Special AB water-soluble fertilizer for soilless culture of fruit vegetables and preparation method of AB water-soluble fertilizer

Abstract

The invention discloses a special AB water-soluble fertilizer for soilless culture of fruit vegetables. The AB water-soluble fertilizer comprises a fertilizer A and a fertilizer B. The fertilizer A comprises the following components in parts by weight: calcium ammonium nitrate, calcium chloride, potassium nitrate and sodium hydrogen ferric DTPA. The fertilizer B is prepared from the following components in parts by weight: potassium nitrate, magnesium sulfate heptahydrate, monopotassium phosphate, ammonium dihydrogen phosphate, potassium sulfate, manganese sulfate monohydrate, zinc sulfate heptahydrate, copper sulfate pentahydrate, sodium molybdate, boric acid and an auxiliary agent. According to the special AB water-soluble fertilizer for soilless culture of the fruit vegetables, a high-efficiency calcium source is used as a basis, 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 basis, 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; and comprehensive and balanced nutrition 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 nutrient solution is more suitable for soilless culture.

Description

technical field [0001] The invention relates to a fruit and vegetable planting technology, in particular to an AB water-soluble fertilizer special for soilless cultivation of fruits and vegetables and a preparation method thereof. Background technique [0002] Fruit vegetables mainly include tomato, eggplant, pepper, etc., which are widely planted all over the country. They have the characteristics of high yield, long harvest period, and rich nutrition, and have become people's main food. However, due to the increasingly fierce contradiction between people's growing demand and increasingly tense land, soilless cultivation has been developed to solve the problem of serious dependence on land. [0003] Soilless cultivation replaces the soil environment with the artificially created root growth environment of crops. It can not only meet the needs of crops for nutrients, water, air and other conditions, but also control and adjust these conditions to promote better growth of cro...

Problems solved by technology

Although the use of raw material fertilizers can alleviate the problem of nutrient deficiency, the fertilizer preparation process is complicated and requires multiple and accurate weighing of various raw material fertilizers, so it is easy to make mistakes, and prone to side reactions and precipitation, resulting in low utilization of nutrients and failure to produce Good nutrient supply and economic benefits
