Embodiment 1
[0020] Choose mature and tall tomato stalks, soak them in tap water, wash them to remove soil and dust, wash them with distilled water, and dry them at 80°C to constant weight; grind the dried tomato stalks into powder, and select Pass through a 60-mesh sieve to collect the powder; weigh 50 g of the obtained powder and soak it in deionized water, add 2 mL each of the activated 0.01 mol / L amylase solution and protease solution, react at 35-50 °C for 1 hour, and then add 10mL of 0.05mol / L KOH solution, react for 50 minutes, and then use H 2 SO 4 Neutralize the solution, filter the neutralized liquid, and then dry it; mix the dried powder and urea in a mass ratio of 1:1, then re-immerse in deionized water, react at 50°C for 6 hours, filter, Afterwards, wash with deionized water three times to remove residual ionic liquid, and then wash with 95% alcohol twice, after washing, put it into an electric heating constant temperature drying oven at 50°C to dry to obtain the tomato straw...

[0022] Choose mature and tall tomato stalks, soak them in tap water, wash them to remove soil and dust, wash them with distilled water, and dry them at 80°C to constant weight; grind the dried tomato stalks into powder, and select Pass through a 60-mesh sieve to collect the powder; weigh 50 g of the obtained powder and soak it in deionized water, add 2 mL each of the activated 0.05 mol / L amylase solution and protease solution, react at 35-50 ° C for 2 hours, and then add 10mL of 0.1mol / L KOH solution, react for 50 minutes, and then use H 2 SO 4 Solution neutralization. Filter the neutralized liquid, and then dry it; mix the dried powder and urea in a mass ratio of 1:1, then re-immerse in deionized water, react at 50°C for 8 hours, filter, and then use deionized Wash with water for 3 times to remove residual ionic liquid, and then wash with 95% alcohol for 2 times. After washing, put it into an electric heating constant temperature drying oven at 50°C to dry to obtain the tom...
Embodiment 3
[0024] Choose mature and tall tomato stalks, soak them in tap water, wash them to remove soil and dust, wash them with distilled water, and dry them at 80°C to constant weight; grind the dried tomato stalks into powder, and select Pass through a 60-mesh sieve to collect the powder; weigh 100 kg of the resulting powder and put it into a 3-ton sanitary storage tank, and inject an appropriate amount of deionized water into the tank, add 2 mL each of the activated 0.05mol / L amylase solution and protease solution, and React at 50°C for 2 hours, then add 5L of 0.1mol / L KOH solution, react for 1 hour, and then use H 2 SO 4 Neutralize the solution, filter the neutralized liquid with a plate-and-frame compressor, and then dry it; mix the dried powder and urea at a mass ratio of 1:1, put it into a 3-ton sanitary tank, and inject it into a deionized tank water, kept at 50°C for 8 hours, filtered, washed with deionized water 4 times to remove residual ionic liquid, and dried at 50°C afte...
