A kind of tomato seeds germination accelerating method
Technical field
The present invention relates to field of vegetable, be specifically related to a kind of tomato seeds 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, tomato, 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, tomato, 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 tomato seeds germination accelerating method, this germination accelerating method can not only improve percentage of seedgermination, shortens germination time, alleviate Field diseases, seedling seedling be neat, Miao Zhuan, improve output, add the nutrient composition content of tomato simultaneously, further increase the quality of tomato.
The technical solution used in the present invention is:
A kind of tomato seeds germination accelerating method, is characterized in that, comprise the following steps:
(1) after seed being shone 1-2 days in 8-10 days prior to seeding, 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 and soak 20-30 minute, take out and clean, wherein seed soaking agent is formulated by following component, the percentage by weight of each component is: chitosan oligosaccharide 20-30ppm, gibberellin 6-9ppm, brassin 1-3ppm, compound sodium nitrophenolate 10-15PPm, jasmonic 8-10ppm, carbendazim 20-30ppm, vitamin C 10-15ppm, zeatin 5-10ppm, hydrogen peroxide 20-30ppm, borax 0.2-0.4%, surplus is water, mix after each component is dissolved in water respectively, be diluted with water to desired concn, stir and get final product;
(2) seed soaked is put into the container filling nutrient solution again, container is put into 600w microwave equipment, the firepower microwave treatment with 60% 10 seconds-20 seconds, then stops microwave treatment, soaks 5-6 hour under taking out normal temperature;
(3) rinse with clear water, drift decontamination, till water is clear 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, taking-up is put into 30-35 DEG C of warm water and is soaked 12 hours, pulls out and again puts into refrigerator and cooled Tibetan 8-10 hour, take out to be reentered in the warm water of 30-35 DEG C and soaks 8-10 hour, then pull out to enclose with gauze and put into presprouting of seeds case, at 20-25 DEG C, constant temperature vernalization 60-65 hour, takes out;
(5) seed after constant temperature vernalization is being mixed thoroughly with rare earth, concrete grammar is for after joining 3-4g rare earth and stirring in 40-50g water, add 2.5-3.5kg 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, mulching straw, spray permeable again, within general 6-7 days, can germinate.
Described tomato seeds germination accelerating method, is characterized in that:
Nutrient liquid described in step (2) is formulated by following component; often liter of nutrient solution comprises the component of following weight: borax 0.3-0.5g, ammonium molybdate 0.2-0.3g, ZnSO47H2O0.2-0.5g, 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 gluconate 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, the speed of tomato seeds is fast, and the growth of bud seedling is neat, and after transplanting, field damage by disease and insect is few, and the field Anti-temperature difference changing capability of tomato is strong.The tomato vitamin content of planting out through this germination accelerating method is high.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 tomato seeds germination accelerating method, comprises the following steps:
(1) after seed being shone 1-2 days in 8-10 days prior to seeding, 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 and soak 20-30 minute, take out and clean, wherein seed soaking agent is formulated by following component, and the percentage by weight of each component is: chitosan oligosaccharide 25ppm, gibberellin 8ppm, brassin 2ppm, compound sodium nitrophenolate 14PPm, jasmonic 9ppm, carbendazim 25ppm, vitamin C 13ppm, zeatin 8ppm, hydrogen peroxide 26ppm, borax 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) seed soaked is put into the container filling nutrient solution again, container is put into 600w microwave equipment, the firepower microwave treatment with 60% 10 seconds-20 seconds, then stops microwave treatment, soaks 5-6 hour under taking out normal temperature;
(3) rinse with clear water, drift decontamination, till water is clear again;
(4) above-mentioned soaked seed is bound up with gauze, squeeze and remove portion of water, put into refrigerator 4 DEG C of refrigerations 11 hours, taking-up is put into 30-35 DEG C of warm water and is soaked 12 hours, pulls out and again puts into refrigerator and cooled Tibetan 8-10 hour, take out to be reentered in the warm water of 30-35 DEG C and soaks 8-10 hour, then pull out to enclose with gauze and put into presprouting of seeds case, at 20-25 DEG C, constant temperature vernalization 60-65 hour, takes out;
(5) seed after constant temperature vernalization is being mixed thoroughly with rare earth, concrete grammar is for after joining 3.5g nitric acid rare earth and stirring in 45g water, add 3.0kg 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, mulching straw, spray permeable again, within general 6-7 days, can germinate.
Wherein, nutrient liquid is formulated by following component; often liter of nutrient solution comprises the component of following weight: borax 0.4, ammonium molybdate 0.2g, ZnSO47H2O0.4g, cupric sulfate pentahydrate 0.3g, vitaminB10 .02g, vitamin C 1.5g, taurine 0.4g, vitamine D4 mg, vitamin E 0.5g, ferrous gluconate 3g, and surplus is water.
