Abstract
The invention discloses an oxygenation type coated and pilled tobacco seed and preparing method thereof. Before the tobacco seed is coated and pilled, the tobacco seed can be performed for oxygenationinitiating by using 0.5 %-1.0% calcium dioxide turbid fluid. When coating and pilling, 10.0 %-20.0% of calcium dioxide can be added in a seed agent. The oxygenation type coated and pilled tobacco see d made by the invention can be applied to the tobacco float seedling cultivation, the invention has advantages of high seed activities, short germinating time, trim emergence of seedlings and high emergence rate, the operation is simple, the cost is low, the popularization and the application of the technology have good social and economic benefits.
Description
Technical field
The invention belongs to tobacco seed dressing Pelleting technical field, be specifically related to a kind of aeration-type tobacco seed-coating pelleted seed that can in the tobacco seed germination process, slowly discharge oxygen.The invention still further relates to the preparation method of this aeration-type tobacco seed-coating pelleted seed simultaneously.
Background technology
Tobacco floating seed rearing is the seedling growing process of an advanced person in the leaf tobacco production, and its production efficiency height, tobacco seedling growth are neat, are suitable for the specialization and the large-scale production of tobacco leaf.China is since 1996 begin to promote the tobacco floating seed rearing technology, and this technology is followed the fast development of China's leaf tobacco production, popularizes rapidly.
For ease of sowing, the general tobacco seed-coating pelleted seed that adopts on the leaf tobacco production.Early stage tobacco seed-coating pelleted seed is at the conventional seedbed system technological development.Along with the renewal and the conversion of seedling raising manners, conventional tobacco seed-coating pelleted seed can not adapt to the demand that modern tobacco agriculture is produced.Because levitating seed-cultivating interstitial substance is full of moisture, seed is immersed in the open fire for a long time, seed is formed hypoxemia coerce, make seed germination and growth of seedling can't obtain sufficient oxygen, problems such as seed vitality is low, germinating time long, the regularity of emerging is poor, emergence rate is low occur.Therefore, how the tobacco pelleted seed when sprouting provides sufficient oxygen, improves seed vitality, alleviates hypoxemia and coerce the injury that seed is caused and just become the technical problem that this area needs to be resolved hurrily.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of aeration-type tobacco seed-coating pelleted seed that can slowly release oxygen in the tobacco seed germination process is provided.
The present invention also aims to provide a kind of method for preparing described aeration-type tobacco seed-coating pelleted seed.
Purpose of the present invention is achieved by the following technical programs.
Except as otherwise noted, percentage of the present invention is percetage by weight.
A kind of aeration-type tobacco seed-coating pelleted seed is characterized in that: contain 10.0%～20.0% calper calcium peroxide in the kind clothing agent of this coat pelleted seeds; And tobacco seed is before carrying out dressing Pelleting processing, and the turbid liquid of calper calcium peroxide of use 0.5%～1.0% carries out the oxygenation initiation earlier.
Prepare the method for described aeration-type tobacco seed-coating pelleted seed, may further comprise the steps:
1, oxygenation cause to be handled: with seed, calper calcium peroxide and water according to mass ratio 1.0～5.0: 0.5～1.0: 99.5～99.0 ratio is evenly mixed, and constantly stirs, and causes 24～36h under 25 ℃ of illumination conditions.After cause finishing, with clear water seed is cleaned, at room temperature Hui Gan is to water content 4.0%～7.0%, and is standby;
2, dressing Pelleting processing is handled: add 10.0%～20.0% calper calcium peroxide in kind of clothing agent, mix, with the tobacco seed Pelleting processing technology routinely after the oxygenation initiation processing, after being dressing, nucleation, Pelleting, typing, polishing, dyeing and drying, obtain required aeration-type tobacco seed-coating pelleted seed.
Have following advantage with respect to prior art the present invention:
1, add calper calcium peroxide when tobacco seed causes and carry out the oxygenation initiation, and add calper calcium peroxide as the oxygenation agent in dressing Pelleting process, sprouting for tobacco seed provides sufficient oxygen, and then improves seed vitality and seedling quality.A large amount of experiments show that the germination vigor of aeration-type tobacco seed-coating pelleted seed, germination rate, seedling length and seedling dry weight have increased by 3.0～4.6%, 1.7～3.0%, 11.9～32.3% and 15.4～41.4% than conventional tobacco seed-coating pelleted seed respectively.
2, after aeration-type tobacco seed-coating pelleted seed is applied to floating seedlings, have seed vitality height, germinating time short, emerge neat, emergence rate advantages of higher.
3, the present invention is easy and simple to handle, and is with low cost, has a good application prospect on leaf tobacco production.
