Embodiment 1

[0022] A low-temperature storage method for corn seeds, comprising the steps of:

[0023] 1) Seed treatment: Eliminate necrotic or germinated but broken seeds, select healthy seeds to contact with anhydrous light alcohol and catalyst, the catalyst is Fe 2 o 3 -CaO-SiO 2 with B 2 o 3 According to a certain mass ratio, B 2 o 3 The mass ratio is Fe 2 o 3 -CaO-SiO 2 5% of 5%, and then carry out ventilating and disinfecting treatment with clear water spray liquid after treatment; The mass proportion of described anhydrous light alcohol and catalyst is 20:30.

[0024] 2) Ultrasonic seed dressing: select angelica powder, codonopsis powder and cobalt oxalate powder to mix evenly, then stir evenly in a sodium carbonate solution in a water bath at 30°C, and then treat the reaction system in a low-frequency pulsed magnetic field, and at the same time carry out low-voltage electromagnetic treatment. After the treatment is completed, freeze at -28°C for 3 hours, and then filter to...

Abstract

The invention discloses a low-temperature storage method of corn seeds, and belongs to the technical field of seed storage. The low-temperature storage method of the corn seeds is realized through three steps of seed treatment, ultrasonic seed dressing and drying storage. Angelica sinensis powder, codonopsis pilosula powder and cobalt oxalate powder are subjected to pulse electromagnetic treatment, so that the influence of diseases on crop can be effectively reduced, the cold damage resistance of the seeds is improved, the moisture content is reduced, the absorption is accelerated during post-treatment, the seed vigor is improved, and the storage life is prolonged. According to the method, the angelica sinensis powder and the codonopsis pilosula powder are subjected to secondary treatmentto form a shell for protecting the seeds, and the seeds are not hindered to a certain extent, so that the seeds can grow healthily in an adverse environment, and the crop yield is increased. Accordingto the low-temperature storage method, the germination rate of the seeds ranges from 92.4% to 94.1%, the disease occurrence rate is greatly reduced, the yield per mu ranges from 614.7 kg / mu to 616.6kg / mu, the yield is increased by 22.77% to 23.17%, and economic benefits are remarkable.

Description

technical field [0001] The invention belongs to the technical field of seed storage, and in particular relates to a method for low-temperature storage of corn seeds. Background technique [0002] Corn (Zea mays L.) is an annual herbaceous plant of Poaceae. As a high-yield food crop in China, corn is an important source of feed for animal husbandry, aquaculture, aquaculture, etc. One of the indispensable raw materials. Because corn resources are extremely rich, cheap and easy to obtain, they also have many biological activities, such as anti-oxidation, anti-tumor, lowering blood sugar, improving immunity and antibacterial sterilization, etc., which have broad development and application prospects. [0003] Due to differences in seed maturity, increased breakage during threshing, and various factors such as heat damage or freezing damage, the physiological activity of seeds can be increased. Promote the enhancement of respiration, so that the seeds are not easy to store. Wh...
