preparation example Construction

[0024] Another object of the present invention is to provide a kind of preparation method of saline-alkali land soil conditioner, it may further comprise the steps:

[0025] (1) Raw material preparation: Weigh the above-mentioned raw materials according to the mass percentage for later use;

[0026] (2) Heating: Take part of the water in step (1) and add it to the reactor, and heat the reactor to make the water temperature reach 50-60°C;

[0027] (3) Dissolution: Add the fatty alcohol polyoxyethylene ether in step (1) into the reaction kettle and fully dissolve it;

[0028] (4) Mixing: Add the polymaleic acid acrylic acid copolymer, polyacrylic acid sodium salt and citric acid in the step (1) into the reaction kettle in order, and stir to fully dissolve them;

[0029] (5) Add water: Add the remaining water in step (2) into the reaction kettle and mix it evenly;

[0030] (6) Cooling: Cool the mixed solution in the reactor to 20°C;

[0031] (7) Inspection of canning: Sampling...

Embodiment 1

[0033] The experimental site is the newly reclaimed saline-alkali land in Hami, Xinjiang. The crop is cotton, and drip irrigation is used to press salt. The test site is three pieces of saline-alkali land with an area of ​​1 mu, and 20 kg of saline-alkali soil amendment is applied to 1 mu of saline-alkali land; The test method is that the saline-alkali land soil improver of the present invention will be mixed with water for 5 times in different treatments, and added to the fertilizer drip tank respectively, then the valve is opened, and the dripping water is evenly dripped into the test field, and the water is dripped continuously for 12 hours. Soil augers were used to take soil at a depth of 30 cm. Soil samples were taken before drip application and after one week of water cutoff, and sent to the laboratory for indoor salt analysis. The soil test results are shown in Table 1.

[0034] As can be seen from the analysis of soil test results, the desalination rate of processing 1...

Embodiment 2

[0039] The test site is the saline-alkali land of an agricultural science institute in southern Xinjiang. The previous crop in the saline-alkali land was cotton, but due to the heavy salinity, no seedlings appeared year after year, and the surface soil was efflorescent. Three treatments were set up in the experiment, each with an area of ​​134m 2 , a total of 402 m 2 . Get soil assay before spraying, set concentration and consumption of the present invention according to assay result. Treat 1 mu with 20 kg of saline-alkali soil improver; treat 2 mu with 10 kg of saline-alkali soil improver; treat 3 as a control and apply water. The test method is to first build ridges respectively in three test fields so that the furrow irrigation water does not flow out, and then the present invention is placed in a knapsack sprayer and mixed with water 5 times and shaken evenly, and artificially sprayed into the test places of treatment 1 and treatment 2 evenly, spraying Immediately fill ...

Abstract

The invention discloses a saline-alkali land soil conditioner and a preparation method thereof. The saline-alkali land soil conditioner is prepared by adding water in citric acid, polymaleic acid-acrylic acid copolymer, sodium polycrylate and fatty alcohol-polyoxyethylene ether. The preparation method comprises the following steps: weighing raw materials in weight proportioning; adding partial water in a reaction kettle for heating to 50-60 DEG C; adding the fatty alcohol-polyoxyethylene ether, the polymaleic acid-acrylic acid copolymer, the sodium polycrylate and the citric acid in the reaction kettle in turn for fully dissolving; subsequently, adding rest water in the reaction kettle and cooling to 20 DEG C; and after sampling and qualified inspection, measuring and packaging to form a finished product. By using the conditioner, the physical and chemical properties of the saline-alkali soil are obviously improved, heavy metal ions are complexed, emulsification and oil removal are achieved, salinity infiltration is accelerated, alkaline of soil is neutralized, and the pH value is regulated; and the desalination amount of the conditioner can reach above 50%, and the conditioner has the advantages of short improvement period, durable management effect and universality, saves water, increases benefits, yield and income and is environment-friendly.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a formulation of a conditioner used in saline-alkali soil and a preparation method thereof, in particular to a saline-alkaline soil conditioner and a preparation method thereof. Background technique [0002] my country is a big agricultural country, but not a strong one. The total area of ​​all kinds of saline-alkali land in the country is 1.487 billion mu (1 mu ≈ 667 m 2 ), including 554 million mu of salinized soil, 673 million mu of residual salinized soil, and 260 million mu of potential salinized soil. Soil salinization refers to the phenomenon that the soil contains too much salt, which makes crops less productive or unable to grow. When the salt content of the soil surface exceeds 0.3%, the yield of crops will decrease significantly; when the salt content of the soil surface exceeds 0.6%, most plants cannot grow; when the salt content of the soil surface exceeds 1.0%, Only some plan...
