Problems solved by technology

However, these agents can only be applied to the storage of fresh potatoes, not to the storage of seed potatoes.
Because, if these agents are used for the storage of seed potatoes, the germination rate will be low or the growth will not be normal, even if the exogenous gibberellin is used to break dormancy and accelerate germination, it will not be able to obtain better results

Embodiment 1

[0013] 1. Dry the harvested potato micro-seeds in the air for 4 days until the water content of the potato micro-seeds is 40%; after airing, the gained peanut germplasm is piled up and covered for 2 days;

[0014] 2. Continue to dry for 1 day, under the conditions of ambient humidity ≤ 45% and temperature ≤ 18°C, select seed potatoes of uniform size, soak them in 1mg / l cyanin for 15min, and after the water dries, soak them in 5mg / l triiodine Soak in benzoic acid for 15 minutes, and store at 18°C ​​after the water is dried.

[0015] 3. The cultivation method is: soak the seeds with 5 mg / l naphthalene acetic acid solution for 10 minutes, and then soak the seeds with 5 mg / l paclobutrazol solution for 10 minutes.

Embodiment 2

[0017] One, the miniature seed potato of harvesting is aired in the air for 5 days, to 60% of the water content of the miniature potato seed potato; After airing, the gained peanut germplasm is concentrated and piled up for 3 days;

[0018] 2. Continue to dry for 2 days, under the conditions of ambient humidity ≤ 45% and temperature ≤ 18°C, select seed potatoes of uniform size, soak them in 16mg / l green fresh element for 30min, and after the water is dried, use 8mg / l triiodine Soak in benzoic acid for 30 minutes, and store at 20°C after the water is dried.

[0019] 3. The cultivation method is: soak the seeds with 5 mg / l naphthalene acetic acid solution for 10-30 minutes, then soak the seeds with 5 mg / l paclobutrazol solution for 10-30 minutes, and plant them conventionally.

Embodiment 3

[0021] 1. Dry the harvested potato micro-seeds in the air for 5 days until the water content of the potato micro-seeds reaches 60%; after airing, the gained peanut germplasm is concentrated and piled up for 3 days;

[0022] 2. Continue to dry for 2 days, under the conditions of ambient humidity ≤ 45% and temperature ≤ 18°C, select seed potatoes of uniform size, soak them in 16mg / l green fresh element for 30min, and after the water is dried, use 8mg / l triiodine Soak in benzoic acid for 30 minutes, and store at 20°C after the water is dried;

[0023] 3. The cultivation method is: soak the seeds with 5 mg / l naphthalene acetic acid solution for 30 minutes, then soak the seeds with 5 mg / l paclobutrazol solution for 30 minutes, and plant them conventionally.

Abstract

The invention discloses a storage method for potato mini-tubers, relates to a storage method for seed tubers, and belongs to the field of agricultural storage. The method is characterized by comprising the following steps: drying the harvested potato mini-tubers for 4-5 days until the moisture of the potato mini-tubers is 40-60 percent; stacking the dried peanut germplasm for 2-3 days; continuously drying for 1-2 days, selecting the potato seed tubers with a uniform size under the conditions that the environmental humidity is smaller than or equal to 45 percent and the humidity is smaller than or equal to 18 DEG C; soaking with maleic hydrazide of 1-16 mg / l for 15-30 minutes; after the moisture is dried, soaking with triiodobenzoic acid of 5-8 mg / l for 15-30 minutes; after the moisture is dried, storing under the condition of 18-20 DEG C. The storage method has the beneficial effects that the potato storage period is prolonged, the storage period of the potato is adjusted and controlled, the dormancy can be quickly broken in need of germination, robust seedlings are germinated, and the method is easy to operate and is suitable for wide popularization and application.

Description

technical field [0001] The invention relates to a method for storing seed potatoes, which belongs to the field of agricultural storage, in particular to a method for storing miniature potato seeds. Background technique [0002] Potato micro-seed potatoes are small in size, light in weight, low in starch and other nutrients and energy substances, and their growth is weak, and the emergence rate is low. It is easy to cause water evaporation and loss during storage, which often affects germination and emergence, and even caused by improper storage methods. The reduced vigor of seed potatoes affects the yield of seed propagation. The above problems have become the main obstacles to the development of seed potato production. Therefore, how to choose the best storage method, maintain or improve the vigor of miniature seed potatoes through artificial control of environmental factors such as temperature, and explore its mechanism has become an important topic of research at home and...
