Abstract

The invention discloses a high-sugar tomato substrate cultivation method which is particularly characterized by including the steps: adjusting supplying amount of nutrient solution at different growthstages of tomatoes; supplying 180-230ml of nutrient solution for each tomato every day at a vegetative growth stage of the tomatoes; supplying 360-460ml of nutrient solution for each tomato every dayat a flowering and fruiting stage; irrigating the tomatoes with the nutrient solution for three times every day. Substrates for tomato growth comprise grass carbon, vermiculite, granular organic fertilizers and powdered organic fertilizers, the ratio of the grass carbon, the vermiculite, the granular organic fertilizers and the powdered organic fertilizers is (2-3):(1-2):1:1, and the ratio of K and N in the nutrient solution is (2.8-3.0):1. The tomatoes cultivated by the method are high in sugar degree and good in quality, the fertilizers can be saved, and economic benefits are improved.

Description

technical field [0001] The invention relates to the field of vegetable matrix cultivation. More specifically, the present invention relates to a kind of high sugar content tomato substrate cultivation method. Background technique [0002] Substrate cultivation is the most widely used cultivation method in soilless cultivation in my country. It is a cultivation method in which the root system of the plant is fixed on a solid substrate, and the plant absorbs nutrients and oxygen from the substrate by applying water and fertilization, thereby realizing soilless cultivation. At present, there are many types of substrates used in substrate cultivation. Commonly used inorganic substrates include vermiculite, perlite, rock wool, sand, polyurethane, etc.; organic substrates include peat, rice husk charcoal, bark, etc. The use of soilless cultivation can reduce costs, and the production process is simple, which can effectively improve production efficiency. [0003] Tomato is one ...
