Abstract
The present invention provides a plant nutritional composition comprising a first nutrient and a second nutrient. The first nutrient comprises alginic acid, nitrogen, potassium, boron, copper, iron, manganese, zinc, a first development regulatory protein, a first induced interferon and a penetrant; the second nutrient comprises brassin, a second development regulatory protein, a second induced interferon, and an osmotic agent. The nutrient composition is used for promoting the growth of kiwi fruits, and is characterized in that a first nutrient is sprayed 20-25 days after flowers fall off from kiwi fruits, and a second nutrient is sprayed 50-55 days after flowers fall off from kiwi fruits, so that the yield increase effect is remarkable, the nutrient composition is safe and harmless, and the nutrient composition is suitable for mass production and long-term use.
Description
Technical Field
The invention belongs to the technical field of plant growth regulators, and particularly relates to a plant nutrient composition and application thereof.
Background
The kiwi fruit is a berry fruit originally produced in China, is rich in vitamins (C, B1, B2, B3, B5, B6, B9 and B A, E, K), minerals (calcium, iron, magnesium, phosphorus, potassium, sodium, zinc, copper, manganese and selenium) and nutrient substances such as energy, protein, fiber and the like, and is called 'king of fruit' due to extremely high comprehensive nutritional value. However, in actual production and cultivation, the weight of a single kiwi fruit is generally smaller due to the growth characteristics of the kiwi fruit, and at present, in order to increase the economic benefit of the kiwi fruit, an expanding agent is often used for improving the yield of the kiwi fruit.
The expanding agent is a general name of substances for stimulating cell division, mainly comprises forchlorfenuron and 6-benzylaminopurine, wherein the forchlorfenuron is also called CPPU or KT-30 and is commonly called as Daguoling, is a cytokinin plant growth regulator with higher biological activity, has cell division activity, and can enhance stress resistance and delay senility. The main physiological functions of the expanding agent are to promote cell division, enhance the competitive power of fruits on photosynthetic products, coordinate the relationship of nutrient sources, improve the organic nutrient condition in the fruits and promote fruit setting and fruit enlargement.
At present, the expanding agent is used and registered in many foreign countries, including world Kiwi fruit-New Zealand, the registered application range includes Kiwi fruit, grape, watermelon, melon, eggplant, tobacco and other crops. In China, forchlorfenuron produced by some enterprises is also registered for various crops such as kiwi fruits, and the forchlorfenuron is widely used because the yield increasing effect obviously brings abundant economic benefits to kiwi fruit growers. In recent years, the negative reports about the use of the expanding agent emerge endlessly, and the consumer's call for banning the expanding agent is higher and higher, mainly because the expanding agent is excessively used for dipping or spraying kiwi fruits in successive years, so that the reproductive growth and the vegetative growth of the fruit trees are unbalanced, the stress resistance of the trees is weakened, the fruits are deformed, the calyx heads are wide and thick, the fruit peels are rough, the fruit cores are thickened and enlarged, some fruits are even hollow, the fruit pulps are rough, the color is light, the flavor is lightened, and the like. In addition, forchlorfenuron belongs to a low-toxicity plant growth regulator, the residues of the forchlorfenuron are strictly limited in the United states, European Union and Korea, the forchlorfenuron residues in the kiwi fruits are limited to 0.05mg/kg according to the current national standard in China, and excessive use or human ingestion can cause certain influence on human health. Therefore, the application of the expanding agent on the kiwi fruits has advantages and disadvantages, many researchers are exploring reasonable application technologies, the advantages of increasing both production and income, advancing ripening, improving internal quality and the like of the expanding agent can be exerted, the defects of tree weakness, fruit malformation, low storage tolerance and the like can be reduced as much as possible, but no other matched commodities and technologies are sold in the market, the expanding agent only stays in a small-range test field, and the expanding agent is not popularized in a large area.
In order to solve the problems, the research on the plant nutrient composition which has low cost, high efficiency, good effect, no residue and can be sprayed is needed. As is known, liquid spray fruit swelling is a relatively energy-saving and efficient technology, so that research on commercialized liquid spray fruit swelling nutrient solution and application method suitable for large-area popularization is urgent to realize sustainable and healthy development of kiwi fruit industry.
