Soil conditioner containing rare earth and sepiolite and preparation method thereof

Abstract

The invention relates to a soil conditioner containing rare earth and sepiolite. The soil conditioner is prepared from the following ingredients in parts by weight: 1 to 3 parts of agricultural rare earth, 11 to 15 parts of sepiolite, 2 to 5 parts of ammonium chloride, 1 to 3 parts of calcium superphosphate and 3 to 6 parts of potassium sulphate. A preparation method of the soil conditioner comprises the following steps of A, preparing materials; B, crushing the materials into powder being 61 to 80 meshes; C, uniformly stirring the powder to obtain a soil conditioner mixture; after qualified detection, performing split charging on the mixture into packages with various specification weights in each bag; obtaining the soil conditioner finished product containing rare earth, sepiolite and nitrogen, phosphorus and potassium elements. In the use process, the soil conditioner is blended into a common fertilizer according to a weight ratio being 1 to 100; the mixture is used as a base fertilizer or an additional fertilizer of crops; field fertilizer application experiment results show that the yield is generally increased by 10 to 30 percent; the yield increase of rice is 20 percent; the yield increase of cotton is 25 percent; the yield increase of vegetables is 30 percent.

Description

technical field [0001] The invention relates to the technical field of soil fertilizer, in particular to a soil conditioner containing rare earth and sepiolite and a preparation method thereof. Background technique [0002] At present, chemical fertilizers are commonly used in rural fields in my country, which seriously damages the basic structure of the soil, causes soil compaction, reduces fertility, and causes serious pollution to the soil, especially some harmful heavy metals such as lead, cadmium, chromium, Arsenic and mercury are more harmful to crops. Not only will the yield of crops decrease, but they will also be unsalable due to the harmful heavy metals contained in agricultural products. If these contaminated grain and oil crops are eaten, people's health will be seriously damaged. [0003] Rare earth is a group of elements in the periodic table of chemical elements. It is composed of 15 elements such as cerium, praseodymium, and neodymium, which are very similar i...

Problems solved by technology

[0004] How to use sepiolite combined with the similarities and different functional characteristics of rare earths to apply to agriculture will exert greater potential to reduce the amount of fertilizer applied to crops, improve soil, increase crop yields, and reduce chemical fertilizers. The pollution of the environment is the direction that the vast number of agricultural science and technology workers are striving for in recent years. So far, no reports have been found about the application of rare earth and sepiolite compositions in agriculture.
