Tomato cultivation techniques are a constant concern of many farmers ' friends, who can improve the fruit ratio of tomatoes by improving the management of tomatoes。
The technique of growing tomatoes in the shed is based on a small-sized, high-spectrum system of 70-80 centimetres, 40 centimetres and 10-15 centimetres, two rows per millimetre, determined density at mid-morning and evening varieties and strains, usually 35 centimetres and 3,500 per acre. The range of pre-maturized varieties is 25-27 cm, with approximately 4,500 plants per acre. The membrane is fixed and water is poured in due course at 0. 5-1 kg per den. The same can be done with cucumbers, with two small cucumbers on the side。
The bottom fertilizing of the technology used to grow the garb tomatoes requires that organic fertilizers be fully decomposed. When a pie is used, a bean pie can be smashed into a brick size, immersed in the cask for a few days, finely treated with its hands for acidic acid, foams in the cask, fermentation and a gun in the back nest, 0. 4-0. 5 kg each. In the case of corrosive fats, they can be enclosed at the start of the acre, either by adding ammonium phosphate or compound fertilizers at the start of the acre or plant, 20-30 kg/acre. If diammonium phosphate or compound fertilizer is applied in the cave, it should be distributed with pie fat and fully mixed with the soil in the den to avoid root burning。
The management of the fruitful period of the technology for tomato cultivation in the shed, temperature 25 - 28°c, temperature 24 - 25°c, with due regard to the proper timing of the vent; suitable soil with a water content of 20 - 25 per cent, with water being poured once for 10 - 15 days; high-yielding sheds or nitrogen-deficient sheds can also be used to spray cicin (9220) to promote strong plants, thick leaves, and 7 - 10 days. At least four to five doses of urine per gram of cactinin 200 pounds per water; pre-water spray spray and pre-water fumes and dust-free fumes; sick leaves are collected in time for ripe fruit; and various alternate applications are used to seriously combat pests and diseases. The focus is on early disease, late disease, grey disease, viral disease, pink lice and aphids. The selection of 2,000-3000 ppm ethylene immersion to be taken out, placed at 22-25°c, properly ventilated, after 5-6 days, then red, and, if not red, not red, better quality。
The above is the technology for the cultivation of tomatoes in the shed, and farmers ' friends should strengthen the management of tomato crops in a timely manner, which can increase the fruit ratio of tomatoes and increase yields。
