Problems solved by technology
Although today's agricultural water-retaining agents have strong water-absorbing and water-retaining properties, they do not have the nutrients necessary for crop growth
However, although the existing slow and controlled release fertilizers on the market have the advantages of long effective time, high utilization rate, less nutrient loss, and environmental friendliness, they do not have strong water absorption and water retention.
If water-retaining agent and slow-release fertilizer are used separately on crops, it will be inconvenient and the cost will increase, and the compatibility between the two may not achieve the desired effect

Embodiment 1
[0023] Example 1: Preparation of xyloglucan-coated water-retaining slow-release fertilizer
[0024] Put 90 parts of urea granules with a diameter of about 2 mm in the disc granulator, spray atomized water to wet the surface of the urea, then add 10 parts of xyloglucan powder that has passed through a 110 mesh sieve to the disc granulator In the machine, spray 0.5 parts of sodium trimetaphosphate and xyloglucan to mix evenly, to cross-link xyloglucan, and perform rolling coating, so that it can be wrapped on the kernel of the fertilizer as a water-retaining slow-release layer of the fertilizer. Then, it is dried at room temperature to obtain the finished product of coated water-retaining slow-release fertilizer containing urea.

Abstract
The invention discloses a xyloglucan enveloped water-retention slow release fertilizer and relates to the technical field of the slow release fertilizer. The xyloglucan enveloped water-retention slow release fertilizer consists of fertilizer particles and water-retention slow release layers wrapped at the surfaces of the fertilizer particles, wherein the forming material of the water-retention slow release layers is xyloglucan. The macromolecule three-dimensional gel reticular structure formed by pure natural plant polysaccharide is used for building a slow release system, so the xyloglucan enveloped water-retention slow release fertilizer integrating the water retention and the slow release is obtained, and the xyloglucan enveloped water-retention slow release fertilizer has the advantages that the water absorption and water retention performance is very high, the nutrient loss is low, nontoxicity, biological adaptability, biological degradability and environment-friendly effects are realized, and the like.
Description
technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a water-retaining slow-release fertilizer coated with xyloglucan. Background technique [0002] my country is a large agricultural country, and the growth of crops mainly depends on the fertilizer and water used, so increasing the utilization rate of these two can effectively improve the growth of crops. However, during the use of common fertilizers currently on the market, 40-70% of nitrogen, 80-90% of phosphorus, and 50-70% of potassium are lost with soil and water, and have no effective effect on the fertilized crops. This is far below the level of developed countries in the world. In the case of low yields, growers tend to increase the amount of fertilizer used. This may not only have side effects on plants, but also cause huge economic losses and serious environmental pollution. [0003] At the same time, drought and water shortage are one of the importan...
