Problems solved by technology

[0003] Some orchards with rich management experience and proper preventive measures can control the early leaf fall, but most of the orchards are still suffering from early leaf fall due to various conditions and insufficient technical reserves.
Moreover, in the orchards where early leaf defoliation occurs, the fruit quality generally declines, which se

Embodiment 1

[0017] Example 1 Preparation of liquid fertilizer

[0018] Test time: 2012

[0019] Location: Lishui Plant Science Base, Jiangsu Academy of Agricultural Sciences.

[0020] Taking the preparation of 1L preparation as an example, liquid fertilizer formula: 2 g water-soluble soybean isoflavones, 5 g aminochitooligosaccharides, 100 g potassium nitrate, 3 g amino acid chelated copper, 20 g polyglutamic acid and 20 g potassium fulvic acid , Tween-20 50 g, the balance is water.

[0021] Dissolve water-soluble soy isoflavones, aminochitooligosaccharides, and potassium nitrate in 600mL of water in proportion and stir evenly, then add amino acid chelated copper, polyglutamic acid, and potassium fulvic acid in sequence. After the dissolution is complete, add Tween -20, stir evenly, add water to 1L, and form a liquid fertilizer after fully stirring, the active ingredient content of which is about 130g / L.

Abstract

The invention discloses a liquid fertilizer for preventing early leaf fall of pear trees, and a preparation method and an application thereof. The liquid fertilizer comprises water-soluble isoflavones, amino chitosan oligosaccharides, potassium fulvate, copper amino acid chelate, potassium nitrate, an assistant and water. The preparation method comprises the following steps: respectively dissolving the water-soluble isoflavones, amino chitosan oligosaccharides and potassium nitrate in 600mL of water, stirring, adding copper amino acid chelate, polyglutamic acid and potassium fulvate, completely dissolving, adding tween-20, uniformly stirring, and adding water to 1L. The liquid fertilizer diluted with water can be used to prevent the early leaf fall of pear trees, is in favor of realizing disease prevention and high yield of fruit trees, improves the quality of fruits, and increases the economic benefit.

Description

technical field [0001] The invention relates to the field of fertilizer preparation, in particular to a liquid fertilizer for preventing early defoliation of pear trees, a preparation method and application thereof. Background technique [0002] Early defoliation is one of the major problems that plague the development of fruit tree industries such as apples and pears. The tree body weakness, quality decline, yield decline and serious disease occurrence caused by early defoliation every year seriously affect the production and economic benefits of orchards. The early defoliation of fruit trees There are many inducing factors and the inducing mechanism is complex, such as physiological leaf defoliation: tree body nutrition imbalance, or partial application of chemical fertilizers instead of organic fertilizers, resulting in nutrient disconnection, causing a large number of fallen leaves, or unreasonable tree structure, poor ventilation and light transmission, tree The deteri...
