It can cure thirst and loss of appetite. Can be put or added in cold dishes or clear soup. The root system is developed, the regeneration ability is strong, and many lateral roots occur, most of which are distributed in the soil layer 30 cm above the soil surface. Plants grow strongly, with stems and vines self-capped, and fewer varieties; There are infinite growth, and the plant height is more than 2 meters. The leaves are odd-numbered pinnate compound leaves with many thin leaflets.
The fruit is bright, with red, yellow, green and other fruit colors. The weight of a single fruit is generally10 ~ 30 grams, and the fruit is mainly spherical. The seeds are smaller and heart-shaped than ordinary tomatoes. Densely furred, 100-grain weight1.2 ~1.5 kg.
The fruit is about1~ 3 cm in diameter and bright red. The suitable temperature for the growth and development of cherry tomatoes is 20 ~ 28℃, and the temperature for seed germination is 25 ~ 30℃, which is lower than 14℃ and it is difficult to germinate. The temperature in the seedling stage is 20 ~ 25℃ during the day and10 ~15℃ at night. During the flowering and fruit-setting period, the plants grow slowly at 20 ~ 28℃ during the day and15 ~ 20℃ at night, which is lower than 15℃. When the temperature is higher than 35℃, the plants grow slowly, which will also cause flowers and fruits to drop. The fruit development period is generally 24 ~ 28℃ during the day and16 ~ 20℃ at night, and the temperature difference between day and night is maintained at 8 ~10℃. (1) Seedbed preparation. The seedbed should be sheltered from the wind and sunny, with good drainage. A 667-square-meter field needs 6-7 square meters of seedbeds and 35-40 square meters of seedbeds. Every 667 square meters of subsoil of seedbeds should be covered with decomposed human excrement and urine 1500 kg, and it should be covered with 8 cm thick nutrient soil.
(2) sowing date. Sow in advance appropriately and extend the harvest period as much as possible. Using small arch shed to raise seedlings can not only sow early, but also reduce the occurrence of seedling diseases. Sowing is usually done in late April.
(3) soaking seeds to accelerate germination. 20 grams of 667 square meters seeds were soaked in potassium permanganate 1000 times solution 10 minute, then washed with clear water and soaked in warm water for 6 hours, then the seeds were washed, drained, moistened with wet gauze, germinated at about 25℃, and sowed after exposure.
(4) Sowing and post-sowing management. In order to ensure a high rate of adult plants, it is required to sow seeds in separate grains and cover them with nutrient soil of 0.5 cm. Maintain a high temperature before emergence, and pay attention to ventilation to prevent excessive growth after emergence. At the stage of two leaves and one heart, select healthy and disease-free seedlings, and carry out "three zones" of heel in with fertilizer, medicine and soil in sunny evening, with seedbed in heel in and seedbed in heel in, and then irrigate root water.
(5) Prevent seedling diseases and control overgrowth. There are many diseases in tomato cultivation areas, and damping-off and early blight can be controlled by copper ammonium complex or Luheng 2. Spray 1 time every 7 ~10 days for 2 ~ 3 times. Spraying 1500x 10-6 for a long time, or spraying 300x 10-6 chlormequat, according to the seedling growth, can increase the leaf color and inhibit the overgrowth. The growth is too strong, and it will be sprayed again in three weeks.
