Description

Soil ecological restoration method

Technical Field

The invention belongs to the technical field of soil restoration and utilization, and particularly relates to a soil ecological restoration method.

Background

Pesticides, fertilizers, and the like are the material guarantee for the development of modern agriculture. Pesticides enter the soil through various ways, thereby causing pollution of the soil environment to be serious day by day. Although the soil itself has a purifying effect, for example: volatilization, diffusion, dilution, adsorption, degradation and the like can reduce the pollution degree of pesticides in soil, but if the content of pesticides entering the soil exceeds the self-cleaning capacity of the soil in quantity and speed, namely exceeds the environmental capacity of the soil, the pesticide pollution of the soil can be caused finally. Modern chemical agriculture using materials and techniques such as fertilizers, pesticides, hormones, herbicides, transgenes and the like has reached the end in terms of yield and has reached the cliff in terms of quality. According to reports, agricultural non-point source pollution exceeds industrial pollution, and the food safety problem is serious. Meanwhile, the yield is greatly improved, so that the food produced on the land is not originally nutritious, and the contents of trace elements and the like are mainly reduced.

Pesticide pollution of soil can not only change the normal structure and function of soil and influence the growth and development of plants, but also influence human health through a food chain. Bioremediation technology of soil pesticide pollution has attracted great attention. Bioremediation technology is to utilize the life metabolic process of certain specific organisms including animals, plants and microorganisms to suck away or degrade pollutants in soil relatively quickly so as to achieve the purpose of purifying the soil.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to specific embodiments of the present invention, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a soil ecological restoration method through comprehensive actions of animals, plants, microorganisms, air, sunlight, water and the like, which comprises the following specific operations:

1) selecting a piece of land to be repaired and cured.

2) A cultivated crop is selected, preferably a deep-rooted crop such as a fruit tree.

3) The soil is built according to proper pit and row spacing, namely, the pits are not dug downwards, the soil of the cultivated layer around the pits is stacked into a soil pile with the height of 30 cm along the pits, and the crops are planted in the center of the soil pile so as to ensure that the roots of the crops grow in the cured cultivated layer. The open space with the plough layer removed exposes the raw soil layer to the air and the sunlight for continuous curing, thereby growing weeds and breeding soil microorganisms and continuously becoming fertile.

4) A large amount of weeds growing on soil to be repaired are subjected to first weeding, the weeds are soaked in water to be decomposed and serve as green foam fertilizer (better in closed soaking) to be applied to crops, three hollow pipes with the length of 40cm are uniformly inserted at the positions 20-40 cm away from the crops, and then a small amount of biological bacterial fertilizer (5-10 g each) is applied to the hollow pipes.

5) After the soil heap of the growing crops becomes fertile, a proper amount of earthworms (3-5 earthworms per nest) is put in.

6) The weeds removed each time are soaked in water to prepare a green manure soaking fertilizer or a pulping fertilizer for crop growth and soil microorganism propagation. Applying microbial fertilizer into the empty pipe once every three months until crops grow strongly and soil microorganisms multiply after one year, and then removing the empty pipe. After six months, the cured raw soil around the soil is dug and stacked to the soil pile, the soil pile is continuously widened, and the next layer of raw soil is exposed to be contacted with air and sunlight for curing. The matured raw soil is piled up approximately every six months later, so that the matured soil of the whole land is increased.

The principle analysis of the technical scheme of the invention is as follows:

1) because the weeds have strong vitality and the capability of enriching soil nutrients, the invention utilizes the weeds to provide nutrients for crops and soil microorganisms, so that the crops, the soil microorganisms and the weeds grow out of the sun and can be developed well under the artificial directional intervention.

2) According to the principles of homology of medicine and food and the principle that the vital qi stays in the interior and the evil cannot invade in the yellow emperor's internal classic, nutrient elements (food) required by the growth and development of crops are also the medicines for preventing and treating diseases (plant diseases and insect pests) at the same time; the crops grow and develop healthily, and the vital qi exists in the interior (vigorous metabolism and strong immunity) and is not invaded by exogenous pathogenic factors (plant diseases and insect pests); by adopting the technical measures of the invention, the crops are actively maintained and healthily protected to prevent the occurrence of diseases and insect pests, so that the crops have few diseases and insect pests or even have no diseases and insect pests.

3) As no harmful substances are introduced into the soil in the whole restoration process, the soil is improved only through the comprehensive action of animals, plants, microorganisms, air, sunlight, water and the like, so that the products produced on the soil are ecological, safe and pollution-free. Can effectively change the current situation of agricultural non-point source pollution.

Examples

One mu of mulberries (Taiwan big fruits) are planted in 28 days in 2018, 4 months, and 74 plants are planted according to the total plant-row spacing of 3 meters multiplied by 3 meters. The fruit seedlings are young seedlings which survive in the last year in a cuttage mode. The growth rate reaches 1-2 cm in the first three months, the maximum plant height reaches 1.8 m after three months, the crown diameter is 1 m, and the growth potential is extremely vigorous. Compared with the conventional planting and same variety control, the biomass is increased by more than one third. The mulberry is harvested at the beginning of 4 months in 2019, the yield per mu is 375 kg, the yield per mu of the contrast is only 201 kg, the quality is obviously better than that of the contrast, and the difference is very obvious. Compared with the conventional planting, the method has the advantages that 25 workers (60 yuan/one) are used, the cost is 1500 yuan, the facility cost is 350 yuan for more use, the pesticide and fertilizer consumption is reduced by 560 yuan, and the amount of 1290 yuan is increased compared with the conventional planting. However, the technology produces 174 kg of mulberries (10 yuan/kg), the mulberry yield is 1740 yuan, the economic benefit per mu is increased by 450 yuan (high quality and high price are not calculated), and meanwhile, the excellent ecological benefit is obtained.

The root system of the mulberry planted by the new soil ecological restoration technology grows vigorously compared with the root system of the mulberry planted by the conventional technology, and no mulberry has root rot and poor growth. The overground part growth vigor is obviously superior to that of a control, and the biological yield of the whole plant is obviously increased. Reason analysis: 1. the mulberry planted by the new technology has main roots and lateral roots growing in a plough layer with good soil structure and excellent fertility condition. The phenomenon of poor ventilation of the root system can not occur no matter how watering and rainy days. 2. Because no chemical fertilizer, pesticide or harmful substances are used, the ecological environment of the soil is well protected, the biological diversity is obviously increased, and the number of birds is increased. Meanwhile, soil microorganisms grow vigorously to reach an inherent ecological balance state, and mineral elements, phosphorus, potassium and other elements in the soil matrix are effectively decomposed and released for growth of the mulberry. And the soil azotobacter also grows in a large number, under the effect of the soil azotobacter, the nitrogen nutrition in the soil is obviously increased, the microorganism residues return to the soil to provide nitrogen, and the natural thunder and lightning generates nitrogen dioxide which enters the soil along with rainwater, so that the requirement of the fruit mulberry on the nitrogen is met, and the fruit mulberry has no fertilizer shortage phenomenon in the whole growth period. 3. Because the wild grass has strong nutrition enriching capability, the technology utilizes the wild grass, and the requirements of soil microorganisms and mulberry on nutrition are effectively met by using the green manure soaking and the pulping fertilizer prepared from the wild grass.

The mulberry planted by the new soil ecological restoration technology has excellent quality and excellent taste, and is an excellent model of organic fruits and green fruits. The reason is as follows: 1. the technology does not use pesticide, fertilizer, biological hormone and the like which are relied on by modern agriculture, and the safety and the quality of the product are effectively ensured. 2. Because of the mass propagation of microorganisms, the mineral elements in the parent substances of the soil are effectively decomposed for the fruit mulberry to grow and fruit, so that the mineral elements in the mulberry are more abundant and comprehensive than those in conventional planting, and the nutritive value is greatly improved.

The new soil ecological restoration technology utilizes the wild grass to prepare the pulping fertilizer to irrigate crops, so that the crops and soil microorganisms can obtain biological enzymes (from wild grass living cells) which are not possessed by any other fertilizers, and the metabolic reaction of the crops and the soil microorganisms is greatly increased. Meanwhile, the concentration of carbon dioxide around the crops is increased due to vigorous activities of crop roots and soil microorganisms, so that the photosynthetic efficiency of the crops is correspondingly improved, more organic substances are produced compared with the conventional planting, and the biological yield of the crops is effectively increased.

The new soil ecological restoration technology utilizes the biological diversity and the mutual growth and mutual restriction phenomenon to ensure that the crops have little or no plant diseases and insect pests. Almost prevents harmful substances such as pesticides, chemical fertilizers and the like from entering the environment, and plays a good role in protecting the safety of crop products and the whole ecological environment. The popularization and application of the technology will have subversive influence on the ecological effective utilization of soil.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
