Abstract
The invention discloses a kind of drying pre-treating methods of rice paddy seed, include the following steps：Rice paddy seed and plant ash are uniformly mixed, mixture A is obtained；Mixture A is fitted into wooden barrel, the layer of plant ash layer on mixture A；Wooden barrel equipped with mixture A is placed in the storeroom being protected from light, places 15-20 hours, screens out plant ash.The rice paddy seed handled by the method for the present invention in the drying process by dry, drying temperature variation is influenced smaller, seed is damaged smaller, improves the germination percentage of seed.
Description
Technical field
The present invention relates to seed drying technical field more particularly to a kind of drying pre-treating methods 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.
Existing rice paddy seed is dried immediately after threshing, and there are two types of existing hybrid rice seeds drying means：The
One is traditional dring yard (or shining pad) natural drying methods, by the thermal energy dry seed of the sun.But the method is influenced by weather,
The high temperature at high noon and strong sunlight can kill seed；Second is mechanical drying method, utilizes the low original of hot-air relative humidity
Reason takes away seed moisture content using the psychrometric difference of seed and hot-air and achievees the purpose that dry, but there are uneven heatings for seed
Problem reduces the germination percentage of seed.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of drying pre-treating method of rice paddy seed,
The rice paddy seed handled using this method can resist sunning temperature change in the drying process or heating temperature is excessively high to seed
Damage, improve the germination percentage of seed.
The present invention provides a kind of drying pre-treating methods of rice paddy seed, include the following steps：
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, the layer of plant ash layer on mixture A；
It is protected from light, in shady and cool storeroom Step 3: the wooden barrel that mixture A is housed obtained in step 2 is placed on, places 15-20
Hour, screen out plant ash.
Preferably, the weight ratio of rice paddy seed and plant ash is 8-10 in step 1：1.
Preferably, in step 2, mixture A is fitted into wooden barrel, so that the depth of mixture A is 40-50 lis in wooden barrel
Rice.
Preferably, in step 2 plant ash layer with a thickness of 0.4-0.7 centimetres.
Preferably, the temperature of storeroom is 23-26 DEG C in step 3, humidity 30%-40%.
Preferably, rice paddy seed is 10-15 days after the maturation of rice paddy seed field, when seed moisture content is 20%-24% in step 1,
Harvesting threshing obtains.
The present invention will gather in, the rice paddy seed after threshing is embedded in plant ash, after placing 15-20 hours, then be done
It is dry, rice paddy seed by the processing in the drying process by dry, drying temperature variation is influenced smaller, heating temperature is excessively high right
The damage of 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, percentage of seedgermination can reach 94%-98%, be much higher than state-set standard（85%）.
