Problems solved by technology
Salinized soil contains more salt, which is not suitable for plant growth, resulting in large areas of land being left unused and barren
[0003] In order to solve the problems of soil compaction and salinity, people now mostly use organic fertilizers, soil improvers or plant saline-alkali-tolerant plants, but these methods have certain limitations. The improvement speed of ordinary bio-organic fertilizers is slow and will not be achieved in the short term. There are more obvious effects; the area of saline-alkali land in my country is relatively large, but there are few saline-alkali-tolerant plant varieties suitable for planting, and the problem of soil salinization cannot be fundamentally improved; soil improvers contain various soil adsorbents, acidification agent, chemical modifier, humic acid and rooting factor, the preparation cost is relatively high, and it is not suitable for large-scale application

Embodiment 1
[0014] Example 1: Animal manure, straw, crop bran, etc. are mixed and piled into a long ridge with a trapezoidal cross section, and then fermented to obtain decomposed matter; put into the decomposed matter according to the dosage of 0.5-0.8kg / ㎡ For worm species, breed earthworms in an environment with a temperature of 20-30°C and a humidity of 60%-80% to obtain vermicompost, separate the earthworms from the vermicompost, collect the vermicompost to dry and pulverize; the pulverized vermicompost is evenly Sprinkle it on the leveled land surface and turn it into the soil, and the amount of vermicompost is 800kg / mu.
Embodiment 2
[0015] Embodiment 2: breed earthworms according to the method of embodiment 1, after collecting earthworm castings, earthworm castings are mixed evenly with other organic fertilizers according to the weight ratio of 1:2, spread on the flat land surface, and turn into the soil, wherein mixing The amount of fertilizer is 1000kg / mu.

Abstract
The invention provides a soil improvement method which is characterized by the following steps: strip ridges which are formed by stacking and retting of animal waste, straws, crop bran and the like are fermented, wherein the cross sections of the strip ridges are trapezoid, and fermented substrate is obtained; earthworms are bred so that earthworm waste is obtained, and the earthworm waste is separated, collected, dried and smashed; and the earthworm waste is spread, wherein the dosage of the spread earthworm waste is not less than 600 kg / mu. Due to the fact that the earthworm waste contains a lot of major elements, such as nitrogen, phosphorus and potassium, needed by plants, and is rich in 18 types of amino acid which is not contained in normal animal waste, 5 types of biological active enzyme and a lot of microelements such as copper, zinc, manganese, iron, selenium, calcium and magnesium, by means of the ion exchange theory and salt transformation theory, and by the mutual combination of a quick effect and a slow effect, soil hardening and physicochemical shape of salt and alkali can be improved, potential of hydrogen (pH) value and salt content can be reduced, fertility of soil can be improved, and alkali changing and fertility fostering are integrated. Due to the fact that the raw materials are wide in source, production cost is easy to control, the soil improvement effect is good, crops can grow very well and income of farmers can be improved.
Description
technical field [0001] The invention belongs to the technical field of soil improvement, in particular to a soil improvement method. Background technique [0002] At present, the general dry land of cultivated land soil in our country has different degrees of compaction. There are three main reasons for soil compaction: one is the rolling action of heavy machinery in the field, and the other is the precipitation of rainfall and flood irrigation that produce surface runoff; The third is the application of excessive ammoniacal nitrogen fertilizers, potassium fertilizers and other chemical fertilizers. The above-mentioned massive structure and aggregate structure that are easy to damage the soil make the soil particles suspended in the water difficult to settle, thus causing soil compaction and affecting the growth of crops. Secondly, my country has a large area of saline-alkali land, especially in some arid and semi-arid areas, where precipitation is low and evaporation is ...
