Provence is a large red-blooded tomato variety introduced by the dutch deutsche ag. An infinity growth model, with a strong plant growing at a high rate of not-for-nature, high yield, thick slices, fruit beauty, good colour, large fruit size, with an average of 200 to 300 grams of single fruit. Provence tomatoes are not faceless, empty, sweet, not sticky, the king of fruit tomatoes。
I. Introduction to tomato varieties in provence
Provence tomatoes are highly resistant to dysentery, yellow atrophy, tomato atrophy virus, etc., and are suitable for early springs, autumns, winters at large, or arch sheds at early springs and summers。
Ii. Timing of cultivation and market prospects
1 mid-september;
2 at mid-october
The harvest began in mid-january of the following year, with a market output of about 7000-10000 kg per acre, with a value of 4. 5-6,000 yuan。
Child breeding
1 seed selection
High-quality vegetable seedlings are cultivated with high purity, growth and growth rates. Provence. Seed treatment: 1 - 2min is being mixed in 60°c water, water temperature reduced to 30°c and 6 - 8h is immersed。
Two tremors
The seeding is sprung with a tremor box, the tomato is sprung with a 25°c of 36-48h per 6-8h seed, and when about 80% of the seed is sprung, the seed is sprouts are sprung if they are too long, and the seed sprouts are checked daily. With a 50-hole plate。
Iv. Shrimp management
1 temperature
Temperature drops to 20-23°c after 80% before seeding and 13-15°c at night。
2 water management
In order to keep the matrix dry and wet and clear the weather, water is normally sprayed every morning at 6-7:00, when local drying is done in the afternoon, and water is replenished. Water should be properly controlled during rainy days。
Three chassis alignment
In the event of an uneven growth of seedlings, the position of the lair should be adjusted in a timely manner to promote even growth of seedlings。
4 diseases
The main ills of the shrunk season are sudden-onset disease, standing sickness, frost, etc. Formula: 72 per cent of plick 20g plus cavity 3g and bio 20g to water 15kg spray。
5 seedling standard
When seedlings are produced, the seedlings are strong, the leaf colour is normal, the roots are well developed, disease-free, and they have their own species characteristics, with leaves of 8-10 or more。
V. Planting
1 deep across the soil
After harvests in the summer sheds, it is necessary to tumble early and deep in time for high-temperature storms to tan the tanning soil. It takes more than 40 centimetres to dump the ground no later than 20 days before planting. Rational rotation: two years or more with legumes, thorium, etc。
Two feet fat
Per acre farmers are 3000 kg fat or 2-gauge organic 40 kg fat and 100 kg high potassium per acre, plus 2 kg large pellets and 300 grams large zinc。
I'm going to have to put on a rag before i plant it
The selection of nuanced po-films can improve temperature, reduce humidity and increase ventilation and lighttime during the day, and can have a good disease control and prevention effect。
4 high-level planting
In combination with the soil acreage, it is usually not sticky, but the center of the cavity is 0. 3 m wide. 0. 15 m deep.
5 rational irrigation
The weather forecasts are heard before the water is poured, at least by the sun or by clouds without rain. The water will be watered before 10:30 a. M。
Post-plant management
Management before and during winter
One slow drop
Attention is paid to covering the shantytown film, which is 28-30°c during the day and 17-20°c at night, and which is not less than 20°c at night, in order to promote the seedlings. The temperature of the shed is reduced, as appropriate, after slowing down, 22-26°c during the day and 12-15°c at night. Sprayed 1 to 2 times to protect 3g plus biao 20g to prevent growing plants. Single-stamped, timely scrubbing and binding。
2 before and after the first chorus
In order to prevent low temperatures from causing drop-off fruit, 30 x 1/100,000 seedlings can be used. When the fruit sits, it is properly oozing and leaves three or four fruit per ear。
When the fruit of the first bouquet is walnut-sized, water is poured under the high pecan membrane, and bulges fertilizers can be applied to one third of 10 kg per acre, increasing the luminous rate of planting, balancing nutritional growth and reproductive growth; and in 15 to 20 days, the great red bull nutrient king (comparable acid, sequestered moderates, trace elements) is applied to produce 10 kg, promoting fruit growth. When the fruit enters the booming stage, high potassium is applied to fertilize (7-8-35) and 10-15 kg at a time, prompting the expansion and strength of the fruit to promote early preparation。
3. Temperature management after water and fatting
The water is used to increase the temperature of the interior, reaching 33°c in the morning, closing the vents at 25°c in the afternoon and controlling them at about 12°c in the morning, beginning ventilation the following day at 31°c, moving to normal management on the third day to water as much as possible and controlling water during winter。
4 temperature, light, etc. Management
It is timely to uncover the herbs and to extend the light as long as possible; it is also necessary in snowy weather to expose the plants to diffuse light. The temperature in the shed is 20-30°c during the day, 13-15°c during the night and the minimum night temperature is not less than 8°c. The skylight can be used for ventilation when the temperature reaches 30°c at noon。
5 co2 fertilization
During the winter, there is low temperature, low ventilation and a lack of use of organic fertilizers in the shed, which leads to a shortage of carbon dioxide. For this purpose, at 9-11 a. M., a suitable concentration (600-800) x 1/1,000,000 co2 fertilization can be performed。
The six fruits are in a changing phase and are collected in a timely manner according to market needs。
2. Post-winter management
1 temperature, light management
After mid-february, the number of sun-lighted hours has gradually increased, with appropriate early exposures and late-bursting of grass, with the aim of increasing the light of the plant as much as possible. Take care to clean the laminates and increase the light coming in. Care is taken to provide timely ventilation, in the middle of the day, at 25-28°c, 25-20°c, 15-20°c in the middle of the night and 13-15°c in the middle of the night. In the rainy days, the day is 25-20°c and 10-15°c at night。
2 fat water management
Between mid-february and mid-march, the application of fertilizers can be applied by one to three tenth kg for each of 667 m2, increasing the rate of luminous and reproductive growth by increasing the ratio of plant luminous growth; and 7-10d (days) the application of fertilizer b, the nutrient king (accumulation acid, sequester, trace elements) to promote fruit growth by 10 kg. When the fruit enters the booming stage, high potassium is applied to fertilize (7-8-35) and 10-15 kg at a time, prompting the expansion and strength of the fruit to promote early preparation. Or application of nitrogen, phosphorus, potassium compound fat 15 kg. After mid-march, one water watered, 15-20 kg ammonium phosphate applied, 5-8 days, and 3kg fertilisation applied by digah. (perhaps fertilizer is used interchangeably)
Three whole
• the timely cleaning of the branches, the plastering of the chickens, the protection of the chickens and the timely removal of the old, yellow and sick leaves and the improvement of the ventilation and light conditions. It was usually in late may and early june。
4 pest management
Phrases such as cracking, antxian, bacillus, dyson manganese zinc are regularly sprayed to combat folic disease, asymptomosis, early and late disease, timely spraying to combat pests, and pesticides may contain 20 g of babio, potassium phosphate (0. 2 per cent) or other folates. Insecticide spraying will not be available until five days。
Tomato major pest control
(a) grey silt: 65 per cent of the acreage is used to prevent the application of 45 kgg spray to water ... 2-3 times in a period of 7-10 days; the acre is used in kaiser 48g plus acupuncture 12g and the water 60 kg is sprayed four days in a period of 2-3 times
Night disease: 75 g of anacre-to-water 45kg spray... 7-10 days, 2-3 consecutive times; more severe occurrence; and 75 g of acre-to-water 45kg spray, 2-3 consecutive times in 4 days。
(a) virus disease: acre with 45mlning ncp plus 75% suspended zinc 15g spraying of water 45kg ... Every 7-10 days。
White lice: stop 60g of water for 45kg spray every six days。
The anti-disease agent is used in combination with folate fertilizer, saving labour, energy, disease prevention and increased production. Note: if the formulation above is mixed with the disease, it is recommended to be mixed with other pesticides。
