First, the variety of israeli tomatoes, r-143, is of an unlimited growth type, with fertility periods ranging from 6 to 10 months, with a capacity of 10 to 15 metres high, which is generally collected 70 to 80 days after planting, yielding 10,000 to 15,000 kg of 667 square metres and a maximum of 30,000 kg recorded in israel. An average of 120 to 180 grams of single fruit, green with a good storage capacity and a general shelf life of 20 to 30 days. There is good resistance to the tobacco leaf virus and it is suitable for protected cultivation in winter or early spring. B. Cultivation techniques 1. A balanced application of a full base of fattening and a balanced nutrient content is the basis of its high yield, with a balanced application of fertilisation, foot fertilisation, fully fertilized chicken dung of 6,000 kg ~ 8,000 kg, pie ~ 100 kg ~ 150 kg, ammonium phosphate of 50 kg ~ 75 kg, trigram fat of 75 kg ~ 100 kg, calcium perphosphate of 50 kg ~ 250 kg, borosa of 1 kg ~ 1. 5 kg, zinc sulfate of 1. 5 kg ~ 2 kg. All organic fertilizers, phosphorus fertilizers and two thirds of the fertilizer are distributed; all of the pie fats and one third of the fertilizer is applied in a gutter and concentrated fertilization is done. In order to maximize the growth of the root system, the r-142 tomato plant, which is large and well developed, creates a good root environment, requires a deep tweaking, 40 to 50 centimetres deep, smoothing, no light and no darkness, and then tweezing. The general size line is grown 100 cm wide and 15 cm high ~ 20 cm high; the small line is 50 cm wide as a course. Early spring planting is scheduled to take place in mid-december, with a suitable planting period of 20-30 february and a calendar age of about 70 days. The criteria for seedlings are 18 cm - 22 cm - 7 - 8 leafs. The first fragrance, the thickness of the leaves, the greenness of the leaves and the development of the roots. The plant is set at a distance of 35 to 40 centimetres, while 667 square metres are set at 2100 to 2,500. It is not appropriate to plant too deep, so that the soil is flatened and water covers the membrane. 3. Light temperature control (1) temperature control. At 25 °c ~ 30 °c, at temperatures of 25 °c ~ 28 °c during the day and 13 °c ~ 15 °c at night, to promote root growth. During the end period, the temperature begins at 23 °c - 25 °c, 26 °c and is closed at 20 °c; at night, 10 °c - 13 °c, with a minimum of 7 °c - 10 °c in the middle of the night and the following morning, in order to reduce respiratory consumption and to facilitate the transport of light matter. (2) light-ray regulation. It is important to increase the amount of light in management, to increase the amount of light that should be lifted early, even in the dark, and to increase the light in snow and rain. 4. Pump water is poured once in five to seven days after fat water has been established and will not be watered. When the first pecan is big, the second pecan is big, the third berries are flowering, they are followed by fertilizers, 667 m2 are applied with compound fertilizer of 10 kg to 15 kg, and 667 m2 are watered with 10m3 to 12m3. In the harsh winter season, water is duly extended, usually for 10 to 15 days, with the possibility of drip irrigation to save, heat, wet and reduce the disease. Composite fertilization can be applied with water at 10 kg per ear full. 5. Plantation adjustment (1) chicken whole branch. When a single pole is used, when the plant is 30 to 40 centimetres long, the chicken and the whole branch is emptied in a timely manner, and when the plant grows into the fruit, the underlying leaves and leaves can be removed from the bottom, so as to light up, mitigate the disease and reduce nutrient consumption. (2) precious fruit. The temperature is appropriate and the light is sufficient to enable the fragrance sequence to pollinate with less humidity, but when the temperature is low in the harsh winter or early spring and the light is weaker, the fruit of the flower must be protected. It is generally possible to use 10 mg/kg of 2. 4-d or 30 mg/kg of anti-depressants in order to beam fruit. And when flowers are stained, paint shall be added to it in order to prevent re-entry, and it shall not be spilled on the growth point or on the leaves, so as not to cause harm. After the fruit is delivered, the fruit must be delivered in time. 6. The market is open 50 to 60 days after the proper harvest usually takes place, and during the winter, when the colour part accounts for one half of the fruit, and when the spring part accounts for one third of the fruit, and when the spring temperature soars, the market consequences can grow and change. For early listing, ethylene-literate can be used, i. E. 40% of ethylene ethylene rims of 400-800 times more ethylene than during green ripening or chromatography, or sprayed with aerosols, 5-6 days early listing. Insects and pests can be treated with 500 - 600 times as much as venom, or 58 per cent more than 500 or 60 per cent of mercuric manganese zinc or 500 - 800 times as much as spray; tomato ash can be treated with 50 per cent more than 1,500 times poaching, or 1,500 - 2,000 times poaching, or 70 per cent more than 800 - 1,000 times as much as ketchup, or 60 per cent more than 600 times as anti-polypolythic micropowder, or with 20 per cent of the virus a500 times the fluid or 1. 5 per cent of an implanted fluid spray. In general, pre-incident spraying is used, with one spraying every five to seven days and three to four in the first stages. Better use of fumes or dust agents。
