Description

A kind of red skin onion seed germination accelerating method

Technical field

The present invention relates to vegetable growing field, be specifically related to a kind of red skin onion seed germination accelerating method.

Background technology

A lot of vegetable seeds need vernalization, and the general seed that needs vernalization can be divided into two classes: a class is that fruit vegetables seed sprouting is slow, need to urge kind, as tomato, capsicum, eggplant, cucumber; An other class is that summer temp is high, causes germination rate of vegetable seeds low, thus also need to urge kind, as asparagus lettuce, spinach, onion, garlic.Different vegetables, vernalization mode is separately different.Hang well method, refrigeration, mix micromicrofarad etc.Different vernalization modes, corresponding different vegetable seeds.Before general vernalization,, first through seed selection, sterilization, seed soaking, finally be only vernalization.Conventional germination accelerating method can improve percentage of seedgermination, shortens germination time, alleviates Field diseases, and seedling seedling is neat, seedling strong.But existing germination accelerating method does not all have to improve the nutrient component of vegetables, further improve the quality of vegetables.

Summary of the invention

The invention provides a kind of red skin onion seed germination accelerating method, this germination accelerating method can not only improve percentage of seedgermination, shorten germination time, alleviate Field diseases, seedling seedling is neat, seedling strong, improve output, increased the nutrient composition content of red skin onion simultaneously, further improved the quality of red skin onion.

The technical solution used in the present invention is:

A red skin onion seed germination accelerating method, is characterized in that, comprises the following steps:

(2) seed soaking is put into the container that fills nutrient solution again, container is put into 700w microwave equipment, the firepower microwave treatment with 60% 10 seconds-15 seconds, then stops microwave treatment, takes out to be placed under normal temperature and soaks 3-4 hour;

(3) pull out again with clear water and clean;

(4) above-mentioned soaked seed is bound up with gauze, squeeze and remove part moisture, put into refrigerator at-5～0 ℃ of freezing 2-3 hour, taking-up is put into refrigerating chamber and is thawed, then soaks 3-4 hour in 20-25 ℃ of warm water, pull out, so repeat 2-3 time, then with bundle, and put into presprouting of seeds case, at 20-25 ℃, constant temperature vernalization 12-24 hour, takes out;

(5) seed after constant temperature vernalization is being mixed thoroughly with rare earth, concrete grammar is for after joining 2-3g rare earth and stirring in 40-50g water, add 2.5-3.5kg seed, fully mix thoroughly, then by the weight ratio of seed and fine earth 1:3, mixing thoroughly with fine earth, be seeded into according to a conventional method in seedbed mulching straw, spray again permeablely, generally within 5-6 days, can germinate.

Nutrient liquid described in step (2) is formulated by following component; every liter of nutrient solution comprises the component of following weight: borax 0.3-0.5g, ammonium molybdate 0.2-0.3g, ZnSO47H2O 0.2-0.5g, cupric sulfate pentahydrate 0.2～0.4g, vitamin B1 0.02-0.03g, vitamin c 1-2g, taurine 0.3-0.5g, vitamin D 2-5mg, vitamin E 0.4-0.7g, ferrous gluconate 0.2-0.4g, surplus is water.

In seed soaking agent of the present invention and nutrient liquid, water insoluble active ingredient can adopt water soluble preparation to be added to the water dissolving again.

beneficial effect

Germination accelerating method of the present invention in the time of to seed sterilization, sterilization, has promoted the absorption of nutrition simultaneously.Germination rate can improve 6-12%, and germinating to seedling rate reaches more than 95%.Germination period can shift to an earlier date 1-2 days.
