Special multifunctional foliar fertilizer for oil-tea trees, and preparation method and applications thereof

Abstract

The invention belongs to the field of foliar fertilizer, and relates to a special multifunctional foliar fertilizer for oil-tea trees. The special multifunctional foliar fertilizer for oil-tea trees comprises the following ingredients in parts by weight: 5-10 parts of urea, 5-8 parts of potassium dihydrogen phosphate, 3-4 parts of boric acid, 3-4 parts of magnesium chloride, 5-6 parts of calcium nitrate, 4-5 parts of glucose, 0.1-0.5 part of gibberellin, 0.5-1 part of abscisic acid, 3-5 parts of amino acid chelate, and 2-3 parts of surfactant. According to the foliage fertilization principle and aiming at the characteristics that the wax and cuticle on oil tea leaves are thick and the demand on nutrients is large and by utilizing and reasonably proportioning the main active ingredients of mineral elements, hormones, amino acid chelate, surfactant and the like, the foliar fertilizer can be effectively absorbed by the oil tea trees, and has multiple effects of promoting the seedling survival, improving the growth and fruit bearing and cultivation resilience and the like. According to the special multifunctional foliar fertilizer for oil-tea trees, the production technology of oil tea can be effectively simplified, the production cost of oil tea can be lowered, and the special multifunctional foliar fertilizer for oil-tea trees has wide application prospects.

Description

technical field [0001] The invention belongs to the field of foliar fertilizer, and in particular relates to a foliar fertilizer composed of various components, its preparation method and application. Background technique [0002] At present, the total area of ​​Camellia oleifera cultivation in the country is 3.67×10 6 hm 2 , mainly distributed in 14 provinces (autonomous regions, municipalities) in southern my country, of which Hunan, Jiangxi and Guangxi are the most. At present, the nutrient management of camellia oleifera faces the following problems: first, there are many dormant buds in the grafted seedlings of camellia oleifera, resulting in inconsistent growth of seedlings, complicated water and fertilizer management in the later stage, and poor growth of seedlings; As a result, the survival rate of seedlings is not high; the third is that Camellia oleifera fruit has a long growth period and a large demand for nutrients, and it is difficult to meet the needs of grow...

AI Technical Summary

Problems solved by technology

At present, the nutrient management of camellia oleifera faces the following problems: first, there are many dormant buds in the grafted seedlings of camellia oleifera, resulting in inconsistent growth of seedlings, complicated water and fertilizer management in the later stage, and poor growth of seedlings; As a result, the survival rate of seedlings is not high; the third is that Camellia oleifera fruit has a long growth period and a large demand for nutrients, and it is difficult to meet the needs of growth and firmness through soil fertilization alone. It is reported that in summer and autumn, when the fruit expands and the oil is transformed, there is a drought (commonly known as "dried fruit in July, dry oil in August"). The drought caused a reduction of more than 30% in the production of camellia oleifera, and in severe cases, it may even fail

[0008] The current camellia oleifera flour fertilizer is mainly used to increase the fruit setting rate of camellia oleifera, or it can only be used at the seedling stage, and it does not have the characteristics of being simple, practical and widely used.

At the same time, according to the characteristics that the surface wax and cuticle of the camellia oleifera are thicker, and the nutrients of topdressing outside the root (spraying foliar fertilizer) are not easy to absorb, a special multifunctional foliar fertilizer was developed in a targeted manner, resulting in insignificant application effect
