Abstract

The invention discloses a grape soilless culture nutrition solution, a preparation method and a use method thereof, wherein the grape soilless culture nutrition solution comprises a large amount of anelement nutrition solution and trace elements, the element nutrition solution comprises a pre-emergence nutrition solution, an early-stage flowering period nutrition solution, a late-stage floweringperiod nutrition solution, a veraison period nutrition solution and a harvesting period nutrition solution, and the trace elements comprise a trace element A and a trace element B. According to the present invention, the corresponding liquid fertilizer formula is formed according to the dynamic law of the requirements on mineral elements at each growth stage, such that the grape soilless culture nutrition solution can provide effect on the grow of plants, flowers and fruits; and the grape soilless culture nutrition solution can conveniently integrate the water-fertilizer integrated system so as to achieve the precise supply of mineral elements and water and save nutrition.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a nutrient solution for soilless cultivation of grapes, a preparation method and a use method thereof. Background technique [0002] Due to the variety of soils, the types and amounts of fertilizers required by grapes are also different under different soil conditions, resulting in no uniform standard for grape fertilization. The existing amount of fertilizer application and fertilizer selection are mainly determined by local cultivation experience. The demand for mineral elements and water changes at different stages of grape growth, making it difficult to precisely control fertilizer and water. [0003] At present, grapes are mainly cultivated in soil. Under soil cultivation conditions, precise control of fertilizer and water management cannot be achieved, but under soilless cultivation conditions, precise management of fertilizer and water can be achieved. The...
