Embodiment 1

[0017] The applicant conducted an experiment in Boshida Apple Orchard, Guanli Town, Qixia City, Yantai City, Shandong Province. The test material is 8-year-old red Fuji apple / M26 / octopus, the distance between plants and rows is 2.0m×4.0m, and the test site is 20 mu. Before falling leaves in autumn 2014, according to the scheme of this invention, the tree body is sprayed with foliage fertilizer before falling leaves in autumn, and 2 processes are established: processing 1: special leaf fertilizer and application thereof before falling leaves of apples in autumn in autumn of the present invention: according to the following Proportions by weight: 15 parts of potassium fulvic acid, 21 parts of urea, 5 parts of borax, 4 parts of zinc sulfate, 10 parts of EDTA chelated calcium, 9 parts of magnesium sulfate, 3 parts of ferrous nitrate, 2 parts of ammonium molybdate , 2 parts of paclobutrazol, 2 parts of sodium selenite, 2 parts of Tween 80#, 11 parts of glucose, 14 parts of compound...

Embodiment 2

[0022] From 2014 to 2016, experiments of the present invention were carried out in Fuji apple orchards in apple producing areas such as Laishan Town, Laishan District, Shandong, Guanli Town, Qixia City, Yiyuan County, Shandong, Xingcheng Fruit Tree Institute Base, Liaoning, Baoding, Hebei, etc., and achieved remarkable results. Effect, increase the economic benefit of the fruit farmer, comprehensive 52 apple orchards 3 years test result statistics show, after applying the present invention, tree body storage nutrition level has improved 31%, the second year flower bud quality improves significantly, and first-class fruit rate improves 21% percentage point, the sugar content increased by 1.5 units, the growth of the tree was obviously robust, the incidence of diseases was reduced, and the economic benefit increased by 560 yuan / mu.

Abstract

The invention relates to foliar fertilizer specially for apples before defoliation in autumn and a use thereof. The foliar fertilizer comprises, by weight, 13 to 17 parts of potassium fulvate, 19 to 22 parts of urea, 3 to 5 parts of borax, 3 to 5 parts of zinc sulfate, 8 to 12 parts of EDTA chelated calcium, 8 to 12 parts of magnesium sulfate, 2 to 4 parts of ferrous nitrate, 2 to 4 parts of ammonium molybdate, 2 to 3 parts of paclobutrazol, 1 to 2 parts of sodium selenite, 1 to 2 parts of Tween 80#, 8 to 12 parts of glucose and 10 to 15 parts of compound amino acids. The 1000-fold dilute foliar fertilizer is sprayed to the leaves for the first time in about 15 days before the leaves of the fruit trees fall off, and the 500-fold dilute foliar fertilizer is sprayed to the leaves for the second time in about 7 days before the leaves of the fruit trees fall off. The foliar fertilizer is used before 9:00 am or after 3:30 pm in the sunny day. The foliar fertilizer can effectively improve the leaf functions, promote reflux of the leaf nutrients and increase the nutrient storage of the tree. The foliar fertilizer has the advantages of simple use method and remarkable effects.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of fertilizer production, in particular to a special foliage fertilizer for apples before leaf fall in autumn and its application. [0003] (2) Background technology [0004] At present, in my country's apple production, the insufficient quantity of stored nutrients in the tree body is one of the main limiting factors affecting high yield and high efficiency. The budding, flowering, fruit setting, new shoot growth, young fruit expansion and root growth of apple trees in spring mainly depend on the stored nutrients of the tree body in the previous year. Insufficient stored nutrients will first affect the quality of flower buds, resulting in a decrease in fruit setting rate and slow expansion of young fruit, resulting in a decrease in yield and quality in the current year; secondly, insufficient growth of spring shoots, excessive growth of autumn shoots, and poor differentiation of flower buds will a...
