Embodiment 1

[0016] Embodiment 1: be made up of the raw material component of following parts by weight:

[0017] 50 parts of ammonium sulfate, 20 parts of urea, 10 parts of monoammonium phosphate, 20 parts of potassium chloride, 12 parts of boron, 4 parts of selenium, and 0.2 parts of sodium nitrophenolate. The above-mentioned various materials are pulverized and mixed evenly. This formula is especially suitable for food crops.

[0018] How to use: After the crops have passed the seedling stage, add 40-50 kg of water to dilute at 100 g / mu, and spray 2-3 times on the leaves; the spraying interval is 10-20 days.

Embodiment 2

[0019] Embodiment 2: be made up of the raw material component of following parts by weight:

[0020] 50 parts of ammonium sulfate, 20 parts of monoammonium phosphate, 10 parts of potassium dihydrogen phosphate, 20 parts of potassium chloride, 4 parts of boron, 2 parts of selenium, 0.08 parts of sodium nitrophenolate, and 1.5 parts of paclobutrazol. Crush the various materials and mix them evenly. This formula is especially suitable for oil crops.

[0021] How to use: 7-10 days before the flowering period of crops, dilute with 40-50 kg of water at 100 g / mu, and spray 2-3 times on the leaves; the spraying interval is 15-20 days.

Embodiment 3

[0022] Embodiment 3: be made up of the raw material component of following parts by weight:

[0023] 30 parts of ammonium sulfate, 20 parts of urea, 10 parts of potassium nitrate, 10 parts of monoammonium phosphate, 10 parts of potassium dihydrogen phosphate, 20 parts of potassium chloride, 10 parts of boron, 3 parts of selenium, and 1.9 parts of sodium nitrophenolate. The above-mentioned various materials are pulverized and mixed evenly. This formula is especially suitable for vegetable cultivation.

[0024] How to use: From the seedling stage, after diluting with 40-50 kg of water per mu at 100 g / mu, spray 3-4 times through the leaves; the spraying interval is 10-15 days.

Abstract

The present invention is one kind of multiple-effect selenium-rich agent suitable for being applied to foliage of plant. It consists of ammonium sulfate, urea, ammonium nitrate, ammonium phosphate, potassium biphosphate, potassium chloride, potassium nitrate, boron and selenium and may contain sodium nitrophenolate, paclobutrazol or hesperidinase. As one kind of foliage fertilizer, the present invention is suitable for some crops and is used to increase crop selenium content, increase crop yield, improve crop quality, regulate crop growth, and strength crop resistance.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a fertilizer suitable for use on leaves. technical background [0002] Chinese scientists have measured the selenium content of soil samples from 1094 counties and cities in my country, and the results show that only 1 / 3 of the counties reach the internationally announced normal critical value of 0.1 mg / kg, and the remaining 2 / 3 areas are selenium-deficient areas. Wherein the content ≤ 0.02mg / kg accounts for 29%, is the severe selenium deficiency area. [0003] Selenium is an essential element in life activities. Selenium deficiency is closely related to various human diseases, and it is one of the causes of Keshan disease and Kaschin-Beck disease. Selenium is an integral component of glutathione peroxidase. Glutathione peroxidase participates in the oxidation process of the human body, which can prevent the oxidation of unsaturated acids and prevent aging and tissue hardening caused by...
