Description
Technical Field
The invention relates to the field of tree transplantation, in particular to a tree nutrient solution, a preparation method and application thereof.
Background
With the rapid development of ecological construction in China, the concept of ecological gardens is more and more emphasized. The trees are the most important components of gardens, and in the process of building gardens, gardeners pay more and more attention to the work of planting trees, transplanting big trees, introducing new varieties of trees and the like. In the current engineering construction, the phenomena of big tree transplantation and out-of-season plantation are increasing day by day, which brings more serious challenges to garden workers in the plantation and management of trees. How to improve the survival rate of big tree transplantation and out-of-season transplantation is an urgent problem to be solved.
At present, the main measure for improving the survival rate of trees is to use tree nutrient solution. However, the proportion of the common tree nutrient solution in the market is too balanced, the pertinence is weak, the price is higher, the common tree nutrient solution is more suitable for conventional maintenance, the more and more complex tree planting environment cannot be ensured, and particularly, the common tree nutrient solution for big tree transplantation and out-of-season transplantation is lacked.
Therefore, the present invention is to develop a nutrient solution for trees to solve the problem of survival of big trees and off-season transplanted trees.
Disclosure of Invention
The first purpose of the invention is to provide a tree nutrient solution, which can improve the survival rate of transplanted big trees and the anti-season transplanted trees and shorten the seedling revival period of the trees.
The second purpose of the invention is to provide a preparation method of the tree nutrient solution, which has the advantages of convenience, rapidness and convenience for scale production.
The third purpose of the invention is to provide the application of the tree nutrient solution in the large tree transplantation, the tree off-season transplantation or the large tree off-season transplantation.
In order to achieve the above purpose of the present invention, the following technical solutions are adopted:
a tree nutrient solution, each liter of which comprises 300-440 mg of monopotassium phosphate, 220-360 mg of calcium ammonium nitrate, 530-670 mg of potassium nitrate, 320-460 mg of ammonium phosphate, 10-8-10E-10 mol of auxin and 0-120 mg of magnesium sulfate.
The transplantation of the out-of-season transplanted trees and big trees can damage the root systems of the trees, so that the root systems have poor capability of absorbing water and nutrients, and the water of the leaf parts is evaporated, so that the trees which are just transplanted are withered and dead easily.
The nutrient solution can permeate into the interior of trees in an ultra-strong manner, effectively stimulate plant cells, accelerate the division of the cells, improve circulation, and ensure the comprehensive absorption and utilization of various nutrients by the trees, thereby promoting the survival of the plants. N, P, K element provides basic demand for plant growth, and improves the resistance of trees while ensuring the energy required by the growth of trees, which is more beneficial to the survival of the trees planted out of season. The growth factor content promotes the development and growth of plant root organs; the magnesium and the potassium are beneficial to the photosynthesis of trees, improve the resistance of plants and have better promotion effect on the growth of the plants. In conclusion, through the mutual matching of all the nutrient components, the tree nutrient solution can effectively improve the survival rate of big tree transplantation and out-of-season tree transplantation and shorten the seedling revival period of trees.
In some specific embodiments, each liter of the tree nutrient solution comprises 400-440 mg of monopotassium phosphate, 320-360 mg of calcium ammonium nitrate, 630-670 mg of potassium nitrate, 420-460 mg of ammonium phosphate, 10-9-10E-10 mol of auxin and 80-120 mg of magnesium sulfate.
In some specific embodiments, the tree nutrient solution comprises 420mg of monopotassium phosphate, 340mg of calcium ammonium nitrate, 650mg of potassium nitrate, 440mg of ammonium phosphate, 10E-10mol of auxin and 100mg of magnesium sulfate per liter of the tree nutrient solution.
The tree nutrient solution optimizes the content and the proportion of each component, the auxin concentration is 10E-10 mol/L, relevant researches show that the auxin has the effect of promoting the planting of roots, stems and buds, but the auxin with different concentrations has different promoting effects on the roots, the stems and the buds, the auxin with the concentration of 10E-10 mol/L is most suitable for promoting the growth of the roots, the auxin with the concentration lower than 10E-10 mol/L has obvious promoting effect on the stems and the buds, most roots are seriously injured when large trees and anti-season trees are transplanted, and therefore, the key for improving the survival rate of the trees and shortening the seedling recovering period is to promote the growth of the roots.
The addition of magnesium sulfate, because magnesium is an important element for forming a chlorophyll structure, if magnesium is not contained, chlorophyll cannot be generated, and light and effects cannot be generated. Photosynthesis, which is the main way plants convert light energy into chemical energy, does not grow without photosynthesis.
The content of N, P and K is closest to 7:5:21, and the content of P, K elements is improved while the content of N is ensured. The content of the N element is not the highest, which is greatly different from other nutrient solutions. Although N is an important component of cell composition and is an essential nutrient for plant growth, excessive N can cause rapid growth of plants and is not beneficial to seedling recovery of newly transplanted trees. The invention has moderate N content, and can provide basic energy for plants without over-stimulating the growth of the plants. The P element can promote the growth and development of plant roots, improve the cold resistance of plants and facilitate the survival of trees transplanted in winter. K is used as a main nutrient element of a plant body, has higher distribution amount in organs and tissues with active plant metabolism, and has great effect on enhancing the regulation of cells on environmental conditions. And K can enhance the tolerance of the plant to various adverse conditions, such as drought, low temperature, salt content, insect damage, lodging and the like. The content of K is improved, the moisture is effectively utilized by crops, the transpiration of the moisture is reduced, and the stress resistance of the crops is improved. The tree nutrient solution has sufficient N, P, K content and proper proportion, and is beneficial to survival and seedling recovery of big trees and transplanted trees according to practical libraries shown in experimental examples.
In some specific embodiments, the tree nutrient solution comprises 320mg of monopotassium phosphate, 240mg of calcium ammonium nitrate, 550mg of potassium nitrate, 340mg of ammonium phosphate and 10E-8mol of auxin per liter.
In some specific embodiments, the tree nutrient solution comprises 370mg of monopotassium phosphate, 290mg of calcium ammonium nitrate, 600mg of potassium nitrate, 390mg of ammonium phosphate, 10E-9mol of auxin and 50mg of magnesium sulfate per liter of the tree nutrient solution.
In some embodiments, the solvent of the tree nutrient solution is water, preferably mineral water. Wherein, the mineral water and distilled water contain certain minerals (Mg, Fe, Mn, Na, etc.) to promote plant growth.
The invention also provides a preparation method of the tree nutrient solution, which comprises the following steps: a. weighing calcium ammonium nitrate and ammonium phosphate, or calcium ammonium nitrate, ammonium phosphate and magnesium sulfate, and stirring until the calcium ammonium nitrate, the calcium ammonium phosphate and the magnesium sulfate are completely dissolved to prepare a mixed solution; b. weighing potassium nitrate, heating and stirring until the potassium nitrate is completely dissolved to obtain a potassium nitrate solution; c. weighing potassium dihydrogen phosphate, heating, stirring and dissolving to prepare potassium dihydrogen phosphate solution; d. and uniformly mixing the mixed solution, the potassium nitrate solution, the potassium dihydrogen phosphate solution and the auxin, and fixing the volume to obtain the tree nutrient solution.
