Problems solved by technology

Its water-saving projects include anti-seepage canals, pipe irrigation, drip irrigation, micro-irrigation, and plastic film mulching, etc. These projects require a large amount of investment and are complicated; agricultural water-saving is mainly intensive cultivation. Water measures do not match the amount of labor that needs to be invested, and it is difficult for left-behind labor to accept; biological water conservation is limited by breeding and other industries, and it is difficult to achieve water conservation for each crop by species; chemical water conservation is based on The water-absorbing characteristics of chemically synthesized substances can save water. These chemically synthesized macromolecular materials are likely to pollute the environment, and it is difficult to achieve a win-win situation of water saving and environmental protection. Water-saving fertilizers are mainly slow-release fertilizers that are currently in the development, demonstration and promotion stage. Fertilizers are expensive, and it is difficult to achieve low input and high output when used for general bulk crops, and it is temporarily difficult for farmers to accept

Description

Technical field [0001] The invention relates to a water-saving slag coating bottom fertilization and a production method thereof, and belongs to the field of agricultural chemistry. Background technique [0002] my country is one of the 13 water-poor countries in the world, and agricultural water accounts for about 75% of the total water consumption. Innovating agricultural fertilization methods, developing new types of fertilizers, and saving irrigation water are effective ways to achieve agricultural water saving. However, in traditional agricultural production, in addition to the application of base fertilizer, it is also necessary to apply chemical fertilizer 2 to 3 times during the growth period of the crop. After the topdressing, watering is generally required to increase the total amount of water used. 3 Water production of grain is only about 1kg, which is far lower than the irrigation efficiency of 2.6kg or more in developed countries. [0003] There are many researches ...
