Cutting seedling raising seedbed

Abstract

The invention relates to the plant propagation technology, and aims at providing a cutting seedling raising seedbed. The cutting seedling raising seedbed comprises a seedling pond and a PVC pipe B. The seedling pond is built on flat ground, PVC pipes A are embedded into the tops of the side walls of the seedling pond, the two ends of the PVC pipe B are inserted into the embedded PVC pipes A, the PVC pipe B forms an arched shed shape, the middle of the arched shed formed by the PVC pipe B is fixed through a cross rod in the length direction of the seedbed, and a spray pipe is fixed to the cross rod, plastic cloth is laid at the bottom of the seedling pond; a straw reactor is laid on the plastic cloth, an air pipe is laid between the plastic cloth and the straw reactor, the plastic cloth laid at the bottom of the seedling pond covers the straw reactor and is randomly punched, no-woven fabric is laid on the punched plastic cloth, and a cutting medium is laid on the non-woven fabric. According to the seedbed, cutting seedling rooting can be promoted, growth conditions of cutting seedlings can be guaranteed, and growth of the cutting seedlings is promoted.

Description

technical field [0001] The invention belongs to the field of plant propagation, and in particular relates to a cutting seedling raising seedbed. Background technique [0002] Cutting seedling raising technology is widely used in the field of seedlings and flower vegetative propagation, generally including hard branch cuttings and tender branch cuttings, and cutting carriers are divided into two types: seedbed type and container type. Compared with container-type cuttings, seedbed-type cuttings are widely used because they save manpower, space and cost. At present, the more commonly used cutting seedbeds are divided into above-ground type and underground type according to their height. The thickness is evenly laid in the bed groove to form a slotting bed. Cutting technology "one point for cutting, nine points for management". Management is the key to the survival of cuttings. At present, many researchers mainly study from the aspect of rooting agents, and there are few studi...

Problems solved by technology

The size of the reproduction coefficient is an important indicator for the preservation of plant resources, and it is also an important indicator for the rapid propagation of new and excellent varieties. Although the cutting rapid propagation technology of many units in the industry is very mature, and the survival rate has reached a high level, but the plant varieties are different, and a single cutting management The method cannot be applied to all varieties, the cutting equipment system has been established, and the corresponding maintenance conditions cannot be adjusted according to the needs of the plants during the management process

[0003] The currently commonly used cutting seedbeds have the following disadvantages: First, the cutting substrate is passively absorbed by watering or spraying to supplement water, fertilizer, and medicine. It is difficult to be precise during the operation. Stable within a suitable range, the fertilizer and drug content will also be lost with watering, reducing the persistence, thereby reducing the rooting rate of cuttings; second, because the bottom of the substrate in the bed directly contacts the ground or even lower than the ground, the substrate during the cutting process Excess water will continue to infiltrate the ground soil, causing the surface soil water content to reach saturation, no longer absorb the excess water infiltrating the substrate, and even infiltrate back into the substrate, even adding pebbles at the bottom of the substrate cannot block the water between the seedbed and the surface soil Exchange, resulting in long-term excessive water content of the substrate, poor air permeability, resulting in rotten cuttings

The third is that after the fungicide is added to the cutting matrix used, it is easy to lose with watering, the content is unstable, and the efficacy period is short, so it is difficult to achieve the ideal bactericidal effect. The cuttings are easily infected by germs, and one application cannot satisfy the whole The needs of the cutting cycle require regular replenishment, which is labor-intensive

4. In the closed space of the cutting area, the content of oxygen and carbon dioxide is low, and the air permeability of the substrate is poor. After the seedling cuttings survive, the supply of gas and fertilizer is insufficient, resulting in the death of the seedlings
