Problems solved by technology

[0003] At present, the water-soluble liquid fertilizer on the market has a single component, backward production technology, and poor product quality; insufficient research on production and application technology, promotion of nutrient absorption, increase of active ingredient concentration, increase of system stability, etc.; lack of research on chelating agents, surface activity Development, research and application of agents, new compounds, and functional substances
Moreover, there are many types of products, uneven quality levels, many fake and shoddy products, and the products are still lacking in standards.
At present, the price of water-soluble fertilizers on the market is 5-10 times that of ordinary fertilizers, which is unaffordable for the majority of farmers economically, and it is difficult to popularize and apply them.

Abstract

The invention discloses a pH-stable water-soluble liquid fertilizer which is composed of the following components in percentage by mass: 1-8% of potassium nitrate, 1-10% of potassium dihydrogen phosphate, 0.5-3% of urea, 0.1-3% of potassium sulfate, 0.1-1% of ammonium dihydrogen phosphate, 1-5% of MES and 69-96.3% of water. The invention also discloses a preparation method of the pH-stable water-soluble liquid fertilizer. The invention also discloses application of the pH-stable water-soluble liquid fertilizer in the aspect of plant growth. The pH-stable multielement water-soluble liquid fertilizer can be used in many aspects, and is especially designed for different culture media, including peat, rock wool and expanded clay granules as well as all continuous liquid feed growth systems, such as systems based on aeroponics, drip irrigation, emitters, nutrient solution membrane technique and deepwater culture.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a water-soluble liquid fertilizer with stable pH and its preparation method and application. The fertilizer is suitable for vegetables, fruits and grain crops. Background technique [0002] my country is a large agricultural country short of water, with 1,300 billion m of arable land 2 , the irrigated area of ​​farmland accounts for 56% of the total area of ​​cultivated land. According to my country's water-saving irrigation development plan, it is estimated that by 2030, my country's population will reach 1.6 billion, and the food needs will be about 800 billion kg, an increase of more than 250 billion kg compared with the current one. Therefore, the agricultural irrigation area should reach at least 733.3 billion m 2 above. However, in recent decades, the consumption and waste of water and fertilizer resources in my country's agricultural production has been serious, and the problem of shortag...
