Problems solved by technology

Although the sustained-release duration is extended to a certain extent, the release rate is still high in the early stage, resulting in shortened oxygenation time; and in the later period, with the decrease of oxygenate content, its release power is seriously insufficient, resulting in subsequent oxygenation. no significant effect
At the same time, the fertilizer only has the effect of increasing oxygen and does not contain other nutrients, so it cannot have a slow-release effect on other nutrients

Abstract

The invention relates to the field of agricultural planting, and discloses oxygen-increasing fertilizer for nursery stocks and a preparation method thereof. The fertilizer comprises a quick-release layer, a slow-release layer and an envelope layer, wherein the quick-release layer is composed of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, trace element fertilizer, a chemical oxygen-increasing agent, a plural gel carrier, modified calcium oxide and an adhesive; the slow-release layer is composed of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, trace element fertilizer, a chemical oxygen-increasing agent, cyclodextrin and an adhesive; and the envelope layer is made of alcohol-soluble high molecular resin. The oxygen-increasing fertilizer for nursery stocks is suitable for nursery stock growing, has a slow-release effect, can continuously and stably release nutrients and oxygen, and promotes growth of the nursery stocks. The preparation method of the oxygen-increasing fertilizer for nursery stocks is simple and reasonable, the prepared oxygen-increasing fertilizer for nursery stocks is stable in quality, and the preparation method is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a seedling oxygen-increasing fertilizer and a preparation method thereof. Background technique [0002] Seedlings are saplings with a root system and a stem. Seedlings are generally in the stage of rapid growth, especially the growth of the roots is particularly fast. Rapid growth requires the roots to absorb a large amount of nutrients, and absorbing nutrients requires the roots to perform a large amount of respiration to provide energy. Therefore, in order to enhance the respiration of the roots of seedlings, it is necessary to loosen the soil frequently, keep the soil fluffy, and increase the oxygen content. However, artificial soil loosening is time-consuming and laborious, and it is not convenient enough. For this reason, people have added oxygen enhancers that can release oxygen in fertilizers. For example, the Chinese invention patent with the application number CN...
