Planting technique of eggplant in greenhouse

Eggplant is a common vegetable in daily life, not only can be cooked, but also can do barbecue, very popular with people, the most important is the price is very close to the people, so the planting prospect is still good, what are the greenhouse eggplant planting techniques?

1. Land selection and preparation

Greenhouse planting land is generally relatively flat, which is convenient for greenhouse construction and later planting management. After selecting the planting site, it is necessary to integrate the topography of the planting land and the growth habits of eggplant for land improvement and consolidation, flatten the planting land and fine the soil, then apply enough fertilizer and open a ditch to make a flat bed about two meters wide.

2. Seed selection and seed treatment

The treatment of the seeds is usually in the following ways: one is to dry the seeds and bask in the sun for one or two days; the second is disinfection, usually soaking the seeds in 0.100 trisodium phosphate or 0.001 potassium permanganate solution for 10 minutes and 20 minutes; the third is to soak the seeds in a warm soup of 50-55 ℃, and then fish them out to dry after the water temperature reaches 30 ℃; the fourth is to accelerate germination and seal the seeds in a 25-inch 30-℃ environment to accelerate germination, which can be properly replenished with moisture. When the seeds above 2 + 3 produce root buds, they can be sown.

3. Sowing seeds

The main results are as follows: (1) sowing time: eggplant was sown in greenhouse from mid-July to the end of August, usually from early October to early November, and from December to June and July of the second year. Or according to the local actual situation, choose the appropriate time to plant.

(2) sowing method: when sowing eggplant, the seedbed should be fully filled with water, and the soil layer of 10 cm should usually be drenched. When all the water seeps into the soil layer, sprinkle a layer of 1cm nutritious soil, then sow seeds, and then cover 1cm of nutritious soil. In addition, fine soil mixed with 2 grams of Luheng No. 1 wettable powder should be sprinkled on a 1 square meter seedbed.

4. Management technology after sowing.

(1) temperature control: when sowing eggplant, the ground temperature should be controlled at 14-16 ℃. After the eggplant seedlings were divided, the temperature was controlled around 30 ℃ in the daytime and 24 ℃ in the evening. After the eggplant seedlings were slowed down, the temperature was controlled around 24 ℃ in the daytime and 16 ℃ in the evening. During the period of low temperature seedling refining, the temperature was no more than 20 ℃ in daytime, less than 15 ℃ at night, and 10: 12 ℃.

(2) Fertilizer and water control: it is necessary to carefully observe the growth status of eggplant seedlings, combined with seedling color and growth status to manage water and fertilizer. The seedling color is normal, the growth is exuberant, does not apply fertilizer; the seedling color becomes lighter, the growth slows down, then needs the additional fertilization. During the period of eggplant breeding, it is not necessary to irrigate too much water, and the soil of the seedling bed is not dry.

5. Transplanting and planting

(1) preliminary preparatory work: land leveling and fertilization are usually carried out first. 150 tons of farm manure and 850-1000 kg of compound fertilizer are applied to 1 hectare of land. Ridging is carried out after leveling. Then the greenhouse was built two weeks before the eggplant was planted, and the temperature in the greenhouse was raised to keep the soil temperature 10 centimeters deep at 10: 12 ℃.

(2) planting method: when planting eggplant, choose sunny morning planting. First dig holes in the high ridge, and then water, when the water is about to seep out, put in the eggplant seedlings with soil, then seal the soil and fix it, then cover the film. Pay attention to digging holes, leak eggplant seedlings out of the film, and then cover the film holes with soil. The plant spacing of eggplant seedlings should usually be kept at 40 cm, and the row-to-row spacing should be 50 cm. 3500 eggplant seedlings should be planted per mu.
