Embodiment 1

[0028] 1. Modification of corn stalks: at room temperature, crush the corn stalks into powder and pass through 80-200 mesh sieves. Take 10-50 parts by mass of corn stalk powder, 100-200 parts of ethanol, 20-100 parts of 50% NaOH deionized aqueous solution, stir and react at 25-40 degrees for 1-2 hours, then add 15-70 Parts of chloroacetic acid and 45 parts of absolute ethanol, stirred and reacted at 60-80 degrees for 1-2 hours. The reaction solution is neutralized and then filtered, washed and filtered with an ethanol solution with a concentration of 80% to 90%, and dried to obtain the modified corn stalk powder.

[0029] 2. Ultrasonic treatment of corn stalks: Take 2 parts of the modified corn stalk powder in step 1, add 30 to 100 parts of water to fully dissolve it, and use ultrasonic treatment for 4 to 7 minutes to form a modified cellulose solution. At room temperature, 0.1-0.2 parts of cerium ammonium nitrate and 0.225-0.64 parts of HNO3 are dissolved in 5 parts of water...

Embodiment 2

[0033] The preparation method of 1 and 2 is the same as that of Example 1. In the preparation of the nutritional water-absorbing resin, ammonium sulfate: potassium chloride: zinc sulfate: sodium silicate: ammonium ferrous sulfate: boric acid: paclobutrazol=3: 1.27: 0.015: 0.75:0.5:0.025:0.03 solution soaked for 7 to 12 hours, that is, containing 12% of N, containing 12.2% of K, containing 0.06% of Zn, containing 1.3% of Si, containing 1.3% of Fe, containing 0.075% of B, Nutritional water-absorbent resin containing paclobutrazol 0.54%.

[0034]The preparation of the nutritional water-absorbing resin seedling-raising paper of the present invention: the nutritional water-absorbing resin prepared above is evenly sprayed on appropriate paper, then covered with a layer of soft paper, and obtained after drying.

Embodiment 3

[0036] The preparation method of 1 and 2 is the same as that of Example 1, and ammonium sulfate is adjusted in the preparation of nutritional water-absorbing resin: potassium sulfate: zinc sulfate: sodium silicate: ammonium ferrous sulfate: sodium borate: paclobutrazol=3: 1.5: 0.015: 0.75 : 0.5: 0.02: 0.03 After soaking in the solution for 7-12 hours, you can get 11.5% of N, 11.7% of K, 0.058% of Zn, 1.3% of Si, 1.2% of Fe, 0.072% of B, Nutritional water-absorbent resin containing paclobutrazol 0.51%.

[0037] The preparation of the nutritional water-absorbent resin seedling-raising paper of the present invention: the nutritional water-absorbent resin prepared above is uniformly sprayed on appropriate paper, and then covered with a layer of cotton pulp soft paper, and obtained after drying.

Abstract

The invention relates to nutritive absorbent resin seedling raising paper and a preparation method thereof. The preparation method comprises: performing modification and ultrasonic treatment of corn stalks; adding aqueous solution of K2S2O8 into the corn stalks to prepare gel; soaking the gel in mixed nutrition solution to obtain a nutritive absorbent resin; uniformly spraying the nutritive absorbent resin onto paper; and covering the paper with a layer of cotton pulp soft paper and drying the soft paper to obtain the nutritive absorbent resin seedling raising paper. The invention is characterized in that: the seedling raising paper using the nutritive absorbent resin which is made from crop stalks as a main body can reduce soil consumption for raising seedlings, improve seedling raising temperature and reduce workload in a seedling raising process; complex process procedures for raising seedlings by soil and fertilizer are reduced; when the seedling raising paper is used, strong seedlings with thick and strong roots can be obtained; when the seedling raising paper is used in a seedling raising process of rice, tobacco or other plants, nutrients the seedlings need can be supplied continuously with high efficiency; and the use of the paper is convenient, the seedling raising process is simplified, the seedlings are suitable to be planted by machines or hands, the working efficiency of the planting is high and the planting quality is high.

Description

technical field [0001] The invention relates to a nutrient water-absorbing resin seedling paper used for seedling raising of plants such as rice and tobacco. Background technique [0002] Seedling raising of rice and other crops is mainly to improve the quality and quality of plants. In the mid-1990s, with the continuous emergence of high-yield and high-quality rice varieties, rice seedling raising techniques were constantly updated, such as rice dry planting seedlings, floppy seedlings, and nutrient seedling trays, etc., which played a certain role in promoting high rice yields. Chinese patents CN1144594A, CN1145162A, and CN1263698A respectively disclose "a kind of pollution-free nutritional seedling raising tray", "a kind of all-element seedling raising tray", "a kind of degradable slow-release rice and lawn seedling raising composite tray with paper as a carrier", but These seedling trays all have various problems such as weight, large body, easy to leak, easy to scatter...
