Problems solved by technology

[0006] As South American quinoa is native to the Andean plateau, it has strict requirements on temperature, precipitation, soil and other conditions, so domestic introduction and cultivation are greatly restricted
South American quinoa is a crop that is not suitable for repeated cropping. For South American quinoa crops harvested from seeds, continuous planting in the second year will cause low yield problems; however, there are few restrictions on the cultivation of South American quinoa seedlings, and the climatic conditions in almost all parts of the country are suitable for planting

Embodiment 1

[0027] A method for cultivating quinoa seedlings in South America, comprising the following steps:

[0028] (1) Variety selection: There are no strict requirements on the species for the cultivation of South American quinoa seedlings, but from the perspective of economic benefits, varieties with strong growth and many branches and leaves should be selected; that is, South American quinoa seeds with strong growth and many branches and leaves should be selected;

[0029] (2) Plot selection

[0030] The plot should choose fertile soil with good soil structure, loose soil, strong fertilizer and water retention, and high organic matter content. Low-lying areas with poor drainage cannot be used;

[0031] (3) Build a greenhouse

[0032] In order to ensure planting and production throughout the year, facility sheds should be built on the planting plots; the temperature inside the shed should be kept above 15°C at night in winter, and 20-25°C during the day; during the high temperatur...

Embodiment 2

[0050] A method for cultivating quinoa seedlings in South America, comprising the following steps:

[0051] (1) Variety selection: choose South American quinoa seeds with strong growth and many branches and leaves purchased in the market;

[0052] (2) Plot selection: choose flat land with good soil structure, loose soil quality, strong fertilizer and water retention, good drainage, soil pH 5.5-8.5, organic matter content 15-70 g / kg, available nitrogen content 100-200 mg / kg kg, available potassium content 100-1600 mg / kg;

[0053] (3) Build a greenhouse: build a greenhouse on the planting plot; keep the temperature in the shed above 15°C at night in winter and 20-25°C during the day; during the high temperature season in summer, open the side of the shed to maintain ventilation;

[0054] (4) Fertilization for soil preparation: plow the land before planting, and apply 30-45 t / hm of decomposed organic fertilizer 2 , choose diammonium phosphate as the base fertilizer, and the app...

Embodiment 3

[0062] A method for cultivating quinoa seedlings in South America, comprising the following steps:

[0063] (1) Variety selection: choose quinoa seeds with strong growth and many branches and leaves;

[0064] (2) Plot selection: choose flat land with good soil structure, loose soil quality, strong fertilizer and water retention, good drainage, soil pH 5.5, organic matter content 15g / kg, available nitrogen content 100mg / kg, and available potassium content 100mg / kg ;

[0065] (3) Build a greenhouse: build a greenhouse on the planting plot; keep the temperature in the shed above 15°C at night in winter, and keep the temperature at 20°C during the day; during the high temperature season in summer, the sides of the shed are uncovered to maintain ventilation;

[0066] (4) Fertilization for soil preparation: plow the land before planting, and apply 30 t / hm of decomposed organic fertilizer 2 , choose diammonium phosphate as the base fertilizer, and the application rate is 300 kg / hm ...

Abstract

The invention provides a Chenopodium quinoa willd cultivation method. The Chenopodium quinoa willd cultivation method comprises the steps of 1, choosing a variety, wherein Chenopodium quinoa willd seeds which have robust growth vigor and many branches and leaves are chosen; 2, choosing a land block, wherein flat land which is good in soil structure, loose in soil quality and high in fertilizer retention and water retention is chosen, drainage is good, pH of soil is at 5.5-5.8, the organic matter content is 15-70 g/kg, the available nitrogen content is 100-200 mg/kg, and the available potassium content is 100-1600 mg/kg; 3, erecting a warehouse, wherein the warehouse is erected in the planting land block, the temperature in the warehouse at night in winter is kept at 15 DEG C or above, and the temperature in the day is kept at 20-25 DEG C; in a hot season in summer, the side face of the warehouse is uncovered, and ventilation is kept.

Description

[0001] Technical field: [0002] The invention relates to a method for cultivating South American quinoa seedlings. [0003] Background technique: [0004] South American quinoa (Chenopodium quinoa willd), also known as quinoa, quinoa quinoa, quinoa, etc., is an annual self-pollinating dicotyledonous plant of the genus Chenopodium. It has a planting history of more than 5000-7000 years. South American quinoa seeds have high protein content and a balanced composition of essential amino acids, as well as other nutrients such as unsaturated fatty acids are also very rich. NASA lists quinoa as one of the ideal foods for astronauts on long-duration space missions. The Food and Agriculture Organization of the United Nations (FAO) recommends quinoa as a "whole nutritional food" suitable for human consumption, and proposes to designate 2013 as the "International Year of Quinoa", aiming to draw the world's attention to the biodiversity and nutritional value of quinoa. [0005] Quinoa...
