Embodiment 1

[0030] Carry out floating seedling raising with red quinoa variety as material, comprising the following steps:

[0031] (1) Matrix selection and loading

[0032] Peat, vermiculite and perlite are mixed according to the volume ratio of peat: vermiculite: perlite is 3:1:1 to form a matrix, and the matrix is ​​filled in the holes of the foam tray; the non-toxicization of the entire seedling cultivation process can be realized. The foam tray is 68 cm long, 34 cm wide, and 4.5 cm high. The size of the foam plug tray can be 156 holes, and only 18 trays are needed for seedlings per mu, covering an area of ​​5m 2 .

[0033] (2) Seed selection, seed soaking treatment and sowing

[0034] Select plump, healthy red quinoa seeds (seed skin is red), soak the selected red quinoa seeds with 50% carbendazim wettable powder 250 times solution for 40 minutes, and rinse the red quinoa with clean water Seed 4 to 5 times; then red quinoa seeds are sown into the hole matrix of the foam tray in s...

Embodiment 2

[0047] Embodiment 2 Except that the following measures are different, all the other steps are the same as in Embodiment 1. White quinoa varieties are used as materials for floating seedling cultivation.

[0048] (1) Selection of matrix and loading

[0049] The specification of the foam tray is a 136-hole tray.

[0050] (2) Seed selection, seed soaking treatment and sowing

[0051] The sown quinoa seeds are plump, healthy white quinoa variety seeds (that is, the seed skin is white) without diseases and insect pests.

[0052] (3) Floating nursery management

[0053] 1. Cultivation in clear water is the same as in Example 1.

[0054] ②Nutrient solution cultivation: Because the growth and development of white quinoa plants are slow, three times of nutrient solution cultivation can meet the nutritional needs of the growth and development of white quinoa.

[0055] A, the first nutrient solution is cultivated with embodiment 1.

[0056] B, second nutrient solution cultivation i...

Embodiment 3

[0060] Embodiment 3 except that the quinoa variety used is the seed of the yellow quinoa variety (that is, the seed epidermis is yellow).

[0061] Except, remaining steps are identical with embodiment 1. The survival rate of floating seedlings is 100%, and the survival rate of transplanting seedlings is over 98%.

Abstract

Provided is a floating seedling method of quinoa. The method comprises the steps of matrix selection and preparation, seed soaking processing, floating seedling management and the like; according to the floating seedling management step, seeds are cultivated with clear water till the seeds grow to a fourth leaf stage; then the seeds are cultivated with nutrient solution 2-3 times, wherein each time the seeds are cultivated with the nutrient solution for 7 days; cultivated seedlings can be directed transplanted to a big field. The floating seedling method of quinoa is fast in seedling and propagation and short in seedling period, does not carry pathogenic bacteria, and has no soil-borne diseases, the seedlings have high drought-resistant and low-temperature-resistant capacities, the survival rate of floating seedling reaches 95-100%, root systems of the seedlings are numerous and developed, young leaves are big, the quality of the seedlings is good, a large quantity of seedlings can bedirectly transplanted to the big field only after 20-38 days, and the transplanting survival rate reaches 95% or above.

Description

Technical field: [0001] The invention relates to a method for cultivating strong quinoa seedlings by using a floating seedling raising system, and belongs to the technical field of quinoa breeding and seedling raising. Background technique: [0002] Quinoa (Chenopodium quinoa W.) is an annual herb of Chenopodium quinoa. Native to the Andes in South America, it can be planted at an altitude of 1000-4500 meters. Quinoa is a kind of whole grain with high nutritional value, rich in 14%-22% protein, its protein content is twice that of rice; it contains high calcium, phosphorus, manganese, potassium, zinc, magnesium, iron Selenium and other minerals, its mineral element content is higher than that of ordinary grains, 2 times that of wheat, 5 times that of rice and corn; rich in 0.841-1.7mg / 100g of Ve, Vb, Vc and other vitamins and 20 kinds of amino acids, including 9 kinds of amino acids necessary for human body, especially about 4.6%-6.6% of lysine that is lacking in general g...
