Abstract

The invention provides a soil conditioner and an application method thereof. The soil conditioner is prepared from the following raw materials in parts by weight: 0 to 50 parts of calcium fertilizer,0 to 30 parts of magnesium fertilizer, 0 to 40 parts of potassium fertilizer, 5 to 50 parts of silicon fertilizer, 5 to 10 parts of humic acid and 5 to 10 parts of attapulgite. Compared with the priorart, production raw materials of the soil conditioner disclosed by the invention are prepared from natural minerals, have lost cost and are convenient to take. The produced soil conditioner are prepared from the calcium fertilizer, the magnesium fertilizer, the potassium fertilizer, the silicon fertilizer and the like and can effectively activate and supplement nutrients of calcium, phosphorus, potassium and the like which are fixed by acidification for soil; in use, the produced soil conditioner can achieve a balanced fertilizing effect. The soil conditioner has the advantages of simple production mode, easiness, practicability and wide popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of farmland restoration, and in particular relates to a soil conditioner and an application method thereof. Background technique [0002] Most of cadmium in nature exists in the form of sulfur cadmium ore, but with the continuous development of society, cadmium has been widely used in nuclear industry, battery industry, electroplating industry, plastic industry, etc. Some scientists at home and abroad have found that excessive cadmium content in soil will lead to a decline in the yield and quality of agricultural products and limit the sustainable development of planting. For animals and most humans, dietary intake is the primary route of cadmium exposure. The World Health Organization stipulates that the maximum allowable intake of cadmium for the human body is 1ug / (Kg·d), and all countries have also stipulated the cadmium content limit indicators in food crops. [0003] In the study of environmental cadm...
