Description

A kind of Plant antifreezer

Technical field

The present invention relates to a kind of Plant antifreezer, be specially adapted to the warming in landscape engineering large plant winter.Be mainly used in the preventing freeze in winter of the large plant of landscape engineering.

Background technology

When atmospheric temperature drops to below zero centigrade, some plants are endured cold lethal owing to not resisting severe cold, and other plants can be stood proudly in the world of ice and snow, full of life.This is because the freeze proof ability of different plant has the cause of significant difference.

Ornamental plant protection against cold and freezing conditions, just refers to how to tackle more than 0 DEG C damage to plants caused by sudden drop in temperature, the freeze injury of less than 0 DEG C, and early autumn, season late spring occur suddenly and the unexpected frostbite etc. occurred.It is antifreeze antifreeze with chemistry that protection against cold and freezing conditions comprises physics.At present main taked be antifreeze based on physics, chemistry is antifreeze is auxiliary.But it is mainly antifreeze based on physics.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of Plant antifreezer, is a kind of compound antifreezer, is mainly used in the preventing freeze in winter of the large plant of landscape engineering; Make to plant and produce certain cold tolerance.

For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions.

A kind of Plant antifreezer, compound sodium nitrophenolate 0.2-0.3%; Chitosan oligosaccharide 0.08-0.1%; Propane diols 2-3.5%; Glycerine 6-8%; Glucose 0.4-0.8%; Potassium dihydrogen phosphate 0.01-0.03%; Paclobutrazol 0.05-0.15%, brassin 0.01-0.05%, growth regulator 0.1 ~ 0.2%, all the other are mineral water.

Its each composition preferred and weight percent content are: compound sodium nitrophenolate 0.2%; Chitosan oligosaccharide 0.1%; Propane diols 2.5%; Glycerine 7%; Glucose 0.4%; Potassium dihydrogen phosphate 0.03%; Paclobutrazol 0.15%, brassin 0.05%, growth regulator 0.2%, all the other are mineral water.

Preferably, growth regulator is the basic element of cell division.

Each active ingredient is fully dissolved in mineral water by preparation method.

Its using method and consumption:

Carry out filling with root in 20-30 days: the trees of trunk diameter >=12cm are diluted 100 times and fill with root before late fall, frost came; The trees of below diameter <12cm are diluted 210 times and fill with root, set 800 milliliters for every.Filled with root once every 25 days later.Continuous 3 times.

Above-mentioned Plant antifreezer, when temperature reduces, can maintain the normal liquid crystalline phase of biomembrane in body; Trees are made to possess stability in membrane structure; Intracellular ice can be avoided, in case the brilliant destruction to film of stagnant ice.

The beneficial effect that the present invention reaches:

Plant antifreezer of the present invention belongs to natural medicine, nontoxic, harmless, free from environmental pollution, and its preparation method is simple, and effective antifreeze phase can reach 25-30 days.

Embodiment

Embodiment 1

Antifreezing effect experiment is carried out with the willow that Plant antifreezer of the present invention is less than below 10cm for trunk diameter.

Its each composition and weight percent content are: compound sodium nitrophenolate 0.2%; Chitosan oligosaccharide 0.1%; Propane diols 2.5%; Glycerine 7%; Glucose 0.4%; Potassium dihydrogen phosphate 0.03%; Paclobutrazol 0.15%, brassin 0.05%, the basic element of cell division 0.2%, all the other are mineral water.

Each active ingredient is fully dissolved in mineral water before using by preparation method.

Test method be late fall frost come to dilute 210 times with running water in first 20 days and fill with roots.Filled with root once every 25 days later.Continuous 3 times.Cover trunk with straw rope binding simultaneously.50 trees.

Reference examples only covers trunk with straw rope binding.50 trees.

Experimental result: reference examples has 3 to set part branch frost bittens, next year germinates average late 11 days of ratio Plant antifreezer.
