Planting technique of celery in summer in greenhouse

Water celery is also wild celery, which often grows in places with water, such as water, ditches and fields. Water celery is a perennial plant with strong flavor and good taste, so it is deeply loved by people. At present, they are mainly wild vegetables distributed in Asia. But in fact, there are also artificial cultivation. Artificial cultivation makes use of the characteristics that water celery likes water and can grow in water, and begins the method of water culture in greenhouse. You can find out.

1. Greenhouse setting

Hot summer affects growth, so the greenhouse used in summer planting is actually a sunshade and cooling facility, mainly to cool down and make celery grow better. Select the planting field and build a greenhouse, which can be built directly in the paddy field. The fields are ploughed, fertilized and irrigated, and raked flat to make beds can be used for backup.

2. Planting

Summer can be planted twice, the first time directly picked the old plant, cut off the tender branches and leaves, the old stem directly cut into small segments, direct cutting, cutting distance of a few centimeters or so. After that, a new plant can be formed in about a month. It can be pulled and sold directly. Sow seeds for the second time, then sow seeds directly on the border, cover the straw, water and moisturize, and continue to breed after budding.

3. Greenhouse management

Requires the shading rate of 60% of the greenhouse film, not too high, seedling growth can not be photosynthesis, can not be too low shading effect is not good, or will affect the growth. It is usually necessary to spray water on the shed to cool down when the sun is at its greatest. A sunshade net should be built on the greenhouse. In general, the film should be opened for ventilation at night to avoid too much carbon dioxide.

4. Fertilization

After the base fertilizer, you can top fertilizer when there are 5 leaves, fertilizing 1000 jin of farm fermented manure per mu. No fattened poultry. Do not apply fertilizer to the leaves, the concentration of fertilizer is easy to burn the leaves. When fertilizing, remove some water, it is easy to absorb into the soil, two days later irrigation, to avoid too high concentration, and to maintain root water demand. In the future, observe the growth and continue to fertilize.

5. Irrigation

Water celery cultivation, mainly in the water environment, needs a clear source of water, sowing can keep dry and wet, easy to germinate, will not wash away the seeds. When the seeds sprout and the seedlings grow too long to wash away, the water layer of 5 cm can be maintained. When the growth height is more than 20 cm, the water depth can reach 15 cm. High temperature and deep water during the day, cooling at night can be cultured in shallow water.

The cultivation of water celery is mainly planted in water, and its growth is mainly managed by regulating water. Note that you can plant twice in summer, but in different ways. The greenhouse is mainly for sunshade planting and improving the planting environment, because the high temperature is bad for the growth of water celery.
