Abstract

The invention discloses a controlling method of vegetative growth and reproductive growth in tree-type cultivation of tomatoes. The method is essentially characterized in that: growth and development of the tomatoes during vegetative growth period and reproductive growth period are controlled in a greenhouse by using nutrient solution during the vegetative growth period and nutrient solution during the reproductive growth period, and combining with the control of the temperature, pH value and EC of the nutrient solution as well as the temperature, humidity, illumination intensity of the greenhouse, etc., thus the tomatoes achieve cultivating in yearround, and have the advantages of rapid growth, long fruiting period, high yield and good quality.

Description

technical field [0001] The invention relates to a tomato cultivation method, in particular to a method for regulating vegetative growth and reproductive growth of tomato tree cultivation. Utilizing the method of the invention can cultivate the tomato every year, and has the advantages of fast growth, long production period, high yield and good quality. Background technique [0002] In conventional production at present, what tomato adopts is soil cultivation or greenhouse soilless cultivation method. However, the segmented cultivation of spring or autumn stubble is generally adopted, and the fruiting capacity of each tomato plant is only 10 to 16; due to the high temperature in summer and low temperature in winter, long-season cultivation with annual growth is rarely used; and due to the difficulty of management, The advanced cultivation technology of hydroponics, which has fast growth, high yield and good quality, is rarely used. [0003] Tomato tree cultivation is a spec...
