"Tomato King" cultivation measures
"Tomato King" (cooperation 906) is easy to set fruit, high yield and resistant to transportation. The cultivation techniques are different from those of ordinary tomatoes. The key measures for cultivation are as follows:
First, reasonable determination of seeding time
For example, using greenhouses + small sheds + mulch + straw curtains for early maturity cultivation, seeding and seedling time should be selected from October to the beginning of November; use large and medium shed + mulching cultivation, should be from late November to December Seeding and seedlings in the middle.
Second, the fat bed is diluted, the nutrient 钵 钵 培育 培育 培育 培育 “ “ 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 「 When the seedlings grow to two leaves and one heart, they choose a sunny day to divide the seedlings, and it is too late to cause the flower bud differentiation to be blocked, resulting in deformed fruit. Use a nutrient root with a diameter of about 10 cm to protect the roots. "Tomato King" is a high temperature after the seedlings. In this period, it is generally allowed to grow naturally, and it is not necessary to control the seedlings.
Third, re-application of base fertilizer, timely planting
Generally, more than 5,000 kg of high-quality decomposed farmyard manure is applied, with 100 kg of phosphate fertilizer and 10 kg of ammonium phosphate. Before the planting of the seedlings for a week, the seedlings have the best trend and no seedlings. Planting fields should try to avoid heavy cropping with solanaceous crops, especially eggplant. Four-layer covered special early-maturing cultivation can be planted from mid-December to early February; single-layer greenhouses are planted from late March to mid-April. The planting density is 4,000 plants/mu of protected land and 3,500 plants/mu of open land.
Fourth, after the management of "Tomato King" planting slow seedlings, combined with irrigation should be immediately topdressed once, 20 kg of diammonium. In order to prevent ammonia poisoning in the protected area, it is possible to apply decomposed cake fertilizer or farmyard manure. In order to prevent premature aging of the upper part of the plant, when the first ear grows to the size of the walnut, the acre is applied with 15 kg of urea or 25 to 30 kg of compound fertilizer. When the second ear is inflated, the manure is 2,000 kilograms of manure and excrement, and 0.2% potassium dihydrogen phosphate or 0.2% plant nutrition treasure is sprayed on the foliage. No seedlings are controlled during the growing period to keep the soil moist in the field. In the early spring low temperature, "Tomato King" is easy to fall and fall, can be treated with 2,4-D or anti-fallin. 2,4-D is used at a concentration of 1% to 2%; the use of the anti-fallin is from 3% to 5%, and in this range, the lower the temperature, the higher the concentration used. "Tomato King" is an extensive management type, which does not require pruning, but because the single fruit is heavier, it should be framed in time to prevent lodging. The two ears of the fruit were cultivated in the protected area, and 4 ears were left in the open field, 3 per ear. When the first ear is grown, the lower old leaf is removed for ventilation and light transmission.
5. Pests and diseases control pests and diseases should be based on prevention and control. The first is to carry out the rotation, try to avoid heavy smashing; the second is to do a good job of disinfection and sterilization, and strictly control the humidity. Old vegetable areas or continuous plots should be disinfected and sterilized by seeds, seedbeds, nutritious soils, etc., and the cultivation of protected areas should strictly control the humidity in the shed; the third is chemical control. The main diseases of "Tomato King" include gray mold, disease, rickets, and viral diseases. Botrytis cinerea can be sprayed with 50% cyclazone or 50% chlorhexidine 1500 times solution. The disease and rickets can be prevented by 75% chlorothalonil or 64% anti-virus 矾 500 times. In the greenhouse or greenhouse cultivation, the above three diseases can be alternately fumigation with a smoked smoke agent No. 1 and No. 2, and the effect is better. On the basis of controlling aphids, the virus disease is controlled by 5% bacteria toxic clear 400 times liquid or 20% virus A500 times liquid. When the condition is heavier, it is better to use 5% bacteria to clear 600 times +83 antagonist 500 times +20% virus A500 times liquid compounding agent. Insect pests mainly include aphids and cotton bollworms. The aphids can be treated with a net (10% imidacloprid) 5000 times or 25% indigo 800 times solution. Helicoverpa armigera can be controlled by DuPont Wanling 3000 times or beta-cypermethrin 3000 times or taibao 2000 times solution. The above agents are used once every 7 days to 10 days, sharing 2 to 3 times. Attention should also be paid to the alternating use of different agents to prevent production and bioavailability.
Sixth, timely red, mention the morning market
If you want to ripen, you need to wait for the umbilical color to change. When you see the red dot, you can use 0.05% to 0.08% multiples of ethephon to apply the green fruit, or use the green fruit to use the ethephon 0.1% to 0.2% liquid soaked fruit, and put it at 25 °C. Reddening at 28°C, generally available 6 to 7 days in advance.
