Functional liquid fertilizer for orchard in salt-alkaline land and preparation method thereof

Abstract

The invention discloses a functional liquid fertilizer for an orchard in a salt-alkaline land and a preparation method thereof. The functional liquid fertilizer for the orchard in the salt-alkaline land is prepared from nutritional matters and biological active matters, wherein the nutritional matters comprise nitrogen, phosphor, potassium, boron and zinc; the biological active matters comprise glutamic acid, methionine, phenylalanine, levulinic acid, genistein and chitosan oligosaccharide. The functional liquid fertilizer has the advantages that the biochemical theory of fruit growth and development is used as the instruction concept; on the basis of mineral nutrients required by the fruit development, a biological stimulation factor for promoting forming of anthocyanin, a primer elicitorfor synthesizing of the anthocyanin and the like are added, so that the synthesizing of anthocyanin is obviously promoted, the fruit flavor is improved, the red fruit rate is obviously increased, andthe safety and high-efficiency in application are realized; the convenience in use is realized, the working period is shortened, the easiness in phytotoxicity is avoided, any toxic and side effect tohuman bodies and environments is avoided, and the like.

Description

technical field [0001] The invention relates to the fields of agricultural biotechnology and fertilizers, in particular to a functional liquid fertilizer for orchards in saline-alkaline areas and a preparation method thereof. Background technique [0002] Color is an important factor affecting the appearance quality of fruits. Usually, consumers like to choose fruits with correct appearance and bright color. How to promote fruit coloring and improve fruit quality is an important issue that growers are very concerned about. [0003] At present, the methods to promote fruit coloring mainly include: improving tree light conditions, controlling nitrogen fertilizer, increasing phosphorus and potassium fertilizer, bagging, picking leaves, transferring fruit, spreading reflective film and other measures; Traditional plant growth regulators such as acid, thiocyanate, gibberellin, and uniconazole to promote fruit coloring can have a good coloring effect. However, some substances ma...

Problems solved by technology

[0009] There are patents (Application No. 200410065334.3; 200510094293.5) reported that the use of levulinic acid (Levulinic acid, LA) or glutamic acid (Glutamate, Glu) improves the photosensitivity of the peel by changing the content of endogenous 5-aminolevulinic acid in the fruit, thereby promoting Fruit coloring can reduce the content of driptable acid and improve fruit quality; spray genistein (GNT) to promote the coloring of colored fruits such as apples, pears, peaches, plums, apricots, grapes, strawberries, etc.; there are data It is reported that natural brassinolide and jasmonate have achieved certain effects in grape coloring, and genistein can redden and color the fruit, but there are few plant growth regulators that are actually put into use, or the coloring effect is not good. Obviously, it is not easy to cause some side effects

The above method is only to apply a single substance to fruit coloring, and the content of active ingredients is low, lack of nutritional supplements, and the application effect is not significant
