Embodiment Construction

[0017] 1. Raw material preparation

[0018] Arginine (C 6 h 14 N 4 o 2 ≥98.5%), proline (C 5 h 9 NO 2 ≥99%), lysine (C 6 h 14 N 2 o 2 ≥99%), glycine (C 2 h 5 NO 2 ≥98.5%), glutamic acid (C 5 h 9 NO 4 ≥98.5%), leucine (C 6 h 13 NO 2 ≥98.5%), threonine (C 4 h 9 NO 3 ≥98.5%), aspartic acid (C 4 h 7 NO 4 ≥98.5%), alanine (C 3 h 7 NO 2 ≥98.5%), phenylalanine (C 9 h 11 NO 2 ≥98.5%), zinc sulfate (Zn≥22.05%), manganese sulfate (Mn≥31.8%), copper sulfate (Cu≥24.90%), ferrous sulfate (Fe≥19.7%), and water for later use.

[0019] 2, the preparation process (the following according to the mass parts)

[0020] (1) Measure 918.9 parts of water into the reactor and heat to 80°C;

[0021] (2) According to arginine: proline: lysine: glycine: glutamic acid: leucine: threonine: aspartic acid: alanine: phenylalanine mass ratio is 2:4: The ratio of 1:4:4:5:2:3:4:4 accurately weighs various amino acid raw materials, which are 6.2 parts of arginine, 12.3 parts of pr...

Abstract

The invention discloses foliar fertilizer for improving crisp pear quality and an application method thereof. The pear foliar fertilizer is prepared from arginine, proline, lysine, glycine, glutamic acid, leucine, zinc, manganese, copper, iron, threonine, asparaginic acid, alanine and phenylalanine, wherein arginine and proline have a promoting effect on pear growth development; lysine, glycine, glutamic acid, leucine, the zinc, the manganese, the copper and the iron have a promoting effect on pear photosynthesis; threonine, asparaginic acid, alanine and phenylalanine have a promoting effect on pear stress resistance. The application method of the pear foliar fertilizer comprises the steps: mixing with water to dilute the pear foliar fertilizer spraying 2 to 4 times in a fruit expanding period, spraying to the front and back sides of leaves when no wind, no rain and no burning sun and spraying until the leaves are wet in each spraying. When the fertilizer disclosed by the invention isused, pear photosynthesis and metabolism are promoted, the sugar content and the vitamin content of crisp pears are better improved, and pear quality is improved.

Description

technical field [0001] The invention relates to a chemical fertilizer and an application method thereof, in particular to a foliage fertilizer for improving the quality of pears and an application method thereof. Background technique [0002] Dangshan County, Anhui Province is located in the old course of the Yellow River, and is known as the "Pear Capital" because of its rich crisp pears. Dangshan crispy pear is a product of China's national geographical indication. It is the main pillar industry for increasing farmers' income in Dangshan County. It has a long history of cultivation and is the first of the three traditional Chinese pears. Thin and juicy, crisp and sweet, it is well-known both at home and abroad. However, the price of Dangshansu pears is significantly lower than the average price of branded pears in the market, and the export volume is also very small. The main factors restricting the price and export of Dangshan pears include rough skin, uneven fruit size...
