Description

Biological dormancy breaking agent

Technical Field

The invention relates to the field of biofertilizer, in particular to a biological dormancy breaking agent.

Background

The common dormancy breaking agent mainly comprises lime nitrogen and cyanamide, but the lime nitrogen and the cyanamide are finally used as effective substances. The action mechanism of cyanamide is as follows: the growth inhibitor ABA (abscisic acid) generated during the dormancy of cherry trees is mainly promoted to degrade in advance, the biological effect of low-temperature cold-demand quantity is replaced to a certain extent (theoretically, 20% of cold-demand quantity can be replaced), the cherry is promoted to sprout, bloom and bear fruits in advance, and the growth inhibitor ABA has a special effect on crops such as cherries and the like planted in subtropical regions lacking winter cold regions and greenhouses, and is widely applied to cherry planting in recent years.

The cyanamide product is a great help for breaking dormancy and early ripening of the cherries in the use process of the cherries, but has a plurality of problems. Such as: stimulating the rapid development of leaf buds to cause the imbalance of vegetative growth and reproductive growth, and generating a great amount of fruit shrinkage phenomenon in the hard core period; the branches grow too fast to grow in vain, and the formation of the buds in the second year is directly influenced; after the newly planted trees and weak trees use cyanamide, the normal development of the trees is inhibited, so that the yield is directly reduced; after the normal fruiting tree uses cyanamide continuously for several years, the new growth of the young trees is directly inhibited, and the tree vigor is weakened; the direct death of the buds caused by the spraying of the cyanamide after the buds are not completely developed (the flower receptacle is small and is shrunken), the yield is seriously influenced, the trees which are sprayed with the cyanamide seem to bloom more regularly, but the appearance of regular flowering is at the expense of the buds which are not fully developed, and the yield is directly reduced. Meanwhile, cyanamide often has adverse reactions to human bodies, nausea, vomiting and serious coma in use, and has certain destructive effect on the environment.

Therefore, the development of a novel safe and efficient dormancy breaking agent product is urgent for the healthy and sustainable development of the cherry industry.

Detailed Description

In autumn, a plant growth inhibitor, namely abscisic acid (ABA), begins to be naturally synthesized by a cherry tree body along with the gradual decrease of the environmental temperature every year, when the abscisic acid is accumulated to a certain equivalent amount in the tree body, the growth and development of the cherry tree in autumn is naturally stopped, the synthesized nutrition of leaves begins to flow back, most of the nutrition is stored in branches and trunks, and part of the nutrition flows back to the roots to promote the secondary development of the roots in autumn. The peak period of abscisic acid synthesis is from late autumn to early defoliation, and when a large amount of abscisic acid is accumulated in the tree body and the ambient temperature is reduced to be below 7.2 ℃, the cherry trees start to enter a natural dormancy stage.

After the cherry trees enter the dormancy stage, the dormancy can be released only through a certain low temperature, the cold demand quantity of different cherry varieties is greatly different, and the cold demand quantity of common cherry varieties in the temperature range of 0-7.2 ℃ is 800-1400 h. The dormancy process is not only the natural degradation process of abscisic acid, but also the deep biochemical reaction process of the stored nutrition of the tree body, and the cherry trees can begin to germinate when the external temperature is proper after the requirement of cold quantity is met. After the cyanamide is used, although the cyanamide can quickly supplement cold energy required to realize the degradation of abscisic acid, the biochemical reaction in the tree body is not fully completed due to insufficient dormancy period, so that the tree body cannot quickly provide sufficient nutrition for the developing buds after the temperature is raised, the developing buds (small flower receptacle and shriveled) cannot develop and die, only the flower buds with very full buds (the development of the flower receptacle is completed) can continue to develop, and the yield of cherries is directly reduced.

In the invention, high-energy nutrition is rapidly supplied to trees through high-energy active microorganisms (ATP, SOD, light and bacteria, bacillus subtilis, green yeast and bifidobacterium), amino acid and glucose, wherein ATP (adenosine triphosphate) is a high-energy phosphate compound commonly existing in various living cells. ATP hydrolysis can release a large amount of energy, and a large amount of chemical energy in ATP molecules is stored in high-energy phosphate bonds. Part of ATPase is an internal membrane protein, can be anchored on a biological membrane, and can move on the membrane; these ATPases are also known as transmembrane ATPases. Transmembrane atpases can import many substances required for metabolism into cells and export poisons, metabolic wastes, and other substances that may impede cellular processes.

SOD (superoxide dismutase) is a kind of metalloenzyme, contains two ions of copper and zinc, and is used for catalyzing the superoxide anion related to antibody to be changed into hydrogen peroxide, then is decomposed by the hydrogen peroxide to protect organism from being influenced by the superoxide anion, is an active substance originated from life body, can eliminate harmful substance produced by organism in the process of metabolism, and is a novel antioxidant enzyme.

ATP and SOD can freely enter and exit the interior of the plant cell wall, ATP can be degraded into ADP by virtue of the powerful degradation function of microbial strains, particularly the powerful degradation function of photosynthetic bacteria, the effect of freely entering cells can be realized, high-energy nutrition is further transmitted to the cells to be absorbed, and metabolic wastes (including abscisic acid and the like) generated in the dormancy process are transmitted out of the cell wall to be rapidly decomposed, so that the micro-ecological environment in plant cell tissues is purified while the plant cells in the dormancy state are activated, and the tree body is promoted to rapidly break the dormancy state and recover the growth situation.
