Cherry tomato soilless cultivation method

Abstract

The invention discloses a cherry tomato soilless cultivation method comprising the three aspects of soilless cultivation medium preparation, water-fertilizer integral application, and trimming and pruning. The soilless cultivation medium adopts a coconut coir composite medium. The trimming and pruning step comprises branch arrangement, trunk reservation, vine guiding, string hanging, flower and fruit management, and plant shape maintenance. According to the invention, the coconut coir composite medium is adopted, and irrigation water amount, fertilization amount, fertilization time and the like are controlled with the water-fertilizer integration technology, such that fertilizer-water management matches the trimming and pruning manner. With the method, tomato intrinsic growth and development characteristics can be developed; and the relationship between vegetative growth and reproductive growth is coordinated. The high-yield potential is explored while quality is improved. Also, facility and cultivation management processes can be simplified; tomato cultivation water-fertilizer utilization rate can be improved. Therefore, cherry tomato yield and quality are improved, and tomato industrialization development can be promoted.

Description

technical field [0001] The invention belongs to the field of agricultural production, and in particular relates to a soilless cultivation method for cherry tomatoes. Background technique [0002] Soilless cultivation mainly includes aeroponics, hydroponics and substrate cultivation, among which the key to substrate cultivation lies in the selection of substrates. The coconut bran composite substrate is popular for its advantages of light weight, low price, breathability and fertilizer retention, high quality and environmental protection, and it has also achieved remarkable results in the soilless cultivation of cherry tomatoes. For example, Gao Ming et al. (2010) proposed coconut bran substrate cultivation to make the annual output of tomato reach 268935kg / hm 2 , and the growth period is more than 1 year. It has also been found that using water and fertilizer integration technology to precisely control the amount of irrigation water, fertilization amount and fertilization ...

AI Technical Summary

Problems solved by technology

Due to the shortcomings of high water and fertilizer requirements, premature senescence, short fruiting period, and cumbersome management, the traditional pruning method cannot give full play to the production potential of unlimited-growing cherry tomato varieties, especially for the soilless cultivation of cherry tomatoes

Among them, the single-stem pruning method is suitable for dense planting, has good early maturity and simple technology, but it uses a large amount of seedlings, high cost, and the plants are prone to premature aging, and the total output is not high; the double-stem pruning method can save the cost of seeds and seedlings, and the plant growth period is long. , vigorous growth, long fruiting period, high yield, but low early yield and poor precocity; continuous pruning and head pruning can improve quality, prolong the fruiting period, and increase yield, but the operation is relatively cumbersome and requires sufficient fertilizer and water to prevent premature senescence
