A kind of muskmelon seeds germination accelerating method
Technical field
The present invention relates to vegetable growing field, be specifically related to a kind of muskmelon seeds germination accelerating method.
Background technology
The seed demand vernalization of a lot of vegetables, melon and fruit, 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, wax gourd, watermelon etc.; 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, muskmelon, garlic etc.Different vegetables, vernalization mode difference separately.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, Miao Zhuan.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 muskmelon seeds germination accelerating method, this germination accelerating method can not only improve percentage of seedgermination, shortens germination time, alleviates Field diseases, plants the sugary height of ripe muskmelon simultaneously, and individuality is larger, and output is high, and shelf time is long.
The technical solution used in the present invention is:
A kind of muskmelon seeds germination accelerating method, is characterized in that, comprises the following steps:
(1) prior to seeding seed is shone after 10-12 hour, select the seed of full seed, the seed of select is put in container, in clear water, under normal temperature, soak 5-6 hour, then drop into the 30-40 minute that soaks seed in seed soaking agent, pull out clean, wherein seed soaking agent is formulated by following component, the percentage by weight of each component is: 6-benzyl aminopurine 100-200ppm, 2 chloroethyl phosphoric acid 20-40ppm, three decane alcohol 10-15ppm, potassium nitrate 1%-2%, α-naphthaleneacetic acid 3-5ppm, paclobutrazol 8-10ppm, brassin lactones 4-6ppm, dipotassium tetraborate 0.1%-0.5%, surplus is water, after being dissolved in respectively to water, each component mixes, be diluted with water to desired concn, stir and get final product,
(2) seed soaking is put into the container that fills nutrient solution again, container is put into 600w microwave equipment, with 60% firepower microwave treatment 5-6 second, then stop microwave treatment, take out under normal temperature and soak 2-3 hour in nutrient solution; ;
(3) clean with clear water again;
(4) above-mentioned soaked seed is bound up with gauze, squeeze and remove part moisture, put into refrigerator at 2-4 DEG C of refrigeration 10-12 hour, then take out and put into rapidly the warm water of 20-25 DEG C and soak 1-2 hour, pull out, refrigeration again, 3-4 time so repeatedly, then pull out with bundle and and put into presprouting of seeds case, at 25-28 DEG C, constant temperature vernalization 10-12 hour, takes out;
(5) seed after constant temperature vernalization is mixed thoroughly with rare earth again, 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 into according to a conventional method in seedbed, mulching straw, spray again permeablely, generally within 3-4 days, can germinate
Nutrient liquid described in step (2) is formulated by following component, and every liter of nutrient solution comprises the component of following weight: potassium dihydrogen phosphate 0.3-0.5, borax 0.3-0.5g, ammonium molybdate 0.2-0.3g, ZnSO
47H
2o 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 sulfate 0.3-0.6g, 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, has improved the germination rate of muskmelon seeds greatly, and germination rate can reach more than 100%, the muskmelon of planting out through this germination accelerating method, and the ripe sugary height of muskmelon, individuality is larger, and output is high, and shelf time is long.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 muskmelon seeds germination accelerating method, is characterized in that, comprises the following steps:
(1) prior to seeding seed is shone after 10-12 hour, select the seed of full seed, the seed of select is put in container, in clear water, under normal temperature, soak 5-6 hour, then drop in seed soaking agent and soak seed 35 minutes, pull out clean, wherein seed soaking agent is formulated by following component, the percentage by weight of each component is: 6-benzyl aminopurine 120 ppm, 2 chloroethyl phosphoric acid 30ppm, three decane alcohol 13ppm, potassium nitrate 1%, α-naphthaleneacetic acid 4ppm, paclobutrazol 9ppm, brassin lactones 5ppm, dipotassium tetraborate 0.4%, surplus is water, after being dissolved in respectively to water, each component mixes, be diluted with water to desired concn, stir and get final product,
