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 relates to sodium composite fertilizer which can promote the growth of desert plants and increase the drought resistance performance of the desert plants, as well as the application and the fertilizing method thereof. The sodium composite fertilizer is characterized in that the fertilizer consists of the raw materials as follow in weight percent: 0 to 85 percent of sodium nitrate, 0to 22 percent of monobasic sodium phosphate, 0 to 99 percent of sodium silicate, and 0 to 90 percent of sodium chloride. The application of sodium composite fertilizer is that the sodium composite fertilizer can be directly fertilized in plants grown in desert areas or can be used for seeding the desert plants or can be used in the sand cultivation or water cultivation of the desert plants. The sodium composite fertilizer has the fertilizing method that the sodium composite fertilizer is fertilized into the desert soil with 6 kg to 60 kg for one acre, or 0.2 to 3 g of fertilizer is directly fertilized into 1 kg of the soil, or 0.2 to 3 g fertilizer is firstly dissolved with water, and the water-fertilizer mixed solution is fertilized into 1 kg of the soil. The invention has the advantagesof further expanding the vegetation-covered areas of desert areas by providing the sodium composite fertilizer which can promote the growth of the desert plants and increase the drought resistance performance of the desert plants, as well as the application thereof, thereby solving the problem of continuously expanding desertification, and promoting the recovery of the plants and the reestablishment of the ecological system.

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 ...
