Title:
METHOD FOR PREDICTING GREENHOUSE TOMATO FRUIT GROWTH
Document Type and Number:
WIPO Patent Application WO/2018/103137
Kind Code:
A1
Abstract:
Method for predicting greenhouse tomato fruit growth, comprising the following steps: 1, with the leaves of a tomato plant as sources and libraries and the stems and fruits as libraries, converting into source-library relations; with the sources as power sources and the libraries as resistances, converting the tomato plant into a circuit on the basis of the source-library relations; 2, utilizing relevant conditions in a greenhouse and the circuit in step 1 to determine a leaf voltage, a leaf resistance, an inter-node resistance, and a fruit resistance of the greenhouse tomato plant; 3, in combination with the circuit of step 1, calculating the voltage and current at either end of the fruits on the basis of the determined leaf voltage, leaf resistance, inter-node resistance, and fruit resistance by utilizing the Ohm's law to produce the electric power of the fruits, the value of the electric power of the fruits being the amount of assimilated products acquired by the greenhouse tomato fruits in one day; and 4, converting the produced amount of the assimilated products of the fruits into the diameter of the greenhouse tomato fruits. The method expresses in the form of electricity the inter-plant distribution of greenhouse tomato assimilated products, thus further facilitating greenhouse environment regulation and nutrient solution management.
