Description
Technical Field
The invention belongs to the technical field of plant cultivation, and particularly relates to a maintenance and cultivation method for false live seedlings and application thereof.
Background
At present, the phenomena of low seedling survival rate, poor growth condition, false survival of seedlings and the like commonly exist in gardens, and serious negative effects are caused on the garden greening effect. Particularly, false phenomena, wrong signals are released for nursing personnel, the best treatment opportunity is missed, and the nursery stock is difficult to be saved. The false survival phenomenon of the landscaping seedlings is caused by the fact that some seedlings grow branches by virtue of nutrients stored in the seedlings, when the germinated and branched seedlings cannot obtain water and nutrients supplied by a root system for a long time, and the nutrients stored in the seedlings are exhausted, so that the seedlings are dried and dead. When the false live phenomenon of the nursery stock occurs, effective measures must be taken in time to rescue the false live nursery stock and improve the survival rate of the nursery stock, thereby ensuring the landscaping effect.
CN106508601A discloses a tree transplanting method for improving survival rate, which comprises a tree cultivating step and a tree transplanting step; the tree cultivating step comprises: arranging a tree incubator, laying a water passing cushion block, and then laying a culture bottom layer on the water passing cushion block; arranging a baffle groove on the cultivation bottom layer, and filling nutrient soil on the cultivation bottom layer to obtain a first soil covering layer; planting trees; filling the coal cinder and loess mixture to obtain a second bedding layer; filling the plant cuttings and soil mixture to obtain a third bedding layer; filling plant ash to obtain a surface layer; covering the surface layer with rice straw; and (5) carrying out watering irrigation, wherein the soil humidity is kept at 65-78% by watering irrigation. The tree transplanting method for improving the survival rate can effectively improve the tree transplanting efficiency, but the survival rate of the transplanted tree still needs to be further improved.
CN107439291A discloses an oxygen-increasing cultivation method for seedlings, which achieves the effects of water retention, fertilizer retention, root strengthening, oxygen slow release promotion of root system development and the like by utilizing a mulching film, a porous matrix layer and an oxygen-increasing matrix layer in seedling cultivation holes, and realizes scientific application of water and fertilizer, reduces labor cost, makes the cultivated seedlings more robust and improves the transplanting survival rate by building water seepage pipes in each cultivation layer. However, the cultivation method only has the function of promoting the growth of the root system of the nursery stock, and has no function of maintaining the branches of the nursery stock.
CN108541505A discloses a method for planting trees, which comprises the following steps: nursery stock preparation, balanced pruning, digging and transporting, medicament treatment, planting, bottom watering, soil covering, soil moisture covering, binding and fixing and maintenance; through a scientific transplanting and planting method, the smoothness of the transplanting process is ensured, meanwhile, the nutrient soil and the medicament are added for treatment, the seedlings newly transplanted into the pits are promoted to rapidly grow lateral roots, the nutrient supply of the trees is increased, the seedlings rapidly return to a normal state, and finally the transplanting survival rate of the seedlings is improved through the method. However, the method is the same, and corresponding maintenance treatment is not carried out on the branches of the nursery stocks.
Based on the above researches, many researches are conducted on the transplanting method of the nursery stock, the survival rate of the nursery stock can be improved to a certain extent, but the survival rate still needs to be improved, and the maintenance of the branches of the false live nursery stock still needs to be further researched. Therefore, the maintenance and cultivation method for the false live seedlings is found, the seedling branches are maintained while the growth of the seedling root systems is promoted, the survival rate and the growth condition of the seedlings are improved better, and the method has important practical significance for the technical field of plant transplantation and cultivation.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a maintenance and cultivation method for false live seedlings and application thereof. The cultivation method is economical and effective, has no harm to the environment, can effectively improve the root growth environment, promote root growth, and moisturize and sterilize the branches and the trunks of the nursery stock, thereby reducing the pressure of the roots and improving the survival rate of the nursery stock.
In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the invention provides a maintenance and cultivation method for false live seedlings, which comprises a seedling root growth promotion step and a seedling branch maintenance step.
The seedling root system growth promoting step comprises the following steps: symmetrically digging from the side surface of the tree pit to the bottom of the root along the outer edge of the soil ball, then adding a rooting agent and an oxygen increasing agent around the tree pit for the first time, and adding the rooting agent again after 10-20 days.
The nursery stock branch maintenance step comprises the following steps: spraying a bark protective agent and a bactericide on the branches and trunks of the nursery stocks, and simultaneously carrying out light control treatment.
The bark protective agent comprises any one or the combination of at least two of alginic acid, dichlorphenoxyacetic acid and potassium nitrate. The combination of at least two of the above-mentioned materials can be the combination of alginic acid and dichlorophenoxyacetic acid or the combination of dichlorophenoxyacetic acid and potassium nitrate, etc., and any other combination mode can be selected, and therefore the details are not repeated.
The seedling root growth promoting step can effectively improve the root growth environment and promote the growth of the root by promoting the growth of the root of the false live seedlings and increasing oxygen in the soil. Meanwhile, the selected oxygenation agents have the functions of disinfection and sterilization, do not produce secondary pollution and are harmless to human bodies, animals, environment and the like. In addition, the nursery stock branch maintenance step inhibits the transpiration of the branches and leaves by controlling illumination and spraying a bactericide, and moisturizes and sterilizes the branches, thereby reducing the pressure of the roots. The bark protective agent can effectively prevent bark from cracking, damaging and falling off, ensure that the bark has normal transportation and conduction functions of conveying nutrients, water, organic substances and the like in plant life activities, simultaneously can protect trees from freezing damage and high-temperature dehydration, prevent disease and pest disasters, mechanical damage and the like, and improve the survival rate of the false-living seedlings after seedling transplantation.
It is noted that the method is economic and effective and has no harm to the environment by matching the seedling root system growth promotion step and the seedling branch maintenance step, can achieve the purpose of treating false live seedlings, obviously improves the survival rate of the seedlings, and has great practical significance for the field of plant cultivation.
