Fixed-point automatic-fertilization method for seedlings planted in greenhouse

Abstract

The invention discloses a fixed-point automatic-fertilization method for seedlings planted in a greenhouse. The method comprises the following steps: step 1, a chemical fertilizer conveying plate is arranged in the middle of the upper part of a fertilization machine frame, a plurality of chemical fertilizer conveying through holes are arranged around the chemical fertilizer conveying plate, a conveying plate rotating shaft is arranged in the middle of the chemical fertilizer conveying plate, and a tray for preventing a chemical fertilizer from falling from the chemical fertilizer conveying through holes is arranged at the bottom surface of the chemical fertilizer conveying plate; step 2, a chemical fertilizer storage bucket is arranged on the part, located at the rear part of the chemicalfertilizer conveying plate, of the fertilization machine frame, the chemical fertilizer is placed in the chemical fertilizer storage bucket, the chemical fertilizer storage bucket is provided with a chemical fertilizer outlet groove, the side edges of the chemical fertilizer conveying plate and the tray are inserted into the chemical fertilizer outlet groove, and when the chemical fertilizer conveying plate rotates, the chemical fertilizer dropped in the chemical fertilizer conveying through holes is discharged; step 3, a fertilizer guiding cylinder limit pipe is arranged at the part, locatedin the front of the chemical fertilizer conveying plate, of the fertilization machine frame, and the interior of the fertilizer guiding cylinder limit pipe is a chemical fertilizer conveying and guiding passage; and step 4, the upper end of a lifting fertilizer guiding cylinder is inserted into the part, located at the lower end of the fertilizer guiding cylinder limit pipe, of the chemical fertilizer conveying and guiding passage.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a fixed-point automatic fertilization method for seedlings planted in greenhouses. Background technique [0002] At present, vegetables are fertilized in greenhouse vegetable sheds, and different chemical fertilizers are applied according to different stages of vegetable growth. The existing fertilization methods are generally mixed in water and watered to achieve the purpose of fertilization. The above methods are not targeted, and the fertilizer cannot reach the roots of the crops directly, and the fertilizer is seriously wasted. Fertilizing the soil with unnecessary fertilizer will cause the soil to harden when the time comes. affect crop growth. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and the purpose is to provide a fixed-point automatic fertilization method for seedlings plante...
