Problems solved by technology

The main producing areas of my country's pears are mainly concentrated in the sandy loam areas in Northwest China, but in Northwest China and the ancient Yellow River area, the soil pH value is generally 7.5-8.0, which is weakly alkaline, and the iron in the soil is usually in the form of Fe 3+ The situation exists, and it is difficult for pear trees to effectively absorb and utilize
Long-term accumulation will lead to yellowing of pear tree leaves, and the growth of pear trees suffering from yellowing disease will be hindered, which will seriously affect the fruiting of pear trees and cause major economic losses
"Golden Pear" is a variety imported from abroad in China. It is loved by the general public for its tender and juicy flesh, high sugar content, and sweet taste. Due to the yellowing of the leaves, iron deficiency was very serious during the cultivation of "Golden Pear", and the yield decreased

Abstract

The invention belongs to the technical field of agricultural cultivation, and particularly relates to an anti-yellowing foliar fertilizer and a preparation method thereof. The anti-yellowing foliar fertilizer is prepared from, by weight, 0.05-0.3% of urea, 0.1-0.5% of monopotassium phosphate, 0.1-0.4% of ferrous sulfate, 0.3-0.8% of ethylene diamine tetraacetic acid, 0.01-0.05% of gibberellin andthe balance water. The foliar fertilizer can effectively make leaf surfaces of whangkeumbae suffering from yellowing green again, absorption and utilization of Fe3+ in soil are promoted, and the foliar fertilizer is convenient to use, low in cost, harmless to people and livestock and free of pollution and takes effect quickly.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to an anti-yellowing foliage fertilizer and a preparation method thereof. Background technique [0002] my country has a vast territory, and there are many kinds of fruits, among which pear is the most common fruit, and the planting area is relatively large. As early as 2012, the cultivated area of ​​pears in my country reached 108.9hm 2 , accounting for 70.0% of the world's pear tree cultivation area, the output is 17.073 million tons, reaching 69.0% of the world's total output, and it is still growing in recent years. The main producing areas of my country's pears are mainly concentrated in the sandy loam areas in Northwest China, but in Northwest China and the ancient Yellow River area, the soil pH value is generally 7.5-8.0, which is weakly alkaline, and the iron in the soil is usually in the form of Fe 3+ The situation exists, and it is difficult ...
