1. A treatment method for improving herbage seed yield, comprising:
spraying arginine chelated selenium foliar fertilizer during herbage growth period, the herbage growth period being one of blooming period and growing period, wherein preparing the arginine chelated selenium foliar fertilizer comprises:
dissolving arginine in water to obtain dissolved solution; wherein a mass-volume ratio of the arginine: the water is 1 g:15 mL˜20 mL;
adding soluble selenium salt into the dissolved solution to perform a chelation reaction under a pressure to obtain arginine chelated selenium solution; wherein a temperature of the chelation reaction is between 110° C. and 120° C., a time of the chelation reaction is between 30 min and 40 min, and the pressure is between 0.3 MPa and 0.5 MPa;
diluting the arginine chelated selenium solution with water to obtain the arginine chelated selenium foliar fertilizer;
wherein the soluble selenium salt is at least one selected from a group consisting of sodium selenite and sodium selenate; and
wherein a molar ratio of the arginine: the soluble selenium salt is 2˜3:1.
 
5. A treatment method for improving herbage seed yield, comprising:
spraying arginine chelated selenium foliar fertilizer during herbage growth period, wherein preparing the arginine chelated selenium foliar fertilizer comprises:
dissolving arginine in water to obtain dissolved solution; wherein a mass-volume ratio of the arginine: the water is 1 g :15 mL˜20 mL;
dissolving soluble selenium salt in the dissolved solution, and then transferring the dissolved solution to a pressure reactor to perform a chelation reaction under a pressure between 0.3 MPa and 0.5 MPa, and thereby obtaining arginine chelated selenium solution; wherein a molar ratio of the arginine: the soluble selenium salt is 2˜3:1, a temperature of the chelation reaction is between 110° C. and 120° C., and a time of the chelation reaction is between 30 min and 40 min; and
diluting the arginine chelated selenium solution with the water after cooling down until that a content of selenium is 40 ppm, thereby obtaining the arginine chelated selenium foliar fertilizer;
wherein the soluble selenium salt is at least one selected from a group consisting of sodium selenite and sodium selenate.
