Example Embodiment

[0025] Example 1

[0026] 1. Modification of corn stalks: crush corn stalks into powder at room temperature, and pass through 80-200 mesh sieve. Take 10-50 parts by mass of corn stover powder, 100-200 parts of ethanol, 20-100 parts of 50% NaOH deionized aqueous solution, stir and react at 25-40 degrees for 1~2h, then add 15~70 Parts of chloroacetic acid and 45 parts of absolute ethanol, stirred for 1 to 2 hours at 60-80 degrees, neutralized the reaction solution and filtered, washed and filtered with 80%-90% ethanol solution, dried to obtain modified corn Straw powder.

[0027] 2. Ultrasonic treatment of corn stalks: Take 2 parts of the modified corn stalk powder of step 1 and add 30 parts to 100 parts of water to fully dissolve them, and ultrasonic treatment for 4 to 7 minutes to form a modified cellulose solution. At room temperature, mix 0.1~0.2 parts of cerium ammonium nitrate and 0.225~0.64 parts of HNO 3 Dissolve in 5 parts of water and add to the modified cellulose solutio...

[0030] Example 2

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

[0033] The preparation method of 1 and 2 is the same as that of Example 1. Adjust urea: potassium sulfate: zinc sulfate: sodium borate: paclobutrazol = 4: 1.8: 0.1: 0.02: 0.02: 0.02: soaking in solution for 7-12 hours in the preparation of nutritional water-absorbing resin Then, a nutritive 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 is obtained. Preparation of slow-release, water-retaining, and high-efficiency seedling paper: evenly coat the nutrient-absorbent resin prepared above on a suitable paper, then cover with a layer of soft cotton pulp paper, and dry it to obtain slow-release, drought-resistant, and salt-resistant 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...
