Embodiment 1

[0034] Embodiment 1: Preparation of chelated copper

[0035] Take 5kg of copper sulfate and 12kg of amino acid in the reaction tank. When the chelating temperature is 60°C, add copper sulfate to the amino acid in batches, stir for 1 hour after adding, add NaOH solution dropwise to adjust the pH value to 8.0-8.5 for chelation Reaction, measure chelation rate with EDTA method, when chelation rate reaches 7.99%, it is the end point of chelation reaction, oven dry prepares chelated copper 10kg.

Embodiment 2

[0036] Embodiment 2: prepare chelated copper

[0037] Take 5kg of copper sulfate and 12kg of amino acid in the reaction tank. When the chelating temperature is 70°C, add copper sulfate to the amino acid in batches, stir for 1 hour after adding, add NaOH solution dropwise to adjust the pH value to 8.0-8.5 for chelation Reaction, measure chelation rate with EDTA method, when chelation rate reaches 7.99%, it is the end point of chelation reaction, oven dry prepares chelated copper 10kg.

Embodiment 3

[0038] Embodiment 3: prepare chelated copper

[0039] Take 5kg of copper sulfate and 12kg of amino acid in the reaction tank. When the chelating temperature is 80°C, add copper sulfate to the amino acid in batches, stir for 1 hour after adding, add NaOH solution dropwise to adjust the pH value to 8.0-8.5 for chelation Reaction, measure chelation rate with EDTA method, when chelation rate reaches 7.99%, it is the end point of chelation reaction, oven dry prepares chelated copper 10kg.

Abstract

The invention discloses a foliar fertilizer for increasing the seed setting rate of hybrid rice, which contains (diethyl aminoethyl hexanoate) DA-6, growth hormones, Mepiquat, penetrating agents and fillers. The foliar fertilizer can also contain water-soluble silicon, zinc compounds, copper compounds and surfactants. A preparation method of the foliar fertilizer comprises the following steps of: (1) mixing growth hormones and Mepiquat with alcohol and dissolving, adding penetrating agents and fillers, stirring, and drying and grinding at a temperature below 40 DEG C; and (2) mixing DA-6 with the resulting mixture from the step (1), adding the rest fillers, and thoroughly stirring to obtain the final product of foliar fertilizer wettable powder. A method for applying the foliar fertilizer for increasing the seed setting rate of hybrid rice comprises the following steps of: (1) dissolving the foliar fertilizer in water; and (2) spraying the foliar fertilizer liquid to leaves of rice plants by using a spraying device. The foliar fertilizer reduces seed setting physiological disorders in hybrid rice and reduces the impact of external environment on seed setting. The foliar fertilizer and the preparation and the application methods of the foliar fertilizer have a simple production process and can increase the seed setting rate of hybrid rice.

Description

technical field [0001] The invention relates to a crop fertilizer, a preparation method and an application method, in particular to a foliar fertilizer applied to rice planting and production, a preparation method and an application method. Background technique [0002] Rice is one of the most important food crops in my country and has an important strategic position in my country's food production. Most of the rice producing areas in my country are hybrid rice. However, the low seed setting rate of hybrid rice restricts the increase of rice yield. The low seed setting rate of hybrid rice and other obstacles to fruiting are affected by the external environment and the physiological characteristics of hybrid rice, such as early rice low cold, high temperature and The influence of the cold dew wind in late rice and the premature senescence of the roots and leaves, the excess of large ears and insufficient fruiting, and the uneven filling of strong and weak seeds caused the incr...
