Cherry tomato cultivation technology

Transplanting or transplanting

When transplanting cherry tomatoes, the temperature of the 10cm soil layer is required to be stable and above 10C. Transplanting density should be flexibly determined based on factors such as species, pruning method, number of ears left, growth period, soil organic matter, etc. Ornamental planting should be less rigid than production planting. The transplanting method should be dark water transplantation during the low temperature season, so that the soil temperature will not drop and the seedlings will slow down quickly. If the temperature of the 10cm soil layer reaches above 15℃ during transplanting, open water transplanting can be used. Transplanting depth - generally it is appropriate to bury the tender leaf nodes or slightly deeper.

For potted tomatoes, use round pots with a diameter of 25~30cm, or use brick transplanting troughs with a width of 40cm and a height of 30~40cm. Bonsai soil is prepared by mixing 4-6 parts of vegetable garden soil, 2-4 parts of composted farmyard fertilizer (depending on the fertility level of the vegetable garden soil), and 2 parts of fine sand or coal ash. Add 1.0 diammonium phosphate per cubic meter. kg, ammonium sulfate 0.5kgo when transplanting, 1 seedling per potted plant. After transplanting, place the pots according to the design requirements and pour light water immediately to promote slowing down of the seedlings. Fertilization

Add seedling fertilizer: If the base fertilizer is not enough, the seedlings will not grow well after transplanting. You should topdress and add seedling fertilizer while watering the seedlings slowly. Generally, each cherry tomato is topdressed with about 3g of ammonium chloride, and then poured with seedling slowing water. This fertilizer is crucial for mature species.

Fruit-promoting fertilizer: When the seedlings are finished, use fruit-promoting fertilizer with fruit-promoting water to promote both fruit and seedlings. Generally, each cherry tomato uses about 6g of ammonium phosphate, and the amount of fertilizer applied should be sufficient, accounting for 30-40% of the total fertilizer amount. This fertilizer has an important effect on the rapid expansion and perfection of the fruit and increasing early production.

Fertilization during the high-yield period: Fertilization during the high-yield period is generally carried out 2 to 3 times. Chapter 1: After the fruits are harvested, apply a quick-acting fertilizer. You can use about 5g of diammonium phosphate for each cherry tomato. In addition to meeting the requirements for the growth and development of the second and third fruits, this fertilizer can also prevent the weakening of vegetative growth and premature aging caused by excessive fruit bearing. After the second fruit harvest, which coincides with the harvest and maturity period, attention should be paid to reasonable fertilization. It is best to use light compound fertilizer, 3-5g per cherry tomato, or 3g diammonium phosphate plus 1.5g potassium nitrate.

Extra-root fertilization: In order to promote the growth of stems and leaves, promote the fruit to mature and prevent senescence, external fertilization can be carried out during the fruit and maturity period in conjunction with pesticides to prevent diseases. Common chemical fertilizers include: 0.3~0.5 urea solution, 0.2-0.3 potassium dihydrogen phosphate, 2~3 phosphate fertilizer, 3~5 herb ash, 50~100mg/kg boric acid or sodium dihydrogen phosphate, etc.

Water and fertilizer management for potted cherry tomatoes: The soil space of potted cherry tomatoes is relatively small, and the nutrient supply is limited. The management of liquid fertilizer is based on the principles of strengthening the seedlings, promoting fruit, and harmonizing the differences between the seedlings and fruits. It is difficult for potted tomatoes to use liquid fertilizer management to expand fruit shape and increase fruit weight. The key is to increase the number of fruits to improve efficiency. Because each cherry tomato has a large number of fruits, the standards for liquid fertilizer are much higher than those on the street. In addition to applying sufficient base fertilizer, after the first inflorescence is in full bloom and the fruits are established, top-dress each pot with 5~10g of compound fertilizer or 5g of diammonium phosphate. When the second flower spike is in full bloom, top-dress with 3~5g of compound fertilizer per plant. Fertilize once every 15 to 20 days. In the middle and later stages, the potassium fertilizer content can be appropriately increased. Fertilization of the leaves can be completed after each fruit harvest.
