Description

Technical Field

[0001] This invention relates to the field of seedling cultivation, and more specifically to a method for planting seedlings in landscape engineering. Background Technology

[0002] The techniques and methods of seedling planting are widely used in forestry and landscaping. Currently, in order to shorten the construction period, the existing landscaping plants are usually planted by digging planting pits directly in the soil, placing the seedlings in the planting pits, backfilling the soil, compacting it, watering and fertilizing the seedlings, and then hanging nutrient solution upside down for infusion.

[0003] However, while planting garden plants using the above method is relatively simple and convenient in the early stages, the subsequent infusion and maintenance operations are troublesome, and the nutrients in the fertilizer and nutrient solution are difficult for the trees to absorb. This makes it difficult for the trees to absorb enough nutrients for their growth, which can affect the growth rate of the trees and may even affect their survival rate. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a method for planting seedlings in landscaping projects, which improves the adsorption of fertilizer or nutrients in the planting soil by the roots of the seedlings.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for planting saplings in a landscaping project includes the following steps:

[0007] S1: Seedling selection: Select seedlings with relatively straight trunks, free from pests and diseases, well-developed root systems, and robust trees;

[0008] S2: Seedling pretreatment: Place the roots of the seedlings to be planted into the rooting treatment solution and soak them at room temperature for 1-2 hours to obtain pretreated seedlings;

[0009] S3: Preparation of planting site: In early March, the soil on the land to be planted should be deeply tilled to a depth of 35-45 cm, the soil should be loose and not waterlogged, the soil, organic fertilizer and biomass solution should be mixed evenly, and the soil on the ridge should be broken up and leveled. Among them, 0.2-0.8 kg of biomass solution and 6-8 kg of organic fertilizer should be added to each square meter of soil.

[0010] S4: Transplanting of seedlings: From late March to early April, transplant the pretreated seedlings onto the raised beds and backfill with soil.

[0011] S5: Post-planting management of seedlings: Keep the soil moist, remove weeds frequently, water regularly according to the growth of the seedlings, and spray an appropriate amount of water on the canopy periodically.

[0012] Preferably, before the seedlings are planted, the crowns of the seedlings are pruned, retaining the main branches and good branches, and removing small side branches and miscellaneous branches.

[0013] Preferably, the rooting treatment solution comprises the following components: 10-20 parts modified corn starch, 6-8 parts magnesium sulfate, 8-10 parts copper sulfate, 6-10 parts potassium nitrate, 3-5 parts calcium nitrate, 3-5 parts naphthaleneacetic acid, and 100-120 parts deionized water.

[0014] Preferably, the rooting treatment solution is prepared by mixing modified corn starch, magnesium sulfate, copper sulfate, potassium nitrate, calcium nitrate, naphthaleneacetic acid, and deionized water, and stirring until homogeneous.

[0015] Preferably, the modified corn starch is prepared by: stirring corn starch, α-amylase, saccharifying enzyme and a disodium hydrogen phosphate / citric acid buffer solution with pH=4-5 at 50-60℃ for 10-12h, then adding a 30% sodium hydroxide solution to terminate the reaction, filtering, and drying to obtain modified corn starch.

[0016] Preferably, the weight ratio of corn starch, α-amylase, saccharifying enzyme, disodium hydrogen phosphate / citric acid buffer solution and sodium hydroxide solution is 90:1:5:10:1.

[0017] Preferably, the biomass solution comprises the following components: 10-20 parts of 1-butyl-3-methylimidazolium dihydrogen phosphate, 10-20 parts of biomass, 60-80 parts of dimethyl sulfoxide, and 5-10 parts of modified corn starch.

[0018] Preferably, the preparation method of the biomass solution is as follows: 1-butyl-3-methylimidazolium dihydrogen phosphate, biomass, dimethyl sulfoxide and modified corn starch are mixed and stirred evenly.

[0019] The modified starch of this invention possesses a rich porous structure, generating greater adsorption force through its recessed pores. This adsorption and protection of active substances such as naphthaleneacetic acid (NAA) is achieved. Furthermore, its large specific surface area allows NAA and other active substances to diffuse to the root surface. Combined with its strong adsorption capacity, this prevents the adsorbed NAA and other active substances from decomposing due to external pollutants or other influencing factors during the early stages of planting, thus achieving protection and slow release of active substances. Simultaneously, this invention decomposes biomass using ionic liquids and achieves layered coating of biomass and modified starch in an organic solvent, increasing the number of active sites and the spacing between coating layers. After planting, mixing with soil and organic fertilizer allows the small molecules from the decomposed biomass to be evenly and extensively propagated into the soil. Subsequent watering management enhances the fluidity and activity of organic nutrients and other growth-required substances, improving absorption rates. Detailed Implementation
