Preparation method of soil conditioner

Abstract

The invention relates to a preparation method of a soil conditioner, belonging to the technical field of fertilizer preparation. The soil conditioner is mainly prepared from the following raw materials in parts by weight: 50-70 parts of plant straw carbon, 20-35 parts of fowl / livestock dung, 10-15 parts of bone meal, 1-8 parts of potassium sulfate, 2-8 parts of wood vinegar liquid, 3-9 parts of plant growth regulator and 0.5-1 part of active agent. The preparation method comprises the following steps: preparing carbon powder, pretreating the fowl / livestock dung, preparing a mixture, assaying and detecting, granulating and packaging. The soil conditioner is prepared by mixing the crop straw / bamboo / wood / grass carbon, which is used as the main component, with certain amounts of trace elements, plant growth regulator and bamboo / wood / grass vinegar liquid; since the soil conditioner not only is rich in the three main nutrient elements (nitrogen, phosphorus and potassium) which are essential for crops, but also contains secondary and trace elements, such as calcium, magnesium, sulfur, iron, boron, molybdenum, copper, cobalt and the like, the nutrient proportion of the soil conditioner is reasonable; and when being used as a conditioner, the soil conditioner can increase the organic content of soil and provide more comprehensive nutrients for crops, so that the crops have the advantages of good growth vigor, plump grains and much higher yield.

[0001] The invention belongs to the technical field of fertilizer preparation, in particular to a fertilizer containing plant straw

[0002] A method for the preparation of a charcoal soil conditioner. Background technique

[0003] my country is a large agricultural country. As one of the important agricultural materials, fertilizer is the food of plants and plays a vital role in agricultural production.

[0004] The normal growth of crops requires not only a sufficient amount of various nutrients, but also an appropriate ratio of various nutrients. The appropriate ratio of crops to nutrients is mainly determined by the nutritional characteristics of the crop, the supply capacity of soil nutrients and the applied fertilizer. agrochemical properties. Ignoring any aspect will cause crop nutrient imbalance. According to the results of more than 5,000 field experiments in my country's national fertilizer network, the nutritional status of soil phosphorus and p...
