Embodiment 1

[0032] High-moisture wheat seed preservation method:

[0033] (1) Temporary storage of high-moisture wheat seeds through mechanical ventilation;

[0034] Generally, the safe storage moisture of wheat seeds is less than 13%. When purchasing, seed companies first store high-moisture wheat seeds separately according to the variety and moisture content. The moisture range of seeds temporarily stored in the same warehouse varies from 0 to 3%. like figure 1 , figure 2 As shown, the temporary storage method is to set up the ventilation channel 3 in the warehouse 1 for flat storage, and set up multiple parallel horizontal ventilation channels and one longitudinal ventilation channel at the bottom. The distance between roads 3 is less than the height of grain layer 2, and the height of grain layer 2 in the warehouse is controlled below 4 meters. Fan 4 (T4-72 centrifugal fan, fan speed 2900 rpm, wind pressure above 1400pa) is used to blow air to the warehouse. The air duct 3 at the ...

Embodiment 2

[0040] High-moisture rice seed preservation method:

[0041] (1) The step of temporarily storing high-moisture rice seeds through mechanical ventilation;

[0042] Generally, the safe storage moisture of rice seeds is less than 14.5%. When purchasing, seed companies first store high-moisture rice seeds separately and temporarily according to different varieties and moisture. like image 3 , Figure 4 As shown, the temporary storage method adopts a cross-shaped ventilation channel 3 arranged at the bottom of the storage 6, and the outside of the storage is sealed and stacked with plastic cloth 5. The diameter of the storage 6 pile is within 7 meters, the height of the cylinder is below 4 meters, and the upper cone When the height is 3 meters or less, fan 4 (T4-72 centrifugal fan, fan speed 2900 rpm, wind pressure above 1400pa) is used to blow or suck air from the ventilation channel 3 at the bottom of the storage body, requiring grain layer The airflow in 2 is even and consis...

Abstract

The invention discloses a method for conserving high moisture seeds. The method comprises the steps of mechanically ventilating and temporarily storing the high moisture seeds, drying the seeds to a safe storage standard of moisture, and placing the dried seeds to a warehouse and safely storing the seeds. The method solves the conservation problem in the period from harvesting to drying of the high moisture seeds, seed vitality is ensured, and meanwhile effective time is gained for the drying operation. Due to the fact that it is quite important for a seed production enterprise to complete seed purchasing operation in a quality and quantity guaranteed mode, the contradiction that the seeds are harvested in a rushed mode and conserved in a short time is relieved, the method is not influenced by the inadequate drying capacity of the enterprise, the strain capacity and anti-disaster capacity are improved under adverse-weather conditions, and the aims that the more seeds are conserved and good seeds are conserved are achieved.

Description

technical field [0001] The invention relates to the field of seed seed preservation processing, in particular to a method for purchasing high-moisture wheat and rice seed seed preservation. Background technique [0002] The traditional method of seed preservation for wheat and rice seeds is to dry and dry them in a timely manner after harvesting from the field, and then put them into the warehouse for safe storage. Generally, the national standard safe storage moisture for wheat seeds is 13.0%, and the national standard safe storage moisture for rice seeds is 13.0%. 14.5%. Affected by the climate and the drying capacity of seed companies, if the seeds that have not reached the safe storage of water are not handled properly, the quality indicators of the seeds will be difficult to guarantee. Moreover, with the reduction of agricultural labor force and the gradual improvement of the degree of mechanization, it has become an urgent requirement for base farmers to directly sell...
