High-efficiency Cultivation Technique of New Tomato Cultivars in Full-crown Greenhouse

1 Variety selection The full crown tomato is a hybrid new generation introduced from abroad. It is of infinite growth type, medium-early maturity, dark green color, stout stem, not easy to grow long, short in internodes, resistant to low temperature and low light, strong in resistance, fruit High round type, mature pink, no green shoulder, uniform size, the average weight of about 250 grams, the largest fruit up to 500 grams. Bright fruit color, no abnormal fruit and split fruit, thick peel, transport resistance, good taste, strong disease resistance, high resistance to leaf mold, virus disease, early and late blight, gray mold.

2 Cultivate strong seedlings and cultivate strong seedlings. First select the soil that has not been planted in the same crop within five or six years. The terrain is flat and relatively high. It can build nursery beds for irrigation, energy drainage, and well-ventilated plots. It is formulated with nutritious soil, organic fertilizer and soil. The ratio is 3:7, with 3 parts of high-quality organofertilizer decomposed by alcohol and appropriate amounts of nutrients in the nutrient soil nitrogen, phosphorus, potassium, calcium, magnesium five elements fertilizer, nutrient soil to prevent disease and insect repellent, seeds To soak the seeds with drugs, soak them in 100-fold potassium permanganate solution or 500-times formalin for 1 hour. Rinse the seeds with clean water and soak for 4 to 5 hours. Place the seed container until 25 to 30. The germination at °C, when more than half of the seed buds reveal white buds, they can be sown. After sowing, they must be protected from glare, high temperature, and rain hazards. Use plastic film, anti-yang net and insect net to make the seedling nursery bed temperature during the day. ~ 30 °C, 13 ~ 18 °C at night. Not less than 12 °C, to keep the soil moist, the air should be dry, prevent seedlings grow, planting 5 to 7 leaves per plant can be planted.

3 Colonization in the pre-planting shed should be fully applied to compost organic fertilizer and chicken manure, the five elements of nitrogen, phosphorus, potassium, calcium, magnesium and iron, zinc, copper, boron and other trace elements of compound fertilizer, but also to prevent disease Insect pesticides, deep plowing soil preparation, filling enough water, covering the shed film, high temperature dwelling shed for 7 days. After the shed, the temperature dropped to room temperature before planting, pay attention to weak seedlings, diseased seedlings, leggy seedlings removed when planting, use strong seedlings colonization.

4 field management, and pest control from the planting to the first spike inflorescence fruit size like a walnut, generally do not top-dressing, and control the water, control the drought without pouring, and ground cultivating loose soil, the length of an inflorescence fruit walnut size began to chase Once fat, each time the inflorescence of fruit size walnuts are top-dressed once, each time after the application of three elements of composite clothing 15 to 20 kg or urea 12 to 15 kg, top-dressing after watering, the shed within the daytime temperature 25 ~ 30 °C, 18 ~ 15 °C at night, not lower than 12 °C, plant the first inflorescence fruit set hanging rope to prevent lodging and timely prune fruit and vegetables, each fruit generally 3 to 4 spikes, up to 5, timely harvest, early prevention and control of pests and diseases, to be applied as soon as possible蚜虱 薰 薰 薰 净 薰 薰 薰 薰 薰 薰 薰 消 消 薰 薰 薰 薰 薰 薰 薰 薰 薰 消 薰 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消 消If there is a harmful fly, it can be used to prevent dichlorvos, because insects spread a variety of viral diseases, often timely investigation of the disease, to ensure a good harvest, for reference above.
