Problems solved by technology

See CN 1298850A "Fertilizer for drip irrigation and its production method" (application number 99123097.3), CN1453251A "acidic liquid fertilizer for drip irrigation and its preparation method" (application number 02117185.8), CN 1257854A "a fertilizer for saline-alkali land and its production method" (Application No. 99117442.9) and CN 1544397A "Plant Stress Resistant Fertilizer" (Application No. 200310113496.5), the first two fertilizers are suitable for drip irrigation, but do not have the effect of salt resistance, and only contain a large amount of elements nitrogen, phosphorus, Potassium, the nutrients supplied to crops are not comprehensive enough
The third type of fertilizer is suitable for saline-alkali soil, using rare earth compounds to improve the adaptability of crops to saline-alkali soil, and cannot be used with sprinkler and drip irrigation equipment

Abstract

The invention relates to a salt-resistant multielement drip irrigation fertilizer, which is prepared from monopotassium phosphate, urea, potassium chloride, sodium selenate, sodium silicate, magnesium sulphate, zinc chloride, ferrous chloride, manganese chloride, boric acid, calcium chloride, composite chelating agent, acidity conditioning agent and ammonium chloride, wherein the crystal nucleon substance is the mixture of ammonium chloride and potassium chloride by the ratio of 2:1.

Description

technical field [0001] The invention relates to a salt-resistant multi-element drip irrigation fertilizer and a preparation method thereof, belonging to the technical field of agricultural fertilizers. Background technique [0002] Soil salinization is a worldwide resource problem and ecological problem. According to statistics, there are about 950 million hectares of various saline soils in the world, accounting for 10% of the global land area, and are widely distributed in more than 100 countries and regions. Moreover, due to the secondary salinization of soil, the area of ​​global salinization is still increasing rapidly. The development of soil salinization has brought serious economic losses and ecological hazards. Statistics from the World Food and Agriculture Organization and UNESCO show that about half of the world's irrigated land suffers from salinization to varying degrees, and about 10 million hectares of land are abandoned each year due to secondary salinizati...
