Capsule type potato seed

Abstract

The invention discloses a capsule type potato seed, which is characterized by comprising a capsule body, wherein potato columnar tubers with bud eyes are coated in the capsule body. Potato seed with bud eyes are made into' artificial seeds' for production and planting, in the production process, the planting time is not limited, industrial production can be preformed, so that the production efficiency is improved, and the transportation cost can be reduced.

Description

technical field [0001] The invention relates to a new technical field of potato vegetative propagation, in particular to a tuber capsule for vegetative potato propagation with compact space, high manufacturing efficiency, low labor cost and reduced transportation cost. Background technique [0002] In terms of production, most tetraploid potatoes are self-incompatible. Even if self-compatible potato seeds are used for sexual reproduction, undesirable phenomena such as trait segregation and self-recession often occur. Therefore, conventional potato propagation methods are tuber vegetative propagation, but many problems are often encountered in the tuber propagation process: 1. In the process of cutting potatoes in the field, the operation is complicated and there is no unified division method, which is relatively random, resulting in There are large differences between different cuts with bud eyes, which may eventually lead to inconsistent emergence time of potatoes, which is...

Problems solved by technology

[0002] In terms of production, most tetraploid potatoes are self-incompatible. Even if self-compatible potato seeds are used for sexual reproduction, adverse phenomena such as trait segregation and self-recession often occur

Therefore, conventional potato propagation methods are tuber vegetative propagation, but many problems are often encountered in the tuber propagation process: 1. In the process of cutting potatoes in the field, the operation is complicated and there is no unified division method, which is relatively random, resulting in There are large differences between different cuts with bud eyes, which may eventually lead to inconsistent emergence time of potatoes, which is not conducive to water, fertilizer and field management; 2. Due to the special physiological characteristics of bud eyes on potato tubers, terminal buds generally emerge faster and have a higher emergence potential. Higher, the lateral buds are slower than the emergence, and the emergence potential is not as good as the terminal buds

If the pieces are cut together, the terminal buds and side buds are randomly piled up, and it is impossible to distinguish the top buds with different parts of the buds. Later, it is easy to cause uneven emergence and different sizes of seedlings in the same plot by machine sowing in the later stage. And field management increases the difficulty; 3. The traditional method of cutting and planting seed potatoes limits the improvement of work efficiency. When working, workers need to judge the total number of cut potatoes and the way of cutting and cutting according to the size and shape of the potatoes. , which invisibly increases the operation time for the cutting work, which is also an unavoidable problem in manual operation; 4. The traditional potato cutting operation requires certain experience and skills, and requires a certain period of training for practitioners, as well as proficiency. The per capita wages of the workers are higher than that of ordinary workers, which increases the labor cost of potato block seed production; 5. The traditional original seed potato blocks generally need to be transported to the planting site and then cut into pieces, but the volume and weight of a single potato block Larger, the transportation cost per unit weight and volume is higher. The national potato seed production bases are generally in Inner Mongolia, Gansu, Yunnan and Guizhou, etc., which are far away from some domestic planting places, and the long-distance transportation costs are extremely high. Increased the planting cost of potato; 6, the traditional potato tuber slicing sowing, the wound surface of often cutting is bigger, and larger wound surface causes bigger difficulty in the process of pretreatment (disinfection, drying, etc.) before sowing, and the wound surface is relatively large. Large, also poses a risk of tuber rot after planting
