Description
Method for Restoring Acidified and Degraded Soil of Economic Forest
The invention relates to the technical field of acidified and degraded soil restoration, in particular to an economic forest acidified and degraded soil restoration method.
The economic forest, also known as "special-purpose forest", is a forest with the main purpose of producing fruit, edible oil, industrial raw materials and medicinal materials. According to the different utilization positions of the wood, the forest can be roughly divided into:(l) woody oil forest using seeds as oil pressing raw materials, such as Camellia oleifera, olive tree and walnut tree;(2) tea forest and mulberry forest using leaves as raw materials;(3) fiber forest and cork forest using bark as raw materials, such as paper mulberry and cork oak;(4) forest using branches as weaving raw materials, such as twigs of the chaste tree and willows;(5) rubber forest and lacquer tree using tree liquid. The high-value conomic forest is usually under intensive management, and is an important measure to develop mountain area and make rational use of natural resources.
The rapid development of economic forest industry not only effectively improves the ecological environment, but also plays a very important role in effectively increasing farmers' income, revitalizing economy, flourishing urban and rural markets, optimizing food structure and promoting social stability.
Soil is the dominant factor among the ecological factors affecting the distribution of economic forests, which has important influence on the growth and distribution of economic forests. In recent years, the growing soil acidification in economic forest has greatly influenced the good growth of economic forests. Soil acidification is an expression form of soil degradation, which refers to a natural phenomenon that soil acidity increases and becomes strongly acidic or strongly acidic. At present, the soil acidification trend of the economic forest has become more and more severe, and it's common to notice the acidification of a large amount of land. However, the soil acidification can cause the reduction of the nutrient utilization rate and the increase of harmful bacteria in the soil, and directly influence the yield and the quality of the economic forest.
The traditional method for acid soil improvement is to spread lime or limestone powder alone, and the application of the lime can obviously reduce the acidity of the acid soil, but sometimes reacidification may be enhanced. In the market, there are also some acid soil composite conditioners, with the main component being the mixture of lime and some minerals or industrial by-products, but most of these conditioners contain a certain amount of toxic metal elements, such as lead, cadmium, arsenic and chromium, which may pollute the soil environment. Till now, the acid conditioners have only one single function, and the traditional manure collection mode is adopted aiming at enhancing the soil fertility; during the manure collectionprocess, organic substances and nitrogen elements in the manure content are gradually and severely lost. If such loss can not be improved, the fertility will be severely damaged and result in lower yield and quality of the economic forests.
On the basis of the problems existing in the restoration of the acidified and degraded soil of the economic forests, it's urgently needed to provide a method capable of improving the organic matter content of the soil and the quality and the yield of the economic forests.
The invention aims to provide an economic forest acidified and degraded soil restoration method so as to solve the problems existing in the prior art.
The invention provides a method for restoring acidified and degraded soil of economic forest, which comprises the following steps:
Si: Deeply plough the acidified and degraded soil of the economic forest to be restored to 50-80 cm away from the surface to form plough layers;
S2: About 20-23 days later, plough the economic forest acidified and degraded soil to 45-55 cm away from the surface again, reclaim the economic forest acidified and degraded soil by 50 cm, dig and expose the deep soil;
S3: Apply and sow the economic forest acidified and degraded soil conditioner and the improved compound fertilizer, and mix them with the ploughed soil;
The usage amount of the economic forest acidified and degraded soil conditioner is 255-285 kg/mu, and the usage amount of the modified compound fertilizer is 3,100 4,800 kg/mu.
Further, the economic forest acidified and degraded soil conditioner includes calcium carbonate and calcium hydroxide.
Further, the improved compound fertilizer is formed by mixing biogas fertilizer, chemical fertilizer and polypotassium selenium phosphate compound fertilizer.
Further, the method for preparingg the economic forest acidified and degraded soil conditioner comprises the following steps:
Respectively grind calcium carbonate and calcium hydroxide, wherein the fineness of the calcium carbonate and the calcium hydroxide is required to be 95% when passing through 45-mesh sieve to obtain ground calcium carbonate and calcium hydroxide powder;
Fully mix the ground calcium carbonate and calcium hydroxide powder according to the weight ratio of 5:1 to prepare the economic forest acidified and degraded soil conditioner.
Further, the method for prepaidg the biogas fertilizer comprises the following steps: put waste straws and animal excrement into a biogas pool as original materials, and prepare the biogas fertilizer by using anaerobic fermentation residues.
After the domestic organic wastes are fermented by methane, carbon elements contained in the domestic organic wastes can be converted into methane to be utilized as energy sources, nitrogen elements can be fermented into ammonium nitrogen and protein nitrogen to be stored as nitrogen fertilizers, and on the other hand, trace elements such as phosphorus and potassium will also be enriched in the fermentation, and the trace elements are essential elements for crop growth, so that the domestic organic wastes are very beneficial to plant absorption. Meanwhile, humic acid and ammonium nitrogen in the biogas fertilizer are fast-effective fertilizers, and can be rapidly decomposed after entering the soil so as to increase the fertilizer efficiency.
Methane fermentation residue is an ideal organic fertilizer, and long-term application of this fertilizer in economic forests plays a very important role in establishing high yield and stable-yield economic trees, improving soil and cultivating soil fertility.
Further, the process of preparing the improved compound fertilizer comprises the following steps: dissolve the polypotassium selenite compound fertilizer into a biogas fermentation broth at the dosage ratio of 0.56 mg/kg of the polypotassium selenite compound fertilizer to the biogas fertilizer; then stack the dissolved biogas fermentation broth and organic garbage or soil into a plurality of layers, wherein the height of each layer is 40 cm; cover and add a layer of organic wastes or soil with the same thickness to form a round fertilizer pile; 25 days later, form the biogas humic fertilizer; and add the chemical fertilizer into the fertilizer pile at the dosage ratio of 1:120 of the chemical fertilizer to the biogas fertilizer to the biogas fertilizer to generate the improved compound fertilizer.
Further, the chemical fertilizer is ammonium fertilizer, calcium phosphate fertilizer or ammonium sulfate and calcium superphosphate compound fertilizer.
Further, the method for preparingg the polypotassium selenium phosphate compound fertilizer comprises the following steps:
Add selenium powder with purity of 99.999% into a reactor to react with 28% nitric acid, then concentrate, filter, dry and thermally decompose the product to obtain selenium dioxide;
Then dissolve it in water to obtain selenous acid, weigh potassium carbonate powder and 87% phosphoric acid at the molar ratio of 1.4:1, dissolve potassium carbonate in purified water at the ratio of 1:1.5, slowly add phosphoric acid while stirring to carry out neutralization reaction, then dehydrate, dry, and generate potassium polyphosphate at 400°C;
Weigh selenium dioxide and potassium polyphosphate at the molar ratio of 1.5:1, hydrolyze the selenium dioxide into selenous acid to obtain selenous acid with the concentration of 0.25 g/ml, then slowly add the potassium polyphosphate into the selenous acid for chemical reaction, keep stirring in the reaction process, and finally dehydrate, deacidify and compound them at 260-280°C to obtain the potassium selenite polyphosphate compound fertilizer.
The invention discloses the following technical effects:
1. The reacidification can be reduced by adopting calcium carbonate and calcium hydroxide. In addition to treating both symptoms and root causes, it does not contain industrial byproducts in raw materials, therefore, no toxic metal elements will be introduced to pollute soil;
2. By adopting the biogas fertilizer in the improved compound fertilizer mentioned in the invention, the biogas fertilizer can advance the absorption of nitrogen and phosphorus nutrients by the economic forest soil, improve the utilization rate of nitrogen and phosphorus, increase the organic matter content of the soil, and accumulate the contents of total nitrogen, alkali-hydrolyzable nitrogen, fast-effective phosphorus and fast-effective potassium, as a result, the yield of the economic forest doubles several times; the combined application with chemical fertilizer can achieve better performance;
3. The selenium content of the economic forest can be comprehensively and thoroughly improved by improving the potassium selenite polyphosphate compound fertilizer in the compound fertilizer, so that the potassium selenite polyphosphate compound fertilizer can be well absorbed by the economic forest, and the application mode is very simple and convenient.
