First, the biological characteristics: thermophilic, growth and development suitable temperature for the tiger to make 伥 23 28 28 °C, night temperature is 15 18 18 °C, like plenty of sunlight, the soil moisture requirement is 60 8 80%, with deep soil, loose fertile, PH slightly 6~6.5 acidic soil is appropriate.
Second, the varieties introduced:
Virgo: small fruit varieties, known as the best in the fruit. Early birth, fertility and disease resistance, high growth and unlimited growth, plant height up to 2.8m or more, 30 to 60 per ear fruit, fruit weight about 14g, bright red long ellipsoid, hard meat, thin, but resistant Storage and transportation, output up to 14000 kg / mu, the market price is high.
Millennium: small fruit varieties, early growth, sowing to harvest in the fall to 150 days, fertility and disease resistance, high growth unlimited type, plant height up to 250cm or more, 50 to 80 per ear fruit, fruit weight 20g , Pink elliptic fruit, slightly acidic in the meat with sweet, thin but not easy to crack fruit, storage and transportation, yield high.
Third, cultivation techniques:
1. Sowing and breeding acres:
(1) Sowing date: The millet skin is pink and suitable for winter cultivation. The fruit period is in March and May, and the market price is promising. General sowing in early October nursery, planting in November, listed in early March, may be over in May, listing concentrated.
(2) Soaking: soaking in warm water of 55°C, stirring for 6 hours at room temperature, then sowing in 70-hole trays, placing in the greenhouse for heat preservation, and promoting sprouting.
(3) Seedling management: plug seedlings should be promptly watered, and do pest control work. Insect nets can be used to seal all openings to prevent pests from migrating, especially aphids. When watering, it is necessary to add medicine (such as chlorophyllin plus chlorpermone hen or gankang 120) to prevent seedling disease.
(4) Fertilization and site preparation: Before the site preparation, apply 180 kg of diammonium phosphate, 50 kg of urea, 80 kg of potassium sulfate, about 500 kg of mature oil residue, and 5000 to 7000 kg of organic fertilizer. After deep-dip watering, fully dissolve the water and fertilizer. , increase ventilation, make it childbirth.
2. Colonization: After the tiller, the width is 60cm, the narrow line is 55cm, and the spacing is 35cm. The seedlings are placed in the afternoon, and the ridges are set up after seedlings. The ridge height is suitable to cover the pods, generally 15cm high, and then watered to stabilize the seedlings. After the tiller, a 1.2 m mulch film is planted in parallel.
3. Management: High-temperature and high-humidity management after planting, prompting easing of seedlings, followed by cooling and dehumidification, to control pupa roots, and to increase the temperature difference between day and night, to promote flower bud differentiation, lay a good foundation for future seizure of high yield.
4. Pruning: Although the millennium and the Virgin are infinitely growing, as economic cultivation, it is not required to grow indefinitely, but is artificially regulated, that is, begins to spread the fruit after the second panicle, and leaves the buds below the panicle. Train the main head and give it to the heart when the main head is left on the 7th floor. In the entire result process, you should use a fruit arbitrage or 2, 4 D D to make a point, in order to make a profit. In the middle and later stages of the results, half of the lower leaves can be cut off to facilitate ventilation and change color.
5. Diseases and Insect Pests: As a small tomato, the millennium and the virgin have wild characteristics and have excellent disease resistance. However, it is also necessary to prevent whitefly, leaf mold, and diseases.
Whitefly: It is ideal for use in DuPont Van Ling, Pou Xi Ling plus chlorophyll or flowering essence.
Leaf mold: leaf mold: In addition to strengthening the management, can be used clomazone or quick-king plus chlorophyll (flowering essence, sweet fruit essence) for drug control.
Blight: It can be controlled by agricultural antibiotics 120, DuPont Kelu or Preco Plus Green Leaf Extract (flowering essence, sweet fruit essence).
Fourth, harvest, packaging: According to the distance of transport, reasonable packaging, small tomatoes can also be used to increase its value.
