Blueberry soil conditioner and preparation method thereof

Abstract

The invention discloses a blueberry soil conditioner and a preparation method thereof. The blueberry soil conditioner is prepared from the following ingredients in weight ratio: 40-60 parts of water-washed cow dung, 10-20 parts of furfural-residue, 10-25 parts of sawdust, 0.1-0.2 part of a decomposition agent, 3-6 parts of land plaster or 2-4 parts of ferrous sulfate, 15-25 parts of grass carbon and 0.5-1.5 parts of sulphur; the preparation method comprises the following steps: the water-washed cow dung, the furfural-residue, the pine sawdust, and the decomposition agent are mixed uniformly, and then aerobic composting fermentation is conducted; when the temperature of the compost reaches 57-62 DEG C, the land plaster or the ferrous sulfate is added, and fermentation is performed continuously; grass carbon and sulphur are added when the compost is cooled to 48-50 DEG C, uniform stirring is performed, air-drying is performed, and then screening and bagging are performed, so that the blueberry soil conditioner is obtained. The blueberry soil conditioner provided by the invention can regulate the pH value of soil to a range suitable for blueberry growth, prevent the rapid decomposition of organic matters in the soil conditioner, maintain that the organic matter content of soil is higher for a long time, promote the blueberry growth, increase yield of blueberries and improve the quality of the blueberries, meanwhile, resources are used comprehensively, environment is protected, and remarkable ecological and social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of preparation of soil conditioners, in particular to a blueberry soil conditioner and a preparation method thereof. Background technique [0002] Blueberry (blueberry) is a plant of the genus Vaccinium in the Rhododendronaceae. Blueberry fruit is rich in nutrition, contains a variety of health ingredients and has special effects. The International Food and Agriculture Organization lists it as one of the five health foods for human beings. Blueberries are oligotrophic plants, and high-quality blueberries can be cultivated in acidic (soil pH 4.5 to 5.5) and well-permeable loams with high organic matter content (organic matter content higher than 3%). Most of the soil in our country is too high to meet the needs of blueberry growth, which has become the main limiting factor restricting the large-scale development of blueberries. Therefore, before blueberry planting, it is necessary to improve the soil accordi...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly methods for regulating the soil pH value in the cultivation of blueberries: First, the combined application of peat and sulfur powder: but peat is a protective non-renewable resource, and large-scale development will cause great damage to the natural environment

This method cannot be popularized in a large area; the second is the single application of sulfur: although it can effectively reduce the soil pH value, as time goes on, the soil pH value tends to rebound, which cannot solve the problem of low soil organic matter content, and it is easy to cause soil compaction and failure good for blueberry growth

[0004] There are certain shortcomings and deficiencies in the existing technical methods for regulating the soil for cultivating blueberries.
