Greenhouse celery planting management technology

[ Agricultural Products Network] Celery is rich in vitamins and mineral salts , and also has functions such as lowering blood pressure. Moreover, it has high output, good price, and can be produced on an annual basis. Farmers can get better economic benefits. Therefore, celery cultivation has attracted many farmers to choose. This article gives you a detailed introduction to the relevant technical knowledge of greenhouse celery cultivation for your reference.

First, the seedbed preparation

The seedbed should choose a gentle terrain without water, a relatively fertile sandy soil field, a seedling bed to grow 6-7 meters, a width of 1.2 meters, a depth of 10-15cm sorghum, each planting 1 mus of celery requires a seedbed area of ​​120? Leveling and applying insecticides to treat underground pests.

Second, soaking seeds

Soak the seeds in warm water at 15-20 °C for 24 hours, rinse gently with hands, rinse with 2-3 times to clean the sieved sand, and put them into a cloth bag or pot. Place at 15-20 °C. It is germinated in a cool environment, washed once a day with water during germination, and seeds can be sown after 3 days.

Third, sowing

Firstly, the seedbed is poured into the water. After the water seeps, a layer of fine sand with disease prevention and pest control is sprinkled, and then the seeds of the germination are mixed with the appropriate amount of fine gauze soil evenly spread on the seedbed, and then covered with a layer of 0.5 cm thick with sterilization. The fine sand of the insecticide, then use the old film to build a pergola around the seedbed, cover the straw curtain or shade net to avoid rain and direct sunlight.

Fourth, seedling management

After sowing, keep the bed soil moist. After the seedlings, flexibly grasp the small arch shed and covering with the temperature change, and timely carry out the seedlings 1-2 times, remove the weak seedlings, diseased seedlings, over-milk seedlings and weeds, and keep the seedling distance 2cm. It is advisable to colonize when the seedlings are as high as 8-10 cm and 5-6 leaves. In the seedling stage, insecticides and fungicides are sprayed once every 10 days to prevent seedling pests and diseases.

5. Soil preparation and fertilization

Combined with the ground preparation of 5,000-8,000 kilograms of deep-cut sorghum per mu of organic fertilizer , it is made into a hard sorghum with a width of 1 meter and a width of 20cm.

Sixth, colonization method

The seedling size is transplanted and transplanted for management. The planting density is 15-20cm and the plant spacing is 15cm. The planting of seedlings per acre is 3.5-400,000. The depth is based on the depth of the seedlings in the seedbed, and the roots are all stretched into the soil.

Seven, fertilizer management

Before the seedlings are kept, sufficient water is used to facilitate the slow seedlings. After the seedlings are slowed down, the fertilizers are chased once, and then the seedlings are cultivated. After about 10-15 days, the fertilizer and water management is carried out, and 800-1000 kilograms of manure is applied per acre to promote the rapid growth of celery. Topdressing once a day, moisture to keep the soil moist.
