Abstract

The invention discloses a pregermination method used for storage of seed pregermination. The pregermination method comprises following steps: A, seed selection; B, seed soaking and pregermination; C, storage, wherein the ground in rooms facing the sun is covered with plastic film and plastic window screen cloth successively for ventilation, seeds processed via seed soaking and pregermination are piled on the ground with a pile height to be controlled to be 20 to 34cm, the seeds are covered with plastic film so as to maintain the seeds to be wet and reduce water evaporation; D, pregermination and management in storage, wherein the seeds are collected after 2 to 3 months of storage, seed soaking pregermination and storage (without seed soaking) are carried out via the step disclosed above, and seed dressing using 80 to 120PPM of a green plant growth regulator solution is carried out every 2 to 3 months so as to prevent seed drying; E, selection of germinated seeds, wherein the seeds are stored to the December of a next year, gradual germination is realized, no medicine mixing pregermination is carried out until the end of March of a third year, and germinated seeds are selected batch by batch and stage by stage; and F, storage, seed pregermination, and seed selection are carried out continuously.

Description

The germination accelerating method of a kind of storage for seed vernalization

Technical field

The present invention relates to a kind of germination accelerating method, in particular to the germination accelerating method of a kind of storage for seed vernalization, belong to Stratification technique field.

Background technology

Paddy rice is the important food crop of China, and its sown area accounts for the 1/3 of food crop sown area, and paddy ultimate production accounts for about the 45% of total grain output. In China, " locust south, north snout moth's larva " is historic two major pests, and from China's rice cropping system degree of drilling and snout moth's larva history generation situation, rice cropping system is by changing merely complexity into, then yellow rice borer population rises, and striped rice borer population declines. Otherwise, rice cropping system mountain complexity turns into merely, then yellow rice borer population is in and withers and falls, the striped rice borer population criminal of trend fox thereupon. With catching out of stone profitable agriculture, crop mix adjusts further, pesticide species structural modification, and snout moth's larva, to the resistance in various degree such as disosultap, Cupric sulfate, adds that winter temperature is higher, and snout moth's larva amount continues to go up. On market, the medicament of existing water prevention rice borer is mostly neires toxin and organophosphorus. Cupric sulfate wherein uses oneself to produce stronger resistance through for many years, and anti-effect is not ideal enough. In addition on using, there is significant limitation, alone organophosphorus can water prevention rice borer, but consumption is big, and people and animals, environment are all had detrimentally affect��

Summary of the invention

The present invention proposes the germination accelerating method of a kind of storage for seed vernalization, its method is simple, easy to operate, percentage of germination height.

The technical scheme that the present invention solves its technical problem adopts following step to realize.

A, initial point selection: choosing ripe, full pure seed then, seed superiority is more than 80%;

B, presoaking and germinating: sterilized by seed-soaking with 0.25-0.35% potassium permanganate solution and clean with clear water for 3-5 minute, with green plant growth regulator solution seed soaking 20-30 hour of 80-12OPPM, pull out for subsequent use;

C, storage: Chaoyang to flooring on pad plastics film and Plastic screen cloth successively, in order to ventilation, the seed through presoaking and germinating is stacked on it, height 20-34 centimetre, at seed upper cover plastics film, to keep seed moist, reduces moisture evaporation;

D, vernalization between storage period and management: seed is taken out by storage for 2-3 month, again with aforesaid method presoaking and germinating and storage, hereafter within every 2-3 month, (no longer soaking seed) is dressed seed once with the green plant growth regulator solution of 80-120PPM, in case seed drying;

E, pick chitting piece: by this storage of seeds in December, the 2nd, can progressively germinate, until in by the end of March, the 3rd, during this period, do not need to mix medicine vernalization, chitting piece will be picked by stages and in groups;

F, continuing storage, vernalization and pick kind: from April, the 3rd, by remaining seed again with aforesaid method storing and germination accelerating, in December, the 3rd, seed starts to germinate again kind, until in by the end of March, the 4th, still pick chitting piece by stages and in groups by aforementioned method.

The useful effect of the present invention: the germination accelerating method of a kind of storage for seed vernalization that the present invention proposes, its method is simple, easy to operate, percentage of germination height.

Embodiment

Below in conjunction with specific examples, the invention will be further described.

For a germination accelerating method for the storage of seed vernalization, its method adopts following step to realize.

A, initial point selection: choosing ripe, full pure seed then, seed superiority is more than 80%;

B, presoaking and germinating: sterilized by seed-soaking with 0.25-0.35% potassium permanganate solution and clean with clear water for 3-5 minute, with green plant growth regulator solution seed soaking 20-30 hour of 80-12OPPM, pull out for subsequent use;

C, storage: Chaoyang to flooring on pad plastics film and Plastic screen cloth successively, in order to ventilation, the seed through presoaking and germinating is stacked on it, height 20-34 centimetre, at seed upper cover plastics film, to keep seed moist, reduces moisture evaporation;

D, vernalization between storage period and management: seed is taken out by storage for 2-3 month, again with aforesaid method presoaking and germinating and storage, hereafter within every 2-3 month, (no longer soaking seed) is dressed seed once with the green plant growth regulator solution of 80-120PPM, in case seed drying;

E, pick chitting piece: by this storage of seeds in December, the 2nd, can progressively germinate, until in by the end of March, the 3rd, during this period, do not need to mix medicine vernalization, chitting piece will be picked by stages and in groups;
