Description

Potato original seed treatment method

Technical Field

The application belongs to the technical field of crop planting, and particularly relates to a potato breeder seed treatment method.

Background

The perennial sowing area of potatoes in China is large, and various diseases of the potatoes can be caused along with the annual increase of the planting area, the annual planting and other reasons. The main diseases of potato such as late blight, ring rot and soft rot are all caused by potato-borne bacteria, and rhizoctonia and fusarium are also ubiquitous on tubers and in soil. In the potato planting process, if the soil humidity is high, the potatoes are often rotten before emergence of seedlings and do not emerge, or the potatoes are quickly withered after emergence of seedlings, so that the seedlings and ridges in the field are deficient and broken, and the yield is seriously influenced.

At present, the seed potato processing technology is widely applied to production, and has certain effects of improving the emergence rate, promoting the full seedling, preventing and treating plant diseases and insect pests and improving the yield. However, the application of the method has some problems, such as high environmental requirements on the outside, and less obvious effects on emergence rate, yield, quality and the like.

Disclosure of Invention

The technical problem to be solved by the application is to provide a potato stock seed treatment method for improving the emergence rate and disease resistance of the potato stock seed.

The application discloses a potato breeder seed treatment method. The potato breeder seed treatment method comprises the following steps:

cleaning the picked potato original seed potato blocks, and removing impurities and fibrous roots indicated by the potato blocks;

carrying out disinfection and wood-bolting soaking treatment on the cleaned potato blocks;

and spreading and drying the soaked potato blocks in a ventilation, light-tight or scattered light environment until the surfaces of the potato blocks are lignified.

The method for processing the potato breeder seeds comprises the following steps of:

and (3) soaking the mixture by using a sodium hypochlorite solution with the concentration of one thousandth for ten minutes.

Further, according to the method for processing the potato stock seeds, the potato blocks after soaking processing are spread and dried in the environment of ventilation, light-tight or scattered light, wherein the temperature of the spread and dried environment is not more than 23 ℃, the light intensity of the spread and dried is not more than 1 million grams, and the time of the spread and dried is not more than 15 days.

Furthermore, in the above-mentioned method for processing potato stock seeds, the temperature of the spreading and drying environment is 20 ℃, the illumination intensity of the spreading and drying is 1 million grams, and the time of the spreading and drying is 7 to 10 days.

The method for processing the potato breeder seeds further comprises the following steps:

storing the potato blocks in a cold storage at 2-4 ℃ until the surface of the potato blocks is lignified.

The potato stock seed treatment method provided by the invention has the following advantages:

1. the surfaces of the potato blocks are disinfected and are clean and aseptic.

2. The potato block skin is already cork and thickened, which is beneficial to storage and transportation.

3. Some hyperplastic skin holes are formed in the process of the wood embolism, the wood embolism can play a role in closing the skin holes, storage of potato blocks is facilitated, and the potatoes are not easy to rot.

Detailed Description

Embodiments of the present application will be described in detail with reference to the following embodiments and accompanying drawings, so that how to implement the technical means for solving the technical problems and achieving the technical effects of the present application can be fully understood and implemented.

The perennial sowing area of the potatoes in the Shoantong market is stable to more than 300 ten thousand mu, more than 1000 ten thousand grains of the virus-free seed potatoes are needed, the traditional seed potato treatment method is often serious in contamination due to various diseases, particularly soil-borne diseases, the natural elimination rate of the produced virus-free seed potatoes is high, and the bad situation that the supply of the virus-free seed potatoes is insufficient is directly caused.

FIG. 1 is a flow chart of a potato stock processing method according to an embodiment of the present application. Referring to fig. 1, the potato stock processing method of the present application includes the following.

S101, cleaning the picked potato protospecies and removing impurities and fibrous roots indicated by the potato seed.

S102, carrying out disinfection and wood-bolting soaking treatment on the cleaned potato blocks.

S103, spreading and drying the soaked potato blocks in a ventilation, light-blocking or scattered light environment until the surfaces of the potato blocks are lignified.

Specifically, the picked potato blocks are washed gently, some nutrient substances or fibrous roots on the surfaces of the potato blocks are completely washed, namely, the potato blocks are rinsed by clean water, and after the potato blocks are rinsed by clean water, one thousandth of sodium hypochlorite solution can be further used for soaking for ten minutes, wherein the soaking function is as follows: firstly, the surfaces of the potato blocks are disinfected; secondly, the potato block has strong oxidative stimulation, and the stimulation to the faster cork formation of the potato block. And taking out the potato blocks after soaking, and spreading and drying the potato blocks in a closed or scattered light environment generally at the temperature of about 20 ℃, namely in an environment where the sun is not directly irradiated, wherein the illumination intensity of spreading and drying is preferably 1 trilox, the temperature of the spreading and drying environment cannot exceed 23 ℃, and the spreading and drying environment needs ventilation and cannot be a closed environment. Usually, the air-dried product can be stored in a cold storage after being spread for about one week to ten days. The spreading and drying process is also a process of the cassava block wood-bolting, and the water content of the cassava blocks is reduced in the spreading and drying process, so that the cassava blocks are favorable for storage.

In actual operation, the harvested potato original seeds can be cleaned of impurities, put into a mesh bag and rinsed lightly with clear water, or directly put into clear water and put out quickly, then soaked uniformly with a sodium hypochlorite solution, spread and dried in a bamboo ware, and then shielded from light by newspaper to prevent green turning. After 1-2 weeks, after the potato seeds are dried in the air, the potato seeds are stored in a refrigerator at the temperature of 2-4 ℃, and in the refrigerating process, the sensitivity of different varieties to low temperature should be paid attention to, so that sudden and large-scale cooling is avoided, and cold damage is avoided.

The soaking time in clear water or sodium hypochlorite solution is not too long, the bamboo ware is spread and dried in the air after being lifted, the scattering light is better, a layer of newspaper is spread on the bamboo ware to prevent the potato skin from discoloring and cracking, the potato skin can be classified and stored in a warehouse after being spread and dried for several days, and meanwhile, the warehousing measures are started.

In summary, the method for processing the potato breeder seeds provided by the application has the advantages that the skins of the potato breeder seeds are subjected to the pinning treatment, so that the young and tender skins are quickly pinned, the skins are convenient to store and do not rot, the emergence rate and the disease resistance of the potato breeder seeds can be effectively improved, and the yield and the quality of potatoes can be further improved.
