Embodiment 1

[0064] Put 100g of industrial gelatin in a chemical reaction kettle, use 300mL of 6M hydrochloric acid, continuously reflux at 110-113°C for 12 hours, add 100mL, 50% NaNO dropwise at 45°C after cooling 2 , heat up to 70°C and react for 1 hour, then add 100mL, 6M HCl, vacuum concentrate the acid water to 1 / 5 of the original volume, the concentration temperature is 70°C, filter with glass fiber, and dilute the filtrate with water to Ph1-2 Between, add 20g active carbon dosage, boil decolorization 0.5 hour, after cooling, warm filter. The filtrate is adjusted to a pH value between 5-7 with KOH, and concentrated at 70° C. under vacuum to obtain a mixed solution of various amino acids and polypeptides. Then add 20g (dry weight) multi-element mixed powder (urea 5g, potassium dihydrogen phosphate 2g, boric acid 2g; edetate disodium 1.8g, manganese chloride 2g, calcium chloride 1g, magnesium sulfate 2g, sulfuric acid 2g of ferrous iron, 1g of zinc sulfate, 0.2g of copper sulfate, mix...

Embodiment 2

[0066] Put 100g of industrial gelatin in a chemical reaction kettle, use 200mL of 3M hydrochloric acid, continuously reflux at 110-113°C for 18 hours, add 25g of activated carbon after cooling, boil for 1 hour to decolorize, cool, then warm and filter. The filtrate is adjusted to a pH value between 5-7 with ammonia water, and concentrated at 70° C. under vacuum to obtain a mixed solution of various amino acids and polypeptides. Then add 15g (dry weight) multi-element mixed powder (same as in Example 1), 5g of phytosterol water dispersant powder (same as in Example 1), 0.5g of chamaejasma chromone and mix well.

Embodiment 3

[0068] Put 100g of industrial gelatin in a chemical reaction kettle, use 200mL of 6M hydrochloric acid, continuously reflux at 110-113°C for 10 hours, add 50g of activated carbon after cooling, and react at 80°C for 2 hours for decolorization. After cooling, warm and filter. The filtrate is adjusted to a pH value between 5-7 with KOH aqueous solution, and concentrated under vacuum at 70° C. to obtain a mixed solution of various amino acids and polypeptides. Then add 10g (dry weight) multi-element mixed powder (same as in Example 1), 10g of phytosterol water dispersant powder (same as in Example 1), 1g of chamaejasma chromanone and mix well.

Abstract

The invention discloses a composite fertilizer which is mainly prepared from amino acid mixture, various nutrient elements, phytosterol dispersant powder, synergist, stabilizer and penetrating agent. The composite fertilizer is a novel phytosterol foliar fertilizer which has the advantages of high efficiency, no toxicity and environment friendliness, not only can promote the growth of plants by over 10 percent, but also causes no environmental pollution.

Description

technical field [0001] The invention relates to a medicinal fertilizer and a preparation method thereof, in particular to a compound medicinal fertilizer and a preparation method thereof. Background technique [0002] Foliar fertilizers are widely used in agricultural production due to their characteristics of quick effect, high utilization rate, less dosage, simple application method and obvious yield increasing effect. In recent years, both at home and abroad have attached great importance to the production and application of foliar fertilizers. There are thousands of commercial foliar fertilizers in my country alone. But still do not have better, have the multifunctional compound type foliar fertilizers such as nutrition, plant growth regulation, desinsection and bacteriostasis. Therefore, we have developed a series of multifunctional compound foliar fertilizers, and Beinong No. 3 foliar fertilizer is one of them. The development and application of this variety has enric...
