1, sowing seedlings
Seedlings can be planted throughout the year, and dwarf varieties with strong disease resistance, strong resistance and easy fruit setting can be selected. Such as dwarf red bell, dwarf yellow bell, potted red, colorful and so on. Before sowing, use the warm water of 55 °C for 30 minutes, then naturally reduce to normal temperature, continue to soak for 4-6 hours, then germination for 2-3 days at 25-28 °C, during the germination, pay attention to wash with warm water every day. Wash the mucus attached to the seed to prevent the seeds from decaying. When the tomato seeds are white buds, they can be sown in a 5 cm diameter nutrient mash. The base material is made of grass charcoal, vermiculite, fine sand, cotton cake, slag, corn stover powder, etc., and optionally three of them are mixed in a ratio of 1:1:1. Each seed has 2 seeds, 0.8 cm of fine tidal soil after sowing, and covers 1 layer of film, and the film is removed after emergence. In the high temperature season in summer, the sunshade net or grasshopper is used to cool down to prevent seedlings, and in winter, protection facilities are used to prevent freezing damage. When two leaves are one heart, the seedlings are fixed. It is also possible to use seedlings to grow seedlings, and to wait until the seedlings grow to 2 leaves and 1 heart. 0.5% potassium dihydrogen phosphate can be sprayed before the upper basin to increase seedling nutrition and cultivate strong seedlings. Spraying the zinc and chlorothalonil to prevent seedling disease.
2, the upper pot colonization
When the seedlings have 4-5 leaves, they can be placed on the basin. The pots of 28×30 cm are selected, and 4 pots are planted in one pot. The number of plants can also be determined according to the size of the pots. The base material is made of peat, vermiculite, fine sand, mushroom residue, slag, corn stover powder, etc., and 3 of them are mixed with Datian soil in a ratio of 1:1:1:3, and each pot can be mixed with 100g of puffed chicken. Manure, 5 ternary compound fertilizers to ensure that the matrix provides adequate nutrition. Watering after planting.
3, daily management
After slow seedlings, in the hot summer season, water is watered at least once a day, watered once every 2-3 days in spring and autumn, and once in winter. Before the fruit is hung, the soil is diligent and the permeability is increased, which is beneficial to the development of the root system. After the fruit is hung, 100 grams of puffed chicken manure and 5 ternary compound fertilizers are applied, and 0.5% potassium dihydrogen phosphate is sprayed appropriately to provide the nutrients needed for fruit growth. Into the fruit expansion period, the soil must be kept moist, but watering should be appropriate, not too much watering, too much work, to prevent roots, yellow leaves, rotten leaves, fruit drop. In the summer, it can be covered with a sunshade net to prevent the fruit from burning in the summer; when the fruit matures, avoid spraying water to prevent cracking. Pay attention to cold protection in winter to prevent freezing damage.
4, pruning
Dwarf tomatoes belong to the self-sealing top variety, the internodes are extremely short, and the plants are extremely dwarfed. Generally, no pruning or scaffolding is required. However, if the plant body is small, the flower buds or fruit can be destroyed when there is no fruit hanging or the fruit is not inflated, so that the plant body continues to grow, and 3-4 side branches are retained. If there are too many fruit sets, you can use the cylindrical support of fine steel bars (fine reinforced paint is painted in pure white). You can also insert a strong bamboo stick in the middle of the pot to make the rack. The bamboo stick should not exceed the height of the tomato, so as not to affect the appearance. In the whole growth process, the side branches of the base are removed in time, and it is found that the old leaves of the base should be removed in time to facilitate ventilation and light transmission, thereby reducing nutrient consumption. Dwarf tomatoes generally do not be shaped, but can be simply shaped according to the shape of the flower pot and local consumption habits to enhance the ornamental nature of potted dwarf tomatoes.
5, timely sale
Potted dwarf tomatoes are generally sold in time when the fruit begins to mature. The lower old leaves and yellow leaves should be removed before sale to expose the fruit to enhance the appearance. It can also be sold during the green fruit period and during the ginkgo period.
6, indoor maintenance
Potted dwarf tomatoes can be placed on the family balcony, indoors, and on the desk. In winter, the indoor temperature is high, and the temperature difference between day and night is small, which is not conducive to tomato growth. At night, it should be placed at a relatively low temperature, so that the temperature difference between day and night is about 5-10 degrees. Generally, the indoor air is dry. It is necessary to pay attention to the water spray on the foliage. Spray 0.5% potassium dihydrogen phosphate or rice vinegar 100 times a week to prevent insects, disease and foliar fertilizer. Potted dwarf tomatoes on the desk should be exposed to the sun every 2-3 days, which is conducive to plant growth. After the fruit is ripe, it is picked and eaten in time to prevent over-ripening and cracking.
Management points after cultivation of potted tomatoes
1. Growth period management: including cultivating and weeding, water storage and protection, tying vines, pruning, removing old leaves, ventilating and lightening, strengthening pest control, and strengthening temperature management. Temperature management is to increase the ventilation of the shed during the day, so that the temperature inside the shed is maintained at around 25 °C. The night temperature is maintained between 10 and 13 °C. When the wind starts to be released, the air outlet should be small to large, from small to large. After the temperature drops in the afternoon, the air outlet will gradually become smaller or closed.
2, fertilizer management: the growth period of tomatoes in the summer and autumn rain season generally do not need watering, but when the 1-3 spikes mature when the drought, should also be properly watered. According to the growth of tomato plants, timely topdressing to promote fruit development, preserve flowers and preserve fruit. Generally, the base fertilizer can be applied to the microbial fertilizer, and the top dressing can be applied to the shell and the sweetener to make it look more delicious. Conditional can be followed by cakes such as bean cake and cottonseed cake.
3. Pruning management: During the growth process of tomatoes, each leaf will grow out of shoots, and the young shoots below the first inflorescence should be removed in time to avoid affecting the consumption of nutrients, fruit harvesting and yield. After 6 inflorescences, the tomato plants are topped to the top, and the nutrients are controlled to supply only the fruits to ensure yield.
