Abstract

The invention relates to the improvement and fertility betterment of farmland soil, particularly disclosing a fertility-betterment type soil-conditioner and the preparation method thereof. The soil conditioner is made by the following raw material of different weights: 50 to 55 portions of alkaline residue, 32 to 35 portions of peat, 12 to 14 portions of light-burned dolomite and 3 to 4 portions of ammonium bicarbonate. The preparation method is that the alkaline residue, the peat and the ammonium bicarbonate are mixed by the above weight proportion and stirred and accumulated for 5 to 7 days. Then the light-burned dolomite with the above weight proportion is added. At last, the soil conditioner is grinded and bagged. The soil conditioner of the invention has the advantages of good exterior, stable physicochemical characters, no moisture absorption and non-lumping, which can be widely used for improvement and fertility betterment of the southern acid soil and supplies balanced calcium, magnesium, and other nutrients for the crops.

Description

technical field [0001] The invention belongs to the agricultural technology and relates to the improvement and fertilization of cultivated land soil, in particular to a fertilization type soil conditioner and a preparation method thereof. Background technique [0002] The alkali slag produced by the ammonia-soda process to manufacture soda ash is a kind of industrial waste. The main component is CaCO 3 and Ca(OH) 2 , and contains a certain amount of Mg(OH) 2 And a small amount of other medium and trace elements, alkaline, processed products can improve acidic soil and provide calcium and magnesium nutrients for crops. Because the alkali slag is rich in calcium and less in magnesium, and CaCO 3 In the process of agricultural use, the processed products have insufficient stability in soil improvement, poor calcium and magnesium activity and their balanced supply. In addition, the physical properties of alkali slag are very poor, especially the dry alkali slag is hard, whi...
