Problems solved by technology

[0002] At present, the indoor flower and tree hydroponic nutrient provided by the market is generally to drop the nutrient mother liquid into the clear water stored in the pot body, and adjust the pH value of the solution to provide nutrients for the flowers and trees, which is prone to the following problems: First, this type of routine Nutrients are generally only composed of inorganic salts and complex trace elements. Under suitable temperature and light conditions, they can provide mineral nutrition to flower and tree plants with strong root systems. Injured plants and

Abstract

The invention discloses a water culture nutrient agent for flowers and trees and its preparation method, wherein the nourishing agent includes inorganic nutrition, trace element complexing agent and a plurality of organic nourishing compositions, the slow release pelletized granule employs the same nourishing components and adjuvant, which is prepared through the steps of adsorption, embedding, granulating and dressing.

Description

technical field [0001] The present invention relates to flower and tree plant nutrient, especially relates to the nutrient used for flower and tree hydroponics, different dosage forms and preparation method thereof. Background technique [0002] At present, the indoor flower and tree hydroponic nutrient agents provided by the market are generally added dropwise to the clear water stored in the pot body, and the pH value of the solution is adjusted to provide nutrients for the flowers and trees. This is prone to the following problems: First, this type of routine Nutrients are generally only composed of inorganic salts and complex trace elements. Under suitable temperature and light conditions, they can provide mineral nutrition to flower and tree plants with strong root systems. Injured plants and abnormal temperature conditions lower than 10°C or higher than 30°C may cause poisoning or hinder plant growth and development; the second is to directly d...
