Embodiment 1

[0026] Harvest mature corn ears on September 30th of the first year, peel them and spread them in the sun after cleaning up impurities greater than 5cm, fill up ditches with a depth or width greater than 5cm, set up fences around them, disinfect with 10kg of quicklime per mu and lay a long layer. 50m wide and 6-10m black drying nets are used for drying. The average daily sunlight is 9 hours, the daily average temperature is 10°C, the relative humidity is 3%, the groundwater level is 10m, and the surface moisture content is 3%. At the same time, the slope of the drying site is less than 50 degrees and the surrounding area is open and well ventilated. The corn ears are piled up in 2 layers for drying.

[0027] During the drying process of corn ears, an isolation area with a width of 5m is set up between the adjacent drying areas of different varieties of corn. Turn over once every 3 days, and after 15 days of drying, the moisture content of corn kernels in all corn ears is less...

Embodiment 2

[0030] On September 15th of the second year, the mature corn ears were harvested and peeled, and spread out in the sun after cleaning up the impurities larger than 5cm, filling the ditches with a depth or width larger than 5cm, setting up fences around them, disinfecting with 10kg quicklime per mu, and laying a long layer. 50m wide and 6-10m black drying net drying site, the average daily sunlight of the drying site is more than 9 hours, the daily average temperature is 10.5°C, the relative humidity is 2.7%, the groundwater level is 11m, and the surface moisture content is 2.8%. At the same time, the slope of the drying site is less than 50 degrees and the surrounding area is open and well ventilated. The ears of corn are stacked in 4 layers for drying.

[0031]During the drying process of corn ears, a 6m-wide isolation zone is set up between the adjacent drying areas of different varieties of corn. Tumbling once every 5 days, after 17 days of drying, the moisture content of ...

Embodiment 3

[0034] On September 20th of the third year, mature corn ears are harvested and peeled, and placed in a place where impurities greater than 5cm are cleaned, ditches with a depth or width greater than 5cm are filled, fences are set around, 10kg of quicklime is used for disinfection per mu, and a layer of 50m long is laid. A drying site for black drying nets with a width of 6-10m. The average daily sunlight of the drying site is more than 9 hours, the average daily temperature is 11°C, the relative humidity is 2.5%, the groundwater level is 12m, and the surface moisture content is 1.9%. At the same time, the slope of the drying site is less than 50 degrees and the surrounding area is open and well ventilated. The corn ears are piled up in 6 layers for drying.

[0035] During the drying process of corn ears, a 5m-wide isolation zone and a 1m working path shall be set up between adjacent drying areas of different varieties of corn. Turn over once every 8 days, and after 20 days of...

Abstract

The invention relates to the technical field of agriculture and provides an air-drying method for corn seed production. The air-drying method is characterized by comprising the step of placing corn ears in an air-drying site with the daily average light of more than or equal to 9 h, the daily average temperature of more than or equal to 10 DEG C and the relative humidity smaller than or equal to 50% and conducting air-drying for 15-20 days, wherein the ground surface moisture content of the air-drying site is smaller than or equal to 3%, the underground water level is more than or equal to 10 m, and the average wind speed is smaller than or equal to 3 m / s. By adoption of the air-drying method, the corn ears can be air-dried more fully, and moldy and invalid corn ears are less. The invention also provides a corn seed production method, which comprises the air-drying method for corn seed production and comprises the steps of sequentially performing threshing and drying treatment on the air-dried corn ears. Corn seeds produced by the corn seed production method is high in qualification rate and germination rate.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a drying method for corn seed production and a corn seed production method. Background technique [0002] At present, the existing corn seed production generally adopts the traditional drying method for drying. Although this method has the characteristics of simple operation and large-scale drying, but due to the unreasonable drying environment and various operation methods during the drying process, more mildew occurs during the drying process. germinated corn seeds, and the germination rate of the finally obtained corn seeds is not high. Contents of the invention [0003] The invention provides a drying method for corn seed production, aiming at improving the problem that in the existing drying process of corn seed production, there are many germinated and moldy seeds due to insufficient drying and the quality of the finally obtained seeds is average. [0004] The inve...
