Problems solved by technology

For the improvement and utilization of saline-alkali land, there have been many measures in China, among which the agricultural value of gypsum has attracted more and more attention. Nitrogen, phosphorus, and potassium are almost non-existent, and saline-alkali soil has a lot of toxic substances in addition to high salt content. These are problems that cannot be solved by simply using gypsum.

Abstract

The present invention is one kind of fertilizer specially for improving saline-alkaline land and its production process. The fertilizer is produced with gypsum and organic matter as main material and through one special production process. The production process is one advanced biological organic fertilizer producing process including reasonable matching of gypsum and organic material and fermentation with excellent biological bacterial preparation. The fertilizer has the functions of improving saline-alkaline land, lowering soil alkalinity, lowering soil pH value, promoting formation of granular soil structure, raising soil fertility, raising the yield and quality of crop, reducing crop disease, etc.

Description

1. Technical field [0001] The invention relates to a soil fertilizer, in particular to a special fertilizer suitable for saline-alkali land and land for various economic crops. 2. Background technology [0002] In my country's arable land, saline-alkali land accounts for 6.7%, of which Shandong Province has 1.3 to 1.4 million hectares, and the Yellow River Delta alone has 800,000 hectares. For the improvement and utilization of saline-alkali land, there have been many measures in China, among which the agricultural value of gypsum has attracted more and more attention. Nitrogen, phosphorus, and potassium are almost non-existent, and besides high salt content, saline-alkali soil also contains many toxic substances. These are problems that cannot be solved by simply using gypsum. 3. Contents of the invention [0003] The purpose of the present invention is to provide a method that can improve saline-alkali soil, reduce soil alkalinity, reduce soil pH value, promote the form...
