Description
Technical Field
The invention belongs to the technical field of agricultural cultivation and planting, and relates to an agricultural composition containing lecithin and choline chloride.
Background
The chemical control mode is widely adopted in the agricultural production process to regulate the growth of crops and improve the yield and quality of the crops. With the use of a large amount of plant growth regulators, the yield of crops is gradually improved. However, in recent years, due to improper use of plant growth regulators, the yield of some crops is not increased any more, but tends to be decreased, and particularly, the overground part of root crops such as peanuts, potatoes, sweet potatoes and the like are excessively flourished, and the yield of underground roots is very low. Improper application of the plant growth regulator can result in over-vigorous vegetative growth of root crops, vigorous growth of overground parts of plants, consumption of a large amount of nutrients, and prolonged vegetative growth period, which leads to reduced nutrition for reproductive growth, greenness and late maturity of crops, and reduced yield.
Lecithin is a phospholipid-containing substance composed of glycerol, choline, phosphoric acid and fatty acid, and is commonly present in egg yolk, animal brain, soybean, corn, cotton seed and other resources. The lecithin is composed of phosphatidylcholine or choline phosphoglycerate, which has a triglyceride molecule in which phosphoric acid is combined with choline. The lecithin molecule structure contains hydrophilic phosphate group and lipophilic fatty acid group, so it can be absorbed by plant to raise its disease-resisting capacity. The hydrophilic group of lecithin can keep plant leaves moist and prevent the invasion of germs, thereby inhibiting the growth and reproduction of the plants. Meanwhile, lecithin also has the effect of preventing and treating plant diseases and insect pests of crops such as vegetables, rice and the like.
Choline chloride is known as 2-hydroxyethyl trimethylamine chloride, and is a broad-spectrum plant growth regulator. The choline chloride is used for soaking or spraying seedlings, can promote the rooting, the germination and the cultivation of strong seedlings of crops, and can improve the yield and the quality. Research shows that choline chloride seed soaking has certain promotion effect on improving the activity of the tobacco root system, which is beneficial to enhancing the nutrient absorption capacity of the root system and cultivating strong seedlings. Choline chloride is also a photosynthetic promoter, can promote the growth of cotton seedlings after seed soaking treatment, improve the photosynthetic rate of cotton, and can relieve dehydration damage and membrane lipid peroxidation of wheat seedlings caused by salt stress, thereby enhancing the stress resistance of cotton and wheat seedlings.
The amino-oligosaccharin is also called as agricultural special chitosan oligosaccharide, is used as a novel environment-friendly biopesticide, can promote the growth of plants, induce and improve the resistance of the plants to diseases and insect pests, so that the application effect and mechanism of the amino-oligosaccharin are widely and deeply researched. The amino-oligosaccharin is used as a plant growth regulator, can activate plant cells, regulate and promote plant growth, improve stress resistance, enhance cold resistance, drought resistance and waterlogging resistance of crops, improve seed germination rate, strengthen seedlings, promote roots, improve absorption and utilization rate of the plants on fertilizers and moisture, and enhance stress resistance of the crops.
Patent CN111470910A discloses a growth regulator composition for citrus gonggan and a preparation method thereof, belonging to the field of crop plant growth regulators, comprising the following components: 4-8 parts of amino-oligosaccharin, 4-9 parts of methyl jasmonate, 1-3 parts of gamma-aminobutyric acid, 2-6 parts of brassinolide, 6-9 parts of sodium selenite, 6-9 parts of sodium selenate, 1-4 parts of a corn steep liquor fermentation extract, 0.3-0.8 part of stearamide, 0.1-0.5 part of lignosulfonate, 0.1-0.6 part of soybean lecithin and 0.8 part of polyethylene glycol-20000.1. Patent CN107410312A discloses a special regulator for rhizome crops, which is wettable powder or water dispersible granules prepared from prohexadione calcium, choline chloride, an auxiliary agent and a filler; every 100 parts by weight of the regulator comprises 1-50 parts of prohexadione calcium and 0.1-20 parts of choline chloride; when the regulator is wettable powder, the auxiliary agent consists of the following raw materials in parts by weight: 2-10 parts of a dispersing agent and 0.5-3 parts of a wetting agent; when the regulator is a water dispersible granule, the auxiliary agent consists of the following raw materials in parts by weight: 1-15 parts of dispersing agent, 0.5-8 parts of wetting agent, 0-10 parts of disintegrating agent and 0-8 parts of binder; the regulator disclosed by the invention can effectively regulate the growth of rhizome crops, control overground parts to grow, promote the enlargement and growth of underground parts, promote photosynthesis, improve the chlorophyll level of leaves, delay the senescence of plants, improve the yield and quality of crops, reduce the labor cost and improve the economic benefit. The active ingredients of the two patents comprise lecithin and choline chloride respectively, but the combined use of the lecithin and the choline chloride is not reported in the literature, and the function of the combined use of the lecithin and the choline chloride as a plant growth regulator in root crops is difficult to predict.
The conventional plant growth regulator for root crops mostly uses paclobutrazol, cycocel and the like, controls overgrowth of overground parts and simultaneously limits the growth of underground roots and stems. On the other hand, the fertilizer is used in a large amount for high yield, so that a large amount of elements in soil are enriched, trace elements are deficient, the utilization rate of the fertilizer is low, various physiological diseases are serious, and the yield is limited to be improved. The present inventors have conducted extensive studies to find an agricultural composition containing lecithin and choline chloride, which can promote the expansion of the rhizome of a rhizome crop, increase the yield of the root crop, and improve the quality of the root crop, and the composition is not disclosed in the known literature, and it is difficult for those skilled in the art to know the beneficial effects of the composition for regulating the growth of the root crop.
