Abstract

The invention discloses a tombarthite resisting drought water-loss reducer comprising sodium polyacrylate, boracic acid, zinc sulphate, manganese sulphate, aquadrate, monopotassium phosphate, lanthanum citrate, cerium citrate, neodymium acetate, edible gelatine and acacia gum. The invention can be used for the plant production in arid or semi-arid area, which can stimulate the growth of plant without lowering absorbent and water retentiveness property.

Description

The rare earth anti-drought water-retaining agent
One, affiliated technical field:
The present invention relates to a kind of multifunctional rare-earth water-holding agent that is used for arid, semiarid zone plant husbandry, belong to the plant husbandry field.
Two, background technology:
The polymer water-holding agent is applied in developed country, and output and application area have all obtained increase.Domestic also at application macromolecule water uptake water-keeping material, use area also in continuous increase.But at present used macromolecule water absorbent material exists following shortcoming: (1) has the water-absorbing-retaining function merely, act on single, and unstable, general user's acceptance of being unwilling; (2) though other material (as urea, potassium primary phosphate etc.) that has been mixed that has has reduced the water-absorbing-retaining performance.
Three, Fa Ming purpose:
The purpose of this invention is to provide a kind of rare earth anti-drought water-retaining agent, promptly do not reduce the water-absorbing-retaining performance, have the function that stimulating plant grows again.The surviving rate and the storage rate of planting trees and grass for the arid area are significantly improved.This invented technology compound method is simple, easy to use, of many uses, with low cost.
Four, Fa Ming content:
Rare earth anti-drought water-retaining agent of the present invention is realized by following preparation of raw material:
Sodium polyacrylate is that 60-80%, boric acid are that 0.5-1%, zinc sulfate are that 1-2%, manganous sulfate are that 0.5-1%, urea are that 4-10%, potassium primary phosphate are that 3-10%, citric acid lanthanum are that 2-5%, cerium citrate are 1-3%, acetic acid neodymium 1-2%, edible Gelatinum oxhide 1-3%, gum arabic 1-3% preparation.Suction multiple>300 times, pH value is 6.5-7.5.
Five, Fa Ming effect:
Rare earth anti-drought water-retaining agent of the present invention is multiplied forest, herbage, farm crop surviving rate under drought condition, and the plant strain growth stalwartness is well established and vigorously developing.Strengthen the control that plant cell membrane exosmoses to ionogen, can improve plant, promote plant metabolism adverse environment resistance (as arid, low temperature, saline and alkaline etc.), the enhancing physiologically active, quality index and effect are better than common water-absorbing material.
Six, the brief description of process flow sheet of the present invention:
This figure is a technological process block-diagram.
1, edible Gelatinum oxhide, the gum arabic that weighs up earlier is dissolved in 85 ℃ of hot water, again urea, potassium primary phosphate, boric acid, zinc sulfate, manganous sulfate joined dissolving fully;
2, citric acid lanthanum, cerium citrate, acetic acid neodymium are added under stirring condition successively in the solution of above-mentioned (1) until dissolving;
3, with above-mentioned solution crushing screening to 20 order after 65-90 ℃ of oven dry;
4, same grinding and sieving to 20 order of sodium polyacrylate and above-mentioned crushed material are puddled evenly;
5, accurately weighing, packing are the finished product warehouse-in.
Seven, most preferred embodiment of the present invention:
Embodiment 1:(sees Table 1)
