Fruit Cucumber Greenhouse Cultivation Technique

First, nursery

1. Nursery time

According to the reproductive characteristics of fruit cucumber and the local actual conditions, the nursery time is more appropriate in the middle and late February.

Seedbed

Sawdust and coal residue are optional as a filler for the seedbed. The selected filler is sieved, an appropriate amount of water is added, and the virus is removed at a temperature of 100° C., and the water is removed after 10 minutes. The moisture content of the filler can be 60% to 70%, and then the filler is evenly spread on the seedbed with a thickness of 20-25 cm.

3. Sowing

Nursery indoor seedbed temperature at 25 ~ 30 °C when sowing, the seed evenly withdrawn on the seedbed, covering 1-2 cm thick sandy loam soil, covered with film to maintain humidity. After sowing, the room temperature is always maintained at about 30°C.

4. Transplanting

1 Preparation of nutritious soil The formulation of nutrient soil is more, depending on the conditions, the principle is to ensure that nutritious soil has a certain fertility, loose soil, and good ventilation. Select soil with fertile soil and garden soil that has not been planted with melon, sieve, add fermented farmyard manure, and the ratio of manure to soil is 4:6. If fertility is insufficient, nitrogen fertilizer can be accelerated, and 0.5 fertilizer per cubic meter of soil is added. Kilograms of urea should not be used to prevent burning of roots, urea and nutrient soil. To control seedling diseases, fungicides can be added to the nutrient soil. When the humidity of the nutrient soil reaches about 60%, it is piled up, covered with a film, and kept for 2 to 3 days.

2 Packing Choose a plastic bowl or paper bag with a diameter of 5 to 7 cm and a height of 10 cm and put it into a prepared nutrient soil.

3 Seedlings can be emerged about 7 days after sowing, and the film is lifted after emergence. When the first true leaves appear to flatten out, they can be transplanted into the nutrition bag. The temperature in the shed is always kept above 28°C after transplanting, but It must not exceed 35°C and it must not be lower than 15°C at night.

Second, planting

Before planting, the land was turned over. According to the specific conditions, 267 square meters of greenhouse sheds were applied with 2 to 3 tons of phytofertilizer and 40 to 50 kg of superphosphate, and then turned to the ground. The width of the plant is 1.3 meters. Each plant is planted in two rows with a spacing of 40 to 50 centimeters and a plant spacing of 20 to 25 centimeters. Before March 20th, it is necessary to dig a hole to plant a plant. At this time, the melon seedling has reached 6 to 7 true leaves.

Third, fertilizer and water management

When the seedlings are poured, the seedling water will be poured once; when the seedlings begin to reduce seedlings, the water should be poured again for 1 time. After this, watering was suspended, and cultivators were used several times to reduce the evaporation of water and promote seedlings to grow roots and grow strong. When the root melons grow thicker and longer, watering is resumed. With the gradual warming of the weather, the amount of water can be gradually increased to meet the needs of the growth and development of fruit cucumber. At the same time, the combination of watering for fertilization, watering and fertilization should be alternated, farmyard manure and chemical fertilizers used interchangeably. In the early stage, the top-dressing fertilizer is preferably farmyard fertilizer; after the melon period, more fertilizer can be applied, and 267 square meters of greenhouse can be applied with 5 to 10 kg of urea each time.

Fourth, branch management

When the cucumber seedlings have about 7 leaves, the plants are easy to fall down, and it is necessary to insert racks or slings. The slings are more convenient. First, iron wires are tied on the posts at both ends of the shed to make the wire tight. Then, the slings are put on the wires, and each sling is one. Then tie the vines, according to the situation once a week. If there are side vines, leave 1 melon on the side vines and leave one on the melon topping. In the later stage of childbirth, the old yellow leaves in the lower part of the plant are removed to facilitate ventilation and light reduction and reduce disease.

V. Harvesting

Root melon can be harvested earlier as long as it meets the needs of the market. Early harvest of root melon can promote the growth and development of the remaining melon. With the expansion of nutrient volume, the melons in the middle have more nutrient supply and accelerate the growth rate. At this time, the harvesting interval is relatively shortened, and one to two days can be harvested. Harvesting should be carried out in the morning to keep it fresh and tender.

VI. Disease Prevention

The diseases of fruit cucumber are mainly downy mildew and powdery mildew, spraying and sterilizing pesticides 7 days after planting, and spraying 3 times for prevention.

Joist Tape

Joist Tape Deck Flashing Tape Butyl Joist Tape for Decking

The Joist Tape is a malleable polyethylene waterproof wood flashing and material, using a rubberized asphalt mastic adhesive. Rot is caused by moisture that stays in contact with treated and untreated lumber deck framing and the above decking material. Wood decay can also occur when deck screws penetrate the deck boards, piercing the joist sub-framing below. The deck joist tape is easily apply to decking joists, around deck support posts and over ledger boards, which creates a waterproof seal that helps stop decay and wood rot.

The joist tape for decking as a barrier, it can reduce moisture damage to crossbeams. The joist butyl tape is used in temperatures range of -20°F to 176°F, it protects and maximizes the life of your new deck and creates a waterproof membrane that prevents wood rot caused by moisture.

How To Use The Joist Tape for Decking

The joist tape for decking is easy to install just in seconds. Clean the adherend surface, cut the appropriate length as needed, peel off the protected film, and carefully press the tape against target area. Mistakes are easily rectified within the first few minutes of installation.
