Tomato field cultivation (vegetable seeds)
I. Selection of varieties
The selection of disease-resistant, high-quality, productive, durable, commodity-friendly and market-friendly varieties. Spring and summer
Low-temperature light, fast-growing early and medium-sprincipal varieties of fruit, selected antiviral diseases and heat resistance in the summer and autumn winters
Medium and late ripening。
Ii. Cultivation
1. Preparation for seeding。
(1) nursery facilities. Daylight greenhouses, plastic sheds, chains, depending on season, weather conditions
Feeding facilities such as greenhouses, sunshields, hotbeds and summer and autumn nurseries should also be equipped with insecticide-proofing, sun-shielding facilities, with conditions
Creasing and plant-based seedlings could be used, and nursery facilities could be sterilized to create suitable seedlings mio! Fan
(c) long developmental environmental conditions。
(2) nutritional soil. (c) the selection of soil, decomposed farmers, herbs, ash
Composite fertilizers, etc., trophic soil as prescribed, pore depth of approximately 60%, ph6-7, quick effect phosphorus 100 mg/
More than kg, potassium velocity 100 mg/kg, nitrogen velocity 150 mg/kg, laxation, fertilizer protection
Water, full nutrition. The prepared trophic soil is spread evenly in the seeding bed, 10 cm thick。
(3) seed beds. Adequate seeding beds are prepared in accordance with the planting plan. Forma per square metre
30-50 ml with water, 3 litres with sprayed bed soil, 3 days with plastic membrane to cover and smell. Break
Scroll it back。
Seed treatment。
(1) sterilization. Hot soup soaks. Put the seeds in hot water at 55°c and keep the water evenly immersed at 15%
Bell. The main causes of this disease are foetal disease, ulcer disease and early disease. Three sodium phosphate leachate. It's been three or four hours since i was immersed in water
A further 20 minutes of immersion in 10 per cent of the sodium phosphate solution is released for cleaning. The main fight against viral diseases。
(2) leaching seedlings. The sterilised seed is immersed in six to eight hours and purified at 25°c
Wet-spruce。
Seeding。
(1) sowing period. Select suitable broadcasts based on planting seasons, climatic conditions, nursery methods and growth indicators
Casting period。
(2) sowing. Usually 20-30 grams per acre, 10-15 grams per square metre seedbed

Grams。
(3) the method of sowing. Seeds can be sowed when over 70% of seed seed is lumbered
Post-seed planting. Before seeding, water pours down the bottom, and when it leaks, it spreads out a layer of nutrients, looking for a flat bed
Seeding. It's about 0. 8 to 1. 0 cm. An additional 8 grams of more than 50% of the fungus moisture per square metre of seed beds
The powder is mixed with thin ground on the bed floor to prevent sudden disease. Winter spring bed covers the membrane, summer and autumn
The bed covers the sunnet or straw and 70 per cent of the plumes are removed。
4. Shrimp management。
(1) environmental regulation. Summer and autumn seedlings are mainly cooled by sunshields, and the temperature management of winter seedlings is shown in table 1。
Table 1 temperature management indicator for the moist season
Time temperature °c night temperature °c
The minimum night temperature is not less than
I'm going to plant it 25-3018-1513 before it comes out
20-2515-108 before the drop
Saplings 25-3020-1510
It's 20 to 2515 to 108 before planting
Five to seven days, 15 to 85 days prior to planting
In winter, seedlings use light measures such as mirrors, and summer and autumn seedlings adequately cover the cooling。
Saplings are to be filled with sufficient water, which is to be applied in the light of the nursery season and subsequent periods. I'm gonna spray 1000 times more than i've ever seen
Clear or 500 times manganese zinc。
(2) saplings. The seedlings are grown in a nursery and placed in a nursery at the time of the two leaves。
(3) expansion of nutritional area. Increased sapling spacing at three to four leafs, with thin mud or poaching of containers
Ash filled, humid。
(4) fertilized water management after seeding. The nursery season is dominated by water and fertilizer control. When it's three to four leaves, it's combined
Following the fatting of the seedlings。
(5) refinery. Early spring breeding 15-20°c, night 10-5°c. The summer and autumn seedlings gradually retreat to cover the sun
Net, properly control the moisture。
(6) shrimp indicator. Cultivated in spring and summer, 25 centimetres tall, thicker than 0. 6 centimetres
Ray. Cultivated seedlings in the summer and autumn winters, four leaves, 1 centimetres high, 15 centimetres thick, 25 centimetres thick

It's born in heaven. Leaves are green, disease-free。
Iii. Planting
1. Pre-plant preparation. Whole area application of base fertilizers, general base fertilizers: phosphorus fertilizers are 80% of total fertilization
On top, nitrogen and potassium fertilizer account for between 50 and 60 per cent of total fertilizer application. Quality organic fertilizer of 3,000 to 4,000 kg per acre
Fertilizer supplements when nutrient content is insufficient. Organic fertiliser spreads, tumbling 25-30 centimetres deep. According to local planting habits
Do the platinum。
2. Timing. Spring and summer cultivation is stabilized at 10 cm and above 10°c。
3. Plantation methods and density. Use size lines to plant, cover the membrane. Depending on the nature of the species, the method of the branch
Long-term, 3,000 to 4,000。
Iv. Field management
1. Fertilizer water management. Undercover dripping or dark irrigation. After planting, water was poured in time, and three to five days later, water was poured out
Then, when the first fruit sits firmly, it begins to water and fatten. Soil moisture in the outcome period
It is appropriate to maintain a range of 60 to 80 per cent of the maximum soil water available. Based on soil fertility, plant fertility season and
Growing conditions catch fat in time. Fertilizers for conventional cultivation are shown in table 2 and, after deduction of the base fertilizer component, are pursued with water on several occasions
In areas where soil trace elements are lacking, the variety and number of fat pursuits should also be increased for deficiency。

High fertility 4,400-540015-183-69-12
2. Plantation adjustment。
(1) stamps, chicken binding. With a pole and a chicken in time。
(2) the whole method. The whole branch of tomatoes consists of one and a half pole and two and three
Methods, selection of appropriate whole branch methods based on planting density and purpose。
(3) cardio, leaf. When the top one blooms, leave two leaves to hold on to it
The side branch. Remove the yellow and sick leaves in time。

3. Porridge berries。
(1) pocket. During the season when tomato sits fruit is not suitable, plants such as anti-depressants, tomatoes and so forth are grown
Stimulant treatment of plume. In areas with a high incidence of asymptomatic diseases, pharmaceutical preparations such as coromoli should be added to the solution. In production
2,4-d。
(2) the fruit. With the exception of cherry tomatoes, the product should be properly qualityd, with fruit-type varieties per ear
Three to four fruit types; four to six fruit types per ear。
Collection. Timely harvests in batches to reduce the burden of planting to ensure the quality of commodities and promote later effects
The summer and autumn cultivation must be finished before the frost。
V. Pest management
1. Catastrophe, death. Except for the sapling of the bed. It's also possible to use frosting + dyson manganese zinc, frosting, etc
Drug control。
2. Ashy disease. Controlled with agents such as cormory, sulfur, vinyl fungi nuclear agent, vulcan。
3. Early disease. Use of agents such as dyson manganese zinc, bacillus, chronin + copper hydroxide and mercuric manganese zinc prevention
Oh, shit。
4. Night disease. Controlled with acetphosphorous manganese zinc, frosting + dyson manganese zinc and frosting。
5. Yelp. Treatment is carried out with a combination of musculin, chronin + copper oxide and bordeaux。
6. Erosion. Controlled with such agents as copper hydroxide, bordeaux and agro-chainicillin。
7. Virus disease. • controlled with drugs such as hydrochloric acids, copper and 83 amplifiers。
8. Aphids, white lice. Controlled with a combination of bromocythrin, liquefine, amphibians and benzothrin。
9. Leaf flies. It is treated with dictums and poisons。
Strict control of pesticide usage and safety intervals is shown in table 3。
