Mantian 206 is a new long-orange cherry tomato introduced from Taiwan in Henan Province. Through planting for several years, the variety showed strong heat resistance, cold resistance and disease resistance. When the plants are cultivated in summer in greenhouses covered with insect nets, Mantian 206 can still normally bloom at high temperatures of 37°C, and virus diseases rarely occur. The fruit of the variety has aroma after ripening, the hardness of pulp is high, storage and transportation is good, and the commodity is good. The yield per mu produced in autumn and winter pods is about 7000 kilograms. The cultivation techniques are summarized as follows:
First, seedlings use nutritious seedlings, nutritious soil available sawdust, cinder, decomposition of organic fertilizer in accordance with the ratio of 6:2:2, with a good addition of 20 grams of carbendazim per cubic meter of nutrient soil, mix well after the heap Boring for 15 days, and then making nutrients. The Mantian 206 cherry tomato seeds sold on the market have been sterilized and do not need to be separately treated when sowing. The amount of seed per acre is 5 grams. After soaking and pregerminating on July 12, one seed per seedling is planted, and then 1 cm thick nutritious soil can be covered on the nutrient bowl.
Second, seedbed management
In July, when the high-temperature season is in progress, there are many insect pests. Nursery should be conducted in a greenhouse covered with insect-proof nets, and shade nets should be covered. When the seedbed is dry, water is sprayed in time to keep the seedbed moist; in rainy days, it is covered with a plastic film to prevent the rain from leaching. Immediately after the heavy rain spray with chlorothalonil, Preclo, Ledomil and other fungicides to prevent the occurrence of diseases.
3. Prepare 6,000 kg of decomposed pig manure, 50 kg of diammonium phosphate and 30 kg of potassium sulphate per acre before site preparation and fertilization. Deep plowing shall be conducted for 25-30 centimeters to level the ground.
Fourth, colonization
On August 16th, wide-narrow rows were planted with high-altitude ridges, with a width of 90 cm and a narrow row spacing of 60 cm. Rigging on a wide line, ridge height 20 to 25 cm, covering the film after the colonization. The planting distance was 40-45 cm, the density was 1800-2000 plants/mu, and the plants were irrigated.
Fifth, management technology
1. Temperature management: The temperature in the early stage is high, and the amount of ventilation should be increased to reduce the temperature in the shed. The temperature is controlled at 25°C-30°C in the seedling stage, the temperature is controlled at 20°C-25°C during the flowering period, and the temperature is controlled at 22°C-27°C during fruit setting and fruit growth period. After October, the temperature gradually decreased. Insulation measures should be strengthened. Grasshoppers should be stamped in time. Warming measures can be taken when necessary.
2. Humidity management: Since the humidity in the booth is high and it is susceptible to diseases, ventilation should be strengthened to reduce the humidity. Can also be used to cover the ground wheat straw, drip irrigation and other measures to reduce the humidity, so that the shed to maintain the humidity of about 80%.
3. Water and Fertilizer Management: After pouring enough water, it is generally no longer watered or fertilized before flowering. When the plant has two spikes basically sitting (before and after October 10th), the slurry is applied with a concentration of 70% of biogas slurry, and the second time is applied after 10 days. On November 7th, 15 kg of urea, 7.5 kg of diammonium phosphate, and 7.5 kg of potassium sulfate were applied per acre of water. Since the temperature is low, the water evaporates less, and the plants grow slowly. It is not necessary to water and fertilize.
4. Pruning and preservation of fruit: Mantian 206 cherry seedlings, fruit set rate is higher, when the cultivation of single vine pruning management measures, each plant stay 7 panicle topping, fruit 20 to 30 per panicle. In addition, extra heads and florets must be removed so that nutrients can be supplied in a concentrated manner. In the full flowering period, the tomato fruiting agent No. 2 sprayed with 400 times liquid can increase the fruit setting rate. After the growth of the lower part of the ear, the lower old leaves and diseased leaves will be promptly destroyed to reduce the consumption of nutrients, increase the lower light, and increase the ventilation, in order to facilitate the conversion of the fruit and provide the morning market.
