Abstract
The process of improving saline land includes the steps of detecting the salt content in the land, calculating the required amount of ammonium bicarbonate each area unit, dispersing ammonium bicarbonate in the amount of 120 % required amount to the land, rotarily tilling, vibrating and rolling, detecting the alkali content in the land, calculating the required amount of phosphoric acid based on the formula of (alkali content/8.5)x2.1, compounding the phosphoric acid into 1 % concentration water solution and spraying the water solution to the land. The present invention has the advantages of low cost and high saline land improving effect.
Description
Technology neck city
The present invention relates to a kind of method that improves the saline land.
Background technology
China's saline land major part is in uncultivated state at present, and the saline and alkaline arable land of small part output is also very low.About the method for desalting salinized soil, useful fresh water carries out desalination to the saline land, and fresh water is introduced the saline land, to the flushing of saline land burst, then flushing water is entered the drain ditch.Though this method can realize the desalination in saline land, deposit waste fresh water, contain salt in the flushing water, easily environment is produced new destruction.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of method that improves the saline land is provided.
Technical scheme of the present invention is: a kind of method that improves the saline land is characterized in that: the content that comprises the following steps: to detect salt in the soil; Calculate the consumption of every mu of carbonic hydroammonium, carbonic hydroammonium volume value (kg/ mu)=(salt content in the soil-3 ‰) * 50 according to result of calculation, evenly spreads to carbonic hydroammonium on the saline and alkaline ground, uses then the soil rotary tillage; Behind rotary tillage soil 13-15 days, detect the content of alkali in the soil, and calculate the consumption of phosphoric acid or potassium acid, phosphoric acid or potassium acid consumption (kg/ mu) can be determined between (alkali content in the soil/7.5) * 2.1-(alkali content in the soil/7.5) * 2.1; Calculated value according to phosphoric acid or potassium acid consumption, the phosphoric acid or the formic acid of this value are mixed with the aqueous solution that concentration is 1-5%, phosphoric acid or potassium aqueous acid are sprayed in the soil, and the degree of depth in rotary tillage soil is 15 centimetres, with the depressor that shakes on the rotovator soil is shaken behind the rotary tillage soil and presses one time.
The present invention has the following advantages: with low cost, improved effect good, and the improvement instant effect.
Embodiment
Embodiment: a kind of method that improves the saline land, the content of salt in the detection soil; According to the content of salt in the soil, calculate the consumption of every mu of carbonic hydroammonium, carbonic hydroammonium volume value (kg/ mu)=(salt content in the soil-3 ‰) * 50, actual amount is selected 120% of standard value; According to result of calculation, carbonic hydroammonium is evenly spread on the saline and alkaline ground, to use then the soil rotary tillage, the degree of depth in rotary tillage soil is 15 centimetres, with the depressor that shakes on the rotovator soil is shaken behind the rotary tillage soil and presses one time; Behind the rotary tillage soil 15 days, detect the content of alkali in the soil, and calculate the consumption of phosphoric acid, phosphoric acid consumption (kg/ mu) is determined according to (alkali content in the soil/8.5) * 2.1; According to the calculated value of phosphoric acid consumption, it is 1% the aqueous solution that the phosphorylated ligand of this value is made concentration, and phosphate aqueous solution is sprayed in the soil.
