Problems solved by technology

[0003] In the late stage of rice filling, the ability of roots to absorb nutrients declines, and insufficient nutrient and water supply leads to weakened leaf photosynthesis and premature leaf aging, resulting in insufficient filling of middle and weak grains and low seed setting rate, which seriously affects rice yield.

Embodiment 1

[0029] The raw materials for the production of rice functional foliar fertilizer include: 15 parts of boric acid, 22 parts of zinc sulfate heptahydrate, 45 parts of magnesium sulfate heptahydrate, 5 parts of ferrous sulfate, 4 parts of copper sulfate pentahydrate, 4 parts of manganese sulfate , 7 parts of urea, 7 parts of potassium sulfate, 10 parts of EDTA-Ga, 2 parts of citric acid, 2 parts of sodium nitrophenolate, 1 part of Tween 80, and 42 parts of compound amino acids.

[0030] The preparation method comprises the following steps:

[0031] Step (1): Add boric acid into the container according to the mass parts, stir to make it completely dissolve, and use it as mother liquor A;

[0032] Step (2): Dissolving zinc sulfate, magnesium sulfate, iron sulfate, copper sulfate and manganese sulfate one by one with 1 / 3 mother liquor A according to the mass parts, and then using the remaining mother liquor A to dissolve the compound amino acid, and then mixing into solution B;

Embodiment 2

[0036] The raw materials for the production of rice functional foliar fertilizer include, by weight, 16 parts of boric acid, 21 parts of zinc sulfate heptahydrate, 47 parts of magnesium sulfate heptahydrate, 5 parts of ferrous sulfate, 4 parts of copper sulfate pentahydrate, and 3 parts of manganese sulfate , 6 parts of urea, 7 parts of potassium sulfate, 9 parts of EDTA-Ga, 2 parts of citric acid, 2 parts of sodium nitrophenolate, 801 parts of Tween, 40 parts of compound amino acids.

[0037] The preparation method comprises the following steps:

[0038] Step (1): Add boric acid into the container according to the mass parts, stir to make it completely dissolve, and use it as mother liquor A;

[0039] Step (2): using 1 / 2 mother liquor A to dissolve zinc sulfate, magnesium sulfate, iron sulfate, copper sulfate and manganese sulfate one by one according to the mass parts, then use the remaining mother liquor A to dissolve the compound amino acid, and then mix it into solution B...

Embodiment 3

[0043] The rice functional foliar fertilizer prepared by using Examples 1 and 2 is applied in the test field, and at the full heading stage of rice, the formula volume ratio of Example 1 and Example 2 is used to spray evenly on rice leaves with a volume ratio of 50-100 times. noodle. Spraying once, the effect is shown in Table 1 and Table 2.

Abstract

The invention provides a rice functional foliage fertilizer formulation and a preparation method and application thereof. The rice functional foliage fertilizer formulation comprises 15-20 parts of boric acid, 20-25 parts of zinc heptahydrate sulfate, 45-50 parts of magnesium heptahydrate sulfate, 5-10 parts of ferrous sulfate, 3-5 parts of copper sulfate pentahydrate, 3-5 parts of manganese sulfate, 5-7 parts of urea, 5-8 parts of potassium sulfate, 10 parts of EDTA-Ga, 1-3 parts of citric acid, 1-3 parts of compound sodium nitrophenolate, 1-2 parts of Tween-80 and 40-45 parts of compound amino acid. The foliage fertilizer formulation is mainly prepared according to nutrients needed for later-stage growth of rice correspondingly, and yield can be increased by more than 5% after the formulation is applied for one time.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a rice functional foliar fertilizer formula and a preparation method thereof Background technique [0002] my country is the largest rice producer in the world, with a rice planting area of ​​30,311.7 thousand hectares. The population whose staple food is rice accounts for about 65% of the total population. At present, the compound multi-element foliar fertilizers on the market are mostly used for cash crops such as vegetables, fruit trees and peanuts. Few of them are specially applied to field crops, and even fewer are used for rice. Most of the foliar fertilizers used on rice are very primitive and simple inorganic salts, such as potassium dihydrogen phosphate and urea. Even if there are alternative multi-element foliar fertilizers, they are general-purpose products suitable for field crops, not rice-specific products. [0003] In the late stage of rice filling, the abilit...
