Description

technical field [0001] The invention relates to the technical field of preparation of agricultural fertilizers, in particular to a special liquid rooting fertilizer for vegetables with multiple nutrients (hereinafter referred to as: rooting fertilizer) and its preparation method and application. Background technique [0002] The root system is the main site for vegetables to absorb nutrients and water. The quality of vegetable root growth directly determines its yield and quality. Therefore, it is very important to promote the development of vegetable roots. Traditionally, people mainly increase the yield of vegetables by applying organic fertilizers, spreading or topdressing chemical fertilizers; instead of applying fertilizers based on the growth and development of vegetable roots and the laws of nutrient absorption, the formula composition of conventional fertilizers is not very reasonable; At the same time, the blind application of a large number of chemical fertilizers...
