Abstract
The invention discloses a cold-humid adversity resisting tobacco coated seed and a preparation method thereof. Before being subjected to coating and pelleting, the tobacco seed is initiated by using mixed solution consisting of 5 to 10g/L urea hydrogen peroxide and 50 to 100mg/L gibberellin; and when coating and pelleting is performed, 10.0 to 20.0 percent calcium peroxide is added into a seed coating agent. The cold-humid adversity resisting tobacco coated seed prepared by the invention has the advantages of high seed activity, short sprouting time, high rate of emergence in the fame, uniform emergence of seedlings, high resistance to low temperature stress and hyproxia stress, and the like, and has excellent application prospect in the tobacco production.
Description
Technical field
The invention belongs to tobacco seed dressing processing technique field, be specifically related to a kind of cold-humid adversity resisting tobacco coated seed that especially is fit to the cold wet environment of growing seedlings.The invention still further relates to the preparation method of this cold-humid adversity resisting tobacco coated seed simultaneously.
Background technology
Tobacco floating seed rearing is an advanced person's in the leaf tobacco production a seedling growing process, and its production efficiency is high, tobacco seedling growth is neat, is suitable for the specialization and the large-scale production of tobacco leaf.Since nineteen ninety-six, follow the fast development of China's leaf tobacco production, the tobacco floating seed rearing technology is popularized very rapidly on leaf tobacco production.
For ease of sowing, the general tobacco seed-coating seed that adopts on the leaf tobacco production.Early stage tobacco seed-coating seed mainly is that along with the renewal and the conversion of seedling raising manners, conventional tobacco seed-coating seed can not adapt to the demand that modern tobacco agriculture is produced to conventional seedbed system technology and Development and Production.At first, temperature is lower between China's big cigarette district nursery stage, and often meets bad weathers such as sleet is freezing; Cause temperature of fry nursing pool lower, even can cause larval rearing water to freeze, make the germination rate of capsuled seed reduce; Emerge slowly, it is irregular to emerge, a little less than the growing way; Even do not emerge, have a strong impact on normal leaf tobacco production, bring the tremendous economic loss for country and tobacco grower.Secondly; The health of tobacco seed is sprouted and growth of seedling all needs sufficient oxygen, owing to adopt floating mode to grow seedlings, seedling medium is full of moisture; Gas permeability is poor; Capsuled seed is immersed in the open fire for a long time, the germination of seed and growth of seedlings has been formed hypoxemia coerced, and has influenced the raising of floating seedlings quality.
Conventional tobacco seed-coating seed is lower to the anti-anti-ability of the cold wet environment stress that floating seedlings is met often, is difficult to satisfy the technical quality requirement of floating seedlings to tobacco seed, is restricting the fast development of leaf tobacco production.Therefore, develop and develop the cold-humid adversity resisting tobacco coated seed that suits the floating seedlings technical characterstic and become problem demanding prompt solution in the present leaf tobacco production.
Summary of the invention
The objective of the invention is to deficiency, a kind of cold-humid adversity resisting tobacco coated seed that especially is fit to the cold wet environment of growing seedlings is provided to tobacco floating seed rearing characteristics and prior art.
The present invention also aims to provide a kind of method for preparing said cold-humid adversity resisting tobacco coated seed.
The object of the invention is achieved through following technical scheme.
Except as otherwise noted, the percentage that the present invention adopted is percetage by weight.
A kind of cold-humid adversity resisting tobacco coated seed is characterized in that: contain 10.0～20.0% calper calcium peroxide in the kind clothing agent of this capsuled seed; And tobacco seed uses the mixed solution of 5～10g/L carbamide peroxide and 50～100mg/L gibberellin to cause earlier before carrying out dressing processing.
Prepare the method for said cold-humid adversity resisting tobacco coated seed, may further comprise the steps:
1, causes: tobacco seed is put into 100 times the 5～10g/L carbamide peroxide and the mixed solution of 50～100mg/L gibberellin, constantly stir, under 25 ℃ of illumination conditions, cause 24～36h; After cause finishing, with clear water seed is cleaned, at room temperature Hui Gan is to water content 4.0～7.0%, and is subsequent use;
2, dressing processing: in kind of clothing agent, add 10.0～20.0% calper calcium peroxide; Mix; Tobacco seed after the initiation processing by conventional dressing processing technology, promptly after dressing, nucleation, Pelleting, typing, polishing, dyeing and the drying, is obtained required cold-humid adversity resisting tobacco coated seed.
The present invention is easy and simple to handle, and is with low cost.Advantage such as the anti-drag that cold-humid adversity resisting tobacco coated seed has vigor height, germinating time weak point, field emergence rate height, the neat and consistent of emerging, coerce low temperature stress and hypoxemia is strong has a good application prospect on leaf tobacco production.
