Problems solved by technology

Leaf sheaths with transverse veins; ligule membranous, about 0.2m long, blade flat and broad, linear-lanceolate, base rounded and ear-shaped, glabrous or pilose, midrib stout, margin slightly scabrous, about 1- 1.5 meters, the caryopsis is spherical or oblate, and the glumes and lemmas are exposed after maturity. Its size varies with the growth conditions. It is cultivated in various parts of my country and is widely planted in tropical and temperate regions of the world. It is an important grain. It has a sweet taste and can be used for various dishes, such as corn roasting. At the same time, alfalfa is also a good feed. Cattle, horses, sheep, pigs, and chickens all like to eat it, and it grows fast. Corn planting is simple, but the requirements for corn seeds are relatively high. , the seeds are unqualified, which will directly lead to the reduction of corn yield and excessive diseases

Embodiment 1

[0022] 1) Collect or purchase corn seeds for sorting, preferably corn seeds with full grains and no disease, and remove internal impurities;

[0023] 2) Preliminarily pre-cooling the sorted corn seeds in time. The pre-cooling method is to store all the corn seeds in a cold storage at a temperature of 1° C. for 24 hours.

[0024] 3) Air-dry or directly sun-dry the pre-cooled corn seeds, and sort again to remove useless seeds;

[0025] 4) The precooled corn seeds in step 3 are sprayed and disinfected with 100 mg / L stable chlorine dioxide;

[0026] 5) putting the treated corn seeds in step 4 into batches and sealing them in a high-quality moisture-permeable bag with a wall thickness of 0.025mm;

[0027] 7) Disinfect the warehouse with disinfectant powder and close it for 1 day, then remove the disinfectant powder, and open the ventilation for 3 hours;

[0028] The disinfectant powder is compounded by grinding 20 parts of quicklime, 8 parts of solid potassium permanganate, 10 pa...

Abstract

The invention provides a low-temperature storage method for corn seeds and relates to the technical field of corn planting. The low-temperature storage method comprises steps as follows: seed selection, sterilization and disinfection, spraying of a preservative, bagging, storehouse treatment, temperature and humidity treatment and delivery of the seeds from a storehouse. The low-temperature storage method has the benefits as follows: appropriate conditions for storage of the corn seeds are determined, the proper temperature, humidity and gas composition in the storehouse are guaranteed, the problems about water loss, senescence, yellowing, sprouting and quick rotting of the corn seeds in the storage process are solved, the storage time of the corn seeds is prolonged without damaging the texture, the industrial development of the corn seeds is promoted, the additional value is increased, the yield of the corn seeds is guaranteed, and the income is increased.

Description

technical field [0001] The invention relates to the technical field of corn planting, in particular to a method for low-temperature storage of corn seeds. Background technique [0002] Corn is an annual tall herb with erect stalks, usually unbranched, with aerial strut roots at each node at the base. Leaf sheaths with transverse veins; ligule membranous, about 0.2m long, blade flat and broad, linear-lanceolate, base rounded and ear-shaped, glabrous or pilose, midrib stout, margin slightly scabrous, about 1- 1.5 meters, the caryopsis is spherical or oblate, and the glumes and lemmas are exposed after maturity. Its size varies with the growth conditions. It is cultivated in various parts of my country and is widely planted in tropical and temperate regions of the world. It is an important grain. It has a sweet taste and can be used for various dishes, such as corn roasting. At the same time, alfalfa is also a good feed. Cattle, horses, sheep, pigs, and chickens all like to eat ...
