Quinoa is the traditional staple food of the Indians. It was domesticated almost at the same time as rice and has a history of more than 6,000 years of cultivation and consumption. Quinoa has a fairly comprehensive nutritional content, and its taste and flavor are easily accepted by people.

[0003] However, quinoa is a shallow-rooted crop with fragile stems that are prone to lodging and stem breakage. When planted in low-altitude areas, it is prone to lodging, which reduces quinoa yields. Summary of the invention

[0007] Preferably, the silicon nutrient is a mixture of bioactive organic silicon and nano-active silicon, or a mixture of sodium silicate and potassium silicate.

[0008] Preferably, the surfactant is a mixture of two of Tween 20, Tween 60 and Tween 80, or a mixture of Tween 20, Tween 60 and Tween 80.

[0009] Preferably, the chlormequat chloride, uniconazole and trinexapac-ethyl are all growth-retarding active substances, and trinexapac-ethyl and uniconazole can be replaced by mepiquat chloride and prohexadione-calcium in the same proportion.

[0010] Preferably, the sodium indolebutyrate is an auxin active substance, and the sodium indolebutyrate can be replaced by sodium indoleacetate and sodium naphthylacetate or one of them.

[0011] A method for preparing a seed treatment agent for improving the lodging resistance and yield of quinoa comprises the following steps: weighing a required amount of uniconazole of corresponding content, pouring the uniconazole into a container, adding water, stirring and grinding, dissolving the uniconazole for a period of time, adding gamma-aminobutyric acid, sodium indolebutyrate, chlormequat chloride, uniconazole, trinexapac-ethyl and silicon nutrient solution respectively dissolved in water, finally adding anhydrous ethanol to dissolve an abscisic acid solution, adding a surfactant, continuing stirring for a period of time, and fully mixing to obtain the seed treatment agent.

[0012] Preferably, the prepared seed treatment agent can be dried to prepare a powdered seed treatment agent for seed dressing.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The seed treatment agent prepared by the present invention can effectively control the height of quinoa plants, increase the thickness of the rhizomes of quinoa plants, make the quinoa plants more upright, avoid lodging, and at the same time reduce the area occupied by a single quinoa plant, increase the density of quinoa plants planted in the same square, and thus improve the yield.
