Key points of pollution-free eggplant cultivation techniques

Varieties: mainly Nile, Britta, Langao and so on. It is an infinite growth type with vigorous growth, early maturity, long fruit, purple black, green handles, green pimple, no thorns, smooth and shiny texture. Single fruit weighs 300 grams-400 grams, and tastes good.

Nursery: soaking seeds to promote germination

Soak for 1 to 2 days before sowing, soak in warm water at 50 ° C to 55 ° C for 10 to 15 minutes, soak for 5 to 6 hours when the warm water drops to 30 ° C, and soak in 30% 1% formaldehyde After being washed with water, it is put into a gauze bag and germinated at 28 ° C-32 ° C.

Seeding: Seedlings are raised in the first half of August. Seeding * Seeds are selected from seedling trays and raised in the shed. If you want to raise seedlings, you should prepare a seedbed. Take 6 parts of field soil and 4 parts of rotten organic fertilizer, and then add 1kg / m3 soil of ternary compound fertilizer, and add 50% carbendazim 4 2 / m3 soil. Disinfection, the bed temperature is controlled at 25 ℃ -28 ℃ during the day and 16 ℃ -20 ℃ at night.

Seedling division: The seedling division is carried out in the three-leaf stage, with a row spacing of 13 cm to 15 cm, and a plant spacing of 10 cm.

Planting: Fertilization on the ground is generally 5,000 kilograms of rotten fertilized manure, 50 kilograms to 80 kilograms of ternary compound fertilizer, 2/3 application, 1/3 furrow application, ridge cultivation.

The suitable seedling size is 5-6 true leaves. The plant spacing is 50 cm, and the row spacing is 80 cm-100 cm. After planting, the temperature during the day should be controlled at 25 ℃ -30 ℃, and at night 16 ℃ -20 ℃, in order to slow down the seedlings.

Management: Results: The seedling pruning is managed in the early stage. The suitable temperature during the day is 26 ℃ -30 ℃, and the night temperature is 16 ℃ -20 ℃. Strong plants are grown. Compound fertilizer 15kg-20kg. Watering, hanging seedlings, double-rod pruning during flowering period are strictly prohibited, leaving 1 fruit per knot. In a timely manner, the tomato spot flower with a concentration of 50PPM.

Result Management during the heyday: pruning and pruning, shed temperature of 25 ° C-30 ° C during the day, 16 ° C-18 ° C at night, and a temperature difference between 10 ° C and 15 ° C at night and night are more appropriate. Water is poured once every 8-10 days, with 1 water interval, 14 times of topdressing, 10 kg of potassium sulfate and 15 kg of diamine phosphate per acre. Prevent long-term high humidity.

Pest control:

Gray mold is sprayed with 500% liquid of 75% chlorothalonil wettable powder, once every 7-10 days.

The cotton blight is sprayed with 800 times liquid of 72.2% pulex water or 600 times liquid of 80% mancozeb wettable powder, once every 7-10 days.

Verticillium wilt was irrigated with 350% of 50% copper succinate fertilizer (DT fungicide) wettable powder, and the roots were irrigated 0.3 to 0.5 kg three times per plant.

The tea yellow mite was sprayed with 3000% of 1.8% avermectin EC.

Aphids and planthoppers are sprayed with whitefly net or aktay 2000-3000 times liquid.
