Embodiment 1

[0011] Embodiment 1: the ratio of each component is (parts by weight) in the low-concentration special-purpose fertilizer:

[0012] Potassium dihydrogen phosphate 55.16 parts, ammonium molybdate tetrahydrate 23.72 parts, ascorbic acid 10.26 parts, zinc sulfate heptahydrate 15.78 parts, copper sulfate pentahydrate 7.34 parts, ferrous sulfate heptahydrate 20.07 parts, anhydrous boric acid 28.12 parts, humic acid 19.15 parts, 10.05 parts of calcium nitrate, 2.35 parts of sodium selenite.

Embodiment 2

[0013] Embodiment 2: the ratio of each component is (parts by weight) in the high-concentration special-purpose fertilizer:

[0014] Potassium dihydrogen phosphate 78.25 parts, ammonium molybdate tetrahydrate 29.63 parts, ascorbic acid 10.26 parts, zinc sulfate heptahydrate 15.78 parts, copper sulfate pentahydrate 7.34 parts, ferrous sulfate heptahydrate 20.07 parts, anhydrous boric acid 28.12 parts, humic acid 19.15 parts, 10.05 parts of calcium nitrate, 2.35 parts of sodium selenite.

[0015] The method of using the above-mentioned special fertilizer is as follows: firstly, according to the soil fertility level, select the special fertilizer with different concentrations; then, the spraying amount per mu is 192-221g, mixed with 50kg of water, and it is advisable to spray after dissolving and shaking well. And the special fertilizer spraying starts from the pasture plant height of 15cm, spraying once every 8 days, and spraying three times in a row; spraying after 4 pm is the ...

Abstract

The invention relates to a special fertilizer for pasture rich of selenium, which basically comprises the following components: monopotassium phosphate, ammonium heptamolybdate tetrahydrate, ascorbic acid, heptahydrate zinc sulphate, chalcanthite, ferrous sulfate heptahydrate, anhydrous boric acid, humic acid, calcium nitrate and sodium selenite. A method for producing the special fertilizer comprises the following steps: respectively crushing the components into powder and then uniformly the powder according to a certain proportion. The special fertilizer for pasture rich of selenium can increase the yield of pasture by 15 percent-30 percent, improve the selenium content in a body by 5 times-30 times, improve the contents of mineral elements including calcium, phosphorus, zinc, ferrum, copper, molybdenum, and the like by more than 15 percent and improve the crude protein content by more than 10 percent; and the produced pasture rich of selenium is safe to utilize and has complete nutrition and high additional value.

Description

Technical field: [0001] The invention relates to a special selenium-enriched fertilizer, in particular to a special selenium-enriched fertilizer for grass. Background technique: [0002] Selenium is an essential micronutrient element for animal life and is known as the "kindling of life". Selenium has the functions of scavenging free radicals, anti-oxidation, protecting biofilm, improving animal reproduction ability and enhancing body immunity. According to reports, there are more than 40 countries and regions in the world that are deficient in selenium, and 2 / 3 of the areas in my country are selenium deficient areas, forming a soil "selenium deficient belt" from northeast to southwest; resulting in low selenium content in pastures in these areas, Thereby causing various animal diseases such as white muscle disease, mulberry heart disease, gastric ulcer and myorubinuria. Usually, people use selenium fertilizer to increase the selenium content in crops, and then meet the ani...
