Embodiment 1

[0027] Embodiment 1: a kind of sodium compound fertilizer and its application and application method, its main features are as follows:

[0028] A 1 .Sodium nitrate and sodium chloride are respectively dissolved in the Hoagland nutrient solution in an amount of 15mmol / L and 35mmol / L with a final concentration, and this mixed solution is the Hoagland nutrient solution applied with sodium compound fertilizer. Hoagland nutrient solution is adjusted 1 / 2 Hoagland nutrient solution (2mmol / L potassium nitrate (KNO 3 ), 0.5mmol / L ammonium dihydrogen phosphate (NH 4 h 2 PO 4 ), 0.25mmol / L magnesium sulfate (MgSO 4 .7H 2 O), 0.1mmol / L calcium nitrate (Ca(NO 3 ) 2 .4H 2 O), 0.5mmol / L iron citrate (Fe-citrate), 92μmol / L boric acid (H 3 BO 3 ), 18μmol / L manganese chloride (MnCl 2 .4H 2 O), 1.6μmol / L zinc sulfate (ZnSO 4 .7H 2 O), 0.6μmol / L copper sulfate (CuSO 4 .5H 2 O), 0.7μmol / L ammonium molybdate ((NH 4 ) 6 Mo 7 o 24 .4H 2O)). Preliminary experiments showed that 2...

Embodiment 2

[0041] Embodiment 2: a kind of sodium compound fertilizer and its application and application method, its main features are as follows:

[0042] A 2 .The sodium nitrate and sodium dihydrogen phosphate dihydrate are uniformly mixed with percentage compositions of 78% and 22% respectively to make sodium compound fertilizer formula 1. Ammonium nitrate and ammonium dihydrogen phosphate with percentage compositions of 66% and 34% are uniformly mixed to prepare nitrogen and phosphate fertilizers. Wherein the amount of nitrogen and phosphorus applied per kilogram of soil in the nitrogen and phosphorus fertilizer treatment is the same as the amount of nitrogen and phosphorus applied per kilogram of soil in the treatment of sodium compound fertilizer formula 1.

[0043] B 2 .Mix the sodium compound fertilizer formula 1 with the soil evenly at a ratio of 0.232g:1kg, then put it in a flower pot, and measure the maximum water holding capacity of the soil. When the soil water content rea...

Embodiment 3

[0049] Embodiment 3: a kind of sodium compound fertilizer and its application and application method, its main features are as follows:

[0050] A 3 .Uniformly mix sodium nitrate, sodium dihydrogen phosphate dihydrate and sodium silicate nonahydrate with a percentage composition of 21%, 6% and 73% respectively to make sodium compound fertilizer formula 2. Ammonium nitrate and ammonium dihydrogen phosphate with percentage compositions of 66% and 34% are uniformly mixed to prepare nitrogen and phosphate fertilizers. Wherein the amount of nitrogen and phosphorus applied per kilogram of soil in the nitrogen and phosphorus fertilizer treatment is the same as the amount of nitrogen and phosphorus applied per kilogram of soil in the treatment of sodium compound fertilizer formula 1.

[0051] B 3 The ratio of the sodium compound fertilizer formula 2 mixed with the soil is 0.882g: 1kg, and other experimental conditions and steps are the same as in Example 2.

[0052] Its effect is s...

Abstract

The invention mainly relates to a sodium compound fertilizer which can promote the growth of desert plants and improve their drought resistance and its application and application method. A sodium compound fertilizer is characterized by comprising the following raw materials by weight percentage: 0%-85% of sodium nitrate, 0%-22% of sodium dihydrogen phosphate, 0%-99% of sodium silicate, and 0% of sodium chloride -90%; the application of sodium compound fertilizer can be directly applied to vegetation in desert areas, or used for seedling raising of desert plants or in sand or hydroponics for desert plants; the application method of sodium compound fertilizer is sodium The amount of compound fertilizer applied to desert soil is 6kg-60kg per mu of land, or 0.2-3g of fertilizer is directly applied to 1kg of soil, or 0.2-3g of fertilizer is first dissolved in 0.05-0.3kg of water, and then The water-fertilizer mixture solution was applied to 1 kg of soil. By providing sodium compound fertilizers and their uses that can promote the growth of desert plants and improve their drought resistance, we can further expand the coverage of vegetation in desert areas, solve the problem of expanding desertification, and promote vegetation restoration and ecosystem reconstruction.

Description

Technical field: [0001] The invention mainly relates to a sodium compound fertilizer capable of promoting the growth of desert plants and improving their drought resistance and application thereof. Background technique: [0002] Due to various reasons of nature, history and reality, our country is currently suffering from desertification. According to the third national desertification monitoring, the desertification area in my country has reached 2.6362 million km 2 , accounting for 27.46% of the total land area. Moreover, with the continuous development of economy and society, the area of ​​land desertification is still expanding, which has seriously affected the living environment of human beings and the economic and social development of the western region. [0003] Scientists from all over the world are trying to solve the major problem of land desertification by promoting the growth of desert plants and improving their drought resistance, but no effective method has ...
