Abstract

The invention relates to soil conditioner containing sugar refinery alcohol waste liquor, filter mud and peat. The soil conditioner is characterized by being prepared from sugar refinery alcohol waste liquor, the sugar refinery filter mud and the peat at a ratio of (4000-6000):(300-500):(50-150) in parts by weight. The soil conditioner disclosed by the invention has the advantages of balanced influence can be provided for crops; the structural balance of soil is optimized; and the adequacy of the soil nutrient can be kept for a long time.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a soil conditioner comprising sugar factory alcohol waste liquid, filter mud and peat. Background technique [0002] Sugar cane alcohol production waste liquid, or called sugar cane alcohol waste liquid, sugar factory alcohol waste liquid, etc., is an acidic organic wastewater from sugar cane sugar factory or alcohol factory. my country currently discharges about 3 million tons of this waste water every year, which has caused serious environmental pollution problems. This type of waste liquid contains a large amount of N, K, organic matter, chlorine and a small amount of copper. Brazil and my country have already used it directly for sugarcane irrigation in the 1970s and 1980s. Years of test results show that the application of this kind of waste liquid on sugarcane fields not only has a good effect of saving costs and increasing production, but also improves soil structu...
