A kind of pepper seed germination accelerating method
Technical field
The present invention relates to field of vegetable, be specifically related to a kind of pepper seed germination accelerating method.
Background technology
A lot of vegetable seeds needs vernalization, and the general seed of vernalization that needs can be divided into two classes: a class is that fruit vegetables seed sprouting is slow, needs to urge kind, as tomato, capsicum, eggplant, cucumber; An other class is that summer temp is high, causes germination rate of vegetable seeds low, so also need to urge kind, as asparagus lettuce, spinach, capsicum, garlic.Different vegetables, respective vernalization mode is 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 to be only vernalization.Conventional germination accelerating method can improve percentage of seedgermination, shortens germination time, alleviates Field diseases, and seedling seedling is neat, Miao Zhuan.But existing germination accelerating method does not all have the nutrient component that can improve vegetables, improve the quality of vegetables further.
Summary of the invention
The invention provides a kind of pepper seed germination accelerating method, this germination accelerating method can not only improve percentage of seedgermination, shortens germination time, and seedbed is without weeds, and after seedling replanting, fast, well developed root system, the yield and quality of capsicum is high in growth.
The technical solution used in the present invention is:
A kind of pepper seed germination accelerating method, is characterized in that, comprise the following steps:
(1) after prior to seeding seed being shone 1-2 days, select the seed of full seed, the seed of select is put in container, in chilly water, soak 5-6 hour; Then drop in seed soaking agent the 10-15 minute that soaks seed, pull out clean, wherein seed soaking agent is formulated by following component, the percentage by weight of each component is: lactofen 30-40ppm, brassin lactones 10-15ppm, gibberellin 1-3ppm, DA-610-15PPm, potassium nitrate 40-50ppm, alga fertilizer 200-300ppm, malic acid 10-15ppm, ferrous sulfate 0.2-0.4%, surplus is water, mixes after each component is dissolved in water respectively, be diluted with water to desired concn, stir and get final product;
(2) be dipped into by the seed soaked again and fill in the container of nutrient solution, container is put into 600w microwave equipment, the firepower microwave treatment with 60% 10 seconds-20 seconds, then stops microwave treatment, pulls out;
(3) clean with clear water again;
(4) above-mentioned soaked seed is bound up with gauze, squeeze and remove portion of water, put into refrigerator at 0-5 DEG C of refrigeration 10-12 hour, take out and put into 25-30 DEG C of warm water immersion 12 hours, pull out, again put into refrigerator and cooled and hide 8-10 hour, take out and be reentered in the warm water of 20-25 DEG C and soak 8-10 hour, then pull out to enclose with gauze and put into presprouting of seeds case, at 20-30 DEG C, constant temperature vernalization 12-24 hour, takes out;
(5) seed after constant temperature vernalization is being mixed thoroughly with rare earth, and concrete grammar, for after being joined by 2-3g rare earth and stirring in 40-50g water, adds 2-3kg seed, fully mix thoroughly, then seed and fine earth are mixed thoroughly by the weight ratio of 1:3, are seeded in seedbed according to a conventional method,, within 3-4 days, germinate.
Nutrient liquid described in step (2) is formulated by following component; often liter of nutrient solution comprises the component of following weight: ferrous sulfate 0.3-0.5g, ammonium molybdate 0.2-0.3g, zinc sulphate 0.01-0.03g, manganese sulphate 0.01-0.03g, cupric sulfate pentahydrate 0.2 ~ 0.4g, vitaminB10 .02-0.03g, vitamin c 1-2g, taurine 0.3-0.5g, calciferol-5mg, vitamin E 0.4-0.7g, ferrous sulfate 2-4g, and 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, improve the germination rate of pepper seed, germination rate can reach 100%, improve the field Anti-temperature difference changing capability of capsicum, brassin lactones is with the addition of in seed soaking agent, promotion growth of seedling, all has obvious facilitation to capsicum root system and plant height and seedbed generates without weeds, adds output and improve Quality of Capsicum.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.
Embodiment
A kind of pepper seed germination accelerating method, comprises the following steps:
(1) after prior to seeding seed being shone 1-2 days, select the seed of full seed, the seed of select is put in container, in chilly water, soak 5-6 hour; Then drop in seed soaking agent the 10-15 minute that soaks seed, pull out clean, wherein seed soaking agent is formulated by following component, the percentage by weight of each component is: lactofen 35ppm, brassin lactones 14ppm, gibberellin 2ppm, DA-613PPm, potassium nitrate 45ppm, alga fertilizer 250ppm, malic acid 13ppm, ferrous sulfate 0.3%, surplus is water, mixes after each component is dissolved in water respectively, be diluted with water to desired concn, stir and get final product;
(2) be dipped into by the seed soaked again and fill in the container of nutrient solution, container is put into 600w microwave equipment, the firepower microwave treatment with 60% 10 seconds-20 seconds, then stops microwave treatment, pulls out;
(3) clean with clear water again;
(4) above-mentioned soaked seed is bound up with gauze, squeeze and remove portion of water, put into refrigerator at 0-5 DEG C of refrigeration 10-12 hour, take out and put into 25-30 DEG C of warm water immersion 12 hours, pull out, again put into refrigerator and cooled and hide 8-10 hour, take out and be reentered in the warm water of 20-25 DEG C and soak 8-10 hour, then pull out to enclose with gauze and put into presprouting of seeds case, at 20-30 DEG C, constant temperature vernalization 12-24 hour, takes out;
(5) seed after constant temperature vernalization is being mixed thoroughly with rare earth, and concrete grammar, for after being joined by 3g nitric acid rare earth and stirring in 40g water, adds 3kg seed, fully mix thoroughly, then seed and fine earth are mixed thoroughly by the weight ratio of 1:3, are seeded in seedbed according to a conventional method,, within 3-4 days, germinate.
Wherein, nutrient liquid is formulated by following component; often liter of nutrient solution comprises the component of following weight: ferrous sulfate 0.3-0.5g, ammonium molybdate 0.2-0.3g, zinc sulphate 0.01-0.03g, manganese sulphate 0.01-0.03g, cupric sulfate pentahydrate 0.2 ~ 0.4g, vitaminB10 .02-0.03g, vitamin c 1-2g, taurine 0.3-0.5g, calciferol-5mg, vitamin E 0.4-0.7g, ferrous sulfate 2-4g, and surplus is water.
