9kg of soybean meal, 18kg of tea seed cake, 9kg of rapeseed meal, 8kg of amino acid, 0.8kg of zinc sulfate, 0.3kg of copper sulfate, 0.8kg of ferrous sulfate, 0.8kg of borax, 0.08kg of 5-nitroguaiacol sodium, 0.8kg of selenium-enriched yeast, 0.08kg of alpha-sodium naphthalene acetate and 0.07kg of citric acid.

The soil leavening agent in the embodiment is prepared from the following raw materials in parts by mass: 12kg of crushed corn straw, 27kg of crushed cotton straw, 13kg of crushed wheat straw, 21kg of edible fungus residue and 7kg of zeolite powder.

The nutrient solution in this example comprises: liquid A, liquid B and liquid C; wherein the solution A comprises: 50g of potassium nitrate; the liquid B comprises: 30g of monopotassium phosphate, 10g of magnesium sulfate and 50g of ammonium sulfate; the solution C comprises: 20g of iron compound, 15g of manganese sulfate, 10g of zinc sulfate and 40g of ammonium molybdate.

In the embodiment, the fly ash clinker is prepared from the following components by a calcination process; the mass of the fly ash, the mass of the calcium oxide, the mass of the sodium carbonate and the mass of the potassium carbonate are respectively 0.5kg, 4kg, 0.1kg and 0.15 kg; wherein: the sodium carbonate and the potassium carbonate are both prepared into aqueous solution or standard solution for use.

Example 8

The difference from example 7 is: in the embodiment, the fly ash clinker is prepared from the following components by a calcination process; the mass of the fly ash, the mass of the calcium carbonate, the mass of the sodium carbonate and the mass of the potassium carbonate are respectively 0.5kg, 0.6kg, 0.1kg and 0.15 kg; wherein: the sodium carbonate and the potassium carbonate are both prepared into aqueous solution or standard solution for use.

Example 9

The difference from example 7 is: the soil mineral conditioner in the embodiment comprises humic acid, humus soil and cured pig manure; the mass of the humus soil, the mass of the humic acid and the mass of the cured pig manure are respectively 8kg, 2kg and 12 kg.

In examples 1-9 and comparative example 1, the same kind of seedlings with the same diameter at breast height were selected and transplanted and maintained at the same time, 20 seedlings were used in each example, the same planting place after transplanting was obtained, only other steps or substances were added, the survival rate of the seedlings was counted 2 years after transplanting, and the results are shown in table 1.

TABLE 1

As can be seen from Table 1, improved soil is filled in the planting holes and consists of peat soil and special fertilizer for nursery stocks according to the mass ratio of 1: 1, specifically: the mass of the peat soil and the special fertilizer for the nursery stocks is 10 kg; the survival rate is obviously improved, and the survival rate after transplanting is obviously improved by adding the soil water-retaining agent, applying the anti-pest fertilizer, the soil leavening agent and the nutrient solution for promoting growth.

Finally, it should be noted that: the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
