"Tomato King" (cooperation 906) is easy to set fruit, high yield and transport resistance. Its cultivation technology is different from that of ordinary tomatoes, and now its key cultivation measures are described as follows:
First, reasonably determine the time of sowing and raising seedlings
If greenhouses, sheds, plastic mulches and straw mulch are used for the early ripening cultivation, the sowing and nursery time should be selected from xiadian in October to early November; use medium and large sheds + mulch cultivation, from late November to December. Sowing seedlings in the middle.
Second, the fat bed dilute broadcast, nutrition, eucalyptus root cultivating the strong "tomato king" generally 30 grams per mu species, the use of fat bed dilute sowing, seedlings per square meter planting about 3 grams. When the seedlings grow to two leaves and one heart when selecting sunny seedlings, it is too late to cause flower bud differentiation to be blocked, resulting in malformed fruit. With a diameter of about 10 cm nutrients to protect the root seedlings. "Tomato King" hi hi after sub-seedling, this period is generally allowed to grow naturally, without controlling the seedlings.
Third, re-basal fertilizer, timely planting
Generally more than 5,000 kilograms of high-quality perishable farmyard manure, with 100 kg of phosphate fertilizer, ammonium phosphate 10 kg. One week before planting seedlings, seedlings have the tendency to grow longer and grow longer. Planting fields should try to avoid replanting with solanaceous crops, especially eggplants. Four-layer cover 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 4000/mu of protected land and 3500/mu of open land.
Fourth, management "Tomato King" after the establishment of slow-onset seedlings, combined with irrigation should immediately top-dressing, Mushi diammonium 20 kg. In order to prevent ammonia poisoning in the protected area, it is possible to apply cooked cake or manure. To prevent premature failure of the upper part of the plant, when the first ear grows to the size of the walnut, 15 kg of urea or 25 to 30 kg of compound fertilizer is topdressed. When the second ear enlarges, Mushi treats 2000 kilograms of manure urine, and sprays 0.2% potassium dihydrogen phosphate or 0.2% phytochemical treasure on the leaves. There is no need to control seedlings during the growing season to keep the soil moist. In the early spring when the temperature is low, “Tomato King†is easy to drop and drop, and it can be treated with 2,4-D or anti-dropping agent. The use concentration of 2,4-D is 1% to 2%; the use concentration of anti-dropping agent is 3% to 5%. In this range, the lower the temperature, the higher the use concentration. "Tomato King" is an extensively managed variety and does not require pruning. However, due to the heaviness of the single fruit, it should be promptly erected to prevent lodging. Protected cultivation of two spikes leaving fruit, leaving 4 ears exposed, 3 per panicle. When the first ear grows, the lower old leaves are removed for ventilation.
Fifth, pest and disease prevention and control pests and diseases should be based on prevention and treatment. The first is to conduct crop rotations to avoid smashing; the second is to do a good job of disinfection and sterilization, and strictly control the humidity. The old vegetable plots or continuous cropping plots shall be capable of disinfecting and sterilizing all seeds, seedbeds, and nutritious soils. The protective plots shall be under strict control of the humidity in the greenhouses; and the third is the control of chemical agents. The main diseases of Tomato King include gray mold, disease, damping-off, and viral diseases. Botrytis can be sprayed with 50% fasting or 50% acetaminophen 1500 times. Bacteria, damping-off can be controlled with 75% chlorothalonil or 64% antiviral 500 times. In the greenhouse or greenhouse cultivation, the above-mentioned three diseases can be alternately fumigated with No. 1 and No. 2 of a smoke and smoke agent, and the effect is better. Virus disease is controlled on the basis of controlling aphids, using 5% strains of virus to clear 400 times liquid or 20% of virus A500 times. When the disease is severe, it is better to use 5% strains of virus and 600 times more +83% of the anti-agents and 20% of the A500 times of the virus. Insect pests mainly include aphids and cotton bollworms. The aphids can be treated with net (10% imidacloprid) 5000 times or 25% indole teeth 800 times once. The cotton bollworm can be controlled by 3000 times of DuPont Wanling or 3,000 times of high efficiency cypermethrin or 2000 times of Citaibao. The above medicines are used once every 7 days to 10 days, and are shared 2 to 3 times. Attention should also be paid to the alternate use of different agents to prevent production and drug resistance.
Sixth, timely reminder red, mention morning market
For mature ripening, wait for the umbilical color to change, and when seeing the red spot, apply 0.05% to 0.08% multiple times of ethephon to smear the green fruit, or collect the green fruit and soak the fruit with 0.1% to 0.2% of ethephon and place it at 25°C. Redness is expected at 28°C and can generally be listed 6 to 7 days in advance.
