Description

Technical Field

[0001] The invention relates to the field of seedling planting, and in particular to a method for planting seedlings in a garden project. Background Art

[0002] The technology and methods of seedling planting are widely used in forestry and gardening work. At present, in order to shorten the construction period, the existing garden plant planting usually involves directly digging planting holes in the soil, placing the seedlings in the planting holes, backfilling the soil, compacting it, watering and fertilizing the seedlings, and then hanging nutrient solution upside down for infusion.

[0003] However, although the initial planting is relatively simple and convenient when using the above method to plant garden plants, the subsequent infusion and maintenance operations are troublesome, and the nutrients in the fertilizer and nutrient solution are difficult to be absorbed by the trees, which makes it easy for the trees to absorb enough nutrients for their growth, making the growth rate of the trees easily affected, and may even affect the survival rate of the trees. Summary of the invention

[0004] In view of this, the object of the present invention is to provide a method for planting seedlings in garden engineering, so as to improve the adsorption of fertilizer or planting soil nutrients by the roots of the seedlings.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A method for planting seedlings for gardening engineering comprises the following steps: S1: Seedling selection: Select seedlings with straight trunks, no pests and diseases, well-developed root systems, and strong trees; 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; S3: Preparation of planting site: In early March, the soil is turned 35-45 cm deep on the land to be planted. The soil is loose and water-free. The soil, organic fertilizer and biomass solution are mixed evenly. The soil on the surface of the ridge is raked and leveled. 0.2-0.8 kg of biomass solution is added to every 1 square meter of soil, and 6-8 kg of organic fertilizer is added to every 1 square meter of soil. S4: Planting of seedlings: Plant the pre-treated seedlings on the bed surface and backfill the soil from late March to early April; S5: Management after seedling planting: Keep the soil moist, remove weeds frequently, water regularly according to the growth of seedlings, and spray an appropriate amount of water on the crown regularly.

[0006] Preferably, before the seedlings are planted, the crowns of the seedlings are pruned to retain the main branches and good branches and remove small side branches and miscellaneous branches.

[0007] Preferably, the rooting treatment solution comprises the following components: 10-20 parts of modified corn starch, 6-8 parts of magnesium sulfate, 8-10 parts of copper sulfate, 6-10 parts of potassium nitrate, 3-5 parts of calcium nitrate, 3-5 parts of naphthylacetic acid and 100-120 parts of deionized water.

[0008] Preferably, the rooting treatment solution is prepared by mixing modified corn starch, magnesium sulfate, copper sulfate, potassium nitrate, calcium nitrate, naphthylacetic acid and deionized water, and stirring evenly.

[0009] Preferably, the preparation method of the modified corn starch is specifically as follows: corn starch, α-amylase, saccharifying enzyme and disodium hydrogen phosphate / citric acid buffer solution with a pH of 4-5 are added, stirred at 50-60° C. for 10-12 hours, and then a 30% by mass sodium hydroxide solution is added to terminate the reaction, filtered, and dried to obtain the modified corn starch.

[0010] Preferably, the weight ratio of the corn starch, α-amylase, saccharifying enzyme, disodium hydrogen phosphate / citric acid buffer solution and sodium hydroxide solution is 90:1:5:10:1.

[0011] Preferably, the biomass solution comprises the following components: 10-20 parts of 1-butyl-3-methylimidazole dihydrogen phosphate, 10-20 parts of biomass, 60-80 parts of dimethyl sulfoxide and 5-10 parts of modified corn starch.

[0012] Preferably, the preparation method of the biomass solution is specifically: mixing 1-butyl-3-methylimidazole dihydrogen phosphate, biomass, dimethyl sulfoxide and modified corn starch, and stirring evenly.

[0013] Modified starch of the present invention has abundant pore structure, produces greater adsorption force by the hole of depression, thus adsorbs and protects active substances such as naphthaleneacetic acid, in addition, it has larger specific surface area, so that active substances such as naphthaleneacetic acid are adsorbed and diffused to the root surface, combined with powerful adsorption capacity, it is avoided that active substances such as adsorbed naphthaleneacetic acid are decomposed by external pollutants or other influencing factors in the early stage of planting, so as to realize the protection and slow release of active substances. Meanwhile, the present invention decomposes biomass by ionic liquid, and realizes the layered coating of biomass and modified starch in organic solvent, increases active site and coating layer spacing, and after planting, by mixing with soil and organic fertilizer, small molecules after organic fertilizer and biomass decomposition can be cut into soil uniformly over a large area, with subsequent watering management, improve the mobility and activity of growth demand substances such as organic nutrients, and improve absorptivity.
