Special AB fertilizer for leaf vegetable water culture and preparation method thereof

Abstract

The invention discloses a special AB fertilizer for leaf vegetable water culture. The special AB fertilize comprises a fertilizer A and a fertilizer B. The fertilizer A comprises calcium ammonium nitrate, potassium nitrate and ferric sodium diethylenetriamine pentaacetate. The fertilizer B comprises potassium nitrate, magnesium sulfate heptahydrate, monopotassium phosphate, manganese sulfate monohydrate, zinc sulfate heptahydrate, copper sulfate pentahydrate, sodium molybdate, boric acid and auxiliaries. According to the special AB fertilizer for leaf vegetable water culture, a high-efficiencycalcium source is used as a base, a proper amount of fertilizer A containing potassium, chelated trace elements such as iron and the like is added, and hot-process phosphoric acid is used as a base,and a proper amount of phosphate, potassium magnesium and other inorganic and chelated trace elements are added so that precipitation reaction can be effectively prevented; comprehensive and balancednutrition is provided for growth and development of crops, the utilization rate of the fertilizer is increased, hardening is not likely to happen in the storage period, and therefore the fertilizer ismore suitable for the nutrient solution for soilless culture.

Description

technical field [0001] The invention relates to a vegetable planting technology, in particular to an AB fertilizer specially used for hydroponics of leafy vegetables and a preparation method thereof. Background technique [0002] Hydroponics is a new type of plant soilless cultivation method, also known as nutrient liquid culture. Its core is to directly infiltrate the root system of the plant in the nutrient solution. This nutrient solution can replace the soil and provide water, nutrients, oxygen, etc. to the plant. Growth factors that allow plants to grow normally. The nutrients of the nutrient solution are supplied by fertilizers, so suitable fertilizers are the core issue of hydroponic production. The soilless culture nutrient solution must contain 12 elements such as N, P, K, Ca, Mg, S, Fe, Mn, Zn, B, Cu, Mo, etc. at the same time, and the ratio of these 12 elements must be appropriate. However, traditional compound fertilizers and macroelement water-soluble fertiliz...

AI Technical Summary

Problems solved by technology

However, traditional compound fertilizers and macroelement water-soluble fertilizers are not the fertilizers produced for the research and production of soilless cultivation models, and the problem of nutrient deficiency often occurs when used in soilless cultivation.

Moreover, the use of raw material fertilizers can alleviate the problem of nutrient deficiency, but the fertilizer preparation process is complex, requiring multiple and accurate weighing of various raw material fertilizers, and it is prone to errors, and side reactions and precipitation occur, resulting in low utilization of nutrients and failure to produce good nutrients. supply and economics
