How Israeli tomato cultivation
Israel is an agricultural power, we are growing greenhouse tomatoes, how they are grown? Some of them we can learn certain things. Suitable for greenhouse cultivation Israel large fruit tomato mainly Jiaqian Ya and gratifying other fine varieties. The variety is thermophilic vegetables, late-maturing varieties, unlimited growth type, growth period of up to 10 months, good facilities greenhouse growing up to 20 months or more. Height of 10 meters or more, usually in 70 to 80 days after planting to harvest, peel thick, very good storage, good taste, bright color, strong resistance, low temperature resistance, resistant to multiple diseases, is the scale of development , market-oriented varieties of vegetable production. Seedling nursery in open mid-August, using seedling raising. Nutrient preparation: Fertile Land six big plus 4 copies of composting manure, sift and mix per cubic meter of nutritive medium plus 50% carbendazim or Fenaminosulf 50 g mix, with a good spread in the seedbed, 12 cm thick. Qikuan 1.2 to 1.5 m, length. Seedbed before planting to be irrigated immediately after sowing under water seepage. 6 hours before sowing soaking, remove and mix with fine sand and then sow grasp about 100 per square meter, the seed planted three times, in order to ensure uniform seed (seedling raising one seed per pot). After sowing, spreading thin wet soil from 0.5 to 1 cm, then Gai Demo. When the seed thrown off most of the top soil mulch, often after spraying, keep the seedbed moist, water should be in the evening. When the 7-8 leaf height when planted in the greenhouse. Planting site preparation fertilization. Qiancha cleaned promptly after harvest, combined with plowing, decomposed manure applied per acre from 4000 to 5000 kg or 3000 kg manure, leveling rake thin; then press the major groove distance 90 cm, 60 cm away from the minor groove, Goushen 15 to 20 cm ditching, Summer DAP 40 kg per mu, potassium sulfate 30 kg, fugou ridging. Large ridge distance 90 cm, 60 cm away from the small ridge, ridge height of 20 centimeters. One with a double row of greenhouse drip irrigation equipment can be filled ditch between small ridge in the middle put a drip irrigation. Greenhouse disinfection. Koupeng after thoroughly disinfected once. Hot stuffy studio method can be used, the upcoming films seal, sunny hot stuffy studio 4 to 5 days sterilization, can also be used formalin 100 times spray disinfection. Colonization. Lifter irrigated before the seedbed to facilitate lifter. Lifter with soil as much as possible, each ridge planting two rows, spacing 40 cm, pouring enough water colonization. The next day after planting and then pouring a small water available, see the dry land shall be classified hoe cultivation. Huanmiao be covered with mulch. Pengwen preferably not more than 30 degrees. Huanmiao to live before the first spike fruit generally do not sit watering dressing, Dunmiao, lived after the first spike fruit sitting pouring water. Combination of water per acre punch nitrogen, phosphorus and potassium fertilizer 15 kg. With drip irrigation equipment, fertilizers can be integrated into the storage pool, with drip irrigation was applied. Management alone pruning seedling grows to 30 to 40 cm in time hanging vines. The first spike fruit base grow into fruit after the first spike lower @-T-all removed. The first spike fruit to stay four or so, leaving a second spike fruit fruit 5 to 8, with an average of about five fruits each subsequent spike fruit grown after all its lower leaves removed, in order to facilitate air and light, to prevent the occurrence of disease, there is conducive to fruit coloring. Management focus is to preserve Wen Zengguang winter, try to keep the temperature around 28 ℃ in the daytime, at night 10 ~ 15 ℃, while maintaining adequate light, grass thatch timely Uncovery, grass thatch can be re-covered with a layer of ordinary films, in order to facilitate heat , anti-rain and snow, big films should be promptly removed dirt and grass clippings, maintaining transparency. Winter and spring fertilizer management in winter - like watering as little as possible to prevent the temperature drops rapidly. The best storage of the greenhouse for some time relatively mild water, watering can with water applied per acre A fertilizer 15 kg. Into the end of February, early March, the temperature rose gradually, you can gradually increase the amount of fertilizer to increase the watering frequency, March 7 to 10 days after every watering 1, and applied a second compound, also in the leaf surface foliage spray with the active conduct of potash, while strengthening ventilation. When the plants grow to a roof fall when vine. Is these - strains every 1 to 2 to another sling hanging on the cross hanging vine in late April after the film to be set off in front of the greenhouse to prevent the temperature is too high incidence of weight. Pest control major diseases are leaf mold and gray mold, can be reduced by strengthening the management of greenhouse ventilation to prevent moisture. Early onset must promptly remove diseased leaves, removal of diseased fruits, with 75% chlorothalonil WP 600 times, or 50% procymidone WP 2000 times spraying.
