Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a combined fertilizer for cucumbers and an application method thereof. Background technique [0002] Scientific fertilization is one of the important measures to obtain high yield of cucumber. Cucumbers need a variety of nutrients during the growth process. Since the nutrients in the soil are limited, these nutrients need to be supplemented in a timely and reasonable manner according to the soil conditions and the needs of cucumbers in order to obtain high and stable yields. However, cucumbers have their own rules for absorbing nutrients. Different growth stages absorb different amounts of various elements, and the same growth stage absorbs different nutrients. At the same time, there are problems such as loss and failure caused by fertilizer application into the soil, such as loss and fixation. Therefore, according to the nutrient absorption characteristics of cucumber, co...
