Embodiment 1

[0018] 1. Seedbed preparation: After harvesting the last crop of micro-tubers, treat the soil with dexamethasone one week before laying plastic film on the seedbed; lay plastic film under the seedbed, and punch some small holes in the plastic film to reduce the occurrence of soil-borne diseases. After the plastic film is laid, a 10cm-thick substrate is laid. The substrate is yellow sand in the Tengger Desert. The width of the border is set at 2.3m and leveled;

[0019] 2. Timely transplanting: when the seedlings are 20 days old, the height of the seedlings is 0.7cm, the diameter of the stem is 0.6mm, and the leaves are 5 pieces, put the virus-free seedlings into the seedling hardening room, keep the temperature at 15°C and the humidity at 85%, and after 2 days Open the bottle mouth sealing film and remove the stem tip, and then transplant it after 5 days; plant the detoxified seedlings at a plant spacing of 5 cm and a row spacing of 10 cm after washing, compact the base during ...

Embodiment 2

[0027] 1. Seedbed preparation: After harvesting the previous crop of micro-tubers, treat the soil with dexon or pentachloronitrobenzene one week before laying plastic film on the seedbed; spread plastic film under the seedbed, and punch some small holes in the plastic film to reduce For the occurrence of soil-borne diseases, lay a 15cm-thick substrate after laying a plastic film. The substrate is yellow sand in the Tengger Desert, and the width of the border is set at 2.3m, and it is leveled;

[0028] 2. Timely transplanting: when the seedlings are 25 days old, the height of the seedlings is 0.7cm, the diameter of the stem is 0.8mm, and the leaves are 8 pieces, put the virus-free seedlings into the seedling hardening room, keep the temperature at 20°C and the humidity at 90%, and after 2 days Open the bottle mouth sealing film and remove the stem tips, and then transplant them after 7 days; after the virus-free seedlings are washed, they are planted with a plant spacing of 5 cm...

Embodiment 3

[0036] 1. Seedbed preparation: After harvesting the previous crop of micro-tubers, treat the soil with dexon or pentachloronitrobenzene one week before laying plastic film on the seedbed; spread plastic film under the seedbed, and punch some small holes in the plastic film to reduce For the occurrence of soil-borne diseases, lay a 12cm thick substrate after laying the plastic film. The substrate is yellow sand in the Tengger Desert, and the width of the border is set at 2.3m, and it is leveled;

[0037] 2. Timely transplanting: when the virus-free seedlings are 22 days old, the seedling height is 0.7cm, the stem diameter is 0.7mm, and the leaves are 7 pieces, first put the virus-free seedlings into the seedling hardening room in batches, and keep the temperature at 18°C ​​and the humidity at 88%. After 2 days, open the bottle mouth sealing film and remove the stem tip, and then transplant it after 6 days; after the virus-free seedlings are washed, they are planted with a plant ...

Abstract

The invention discloses a cultivation method for producing miniature potato seeds of virus-free potatoes, relates to a method for producing the miniature potato seeds by combining virus-free potato seedling with the cultivation technology and belongs to the technical field of agriculture. The cultivation method for producing miniature potato seeds of virus-free potatoes is characterized in that yellow sands serve as the culture media, and after the stem tips are removed, specially prepared nutrient solution is adopted. The cultivation method has the advantages that the net income of each mu of adopting yellow sands as the media is equal to the net income of each mu of adopting vermiculite as the media, but the vermiculite is high in production cost, and the yellow sands serving as the media is abundant and can be drawn from local resources, so that the yellow sands can serve as the media to replace the vermiculite for producing the miniature potato seeds of the virus-free potatoes and has wide application prospect. The cultivation method adopts the yellow sands as the cultivation media, the nutrient solution matched with the yellow sands is screened, and the media can be continuously used for four to six batches. After the step tips are removed, nutrition of the plant can be reasonably distributed, and plant rhizome can grow in expansion mode without only enabling plant to grow in height.

Description

technical field [0001] The invention relates to a method for producing miniature seed potatoes by combining virus-free potato seedlings with cultivation techniques, which belongs to the field of agricultural technology, in particular to a cultivation method for producing virus-free potato miniature seeds. Background technique [0002] Potato (scientific name Solanum tuberosum ), a perennial herb, but cultivated as an annual or twice a year; its tubers are edible, and are important food and vegetable crops; they have high nutritional and medicinal values. Generally, fresh potatoes contain 9-20% starch, 1.5-2.3% protein, 0.1-1.1% fat, and 0.6-0.8% crude fiber. Nutrients contained in 100g potatoes: calories 66~113J, calcium 11~60mg, phosphorus 15~68mg, iron 0.4~4.8mg, thiamine 0.03~0.07mg, riboflavin 0.03~0.11mg, niacin 0.4~ 1.1mg; In addition, potato tubers also contain carotene and ascorbic acid that are not found in cereal grains. From a nutritional point of view, it has...
