Embodiment 1

[0021] A method for preparing a plant nutrient that prevents plant leaves from turning yellow and falling leaves is as follows: step 1: preparation of seaweed polysaccharides, fresh seaweeds are washed to remove impurities, squeezed and dehydrated to a water content of 50%, freeze-thawed twice, and the The fresh seaweed after freezing and thawing is put into the reaction kettle, and water accounting for 10 times the weight of the seaweed is added; protease of 1% of the dry weight of the seaweed is added, and the pH is adjusted to 7.0, stirred and extracted at 30°C for 2 hours, followed by centrifuged extraction, After concentrating the supernatant under reduced pressure, add 2 times the amount of 95% ethanol, place it at 3°C ​​for 10 hours and then filter it. After filtering, the filter cake is washed 3 times with absolute ethanol and dried to obtain seaweed polysaccharide;

[0022] Step 2: Mix 10 parts of seaweed polysaccharide, 1 part of mineral element, 5 parts of sugar resi...

Embodiment 2

[0027] A preparation method of a plant nutrient that prevents plant leaves from turning yellow and falling leaves is as follows: Step 1: preparation of seaweed polysaccharides, fresh seaweeds are washed to remove impurities, squeezed and dehydrated to a water content of 60%, freeze-thawed 3 times, and take the The fresh seaweed after freezing and thawing is put into the reaction kettle, and water accounting for 15 times the weight of the seaweed is added; protease of 5% of the dry weight of the seaweed is added, and the pH is adjusted to 7.0, stirred and extracted at 45°C for 3 hours, followed by centrifuged extraction, After concentrating the supernatant under reduced pressure, add 3 times the amount of 95% ethanol, place it at 8°C for 12 hours, and then filter it. After filtering, the filter cake is washed 3 times with absolute ethanol, and dried to obtain seaweed polysaccharide;

[0028] Step 2: Add 20 parts of seaweed polysaccharide, 5 parts of mineral elements, 10 parts of...

Embodiment 3

[0033] A preparation method of a plant nutrient that prevents plant leaves from turning yellow and falling leaves is as follows: Step 1: preparation of seaweed polysaccharides, fresh seaweeds are cleaned and decontaminated, squeezed and dehydrated to a water content of 55%, freeze-thawed 3 times, and take the The fresh seaweed after freezing and thawing is put into the reaction kettle, and water accounting for 12 times the weight of the seaweed is added; protease of 3% of the dry weight of the seaweed is added, and the pH is adjusted to 7.0, stirred and extracted at 38°C for 3 hours, followed by centrifuged extraction, After concentrating the supernatant under reduced pressure, add 3 times the amount of 95% ethanol, place it at 7°C for 11 hours and then filter it. After filtering, the filter cake is washed 3 times with absolute ethanol and dried to obtain seaweed polysaccharide;

[0034] Step 2: Mix 15 parts of seaweed polysaccharide, 8 parts of urea, 25 parts of potassium nitr...

Abstract

The invention discloses a plant nutrient for preventing plant leaves from yellowing and falling. The plant nutrient is prepared from the following raw materials in parts by weight: 10-20 parts of algal polysaccharides, 5-10 parts of urea, 20-30 parts of potassium nitrate, 1-5 parts of mineral elements, 5-10 parts of candy pomace, 1-5 parts of a compound enzyme preparation, 1-3 parts of a compound microbial agent, 15-20 parts of humate, 1-5 parts of bamboo vinegar, 1-5 parts of an additive and 1-5 parts of 6-benzylaminopurine. The algal polysaccharides are added into the plant nutrient, so the loss of dielectrics in plant cells is reduced, and good stress-resistant and antiviral effects are achieved; the fulvic acid is added to promote the absorption of roots, stems and leaves of plants and promote the growth of the plants; the potassium nitrate and the 6-benzylaminopurine are cooperatively used, so conductivity can be reduced, the content of chlorophyll is increased, decomposition of chlorophyll is inhibited, and the leaves of plants are prevented from yellowing and falling; and bamboo vinegar is added, so a sterilization effect is achieved, and the effects of promoting reproduction of microorganisms in soil and improving fertility are achieved.

Description

technical field [0001] The invention relates to a plant nutrient that prevents plant leaves from turning yellow and falling, and specifically relates to the technical field of plant nutrient preparation. Background technique [0002] The nutrient is a new type of nutrient synthesized by using the environmental biological ecological symbiosis technology and the principle of mycorrhizal symbiosis through biological fermentation, chemical chelation, physical activation and other processes. Different crops require different nutrient formulations. [0003] Seaweed polysaccharide is a kind of natural polysaccharide extracted from marine algae. After being absorbed by plants, it can increase the content of soluble polysaccharide in cells, increase the concentration of cell protoplasm, increase the viscosity, enhance elasticity, improve the water absorption and water retention capacity of cells, and maintain hydrolysis. The activity and stability of enzymes, proteases, esterases and...
