Abstract

The invention relates to a granular saline-alkali soil conditioner. The conditioner is prepared from the following raw materials in parts by weight: 70-90 parts of phosphogypsum, 5-15 parts of humic acid and 5-15 parts of filler. The invention also relates to a production method of the saline-alkali soil conditioner. The production method comprises the following steps: preparing the filler, preparing a spray, palletizing, baking, sieving and the like. The granular saline-alkali soil conditioner disclosed by the invention plays a good saline-alkali soil improvement role by combined action of adjusting a plurality of aspects such as the soil pH level and ion components, enhancing the salt resistance ability of crops, activating nutrient elements in soil and the like. The product disclosed by the invention is granular, convenient to use, and convenient for mechanical fertilization. The production method of the product disclosed by the invention has the characteristics that production equipment is low in demands, and just conventional equipment needs to be adopted, special equipment does not need to be added, and the method is wide in raw material source, low in production cost, convenient to transport and fertilize, and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of soil improvement. More specifically, the present invention relates to a granular saline-alkali soil conditioner, and also relates to a production method of the saline-alkali soil conditioner. 【Background technique】 [0002] The large area and wide distribution of saline soil in my country are rare in the world. From the coast of the East China Sea on the Pacific coast to the Tarim and Junggar Basins in Xinjiang, from Hainan Island to the Hulunbeier Plateau in Inner Mongolia, from the shore of Aiding Lake at an altitude of -152m to the Qiangtang Plateau in Tibet at an altitude of 4500m, there are saline soils. According to the statistics of the second national census organized by the Ministry of Agriculture, the area of ​​saline soil in my country is 520 million mu, and 86.5258 million mu has been reclaimed and planted, with great potential for development and utilization. [0003] Saline soil can be r...
