Embodiment 1

[0061] Experimental group: a storage method for corn seeds, the steps are as follows:

[0062] Step 1: Preferential labeling of seeds, select mature corn seeds with good plant growth, lodging resistance, and full germplasm particles for harvesting, and mark the batch;

[0063] Step 2: Drying and removing impurities, turning the harvested preferred seeds evenly in the sun, and sorting and removing the soil, weeds, and particles that are not full in the seeds;

[0064] Step 3: Detect the germination rate, detect the germination rate of different batches of corn seeds, and eliminate the seeds of unqualified batches of germination rate;

[0065] Step 4: Sterilization, the dried corn seeds are subjected to ozone sterilization;

[0066] Step 5: Drying, freezing high-quality corn seeds at -20°C for 10 minutes for low-temperature drying, and detecting that the water content is 12%;

[0067] Step 6: Coating the seeds, coating the seeds with a seed coating agent formulated with the fu...

Embodiment 2

[0082] A storage method for corn seeds, the steps are as follows:

[0083] test group:

[0084] Step 1: Preferential labeling of seeds, select mature corn seeds with good plant growth, lodging resistance, and full germplasm particles for harvesting, and mark the batch;

[0085] Step 2: drying and removing impurities, evenly drying the harvested optimal seeds (ears) after removing the bracts;

[0086] Step 3: Sterilization, the dried corn seeds are sterilized by ultraviolet light;

[0087] Step 4: Drying, freezing high-quality corn seeds at -20°C for 12 minutes for low-temperature drying, and detecting that the water content is 16%;

[0088] Step 5: seed coating, using the seed coating agent prepared by the fungicide thiram and the insecticide imidacloprid 1:1 to coat the seeds;

[0089] Step 6: storage, the coated seeds were refrigerated at 4°C.

[0090] Adopt the method of this implementation to carry out the storage (ear storage) of corn seeds, the ear storage is suitabl...

Abstract

The invention discloses a storing method of corn seeds. The storing method comprises the following steps: 1, seed optimal selection and marking are conducted, specifically, the mature core seeds withgood plant growth vigour, lodging-resistant germplasm and full grains are selected, harvested and marked with the batch; 2, sun-curing and impurity removing are conducted, specifically, the harvestedoptimally-selected seeds are evenly tedded, and soil, weeds and not full grains in the seeds are picked and removed; 3, the germination rate is detected; 4, sterilization is conducted; 5, drying is conducted; 6, seed coating is conducted; and 7, storing is conducted, specifically, the seeds are stored at the low temperature. According to the storing method of the corn seeds, the problems that as for an existing storing method of the corn seeds, the insect attack and mildew generating rates are high, and the germination rate is low are solved.

Description

technical field [0001] The invention relates to the technical field of agricultural plant breeding, in particular to a method for storing corn seeds. Background technique [0002] Corn is one of the three major food crops in my country, which occupies an important position in agricultural production and is widely distributed in my country. With the large-scale use of hybrid corn seeds, corn seeds produced by some seed companies often have reduced seed vigor and seed value due to improper storage and storage, which has affected the income of seed companies and agricultural production. [0003] Therefore, according to the characteristics of corn seed storage, adopting a reasonable storage method plays an important role in maintaining seed vitality, promoting seed companies to increase operating income, and ensuring agricultural production safety. [0004] Seed storage refers to the preservation process of seeds after harvesting and before sowing. During the storage process, ...
