Problems solved by technology

Although it is undeniable that they all have certain effects, they all have shortcomings. They cannot make good use of land resources, and only improving the salinity and alkalinity does not have a good effect on the growth of crops.

Embodiment 1

[0016] An improved method for continuous cropping saline-alkali land, comprising the following steps:

[0017] (1) Soil physical adsorption

[0018] Apply soil adsorbent at 300kg / mu, and then use a rotary tiller to plow the soil once. The depth of plowed soil is 40cm, and the soil is finely raked to fully pulverize the soil particles, which is conducive to the release of soil salt. Open a drainage ditch every 8m, and wait for natural sun and rain for 4 weeks; the preparation method of the soil adsorbent is: in parts by mass, 70 parts of peat soil, 30 parts of bamboo charcoal powder, 100 parts of vinegar residue, 100 parts of distiller's grains can be mixed evenly; the drainage ditch is 30cm deep and 25cm wide;

[0019] (2) Plant adsorption

[0020] After soil physical adsorption, according to 200kg / mu, apply decomposed human excrement and urine diluted 5 times, spread green manure after 3 days, shallowly plow the soil by 10cm, and pour biogas slurry dilution once a month; th...

Embodiment 2

[0024] An improved method for continuous cropping saline-alkali land, comprising the following steps:

[0025] (1) Soil physical adsorption

[0026] In the saline-alkali land where irrigation is convenient, apply soil adsorbent at a rate of 500kg / mu, and then use a rotary tiller to plow the soil twice. For the release of salinity, open a drainage ditch every 10m, and wait for the natural sun and rain to drench for 6 weeks; , 200 parts of vinegar dregs, 150 parts of distiller's grains can be mixed evenly; the drainage ditch is 40cm deep and 35cm wide;

[0027] (2) Plant adsorption

[0028] After soil physical adsorption, according to 300kg / mu, apply decomposed human excrement and urine diluted 10 times, spread green manure after 5 days, shallowly plow the soil for 20cm, and pour biogas slurry dilution once a month; the green manure is sweet elephant grass; The preparation method of the biogas slurry dilution is as follows: in parts by mass, mix 30 parts of biogas slurry, 5 ...

Embodiment 3

[0032] An improved method for continuous cropping saline-alkali land, comprising the following steps:

[0033] (1) Soil physical adsorption

[0034] In saline-alkali land with less rainfall, apply soil adsorbent at a rate of 400kg / mu, and then use a rotary tiller to plow the soil once. The depth of plowed soil is 60cm, and the soil is finely raked to fully pulverize the soil particles. To facilitate the release of soil salinity, open a drainage ditch every 9m, and wait for natural sun and rain for 6 weeks; the preparation method of the soil adsorbent is: in parts by mass, mix 80 parts of peat soil, 40 parts of Bamboo charcoal powder, 150 parts of vinegar residues, 130 parts of distiller's grains can be mixed evenly; the drain is 35cm deep and 29cm wide;

[0035] (2) Plant adsorption

[0036] After soil physical adsorption, according to 260kg / mu, apply decomposed human feces and urine diluted 8 times, spread green manure after 4 days of application, shallowly plow the soil 15...

Abstract

The invention relates to an improving method of continuous cropping saline-alkaline land and belongs to the technical field of planting. The method includes: performing soil physical adsorption, plantadsorption and soil granular structure optimization. The method is suitable for most saline-alkaline plant, soil ph can be lowered effectively, soil organic matter content can be increased, and microbial reproduction in soil can be promoted; through the method, mineral ions in the soil can be converted into microbial salt, loss of nutrient in the soil is prevented effectively, restoration of soilfertility is realized, and productivity of the land is improved.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to an improvement method for continuous cropping saline-alkali land. Background technique [0002] Soil salinization is a worldwide problem. The soil in saline-alkali land is compacted, and only some saline-alkali grasses grow, but no crops and crops, which is a great waste of land resources. Salinization of agricultural cultivated land has resulted in reduced production and nearly 500 million mu of abandoned cultivated land. In addition, during the cultivation process, excessive application of chemical fertilizers over a long period of time has resulted in intensified secondary salinization of the soil, serious compaction, and continuous expansion of salinized and alkalized soil. Therefore, the research and implementation of scientific and practical, simple, effective and cheap standardized methods and technical management systems for the improvement of saline-alkali land and dese...
