Tomato Cultivation Management in High Mountain Area

(Reference material)

(1) Cultivate strong seedlings of suitable age

The seedbed should be placed in a ventilated, high-lying place, and should be covered with plastic film and insect-proof nets to prevent rain and prevent the transmission of virus and pests. The nursery soil is mixed with 9 parts of aseptic garden soil and 1 part of enzyme bacterial fertilizer (Shaanxi Delong Bioactive Organic Fertilizer), put into a nutrient bowl or nutrient bag, and discharged into the seedbed.

 Generally, the seeds are sown from March 20th to April 5th (early). The seedlings can be soaked to accelerate germination before sowing. The seedling age is about 40 days. At this time, the seedlings have about 4-7 true leaves. Spraying 600 times of Dakenine once at the time of one leaf and one heart can effectively prevent most of the fungal diseases in the seedling stage.

Keep the soil moist and control the temperature at 25-28°C to prevent the growth of seedlings. Control water and refine seedlings 4-5 days before planting.

1-2 days before transplanting, spray Amicidal 1500 times solution to prevent dead seedlings after planting, and at the same time promote the healthy growth of seedlings, generally 1 kg of liquid/m2. 2-3 days before transplanting, spray the seedlings and seedbeds with Aktai 3000 times, 1-2 kg of liquid per square meter, which can reduce the harm of virus diseases and prevent whitefly, lasting for 20-30 days.

(2) Preparation before planting

Apply base fertilizer 10-15 days in advance, such as 4-8 cubic meters of decomposed organic fertilizer, 6-8 bags of enzyme bacterial fertilizer (Shaanxi Delong biological active organic fertilizer), and Yangfeng potassium sulfate compound fertilizer (N:P:K) =14:16:15) 50 kg, 25 kg potassium sulfate. After leveling and raking thin, spare. Flat or high border cultivation, one border and two rows, row spacing: small row spacing 60-70 cm, large row spacing 150 cm, planting 1800-2000 plants per acre.

Water once a day before planting to bring up the seedlings with soil piles. It should be carried out on a sunny afternoon or cloudy day to facilitate the slowing down of the seedlings. After opening the holes, pour the plantar water, and cover the soil for the planting seedlings to avoid burying the cotyledons. After planting, pour the furrow with sufficient water.

(3) Management after planting

Roots should be promoted after planting. Generally, do not water before slow seedling. Control the temperature at day temperature not exceeding 25℃ and night temperature 10-15℃. After flowering, control water and increase temperature appropriately, keep day temperature 25-28℃, night temperature 15-18℃, keep a temperature difference of about 10℃.

About half a month after planting, spray 700 times solution of Jinleydomir or Daconing to prevent Phytophthora root rot. Spray 1500 times solution of Amicidal at the first flowering stage to prevent leaf mold, early blight and other fungal diseases. After the first ear fruit is seated, it can be watered according to the soil conditions and used to flush with water. The fertilizer should be dissolved in advance before use. After watering, follow the principle of seeing dry and wet to prevent retting, and follow it after each harvest. Apply appropriate amount of fertilizer under water flushing. Do not flood with flooding, fertilizer topdressing should be done in small amounts and several times. During the high temperature period, ventilation and humidity reduction should be strengthened, and the upper part of the greenhouse can be covered with shading nets to cool down.

Single-pole or double-pole pruning is adopted, and the vines are suspended on a support. According to the situation, you can leave 6-7 ears and fruits, and leave 1-2 functional leaves on the top before topping. Timely remove excess side branches, old leaves, diseased leaves, etc.

(4) Fertilizer and water management

Water stimulating water: When the first ear fruit reaches the size of a walnut, choose to pour the stimulating water in time on a sunny day in the morning, combined with top dressing. Generally, 2-3 bottles of pure fungus Chong Shibao are flushed with water per acre, which can significantly increase the growth of new roots. The growth rate improves the absorption and utilization rate of fertilizers by plants. At the same time, in order to accelerate fruit expansion and increase the average fruit weight, you can add Yangfeng potassium sulfate compound fertilizer (N:P:K=14:16:15) 50 kg.

Fruiting period: As the fruiting period is entered, the nutrients required by the plants increase. Watering every 10 days, topdressing once every 15-20 days, and the second topdressing is mostly when the first ear fruit turns from green to white. Apply 30 kg of Yangfeng Potassium Sulfate Compound Fertilizer (N:P:K=14:16:15) per mu each time, 2-3 bottles of pure bacteria flushing Shibao or 10 kg of potassium sulfate, 10 kg of mixed sea champion, alternately Flushing, the effect is remarkable.

In order to prevent the senescence of the plant and promote the development and expansion of the fruit, the leaves should be sprayed with Tianmeibao, 0.3% KH2PO4 in the water and fertilizer management.
