Filled type potato seed, sowing system, and sowing method

Abstract

The invention discloses a filled type potato seed, a sowing system, and a sowing method. The potato seed comprises a wrapping member, which wraps a column shaped potato tuber with bud eyes. The potatoautomatic sowing system is characterized by comprising the potato seed described by the claim one or two, a potato seed integrating unit, and an automatic seeder. The potato seed integrating unit comprises a shell for storing and fixing a plurality of potato seeds. The automatic seeder comprises a potato seed integrating unit bearing platform, a guiding rail system, an automatic potato seed recognition position control system, and a hole sowing system. The provided sowing system and sowing method have the advantages that the space is integrated, the manufacturing efficiency is high, the laborcost is low, the transportation cost is reduced, large-scale standardization and industrial production can be realized, and the happening rate of miss-seeding and seedling deficiency is greatly reduced.

Description

technical field [0001] The present invention relates to a new type of potato vegetative propagation technology and its sowing system and sowing method, specifically a kind of space-intensive, high production efficiency, low labor cost, reduced transportation cost, large-area standardized and industrialized production, The filling type potato seed and its sowing system and sowing method greatly reduce the probability of missed sowing and lack of seedlings. 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, the conventional potato propagation method is tuber vegetative propagation, but tuber propagation and sowing process often encounter many problems: 1.

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, the conventional potato propagation method is tuber vegetative propagation, but tuber propagation and sowing process often encounter many problems: 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. As a result, 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 the tubers, terminal buds generally emerge faster and the emergence potential Higher, the lateral buds emerge slower than the terminal buds, and the emergence potential is not as good as that of 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 operating 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. 7. Traditional potato seeding systems are all spoon-type or needle-type potato seed delivery methods. The spoon-type seeding system is likely to cause missed seeding, and there are strict restrictions on the shape of potato pieces. Requirements; the needle seeding system will cause damage to the potato blocks during the sowing process, increasing the risk of rotten potatoes, which is not conducive to high-quality and high-yield potatoes; 8. The traditional potato planter has a large seed box, which not only increases the difficulty of making the planter , and also greatly increased fuel power consumption; 9. The traditional sowing system cannot accurately control the sowing depth, resulting in uneven emergence and uneven seedling quality, which brings great difficulties to later field management
