Description

A method for preparing highly breathable resin flower troughs for flower seedling breeding

Technical field

The present invention relates to the technical field of resin flower trough preparation, and specifically to a method for preparing a highly breathable resin flower trough used for flower seedling breeding.

Background technique

Traditional planters are usually made of a plastic material that has poor air permeability for roots. The roots need sufficient oxygen supply to promote the growth and respiration of flower seedlings, but the gas exchange capacity of traditional planters is limited and cannot meet the needs of the roots. In addition, traditional flower troughs are prone to deformation, cracking and other problems during use, which reduces the stability and service life of the flower troughs.

Specifically, the shortcomings of the existing technology are as follows:

(1) Poor air permeability: Traditional planters are usually made of a dense plastic material, which limits the permeability of oxygen, causing the roots to be unable to obtain sufficient oxygen supply. A lack of adequate oxygen affects the growth and respiration of flower seedlings, thereby reducing their health.

(2) Structural instability: Traditional flower troughs are prone to deformation, cracking and other problems during long-term use, which reduces the stability and service life of the flower troughs. The instability of the flower trough may cause the root system to twist, affecting the root development and overall growth of the flower seedlings.
