Problems solved by technology

One possible way to avoid this problem might be to apply oak specific fertilizers, i.e. only the nutrients that the oak can take up and use, and its competitors cannot take up and use or even inhibit growth.

Embodiment Construction

[0056] Fertilizers generally include macroelements such as nitrogen (N), phosphorus (P), potassium (K) and trace elements such as manganese (Mn). Manganese is a key trace element in the water splitting of plant photosynthesis system II, and manganese can activate various enzymes in plants. It has a positive effect on increasing the weight and promoting the growth of capillary roots.

[0057] Manganese element is Mn2+ form absorbed by plants from the soil. In the leaves of most plants, the content of manganese is 0.02mg g -1 (leaf dry weight) can meet the normal growth needs of plants. However, this concentration varies depending on the type of plant, the manganese content of the soil, and the pH value of the soil. For example, the surface runoff is alkaline and the manganese element undergoes a chemical reaction to reduce the manganese content in the soil, which in turn causes manganese deficiency in white oak. symptom.

[0058] Different plants have different requirements...

Abstract

The invention discloses a composition and method for promoting the growth of oak trees. Specifically, the method of the invention includes the steps of: applying a fertilizer composition to oak seedlings or the environment in which oak tree seedlings are planted, thereby promoting the growth of oak trees; and the fertilizer composition Products containing Mn salt and / or Mn(OH) 2 . The method of the invention can effectively and selectively increase the growth of the oak tree and / or increase the nutrient elements in the effective parts of the oak tree.

Description

technical field [0001] The invention relates to the field of plant seedling treatment, in particular to a composition and a method for promoting the growth of oak trees. Background technique [0002] Oak (Quercus sp.) is an important tree species in North American and Mediterranean forest ecosystems. However, oak woodland populations have been shrinking due to various problems with its regeneration, which has caused it to lose its dominance in the central hardwood regions of the eastern United States. Oak regrowth is one of the most important forest resource management issues today, and successful regrowth of oaks depends on whether there are enough competing oak seedlings to regrow on the forest floor before the canopy is disturbed. Oak seedlings typically have low first-year survival rates compared to their competitor, the shade-tolerant red maple. Because oak seedlings are fire-tolerant, while their competitors do not, prescribed planned forest fires have been employed ...
