1. Select the appropriate species According to the climate characteristics, the market needs to choose the unlimited growth, low-temperature resistant, low light, hard fruit type, storage and transportation of Israel's Heisela company cultivated FA-189 varieties.
2. Proper nursery nursery time is determined according to the variety characteristics, market demand, etc., generally between July 15-25, seedling age master 25-30 days.
3. The scientific seedlings are nursed with seedlings and seedlings, and the seedlings produced by the Soil Fertilizer Institute of Shandong Academy of Agricultural Sciences and produced by Qingdao Lvyuan New Technology Co., Ltd. are used. Seeds are soaked with fresh water for 3-4 hours before seedlings, then soaked in 10% trisodium phosphate solution, then soaked in fresh water for 3-4 hours. After sowing, cover soil 1 cm, and cover it with an old newspaper. Paul. Seedlings grow to 25-30 days, plant height 15-20 cm, stem 0.5 cm thick, 3-4 true leaf colonization.
4. Soil preparation before planting Before planting, crops were harvested and timely shed. The soil organic matter in the village was determined to be 1.5%-l.8%, available nitrogen 65 mg/kg, available phosphorus 10.5 mg/kg, and available potassium 160 mg. / Kg, according to the target output of 15,000-1.8 thousand kilograms per 667 square meters. The basic quality of basic quality fertilizer is 1 000 kg of high-quality fertilizer, 2 kg of dry chicken manure, 100 kg of ternary compound fertilizer (including N15%, P15% and K15%), 80 kg of urea, and 60 kg of potassium sulfate. Prepare a variety of high-quality fertilizers, spread them evenly on the ground and sterilize the insects on the ground, and then convert the ground to a large row of 80-100 cm and a small row of 40-60 cm furrows.
5. Settling and colonization time: determine the fixed time according to the nursery time, and the general colonization time is about mid-August.
Planting density: 2,000-2,200 plants per 667 square meters. After planting, the plants were sprayed with 500-fold solution of Primo 500 times and rooting agent to prevent seedling stage damping-off, root rot and other diseases, and promote root system. Grow.
6. Management after planting (1) Top-dressing watering When the first layer grows to the size of a walnut and the diameter is 4-5 cm, the water-fat joint attack is started, and the average one-third of the top dressing is watered once. Urea 8-10 kg, potassium sulfate 10 kg, a total of 8-10 times fertilizer, watered 8-10 cubic meters each winter. After spring, it is generally about 15 cubic meters.
(2) Pruning generally adopts single dry pruning. When the trunk of the sixth layer of the trunk shows flowering buds, two leaves are topped and topped. When the main fruit is harvested by 50% to 60%, it is decanted and the side branches are placed for second management. Generally top 2-3 times, a total of 20-24 layers.
(3) Decrease flower protection, increase fruit setting, and promote yield increase to prevent flowering and fruit drop. Generally, 30-50 mg/kg of anti-dropping agent is sprayed or 15–20 mg/kg of 2,4-D is sprayed and sprayed. Spend 50% of carbendazim or 50% of fast-inking to prevent botrytis at the time of flowering.
(4) After the disease prevention and control planting, the 7th day, spray 80% of Dasheng M-45 WP 500 times or 75% chlorothalonil wettable powder, spraying 25% of Amisidac at 10 days intervals. Wet powder 1500 times, spray once every 8 days, 80% Dasheng M-45 WP 500 times or 75% chlorothalonil wettable powder, then spray once every 7-10 days. Dasheng M-45 WP 500 Double liquid and pay attention to the prevention of virus disease at the seedling stage, can be used 0.5% anti-drug Feng Shui and other prevention, after the choice of drugs for different conditions. And in the prevention and control to master the "comprehensive prevention, prevention and control, rational use of drugs" principle.
Hou Wang Zhai Village, Houdian Village, Hebei Province, China Zhangwang Wang built a semi-underground large-thick-wall solar greenhouse (with an actual area of ​​8 meters and 50 meters) in 2002 and drove 50 farmers to build 60 greenhouses. Adopting the long-term wintering cultivation mode, applying the new high-efficiency cultivation technology, using rainwater harvesting and water-saving irrigation technology, the output of single sheds for the third consecutive year is 9,000 to 11,000 kilograms, which is equivalent to 15,000 to 18,000 kilograms per 667 square meters. Each shed has a water consumption of 180-220 cubic meters per production season (set on August 20 to June 30), achieving an annual efficiency of 10,000-1.5 million yuan per shed, and a profit of 2.1 per square meter. Million - 25,000 yuan (1.4 yuan per kilogram of tomatoes) The benefit per cubic meter of water is 70-80 yuan, and its main cultivation techniques are:
