Description
Technical Field
The invention relates to the technical field of agricultural growth regulators, in particular to a plant growth regulator composition containing brassinolide, chlorin iron and cytokinin and application thereof.
Background
The plant growth regulator is extracted and synthesized artificially based on the structure, function and action principle of plant hormone, and can change the synthesis, transportation, metabolism and action of hormone in plant body to regulate plant growth and physiological function. Auxins, gibberellins, ethylene, cytokinins, abscisic acid, brassinolide, and the like have been found. The plant growth regulator can promote or inhibit the growth and development of plants at a lower concentration. Plant growth regulators have been used in crops, fruit trees and vegetables for a wide range of applications.
At present, the single use of many plant growth regulators cannot achieve the ideal effect, and the disadvantages of the single use of the plant growth regulators are as follows: the biological activity is single, the growth regulating effect is relatively low, the use amount (or use concentration) is large, and the growth regulating effect can be achieved only in a certain growth period of crops generally. Therefore, it is necessary to properly and rationally select and mix different plant growth regulators in order to overcome or avoid the side effects, thereby achieving the desired application effects, i.e., synergy, addition or induction, and avoiding antagonism.
Brassinolide, a novel green environment-friendly plant growth regulator, is treated by soaking seeds and spraying stems and leaves of brassinolide with proper concentration. Can promote the growth of vegetables, melons, fruits and other crops, improve the quality, increase the yield, and ensure bright color and thicker leaves. The tea leaf picking time can be advanced, and the melon and fruit can have higher sugar content, larger individual, higher yield and better storage stability. Is harmless to human and livestock, and has safe and effective dosage when used normally. The natural brassin can be widely applied to various economic crops, can increase the yield by 5-10% and can reach 30% higher, obviously improve the quality, increase the sugar content and the weight of fruits and increase the gorgeous crops. Meanwhile, the drought resistance and the cold resistance of crops can be improved, and the symptoms of plant diseases and insect pests, phytotoxicity, fertilizer damage and freezing damage of the crops can be relieved.
The chlorin iron (III) chelate is prepared by chelating chlorin iron (III) chelate with pyropheophorbide, purpurin and chlorin as main ligands and different acid radicals or hydroxide radicals as axial ligands (X) and transition metal ferric ions. The plant growth regulator is safe and nontoxic and is not easy to accumulate residues; the activity is strong, and the effect is good; can improve the chlorophyll content of plants, promote rooting, improve germination rate, enhance stress resistance and increase yield.
Benzylaminopurine is high-activity cytokinin, has high activity, can increase chlorophyll, improve photosynthetic efficiency, effectively promote cell division and differentiation of plants, promote flower bud differentiation, accelerate growth and development, strengthen plants, strengthen fruits and expand fruits, and can improve yield.
Adenine is one of cytokinins. The plant growth regulator is prepared by pure biological fermentation, is mainly secreted and conducted to other parts by a root tip, stimulates cell division, promotes chlorophyll formation, and prevents premature senility and fruit shedding. Promoting photosynthesis and protein synthesis, and promoting flower bud differentiation and formation. And has good control effect on tomato, cucumber and tobacco virus diseases. The application range is grain, cotton, oil, vegetables, melons and fruits, medicinal materials, tobacco and the like.
Hydroxyalkenyladenine is one of cytokinins. Can stimulate plant cell division, promote chlorophyll formation, accelerate plant metabolism and protein synthesis, thereby achieving the purposes of rapidly increasing organism, promoting crops to be mature and high yield, and improving the disease resistance, ageing resistance and cold resistance of plants.
Furfuryl amino purine, one of cytokinins. The 1 st cytokinin discovered by human beings is a substance capable of promoting the division and differentiation of plant cells, is widely present in seaweed and most of plant bodies, belongs to an endogenous (natural) plant growth regulator which is produced by the plant bodies and has the function of regulating the growth of plants, and mainly has the function of promoting the division, differentiation and growth of the cells; inducing the callus to grow buds and removing the apical dominance; breaking dormancy of lateral buds and promoting seed germination; also has the functions of delaying the aging of leaves and cut flowers in vitro; inducing bud differentiation and development and increasing stomatal aperture; regulating transport of nutrients; promoting fructification and the like.
Citrus (Citrus reticulata Blanco) is a generic name of Citrus, Citrus reticulata, Citrus aurantium, Citrus grandis, and Poncirus trifoliata. China is one of the important native areas of citrus, the citrus resources are rich, the excellent varieties are various, the cultivation history is more than 4000 years, and the citrus becomes a precious fruit for human beings through long-term cultivation and selection. The flowering period of the citrus is generally 4-5 months, and the fruit period is 10-12 months. In recent years, due to the factors of various environmental problems such as global warming, haze and the like, the citrus has a lot of obstacles and troubles in the planting process, so that the effective measures adopted to protect flowers and fruits of the citrus become links which need to be broken by continuous efforts of agricultural workers.
Flower and fruit retention is an important means for improving the fruit setting rate of the citrus in the stable yield load capacity range. The purpose of flower and fruit retention is to improve the fruit setting rate, and the fruit setting rate is an important factor influencing the yield of the citrus. Therefore, the flower and fruit dropping is reduced by implementing the flower and fruit retention measures, the fruit setting rate is improved, and particularly the fruit setting rate is improved in the years with less flowers, so that the method is a key link for obtaining high yield of the citrus. The natural fruit setting rate of the citrus is generally low, and the increase of the weight of a single fruit is limited by the inheritance of varieties. Through continuous practice, the fact proves that artificial reasonable measures are continuously taken according to the natural growth rule of the oranges and the change factors of the oranges, so that the flowers and the fruits can be effectively preserved, and the loss is reduced.
At present, the conventional treatment technology for flower and fruit retention in actual production comprises the steps of improving the storage nutrition level of trees, properly controlling the vegetative growth, ensuring good pollination conditions, improving the environmental conditions, applying growth regulators and trace elements and the like. However, the existing efficient and cost-effective ternary plant growth regulator for flower and fruit retention is not common, so that the formula of the novel ternary plant growth regulator for flower and fruit retention of citrus becomes one of the hot development fields.
The above background disclosure is only for the purpose of assisting understanding of the inventive concept and technical solutions of the present invention, and it is not necessarily prior art to the present patent application, and should not be used for evaluating the novelty and inventive step of the present application in the case that there is no clear evidence that the above content is disclosed at the filing date of the present patent application.
