When do leeks usually transplant? Can I grow it without soil?

Leek is a kind of vegetable that smells with a special taste, and consumers have different acceptance of it. Some like it very much, while others can't smell it. Leek is planted in all parts of our country, and its adaptability to the environment is very high. It is very suitable for lazy people to grow a kind of vegetable. When does the leek usually transplant? Can I grow it without soil?

First, when do leeks usually transplant?

Transplanting leek is a very critical step, the transplanting time of leek should be determined according to the growth of leek and the planting time of leek. Generally speaking, if the leek is planted in March and April in spring, when the leek grows to about 18 centimeters, there are four to five leek leaves, the growth is more exuberant, and the roots are stronger, then they can be transplanted.

If it is the leek planted in the early summer of that year, it is generally transplanted after two months of growth of the leek, and it is best to transplant after the rainy season to avoid transplanting to encounter the rainy season, resulting in the rotten roots of leek seedlings.

If leek is sown in autumn, transplanting is generally not recommended in that year, because the temperature is low when transplanting, the root of leek seedling is not easy to survive, and the time of leek seedling growth is low, the growth is not strong enough, so it is best to wait until the early spring of the next year for transplanting, the survival rate is higher at this time.

Before transplanting, it is best to pour water through the seedbed to avoid injuring the root of the leek. After the leek rises, prune the fibrous root of the leek root and retain the root about 5 cm. The leaves of the leek also need to be trimmed. Cut off the yellow leaves and rotten leaves, and keep the leek seedlings about 15 cm to avoid nutrient loss.

Second, can leek be planted without soil?

Chinese chives can be planted without soil. The specific planting methods are as follows:

First, the preparation of the cultivation device and the preparation of the culture medium. At present, the seed apparatus for soilless cultivation of leek is either customized to the factory or self-made. Self-made is very simple, buy 4-6 "thick foam board and plastic rectangular basin with good strength. The hole of foam can be punched by electrothermal punch, the pore diameter is 3 "4", and the row spacing is 18 × 12 ". The cultivation tank (basin) depends on the purchase of the finished product. The preparation of culture medium was as follows: urea 15 grams, potassium dihydrogen phosphate 22.5 grams, water 15 kilograms, pH 5.8-6.8.

Second, the selection and treatment of leek seedlings. The leek seedlings are dug, the soil is washed, and the senescent roots, residual roots and decayed leaves are cut off with scissors. 8 plants per kilo were placed in the round hole of the cultivated foam floating board, fixed with broken foam, and then placed on the culture medium. The water surface of the culture medium is just in contact with the leek root, or the water surface is about 1 inch lower than that of the leek root, and it is appropriate to let the leek root grow and extend into the culture medium to create an artificial adaptation process for the leek.

Third, the management of cultivation. After leek cultivation goes to bed, water is watered every other day, foliar fertilizer is sprayed every other day, and water and foliar fertilizer are sprayed alternately. Foliar fertilizer is sprayed with 1% urea and 0.2% potassium dihydrogen phosphate until the leek begins to grow. It can be watered and foliar fertilizer sprayed once a week in spring and autumn, twice in summer and twice in winter. In general, the culture medium should be added once a week without entering the root for 1-2 days. The optimum temperature for soilless cultivation of leek is between 15 and 25 ℃, which is suitable for planting in greenhouse or greenhouse. The light intensity is average, there is no direct light, there must be sufficient scattered light. In hot weather, keep the temperature below 25 ℃ and keep it ventilated and ventilated. At high temperature, it can be watered and sprayed to cool down to avoid leaf burns.
