Problems solved by technology

However, there are still some problems in cuttings in practical applications: one is how to prevent water loss from the incision and the need for nutrients before rooting, especially for callus rooting plants
It takes a certain amount of time for the cuttings to heal, but in this process, they may rot and die due to the invasion of bacteria. Now the common method is to stick plant ash on the incision, or use antibiotics such as aspirin, but there are also antibacterial effects. Problems with little effect

Abstract

The invention discloses a water-soluble fertilizer applicable for cottage and a preparation method thereof. The water-soluble fertilizer contains urea, urea phosphate, potassium chloride, trace elements, amino acid, a rooting solution and a water-retaining agent; the urea and the urea phosphate take a reaction to produce ammonium polyphosphate; then, the ammonium polyphosphate and other raw materials are homogenized and dried. The rooting solution contained in the water-soluble fertilizer can promote the root system growth; chitosan in the water-retaining agent has good water absorptivity, and can prevent the moisture loss of a cutting slip cut; tea polyphenol can inhibit the germ growth; the amino acid and the trace elements in the water-soluble fertilizer can meet the nutrition absorption of the cutting slips on elements beyond N, P and K; the survival rate can be improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a water-soluble fertilizer suitable for cuttings and a preparation method thereof. Background technique [0002] Cuttings, also known as cuttings, are a common propagation method for cultivating plants. The stems, leaves, roots, buds, etc. of the plant can be cut (called cuttings in gardening), or inserted into the soil, sand, or soaked in water, and can be planted after rooting to make it an independent new plant. In agricultural and forestry production, different plants have different requirements for cutting conditions. [0003] As a common seedling raising method, cuttings are widely used in production and planting, and have the advantages of mass propagation, fast seedling growth, and low cost. However, there are still some problems in cuttings in practical applications: one is how to prevent water loss in the cut and the need for nutrition before rooting, e...
