Leafy-vegetable growth rate promoting device based on high-voltage pulsed electric field

Abstract

The invention provides a leafy-vegetable growth rate promoting device based on a high-voltage pulsed electric field. The device comprises at least one culture bed and a high-voltage pulsed power supply used for supplying high-voltage pulsed voltage for the culture bed, wherein a nutrient solution is filled in the culture bed; twp outer side surfaces of the culture bed are respectively and fixedlyprovided with a high-voltage electrode and a low-voltage electrode; the high-voltage pulsed power supply is connected with the high-voltage electrode; the low-voltage electrode is earthed; the high-voltage electrode and the low-voltage electrode are in parallel arrangement; a pulsed electric field area is formed between the high-voltage electrode and the low-voltage electrode; and a plurality of field planting baskets are arranged in the pulsed electric field area. The device provided by the invention has the following advantages: the high-voltage pulsed electric field generated by the high-voltage pulsed power supply is added to two poles of the culture bed, so electroporation of root cells of leafy vegetables cultured in the culture bed is generated; the permeability of a root cytomembrane is changed; the absorption of mineral elements is accelerated; and the growth of the leafy vegetables is promoted.

Description

technical field [0001] The invention relates to the field of leafy vegetable planting, and more particularly relates to a device for promoting the growth rate of leafy vegetable based on a high-voltage pulsed electric field. Background technique [0002] In the field of leaf vegetable cultivation, the nutrient solution cultivation method has the advantages of good product quality, water saving and fertilizer saving, and is not restricted by seasons and regions, so it is widely used. The vast majority of leafy vegetables are produced using hydroponics. In order to obtain the maximum economic benefits, leafy vegetables are generally produced in an annual continuous manner. Therefore, the growth efficiency of leafy vegetables has become a key technical issue that affects the economic benefits of facility agriculture.
