Facilities

  Use of existing energy-saving solar greenhouse soilless cultivation, greenhouse soilless cultivation system installation, including the cultivation tank, irrigation facilities, growing media.

Select matrix

  The organic matrix of available corn stalks, mushroom compost, sawdust, sand or slag inorganic matrix is like. Available gangue, sawdust, corn stalks, the ratio of 1:2:2. 15 days before the use of the matrix stack 25 centimeters thick, wet the film to sterilization, then added two kilograms per square matrix organic soilless cultivation special fertilizer, 10 kg disinfect chicken, you can fill the slot after mixing. After the harvest of each crop matrix disinfected.

Soilless

  Choose low temperature, low light, high yield, disease-resistant varieties, soaking, most of the seeds can be sown after grin. Artificial soilless plug seedling method. By peat: vermiculite was 3: 1 ratio with a good base, per square meter of substrate was added 5 kg of chicken manure and disinfection 0 • 5 Gongjin vermiculite fertilizer, mix filled plastic disc 72 holes, each hole a tablets, overlying vermiculite 1 cm, separated by a plastic film and the soil under the plate. Pre-emergence temperature was maintained 25-30 ℃, after emergence temperature during the day 20-25 ℃, the night 10-15 ℃. Seedling tray should be kept moist, grow 3-4 true leaves to the pan colonization, about 30 days.

Colonization

  Leveling the matrix before planting to turn flat, about immersing cultivation tank, the matrix fully absorb water, water seepage pits every two slit Pa colonization, slightly higher than the matrix lump seedlings, plant spacing of 30 cm, planting 3000 acres, after transplanting pouring small water.

Cultivation and Management

  Fertilizer: 20 days after planting fertilizer, after fertilizer once every 10 days chasing, chasing each per plant soilless cultivation special fertilizer 10-15 grams of fruit seven days after chasing a fertilizer per 25 grams per plant, the fertilizer should be uniform sprinkle in 5 cm from the root, with the water to penetrate the matrix. It can also be applied in the shed carbon dioxide gas fertilizer. Usually pouring of water every five days after planting.

  Temperature and light: After planting, the daytime temperature 22-25 ℃, the night 10-15 ℃. After the fruit during the day and 25-28 ℃, night around 12 ℃, the winter season can be short Pengwen reach 30 ℃, but not through the winds. After winter, normal temperature management.

  Pruning: 6-7 when hanging vine leaves polypropylene plastic rope, rope wire portion is fixed to the scaffolding, in the lower part of the stem line. Vine intertwined with the sling, upright growth. Reserved only the main branch growth when pruning a result, the removal of all collateral within the leaf axils, 10-15 cm pruning side branches.

  Paul Flower and fruit thinning: 7-9 o'clock in the morning with a 10% -15% of the 2,4-D solution dip flowers, in order to improve fruit set. To ensure high quality fruit, fruit per plant to stay 3-4, the remaining fruit timely Thinning.

  Nutrition supply: According to me about the future of agriculture for many years summed up the experience in soilless culture, nutrient solution supply gap would be better, soilless tomato optimal interval about 15 minutes.
