Embodiment 1

[0025] Example 1. Applied to reclamation of tidal flats in Taizhou, Zhejiang,

[0026] This example is a growth promoter applied to forest trees such as Cinnamomum camphora in coastal saline-alkali land with a water-soluble salt content of less than 2‰ in the soil. It is made of the following raw materials by weight:

[0027] Ferrous sulfate 45.3

[0028] Citric acid 27.2

[0029] Nitrogen 17.3

[0030] Phosphorus pentoxide 7.7

[0031] Boron fertilizer 3.5.

[0032] After the above-mentioned raw materials are uniformly mixed, it becomes a forest tree growth promoter for coastal saline-alkali land, and the application concentration is 2%.

[0033] After the accelerator is applied in furrow, compared with the conventional fertilizer, the greening rate of leaves can reach 50.3%, the height of the tree is increased by 10%, and the thickness of the stem is increased by 15%.

Embodiment 2

[0034] Embodiment 2. Applied to Shangyu, Zhejiang,

[0035] This embodiment is a growth promoter applied to forest trees such as Cinnamomum camphora with a water-soluble salt content of 2‰ to 4.5‰ in the soil, and it is made of the following raw materials by weight:

[0036] Ferrous sulfate 35.6

[0037] Citric acid 44.4

[0038] Nitrogen 12.5

[0039] Phosphorus pentoxide 5.3

[0040] Zinc fertilizer 2.2.

[0041] After the above-mentioned raw materials are uniformly mixed, it becomes a growth promoter of forest trees in coastal saline-alkali land, and the application concentration is 2%.

[0042] After furrow application of the accelerator, compared with conventional fertilizers, the greening rate of leaves can reach 62.5%, the height of the tree is increased by 8.4%, and the thickness of the stem is increased by 7%.

Embodiment 3

[0044] This example is a growth promoter applied to forest trees such as Cinnamomum camphora in coastal saline-alkali land with a water-soluble salt content of less than 2‰ in the soil.

[0045] Ferrous sulfate 30

[0046] Citric acid 20

[0047] Nitrogen 10

[0048] Phosphorus pentoxide 3

[0049] Molybdenum fertilizer 1.

[0050] After the above-mentioned raw materials are uniformly mixed, it becomes a forest tree growth promoter for coastal saline-alkali land, and the application concentration is 2%.

Abstract

The invention relates to a forest growth promoting agent used in alongshore alkaline land. The product can effectively prevent the yellows and bad growth for forest trees, dramatically increase soil effective nutrient and improve growing environment for forest trees, which is characterized by reasonable formulation, low cost, convenient utilization and good effect. The product can be used in alkaline land with water soluble salt content lower than 2%. or 2%.-4.5%.. Said promoter comprises following raw materials with their weight proportion being: ferric sulfate 30-60, citric acid 20-50, nitrogen 10-30, phosphoric acid anhydride 5-10, and trace fertilizer 1-5.

Description

Technical field [0001] The invention relates to a forest tree growth promoter used in coastal saline-alkali land. It is suitable for planting trees in coastal saline-alkali land. Background technique [0002] With the acceleration of economic development and urbanization, using the rich coastline and unique natural conditions, reclamation of land from the sea and construction of cities from the sea have become the dominant development direction in offshore areas. However, due to the salt content and pH value of the soil in the reclamation tidal flats However, most tree species, especially evergreen tree species, are acidic or neutral tree species. When planted in coastal saline-alkali land, there will be varying degrees of yellowing, poor growth, and even death, which severely restricts the speed and quality of ecological construction in coastal saline-alkali land. [0003] At present, there is no report on the research of forest growth promoters in coastal saline-alkali land. "Z...
