Problems solved by technology

The mixture of matrine and fulvic acid in the liquid fertilizer of this invention increases the hormone-like content and promotes the absorption of nutrient elements in the roots. Gibberellin stimulates the hormone-like fermentation in seaweed essence, promotes root development, and accelerates crop growth. The price of alkali, gibberellin and seaweed essence is high, and the cost increases, which is not conducive to wide application

Abstract

The invention relates to a rooting promoting liquid fertilizer, and a preparation method and application thereof. The rooting promoting liquid fertilizer comprises the following raw materials: a macroelement fertilizer, a microelement fertilizer, a compound amino acid, potassium dihydrogen phosphate, a plant growth regulator, chitosan and a water retaining agent, wherein the weight ratio of the plant growth regulator to the potassium dihydrogen phosphate is 1:(1000-2500). The invention also provides the preparation method and application of the rooting promoting liquid fertilizer. The liquid fertilizer disclosed by the invention is comprehensive in nutritional ingredients and is suitable for nutrition requirements of various crops in growth periods, the growth of root systems can be obviously promoted, soil can be improved, the disease resistance and the stress resistance of the crops are enhanced, and the target of reducing the fertilization amount is achieved.

Description

technical field [0001] The invention relates to a root-promoting liquid fertilizer and a preparation method and application thereof, belonging to the technical field of liquid fertilizers. Background technique [0002] Liquid fertilizer is a kind of fluid water-soluble fertilizer. Because of its advantages of uniform nutrient, flexible formula, simple production, convenient use and high fertilizer utilization rate, it is more and more accepted by people, especially with the improvement of modern irrigation facilities and The advantages of liquid fertilizers are becoming more and more obvious. [0003] At present, most of the liquid fertilizers in my country are nutritional fertilizers based on liquid nitrogen fertilizers and liquid compound fertilizers. They focus on the supplementation and absorption of a large number of elements needed by crops, such as nitrogen, phosphorus, and potassium, but ignore the effect on crop roots. The root system is an important organ for crops...
