Abstract
The soil improving agent with slowly released fertilizer and in low cost is prepared through dissolving 10 kg of urea in 150 kg of water, adding 240 kg of attapulgite, soaking for 24 hr, stoving at low temperature of 40 deg.c, crushing and pacing. The soil improving agent can inhibit the migration of salts in soil effectively, change aggregate structure of soil obviously, raise the oxygen permeability and water permeability of soil, and make fertilizer release slowly for favoring plant growth. The preparation process is simple and suitable for industrial production.
Description
Technical field
The present invention relates to a kind of provisions agent of improving the soil with low-cost and slow release fertilizer.
Background technology
Current in western desertification treatment and eco-environment restoration and construction, kind of tree and to plant the surviving rate of grass not high, in the western loess organic matter seldom, the content of inorganic salt is but very high, improve soil aggregate, reduce the salt alkali content, increase the necessary for plant growth nutritive ingredient, become key.The present intervention material cost height that uses, performance is single, has restricted widely to use.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of provisions agent of improving the soil with low-cost and slow release fertilizer is provided.
Technical scheme of the present invention is: a kind of provisions agent of improving the soil with low-cost and slow release fertilizer, it is characterized in that: by attapulgite 50-80wt%, polyoxyethylene glycol or polyvinyl alcohol 2-5wt%, fertilizer 18-45wt% forms, above-mentioned fertilizer is selected from mineral manure, organic fertilizer wherein one or both, mineral manure is selected from vitriolate of tartar, potassium hydrogen phosphate, potassium primary phosphate, organic fertilizer is selected from urea, humic acids, the attapulgite particle diameter is 0.03-0.05, polyoxyethylene glycol or polyvinyl alcohol and fertilizer is soluble in water, add attapulgite then, mix the back and under 40-80 ℃ of condition, dry, pulverize.
The present invention has the following advantages: effectively contain the migration of salinity in the soil, obvious variation has taken place in the crumb structure of soil, increases soil oxygen-permeable and water-permeable, and attapulgite has the effect of slow release fertilizer, helps the growth of plant.Preparation technology is simple, is convenient to scale operation.
Embodiment
Embodiment: a kind of provisions agent of improving the soil with low-cost and slow release fertilizer, in 500 liters container, stir and add 10 kilograms polyoxyethylene glycol and 150 kilograms urea down, soluble in water, the attapulgite that adds 240 kilograms then soaks behind the diel 40 ℃ of oven drying at low temperatures, pulverizing, packing.
Claims (1)
1, a kind of provisions agent of improving the soil with low cost and slow release fertilizer, it is characterized in that: 2-5wt% polyoxyethylene glycol and 18-45wt% fertilizer is soluble in water, add the 50-80wt% attapulgite then, the attapulgite particle diameter is 0.03-0.05, mixes back oven dry under 40-80 ℃ of condition, pulverizes.
