Abstract
The plant nutrient extract containing low-molecular chitin is formed from chitin, zinc salt and/or boron-containing compound, in which the weight percentage of zinc salt and boron-containing compound is 0.2-7, and the described chitin is a low-molecular chitin, its molecular formula is [C6H9O4NR]n, where R is R1=H or R2=COCH3, n is less than or equal to 40, nR1 is greater than or equal to 4 and less than or equal to 12, and nR2 is greater than or equal to 28 and less than or equal to 36. Said invention can make the weight of plant leaf and root system increase by 25% and 30%, can raise chitinase activity by 40%, make colouring index of apple increase by 80% and can raise yield of cucumber, ginger and carrot by 10-20%.
Description
The present invention relates to a kind of agricultural fertilizer or plant growth regulator.
Existing trace-element fertilizer zinc fertilizer is (such as ZnSO
4Or ZnEDTA) and boron fertilizer (such as H

7) when using separately the plant that lacks in zinc, the boron deficient soil all there is certain growth-promoting effect, but not enough remarkable, also have some side effects, for example local application too much or to some rich zinc or boron-rich soil may cause zinc or borism.There is the human polymer chitosan to make seed pelleting, because it is water insoluble, so when being applied to plant, also must add rare inorganic acid or organic acid, so just may causes the injury to crops or people and animals and environment.
The purpose of this invention is to provide a kind of nutrient for plants that contains low molecular chitosan, it can remedy the above-mentioned deficiency of prior art.
Nutrient for plants of the present invention is characterized in that it is made up of chitosan, zinc salt and/or boron-containing compound, and the weight percentage of zinc salt and boron-containing compound is 0.2～7.
Nutrient for plants of the present invention can make plant leaf and root system increase weight 25% and 30% respectively, makes the chitinase vigor strengthen 40%, and making apple colour index increases by 8%, makes cucumber, Da Jiang and Radix Dauci Sativae volume increase 10-20%.
Below by embodiment the present invention is described.
