Soilless cultivation method of cherry tomatoes suitable for tropical region

Abstract

The invention discloses a soilless cultivation method of cherry tomatoes suitable for tropical region. The soilless cultivation method includes the steps of 1), seed soaking to accelerate buds; 2), seedling raising; 3), shed fumigation; 4), planting; 5), growing season management; 6), management of fruit setting period of pollination. With the cultivation method, stable and high yield of the cherry tomatoes is achieved, and a balanced supply of the high quality cherry tomatoes 5 stubble a year is guaranteed; the sugar content of the fruit is stable above 9.5%, the yield of the cherry tomatoesis stable at more than 8500 per mu, and the product rate of the certified products exceeds 92%.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and relates to a method for cultivating cherry tomatoes, in particular to a method for soilless cultivation of cherry tomatoes suitable for tropical regions. Background technique [0002] Cherry tomatoes, also known as small tomatoes, pearl tomatoes, cherry tomatoes, can be both vegetables and fruits. Cherry tomatoes are annual herbaceous plants belonging to the genus Solanaceae. It has the effects of promoting body fluid and quenching thirst, invigorating stomach and eliminating food, clearing heat and detoxifying, cooling blood and calming liver, nourishing blood and increasing appetite. [0003] Most of the domestic cultivation methods of cherry tomatoes are soil cultivation methods, and the plants are planted on the field ridges of ridges. In this soil cultivation method, the nutrient elements will be fixed by the soil and cannot be absorbed by the plants, and there are sub- The problem of ...

AI Technical Summary

Problems solved by technology

At present, there are the following problems in the soilless cultivation method of millennium varieties: 1. Millennium varieties avoid heavy cropping, and only one crop can be planted every year, and non-grafted seedlings, that is, seedlings, cannot be planted continuously

2. At present, the main species planted in the hot zone of Hainan is still Millennium, but Millennium is not resistant to yellow leaf curl virus. In the past three years, the incidence of yellow leaf curl virus has been severe, showing earlier onset and faster spread. A more serious situation

3. The conventional millennium soilless seedling raising method uses pure coconut peat to raise seedlings. When fertilization is too early, the seedlings are easy to grow leggy in the tropical area of ​​Hainan;

Conventional millennium seedlings are mostly fertilized with compound fertilizer, urea or potassium dihydrogen phosphate 500-1000 times solution, the fertilizer effect is slow, and the nutrients are not comprehensive enough, commercial seedlings cannot meet the requirements of strong seedlings

4. Conventional millennium cherry tomatoes are cultivated without soil, and coconut peat is used as a single substrate for cultivation. The seedlings are prone to lack of fertilizer, resulting in a significant reduction in later production

If the amount of drip irrigation is greatly increased in order not to lack fertilizer, it is easy to affect the development of the root system and cause dead seedlings in the later stage.

At the same time, conventional millennium cherry tomatoes are fertilized, and the root system of the watermelon seedlings is irrigated with clean water on the day after planting. In tropical areas of Hainan, water and fertilize immediately, and Meiyue watermelon is prone to damping-off and other diseases

5. Conventional cultivation and fertilization methods of millennium cherry tomatoes are likely to cause calcium deficiency, boron deficiency and other trace elements in the plant, and the authenticity rate of the fruit is significantly reduced
