Problems solved by technology

[0003] Seed potato seedling raising is an important part of sweet potato production. The traditional method of seed potato seedling raising has unsatisfactory pest control, serious virus transmission and deposition, which greatly reduces the emergence quality of seed potatoes, and the unreasonable seed arrangement makes seedling emergence irregular. There is no guarantee that the seedlings will be healthy and strong

Embodiment 1

[0031] A method for growing seedlings of sweet potato, the steps are as follows:

[0032] (1) Choose a seedbed, the size of the seedbed is 1.5m in width, 15m in length, artificial heating, sunny leeward, good drainage, fertile soil and no pathogenic bacteria;

[0033] (2) Select seed potatoes, eliminate diseases, insects, freezing, and damage seed potatoes, bleach them with clean water, eliminate floating diseased potatoes, retain seed potatoes of uniform size and neat specifications, and immerse and disinfect the seed potatoes, that is Soak the seeds in a constant temperature warm soup at 50°C for 15 minutes to kill pathogens in the epidermis and cortex. After disinfection, take them out and wait for bed discharge;

[0034] (3) Accelerating the germination operation. Stack the soaked seed potatoes neatly on the seedling bed. The stacking height is 20cm. Keep the seedbed temperature at 37°C. After the seed potatoes begin to germinate, keep the temperature at 32°C, and spray 34 to the...

[0039] A method for growing seedlings of sweet potato, the steps are as follows:

[0040] (1) Choose a seedbed, the size of the seedbed is 1.5m in width, 15m in length, artificial heating, sunny leeward, good drainage, fertile soil and no pathogenic bacteria;

[0041] (2) Select seed potatoes, eliminate diseases, insects, freezing, and damage seed potatoes, bleach them with clean water, eliminate floating diseased potatoes, retain seed potatoes of uniform size and neat specifications, and immerse and disinfect the seed potatoes, that is Soak the seeds in a constant temperature warm soup at 55°C for 8 minutes to kill the pathogens in the epidermis and cortex, and then take it out after disinfection and wait for the bed;

[0042] (3) Accelerating the germination operation. Stack the soaked seed potatoes neatly on the seedbed. The stacking height is 28cm. Keep the seedbed temperature at 34°C. After the seed potatoes begin to germinate, keep the temperature at 28°C, and spray 33 on the s...

[0047] A method for growing seedlings of sweet potato, the steps are as follows:

[0048] (1) Choose a seedbed, the size of the seedbed is 1.5m in width, 15m in length, artificial heating, sunny leeward, good drainage, fertile soil and no pathogenic bacteria;

[0049] (2) Select seed potatoes, eliminate diseases, insects, freezing, and damage seed potatoes, bleach them with clean water, eliminate floating diseased potatoes, retain seed potatoes of uniform size and neat specifications, and immerse and disinfect the seed potatoes, that is Add 50% thiophanate WP to 400 times of water, soak the seeds for 8 minutes, take it out after disinfection and wait for the bed;

[0050] (3) Accelerating the germination operation. Stack the soaked seed potatoes neatly on the seedling bed. The stacking height is 25cm. Keep the seedbed temperature at 35°C. After the seed potatoes begin to germinate, keep the temperature at 30°C, and spray 34 regularly to the seed potatoes every day. Warm water at ℃, ...

Abstract

The invention relates to a seed potato breeding method for sweet potatoes. The seed potato breeding method for the sweet potatoes comprises the following steps: selecting seedbeds, selecting seed potatoes, and soaking and disinfecting the seed potatoes, accelerating germination, arranging potatoes in separated beds, filling gaps of the adjacent seed potatoes with sandy soil and watering bed soil,covering mulch films, and using a four-layer covering method of straw curtains, mulch films, small arch films and large arch films for seed potato seedlings; after the potato seedlings come up out ofthe ground, removing the mulch films, cutting the potato seedlings and separately transplanting in the greenhouse to plant. According to the invention, the seed potatoes are selected and soaked and disinfected to effectively strengthen the pest control, and reduce the spread and deposition of viruses, so as to improve the seedling emergence quality of the seed potatoes, and the sweet potatoes arearranged by using an oblique row method, the head parts and the tail parts of the seed potatoes are pressed by 1 / 5 to 1 / 4, and the seed potatoes are arranged reasonably, therefore, the emergence of the seedlings is uniform to ensure that the seedlings are complete and strong.

Description

Technical field [0001] The invention relates to the technical field of sweet potato seedling raising, in particular to a sweet potato seed potato seedling raising method. Background technique [0002] With the continuous improvement of people's living standards, sweet potato is one of the six health foods selected by the World Health Organization, and its nutritional value is more and more favored by consumers. Due to its anti-cancer effect and rich nutrition, the demand for sweet potato is increasing year by year, and the market prospect is broad. [0003] Seed potato nursery is an important part of sweet potato production. The traditional method of seed potato nursery is not ideal for pest control, virus transmission and deposition are serious, which greatly reduces the quality of seedling emergence, and the unreasonable seeding setting makes the emergence of seedlings irregular. There is no guarantee that Miao is full and strong. Summary of the invention [0004] The present in...
