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.
[0044] Test location: Experimental field of Guangxi Academy of Agricultural Sciences
[0045] Table 1
[0046] Comparison table of sprayed and unsprayed products
[0047]
[0048] Table 2
[0049]
[0050] It can be seen from the per-mu yield data in Table 1 and Table 2 that the rice functional foliar fertilizer treatment has the highest yield per mu, which is 6% and 5% higher than other foliar fertilizer 1 and foliar fertilizer 2 on the market, respectively.
