example 1

[0020] Example 1 The configuration of seaweed foliar fertilizer and its effect experiment on increasing the yield of tobacco leaves

[0021] The configuration process of seaweed foliar fertilizer is as follows:

[0022] 1. Weigh 2 grams of dried seaweed and cut it into small pieces of 1 cm square, and then pass through a pulverizer to obtain coarse seaweed powder with a diameter of 2 mm;

[0023] 2. The seaweed powder is further pulverized to a diameter of about 20-50 microns by means of an ultrafine pulverizer;

[0024] 3. Add the pulverized seaweed powder and 1 gram of compound amino acid powder to 4 mL of 1N phosphoric acid solution and keep it warm at 80°C for 12 hours for acidolysis;

[0025] 4. Adjust the pH of the mixed solution to 5.8 with ammonia water;

[0026] 5. Add metal salt mother liquor 5mL and rare earth mother liquor 0.5mL;

[0027] 6. Add water to adjust the mixed solution to 1 liter, and adjust the pH of the mixed solution to 5.8 with 6N sodium hydroxide...

Abstract

The present invention relates to agricultural technology, and is seaweed amino acid RE compound foliage fertilizer and its preparation process. The preparation process includes the following steps: 1. crushing seaweed into superfine seaweed powder; 2. adding seaweed powder and compound amino acid powder into 1-6N phosphoric acid or acetic acid solution and maintaining at 60-120 deg.c for 2-40 hr to acidolyze to obtain mixture solution of seaweed oligose, polypeptide and amino acid; 3. regulating the pH of the mixture solution to 5-7 with ammonia water, sodium hydroxide or lime water, and adding metal salt mother liquid and RE mother liquid; and 4. adding water and regulating pH to 5-7 with ammonia water, sodium hydroxide or lime water to obtain the compound foliage fertilizer. The compound foliage fertilizer can raise the photosynthesis efficiency of plant and promote plant growth.

Description

technical field [0001] The present invention relates to a fertilizer in the technical field of agricultural products and a preparation method thereof. Specifically, it relates to a seaweed amino acid rare earth compound foliage fertilizer prepared from seaweed, amino acid, rare earth and metal salts as main raw materials and its Preparation. Background technique [0002] Seaweed is widely used in health products, food and foliar fertilizer. The foliar fertilizer with seaweed as the main raw material can promote the healthy development of seeds, strengthen the roots, adjust and supplement the deficiency of trace elements, play a key role in the nutrition of plants, increase chlorophyll, bright flowers, achieve strong plants, and greatly increase the vitality of plants Improvement, helps to resist diseases and insect pests and natural drought resistance, fruit plump, sweetness increased. Seaweed extracts, amino acids, and rare earths all promote plant growth independently, a...
