Embodiment 1

[0026] 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 1 part of chloroacetic acid and 45 parts of absolute ethanol, stirred and reacted at 60 to 80 degrees for 1 to 2 hours, neutralized the reaction solution and filtered, washed and filtered with an ethanol solution with a concentration of 80% to 90%, and dried to obtain modified corn straw powder.

[0027] 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, mix 0.1-0.2 parts of ammonium cerium nitrate and 0.225-0.64 parts of HNO 3 Dissolve in 5 parts of water and...

Embodiment 2

[0031] The preparation method of 1 and 2 is the same as that of Example 1. In the preparation of nutrient water-absorbing resin, adjust urea: potassium chloride: magnesium sulfate: zinc sulfate: sodium borate: paclobutrazol=4: 1.5: 0.1: 0.02: 0.02: 0.02 solution soaking After 7-12 hours, a nutritional water-absorbent resin containing 33% of N, 13.9% of K, 0.17% of Mg, 0.080% of Zn, 0.074% of B and 0.35% of paclobutrazol was obtained. Preparation of slow-release, water-retaining, high-efficiency seedling-raising paper: Spray the nutritional water-absorbing resin prepared above on appropriate paper, and then cover with a layer of cotton pulp soft paper, and dry to obtain slow-release, drought-resistant, saline-alkali-resistant lawn paper b.

Embodiment 3

[0033]The preparation method of 1 and 2 is the same as that of Example 1. In the preparation of nutrient water-absorbing resin, adjust urea: potassium sulfate: zinc sulfate: sodium borate: paclobutrazol = 4: 1.8: 0.1: 0.02: 0.02: 0.02: soak in solution for 7 to 12 hours After that, a nutritional water-absorbent resin containing 31% of N, 13.6% of K, 0.16% of Mg, 0.076% of Zn, 0.059% of B and 0.34% of paclobutrazol was obtained. Preparation of slow-release, water-retaining, high-efficiency seedling-raising paper: apply the nutritional water-absorbing resin prepared above evenly on appropriate paper, and then cover with a layer of cotton pulp soft paper, and dry to obtain slow-release, drought resistance, and salt-alkali tolerance. Lawn paper C.

Abstract

The invention discloses slow-release, anti-drought and salt-tolerant lawn paper and a preparation method thereof. The method is characterized by comprising the following steps: using plant straws as main materials, processing the plant straws into gel through modification and ultrasonic treatment; adding nutrient solution into the gel for soaking to prepare nutrient absorbent resin, spraying the nutrient absorbent resin to paper, covering a layer of cotton pulp soft paper and drying, thereby obtaining the slow-release, anti-drought and salt-tolerant lawn paper. The lawn paper is suitable for any kind of soil, and can reduce the grass planting workload and also the conventional cumbersome process with soil fertilizers. The operation is simple, and the lawn paper is breathable and water-permeable and can not be bonded with the foundation. When the lawn paper is used, the grass planting environment is acidic with good ventilation, nutrients needed in each growth stage of the grass can be released slowly, and the grass with thick and strong roots can be obtained. Therefore, the lawn paper is suitable for growth of roof greening plants, lawn greening plants, greening plants for the saline-alkali soil and the like.

Description

technical field [0001] The invention relates to a slow-release, drought-resistant, saline-alkali-resistant lawn paper and a preparation method thereof. Specifically, it uses a composite water-absorbing resin prepared from plant straw as the main body, and can be used in the growth process of plants such as roof greening plants and lawn greening plants. It has obvious effects of slow release, drought resistance, and salt and alkali tolerance, and can continuously supply nutrients required by greening plants at various stages. Background technique [0002] The production and utilization of turf has a long history. As a way of urban landscaping, the construction of turf has its special ecological function and ornamental value, especially the urban open space dominated by ornamental turf, which is more and more popular and favored by people. Lawn plays an important role in dust prevention, soil and water conservation, air purification and increasing vegetation, especially for ex...
