Abstract
The invention relates to a seed treatment method and storage technology, in particular to a comprehensive priming method and storage technology for solanceous vegetable seeds. The priming method for solanceous vegetable seeds includes: using biopesticide trichoderma harzianum T-22 as a bio-priming agent, mixing seeds, vermiculite and a trichoderma harzianum T-22 aqueous solution evenly in a ratio of 1:3:3-3.4, with the dosage of trichoderma harzianum T-22 being 1*10<6>-3*10<6>CFU/gram of seeds, conducting priming under a 15DEG C dark condition for 5-8 days, and performing dehydration at 25DEG C for 2 days. The seed storage technology is characterized in that the seeds are stored in a low oxygen environment by vacuum pumping.
Description
Technical field
The present invention relates to a kind of method for treating seeds and storage technique, more particularly to a kind of synthesis initiation for solanaceous vegetables seed
Method and storage technique.
Background technology
Fructus Capsici, Fructus Lycopersici esculenti and Fructus Solani melongenae are the important solanaceous vegetables crops of China.Solanaceous vegetables seed kind skin has thicker horny layer,
Germination is relatively difficult, and germinating time is long, germinates irregular.Especially under adverse environmental factor, germination problem is more projected.
Such as under the conditions of low temperature and salination, percentage of seedgermination is low, and germinating time extends, and planting percent is low, emerges irregular, seedling life
Length is suppressed, and then has a strong impact on vegetable yields and quality.
The ultimate principle of seed priming is that control seed slowly absorbs water so as to rests on the second stage of imbibition, allows seed to carry out pre-
The Physiological and Biochemical Metabolism of germination and repair, promote cell membrane, organelle, the reparation of DNA and the activation of enzyme, are allowed to be in
The metabolism state of germination but prevent stretching out for radicle.While biological initiation controls seed water suction during being initiation, using beneficial true
Bacterium or antibacterial or the two use as seed protectant simultaneously, allow its amount reproduction, be covered with the surface of the seed, make seedling from being harmful to
The invasion and attack of bacterium, while promoting plant growth.Initiation process is carried out to seed before nursery, seed planting percent can be improved, accelerate
Seedling speed and regularity, increase yield, improve resistance.Seed vitality is improved, it is possible to reduce mu sowing quantity in nursery, is reduced
With kind of a cost, reduce due to seeding ratio difference and filled the gaps with seedlings spent labor cost and substrate cost, due to speed of emerging
Degree is accelerated, and emerges neat, and seedling raise period shortens, and nursery benefit is improved.
Seed Aging causes seed sprouting slow, ultimately results in seedling exception, or even can not emerge.The storage of seeds technology is to ensure to plant
The key technology of protonatomic mass, storage practice are proper, seed can be made to keep vigorous germinating power and vigor, it is ensured that the sowing of seed
Value.After seed priming, seed vitality is improved, and field emergence is fast and neat.After seed priming, seed vitality is improved, field emergence
It is fast and neat.However, compared with undischarged seed, the storage of seeds lost of life.Research shows, when the tomato seeds for causing
It is housed in 30 DEG C 6 months, compared with the control, has postponed germination, reduced average germination percentage.Therefore, how to improve initiation kind
The shelf-life of son becomes a great problem.The principal element in the storage of seeds life-span is affected to have ambient temperature, envionmental humidity, oxygen
Gas etc..For a long time, it is to improve seed vitality, it is main using the stored seedses under low seed moisture content and temperature conditionss, and
In storage environment, oxygen concentration is little affected by concern.However, Seed Aging process includes the oxidation of lipid, cell and mitochondrial membrane
Oxidation, the oxidation of DNA, the oxidation of RNA, the oxidation of protein is the result of direct or indirect oxidation.Hypoxia is preserved
There is provided a kind of new research method and means that Priming Seeds are preserved under room temperature hypoxia condition.
Also there is preliminary study in China to solanaceous vegetables seed priming, but causes effect widely different between different seed lots, after initiation
Storage tolerance, seed longeivity do not shorten, and only focus on initiating method research, and the storage technique impact after seed priming is not had deeply
Research.Therefore, elicitation technique China at present still cannot large-scale commercial application, become China's solanaceous vegetables Seed priming techniques
The bottleneck of research.
The content of the invention
The present invention relates to a kind of seed synthesis initiating method and storage technique, can improve Germination Characteristics, shortening is averagely emerged
Time, emergence rate is improved, particularly under the conditions of low temperature and salination, improve Seedling Quality, strengthen anti-adversity ability.Using true
Empty package stored seedses can improve the storage period of seed.
1st, a kind of solanaceous vegetables seed synthesis initiating method and storage technique, it is characterised in that caused using biological initiation and Vermiculitum and combined,
Biological initiator used is biological pesticide trichoderma harzianum T-22.
2nd, seed priming method according to claim 1, it is characterised in that by seed：Vermiculitum：Trichoderma harzianum T-22 is water-soluble
Liquid is mixed with 1: 3: 3～3.4, and trichoderma harzianum T-22 consumptions are 1 × 106～3 × 106CFU/ gram of seed, be placed in 15 DEG C it is black
Cause 5～8 days under dark condition, period stirs daily, and then seed is sifted out with dusting cover, 25 DEG C times dry 2 days.
3rd, the storage of seeds technology according to claim 1, it is characterised in that make seed store in low-oxygen environment by evacuation
Hide.
Specific embodiment
The present invention is realized by following technical measures；
Example 1
Seed 5g, Vermiculitum 15g, trichoderma harzianum T-22 aqueous solution 16g are taken, trichoderma harzianum T-22 aqueous solution usage amounts are
1.5×106CFU/ gram of seed, mixes, and causes 7 days under 15 DEG C of dark conditions, and 25 DEG C are returned dry 2 days, seed after initiation is dried
It is put into seed packet evacuation sealing preserve.
Example 2
Take seed 5g, Vermiculitum 15g, trichoderma harzianum T-22 aqueous solution 16g, trichoderma harzianum T-22 aqueous solution concentrations
For 1.5 × 106CFU/ gram of seed, mixes, and causes 5 days under 15 DEG C of dark conditions, and 25 DEG C times dry 2 days.Plant after initiation is dried
Son is put into seed packet evacuation sealing preserve.
Cause effect experimental
The eggplant seed (Mexico) caused using the initiating method of example 1 in 20 DEG C of daytime temperature, under 15 DEG C of cryogenic conditions of night temperature,
After Vermiculitum initiation is processed, seeding ratio improves 57.1%, and time advance 4.9d of averagely emerging, index of emerging improve 6.2, and plant height increases
