Problems solved by technology

At present, soil burial is often used to treat the discarded medium after tissue culture. However, soil burial will destroy the soil structure on the one hand, and the enrichment and culture of microorganisms brought about by it will also have great uncertainty. It is conducive to subsequent development and use. On the other hand, land is limited, and the method of soil burial is not a long-term solution

Embodiment 1

[0036] The cultivation of a kind of potato seedling of embodiment 1

[0037] (1) Cultivation of shoot tip seedlings

[0038] Choose healthy potatoes, treat the terminal buds or side buds together with some petioles and stems in 70% alcohol for 30s, then soak in 10% bleach solution for 5-10min, and then rinse with sterile water two or three times;

[0039] After disinfection, put it under a binocular dissecting microscope of 10-40 times to peel off, press the stem bud with tweezers in one hand, and peel off the young leaves and large leaf primordia with a dissecting needle in the other hand until the round and bright growth points are exposed. Use a scalpel to cut off the small shoot tip with one or two leaf primordia, and quickly inoculate it on the shoot tip seedling medium for cultivation. The cultivation temperature is (25±2)°C, and the light intensity is 1000 lx for the first 4 weeks, and increases after 4 weeks. To 2000-3000lx, 16h of light per day, grow into seedlings a...

Embodiment 2

[0048] Embodiment 2 A kind of method of producing original seed of potato

[0049] (1) Disinfection: Before transplanting, use disinfectant to carry out thorough disinfection and insecticidal treatment on the transplanting seedbed to prevent soil-borne diseases and insect pests;

[0050] (2) Watering: evenly water the vermiculite one day before transplanting, so that the water holding capacity of the vermiculite reaches saturation;

[0051] (3) transplanting: the potato seedling of embodiment 1 gained is planted in the vermiculite of seedbed, makes shoot expose 2-3 leaf, and plant row spacing is 3 * 10cm (280-330 plants / m 2 );

[0052] (4) Pesticide application and film covering: After the seedlings are transplanted, sprinkle water evenly to make the seedlings fully contact with the seedbed; then use 52.5% Yikuaijing WP1800 times liquid to spray for sterilization and protection, and then build a small arch shed and film, and cover the sunshade Netting, moisturizing and heat pr...

Embodiment 3

[0074] Embodiment 3 A kind of organic fertilizer for producing the original seed of potato

[0075] (1) Disinfection: Before transplanting, use a disinfectant to thoroughly disinfect the seedbed and kill insects to prevent the spread of diseases and insect pests in the soil;

[0076] (2) Watering: evenly water the vermiculite one day before transplanting, so that the water holding capacity of the vermiculite reaches saturation;

[0077] (3) transplanting: the potato seedling of embodiment 1 gained is planted in the vermiculite of seedbed, makes shoot expose 2-3 leaf, and plant row spacing is 3 * 10cm (280-330 plants / m 2 );

[0078] (4) Pesticide application and film covering: After the seedlings are transplanted, sprinkle water evenly to make the seedlings fully contact with the seedbed; then use 70% mancozeb WP1000 times liquid to spray for sterilization and protection, then build a small arch shed and cover with film Shade net, moisturizing and heat preservation, to ensure...

Abstract

The invention belongs to the technical field of potato breeding, and particularly relates to a method for manufacturing potato breeder's seeds. The method comprises the steps of disinfecting, watering, transplanting, pesticide applying, laminating, stem pressing, temperature management, water management, spindling control, harvesting and the like. An adopted seedbed matrix adopts solid medium particles for replacing vermiculite, a waste culture medium in the seedling production process is added into adopted organic fertilizer, the seedbed cost is lowered by 15-20%, and the yield of the breeder's seeds can be increased to a certain degree; on one hand, the per unit output breeder's seed production cost is lowered; on the other hand, the purpose of after-treatment of the waste culture mediumis achieved.

Description

Technical field: [0001] The invention belongs to the technical field of potato breeding, and in particular relates to a method for producing original potato seeds. Background technique: [0002] The original potato seed is the preferred potato seed for modern potato planting. It selects high-quality potato seed potatoes, detoxifies the stem tip, and starts tissue culture and rapid propagation after virus detection. After 10-15 days, the tall and strong potato seedlings with a length of 10-15 cm are cut and obtained for colonization. At present, most of the virus-free seedling cuttings are cultivated on a special substrate in the greenhouse to obtain the original seed. Because the virus-free seedlings are planted directly using soil, it is generally difficult to survive or the survival rate is extremely low. Therefore, at present, a composite matrix composed of vermiculite, organic fertilizer and soil is generally used to plant the virus-free seedlings to produce original sp...
