Abstract

The invention relates to a rescue reagent for rejuvenation of Pinus tabulaeformis and an application thereof. The rescue reagent for rejuvenation is prepared by mixing the following components: refined pyroligneous liquor, amino acid, peptidoglycan, potassium sulfate, sodium alpha-naphthyl acetate, ferrous sulphate, urea, and VC. The rescue reagent for rejuvenation has the advantages of environmental friendliness, simple technology, and low cost; during practical application, water can be added into the reagent for dilution, the dilution ratio is 3-10 times, and the solution is filled into an axial root part of a big tree.

[0021] Example 1 A Rejuvenation Rescue Reagent for Chinese Pine

[0022] (1) Preparation

[0023] According to the ratio shown in Table 1, take wood vinegar, amino acid, peptidoglycan, potassium sulfate, sodium naphthaleneacetate, ferrous sulfate, urea and VC, mix them evenly, put them into plastic containers, and prepare them for oil. Loose rejuvenation rescue reagent.

[0024] Table 1

[0025]

[0026] (2) Application

[0027] 1) Choose 3-4 year-old seedlings: In the northern spring from March to April, the temperature should be kept above 5°C for watering. The lateral roots are mainly watered, and the surface soil is loosened in the horizontal direction of Pinus tabulaeformis. Dilute the rejuvenation and rescue reagent by 5 times, every interval Water once every 10 days, irrigate the surface soil each time;

[0028] Select 20 3-4 year old seedlings and randomly divide them into 4 groups with 5 plants in each group. The blank group and the experimental group (using 1#, 2#, 3#, 4# rejuvenation rescue reagent), the results are shown in Table 2.

[0029] Table 2

[0030]

[0031] 2) Choose 5-6 year-old saplings: water the taproot in the northern winter from November to January. Before the temperature stably drops to 0°C, dig a depth of 30cm along the vertical direction of the taproot, dilute the rejuvenation and rescue reagent 3 times, and water each time. 10 liters, water once every 10 days, a total of 3 times.

[0032] Select 20 5-6 year-old tree seedlings affected by salt and randomly divide them into 4 groups with 5 plants in each group. The blank group and experimental group (using 1#, 2#, 3#, 4# rejuvenation rescue reagent), the results are shown in Table 3.

[0033] table 3

[0034]

[0035] It can be seen from Table 2 and Table 3 that the rejuvenation rescue agent of the present invention has a good rejuvenation effect on the salt-injured Pinus tabulaeformis, especially the No. 4 rejuvenation rescue agent, the control effect can reach 100%, and the Pinus tabulaeformis is completely rejuvenated.
