to 20-25℃, and let the air out when it exceeds 25℃. Do not water the outer leaves during the growth period, and increase ventilation. When the outside temperature has fully met the growth needs of cabbage, put it under a small shed.

When the leaves curl inward and begin to form balls, topdress with fertilizer and water, and apply 30kg of ammonium sulfate or ammonium bicarbonate per 666.7 square meters. After you start watering, keep the soil moist frequently. The harvesting period can be about 25 days earlier than that of open-field cabbage. 3. Short-term covered cultivation of cabbage in small arched sheds

Due to different harvest periods, the price of northern spring cabbage varies greatly. In recent years, short-term covered cultivation of cabbage in small arched sheds has been developed based on the early-maturing cultivation with plastic film covering. The planting period can be more than 20 days earlier than open field cultivation. The most popular variety is Zhonggan No. 8, with seedling age of 7-8 leaves. Apply agricultural fertilizer every 666.7 square meters/5000kg in the 2m wide border, plow deeply and level it, open 6 furrows, plant seedlings according to a spacing of 33-35cm between plants, fill with enough water for planting, seal the pot and insert a frame cover film. 4. Main pest control of cabbage

The main pests of cabbage are: diamondback moth, cabbage caterpillar and aphids. Diamondback moths eat the leaf bulbs and eat the leaves, and aphids suck the sap. For the control of cabbage caterpillar and diamondback moth, you can use 800 times solution of trichlorfon spray, or you can spray caterpillar fungus to control pests with bacteria.

To control aphids, you can spray 20% dimethoate emulsion 800 times.
