Problems solved by technology
Although this soilless cultivation method is simple, there are still problems such as defertilization at the later stage of growth and unstable yield in practical applications; and the raw materials used for fermenting organic substrates in various places are complicated, the degree of fermentation varies greatly, and the quality of substrates is unstable. The cultivation effect is not obvious; during the cultivation process, fertilizer needs to be continuously replenished, which is inconvenient to operate and cannot be quantified

Abstract
The invention discloses a fertilizer for a soilless culture technology. The fertilizer mainly comprises 10-20 parts of cake fertilizer, 5-8 parts of mineral potash fertilizer, 3-8 parts of ammonium sulfate, 5-10 parts of magnesium sulfate, 2-6 parts of monopotassium phosphate, 12-15 parts of potassium nitrate, 10-25 parts of chelate iron, 10-15 parts of humic acid, 3-5 parts of calcium sulfate and 1-3 parts of boric acid. The fertilizer is reasonable in formula and good in use effect; the situations of fertilizer shortage, instable yield and the like in the later period of soilless culture are improved, the fertilizer does not need to be continuously supplemented in the culture process, convenience is provided, and a good basis is provided for mass production.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to chemical fertilizers for soilless cultivation. Background technique [0002] At present, soilless cultivation technology has been widely used. There are many forms of soilless cultivation. In my country, substrate cultivation is the main method. The commonly used method is to irrigate with organic or inorganic substrate and nutrient solution prepared by inorganic fertilizer. With the improvement of people's living standards and the aggravation of the pollution of vegetable fertilizers and pesticides, the demand for green vegetables and vegetables has increased rapidly, and vegetables grown in nutrient hydroponics cannot be included in organic or green foods, and nutrient hydroponics requires large investment and technical It is more complicated, and it is difficult for ordinary farmers to grasp. Therefore, organic substrate cultivation has been paid more and more attention i...
