Embodiment 1

[0013] Add 400g of carboxymethyl chitosan, 2000g of humic acid, 800g of fulvic acid, 10g of phosphorus pentoxide, 20g of potassium hydroxide, 4g of boric acid, 3g of ethylenediaminetetraacetic acid, 2g of zinc sulfate heptahydrate in 1L of water , manganese sulfate monohydrate 1 g, glycine 20 g, glutamic acid 30 g, serine 10 g, lysine 15 g; mix well and encapsulate.

Embodiment 2

[0015] Add 350g carboxymethyl chitosan, 1500g humic acid, 900g fulvic acid, 20g phosphorus pentoxide, 15g potassium hydroxide, 1 g boric acid, 1 g ethylenediaminetetraacetic acid, 2 zinc sulfate heptahydrate in 1L water g, 3 g of manganese sulfate monohydrate, 50 g of glycine, 40 g of glutamic acid, 15 g of serine, and 10 g of lysine, mix evenly and seal.

Embodiment 3

[0017] The specific formula is the same as in Example 2, but 300ml of the aqueous extract of Chinese medicinal materials is added to 1L of water. The preparation method of the aqueous extract of Chinese medicinal materials is as follows: cut 18g Tripterygium wilfordii, 15g Changpu and 12g Lemongrass into small pieces and then grind to obtain ground powder. made by filtration.

[0018] The using method of liquid fertilizer of the present invention is as follows:

[0019] 1. Fertilize by irrigation

[0020] After mixing 1 kg of the fertilizer prepared in Example 1 into 30-60 kg with water, fertilize the transplanted tomato or cucumber seedlings, and use 10-50 ml of fertilizer for one seedling. The result of using 500 strains shows that, for the same seedlings, using the fertilizer of the present invention, the survival rate after transplantation is 18% higher than that of the non-application group, and the growth rate of the seedlings is obviously improved.

Abstract

The invention relates to an organic liquid fertilizer containing chitosan. The organic liquid fertilizer comprises the chitosan, humic acid, fulvic acid, phosphorus pentoxide, potassium hydroxide, boric acid, edetic acid, zinc sulphate, manganese sulfate monohydrate, glycine, glutamic acid, serine and lysine. Aqueous extract of traditional Chinese medicines is added into the organic liquid fertilizer. As various marine bioactive ingredients such as the chitosan are added into the organic liquid fertilizer, the organic liquid fertilizer can be used for culturing a great quantity of effective microbial communities of actinomycetes and the like within short time after being applied to soil. Antibiotics and other substances secreted from the effective microbial communities can inhibit harmful microbial communities of pythium aphanidermatum, rhizoctonia and the like, and thus a microbial environment of the soil can be improved rapidly. The chitosan also can be used for accelerating the growth of root systems and the combination of the root systems and the soil. In addition, as the aqueous extract with insecticidal efficacy of the traditional Chinese medicines is added into the organic liquid fertilizer, plant diseases and insect pests of leaf surfaces can be effectively reduced when the fertilizer is applied to the leaf surfaces.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer processing, and in particular relates to an organic liquid fertilizer containing chitosan. Background technique [0002] my country is a large agricultural country, and the increase of agricultural production and income cannot be separated from the application of chemical fertilizers. However, while the use of chemical fertilizers increases the yield of crops, it also brings disadvantages such as soil compaction and residues in agricultural products. Although the use of farmyard manure can overcome problems such as soil compaction and chemical residues, firstly, the amount of farmyard manure is too small to meet the requirements of large-scale use; secondly, traditional farmyard manure will cause pathogenic microorganisms and parasites ( eggs) dispersal, and issues such as nitrogen loss. Therefore, it is very important to find new bio-organic fertilizers that can partially or complet...
