Abstract

The invention discloses moisture-holding nutritive soil and a preparation method thereof. The method comprises the following steps: weighing citric acid, alpha-naphthaleneacetic acid, corn starch, copper sulfate powder, zinc sulfate powder, borax powder, ferrous sulphate powder and water according to a mass ratio respectively; mixing the raw materials; stirring the mixed raw materials for 30 to 40 minutes at a rotation speed of 100r / min and at a reaction temperature of 80 to 90 DEG C and obtaining micro element chelating liquid for later use; and weighing oil shale dust, furfural slag, calcium carbonate, magnesium sulfate, urea, diammonium hydrogen phosphate, potassium sulphate and acrylic resin water absorbent respectively according to a mass ratio, drying and crushing the raw materials, passing the crushed materials through 100 to 120-mesh sieve, feeding the obtained materials in a stirrer, spraying the micro element chelating liquid in an amount which is 10 to 15 percent based on the mass of the raw materials into the raw materials with stirring, uniformly stirring and obtaining the moisture-holding nutritive soil. The moisture-holding nutritive soil has the advantages that: the nutrients are sufficient; the process is simple; the raw materials are readily available; the micro elements can be absorbed and used by the plants conveniently; water supply capacity and time are improved and prolonged; and the like.

Description

1. Technical field [0001] The invention belongs to nutrient soil for cultivating vegetation, in particular to a water-retaining nutrient soil and a preparation method thereof. 2. Background technology [0002] With the development of society and the improvement of people's living standards, not only the green area is expanding year by year, but also many plants have gradually entered thousands of households. The quality of the ecological environment has become an important indicator for evaluating a city. However, because the soil nutrients for cultivating plants are not sufficient enough, and the water content is also difficult to maintain, the seedlings not only have a low survival rate, but also do not grow luxuriantly. [0003] Oil shale is a kind of sedimentary rock containing organic matter. The proven resource in my country is 2.4 billion tons. As the world's oil, natural gas and other resources are increasingly scarce, the development and utilization of oil shale is...
