AI Technical Summary

Technical Problem

During the cutting propagation of kudzu stem segments, the stem segments slide in the soaking container, causing the buds to come into contact with high concentrations of growth regulators, which affects germination and growth. In addition, the soaking is uneven, which reduces the survival rate and seedling quality.

Method used

The stem segments are secured using a fixing basket and a silicone fixing nozzle to ensure that only the base is immersed in the regulator solution. The fixing basket is lifted by a control component to drain the solution, and the solution volume is precisely controlled by a liquid level sensor to prevent the buds from coming into contact with the solution and to avoid uneven soaking.

Benefits of technology

It improved the survival rate of cuttings and the stability of seedling quality, reduced the waste of regulators, and improved seedling efficiency and continuity.

Abstract

The invention relates to the technical field of pueraria lobata stem cutting, in particular to a pueraria lobata stem cutting regulator precise dosing device which comprises a soaking tank, a fixing basket is arranged in the soaking tank, the height of the fixing basket is 2 / 3 of that of the soaking tank, the outer side wall of the fixing basket is in sliding fit with the inner side wall of the soaking tank, and supporting plates which are symmetrically arranged are fixedly connected to the top of the fixing basket; the bottoms of the supporting plates make contact with the top of the soaking tank, a plurality of positioning holes are formed in the bottom wall of the fixing basket, a plurality of silica gel fixing nozzles corresponding to the positioning holes are fixedly connected to the bottom of the fixing basket, and control assemblies are symmetrically arranged on the soaking tank. By means of the positioning holes and the silica gel fixing nozzles on the fixing basket, pueraria lobata stems are accurately fixed, it is ensured that only the bases are soaked in a conditioning agent solution, bud heads are prevented from being damaged, meanwhile, it is ensured that the soaking depth of the stems is consistent, the seedling growing quality stability is improved, and the problems that in a traditional soaking device, the stems are prone to sliding, the bud heads are prone to being damaged, and the soaking effect is uneven are solved.
