Description
Technical field
The present invention relates to agricultural technology field more particularly to a kind of drying means of rice paddy seed.
Background technique
Rice is widely distributed in China, is the important crop in China, is one of most important cereal crops, as directly food
With the food energy provided for the mankind more than 20%.
Rice is one kind of draft Oryza, and the mode of seminal propagation, the quality of rice paddy seed is the core for influencing Rice Cropping
The heart.Seed needs to be dried before storage, it is therefore an objective to prevent from damaging by worms, anti-mildew and frost damage prevention, seed respiratory intensity can be with
The increase of water content and reinforce, while a large amount of moisture content and heat can be released, easily cause the fever mildew of seed, therefore
Seed just can be carried out packaging, storage and transport after must drying.
The rice varieties planted at present are all hybrid rice, and hybrid rice seeds are because of its particularity, and viability is compared to normal
It is more fragile to advise rice paddy seed, meets extreme climate and condition Chang Yi loses vigor, deterioration occurs, reduce germination percentage.So hybridization water
Rice needs higher better drying condition, therefore the dry work of rice paddy seed is the important link of seed processing.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of drying means of rice paddy seed.
The present invention provides a kind of drying means of rice paddy seed, include the following steps：
S1, the rice paddy seed for gathering in threshing is embedded in plant ash, places 12-20 hours, screens out in the storeroom being protected from light
Plant ash obtains pretreatment seed；
S2, pretreatment seed obtained in S1 is put into dryer, is 17%-18% in 30-34 DEG C of drying to water content, then
It is 13%-14% in 38-42 DEG C of drying to water content, is finally 11%-12% in 33-36 DEG C of drying to water content, stops drying, certainly
So cooling, when seed temperature is reduced to 25-28 DEG C, seed is taken out from dryer.
Preferably, the method embedded in S1 is：
Step 1：Rice paddy seed and plant ash are uniformly mixed, mixture A is obtained；
Step 2：Mixture A obtained in step 1 is fitted into wooden barrel, in layer of plant ash layer above.
Preferably, in the method and step one embedded in S1, the weight ratio of rice paddy seed and plant ash is 8-10：1.
Preferably, in the method and step two embedded in S1, mixture A is fitted into wooden barrel, so that mixture A in wooden barrel
Depth is 40-50 centimetres.
Preferably, in the method and step two embedded in S1, vegetation grieshoch with a thickness of 0.4-0.7 centimetres.
Preferably, the temperature of storeroom is 23-26 DEG C in S1, humidity 30%-40%.
Preferably, rice paddy seed is when seed moisture content is 20%-24%, to gather in 10-15 days after rice paddy seed field is mature in S1
Threshing obtains.
The drying means of rice paddy seed provided by the invention mainly includes pretreatment and stage drying two parts, and the present invention is logical
It crosses pretreatment and stage drying gradually reduces seed moisture content, water content is finally made to reach Storage Requirement, drying temperature is suitable for keeping away
Exempt to inactivate because high temperature drying seed causes seed excessive dehydration, avoids the influence to seed vitality, influence percentage of seedgermination.
Preprocess method is that the rice paddy seed after harvesting, threshing is embedded in plant ash, after placing 15-20 hours, then
Be dried, by pretreated rice paddy seed in the drying process by dry, drying temperature variation is influenced smaller, heating temperature
The excessively high damage to seed is smaller, improves the germination percentage of seed.
Just the respiration of the rice paddy seed of harvesting, threshing and metabolic activity are most strong, most active, and the present invention is not straight
It connects the rice paddy seed of high respiratory intensity directly to dry or be placed in dryer and dehydrate, but be embedded in plant ash,
Be protected from light, shady and cool interior is placed on 15-20 hour, reduces the respiratory intensity of rice paddy seed, the active reduction of enzyme in rice paddy seed,
Metabolism degree decline, rice paddy seed respiration release moisture absorbed by plant ash, the moisture in rice paddy seed also under
Drop, is being dried by pretreated rice paddy seed, improves the resistance that seed changes drying condition, improves seed hair
Bud rate.
The present invention avoids rice paddy seed from by heat-flash, avoiding the prominent of drying temperature suddenly by Discrete control drying temperature
So rise or reduce and seed is caused to damage.8%-11% can be improved using the dry Germination Percentage of Rice of the method for the present invention.
