Embodiment 1

[0025] Embodiment 1. Intelligent nutritional sand 1

[0026] Bond 2.31 parts of binder to the surface of 76.92 parts of 40-mesh raw sand grains, then bond 11.54 parts of nitrogen, phosphorus and potassium fertilizers with a weight ratio of 1:1:1 to the surface of the binder, and then wrap 5.38 parts of resin to the surface of the fertilizer and attach 3.85 parts of water-retaining agent to the surface of the resin, the binder used is cyanoacrylate adhesive, the raw sand used is desert aeolian sand, the resin used is phenolic resin, and the water-retaining agent used is modified Carboxymethylcellulose.

[0027] The above-mentioned mixture is stirred with a stirrer until it is uniformly mixed until it becomes single-grained to obtain the intelligent nutritional sand 1 of the present invention.

Embodiment 2

[0028] Example 2. Intelligent nutritional sand 2

[0029] Bond 2 parts of binder to the surface of 70 parts of 60-mesh raw sand, then bond 10 parts of NPK fertilizer with a weight ratio of 2:1:1 to the surface of the binder, and then wrap 5 parts of resin To the surface of the fertilizer and attach 3 parts of water-retaining agent to the surface of the resin, the adhesive used is silica gel adhesive, the raw sand used is desert aeolian sand, the resin used is polyester resin, and the water-retaining agent used is sodium polyacrylate.

[0030] The above-mentioned mixture is stirred with a stirrer until it is fully mixed until it becomes single-grained to obtain the intelligent nutritional sand 2 of the present invention.

Embodiment 3

[0031] Embodiment 3. Intelligent nutritional sand 3

[0032] Bond 3 parts of binder to the surface of 80 parts of 70-mesh raw sand grains, then bond 13 parts of NPK fertilizer with a weight ratio of 2:2:1 to the surface of the binder, and then wrap 6 parts of resin to the surface of the fertilizer and attach 4 parts of water-retaining agent to the surface of the resin, the binder used is vinyl acetate polymer latex adhesive, the raw sand used is desert aeolian sand, the resin used is polyamide resin, and the water-retaining agent used is polyvinyl acid.

[0033] The above-mentioned mixture is stirred with a stirrer until it is uniformly mixed until it becomes single-grained to obtain the intelligent nutritional sand 3 of the present invention.

Abstract

The invention discloses intelligent nutritional sand and a preparation method thereof, belonging to the field of sand planting. The intelligent nutritional sand disclosed by the invention comprises the following raw materials in percentage by weight: 2-3% of binder, 5-6% of resin, 10-13% of fertilizer, 3-4% of water retaining agent and 70-80% of raw sand. The preparation method of the intelligent nutritional sand, disclosed by the invention, comprises the steps of binding the binder in proportion to the surface of raw sand grains; then, binding the fertilizer to the surface of the binder, and wrapping the surface of the fertilizer with the resin; finally, adhering the water retaining agent to the surface of the resin. The intelligent nutritional sand and preparation method thereof disclosed by the invention have the advantages of cleanness and sanitation, safety in use, strong moisture and fertility preserving ability, sustained release of fertilizer, and the like.

Description

technical field [0001] The invention relates to the field of sand planting, in particular to an intelligent nutritional sand and a preparation method thereof. Background technique [0002] Traditional planting in the family is very vulnerable to pests and diseases. Once pests and diseases appear, the medicines used for treatment will pollute the planting substrate and indoor environment. One of the main sources of plant diseases and insect pests in home planting is the cultivation medium. With the repeated use of the potting medium, the nutrients and water continue to decrease, and the number of germs and insect eggs increases. Existing family planting substrates include traditional soil substrates and soilless substrates, etc., but the above-mentioned problems will occur in these two substrates during use. [0003] In view of this, it is indeed necessary to provide a new planting substrate that is clean, safe, and has a strong ability to retain water and fertilizer and a p...
