Abstract
The invention discloses a composite type corn seed soaking agent and a use method thereof. The composite type corn seed soaking agent is prepared by fully mixing plant growth regulators and a trace element, specifically fully mixing uniconazole, compound sodium nitrophenolate and zinc sulfate heptahydrate. The use method comprises after disinfecting and washing clearly corn seeds, blending each 1 g of the seed soaking agent with 3 kg of water, soaking 1 kg of the seeds, carrying out seed soaking for 18 h at the temperature of 20 DEG C-30 DEG C, after seed soaking, filtering the drug liquid clearly, and directly seeding. Uniconazole in the seed soaking agent can effectively promote roots and strengthen seedlings and increase lodging resistance of corn by shortening stem base internodes, compound sodium nitrophenolate can effectively alleviate negative effects of single use of uniconazole, and zinc sulfate heptahydrate can effectively prevent a zinc deficiency syndrome.
Description
Technical field
The present invention relates to the compound seed soaking agent of a kind of corn, what specifically a kind of applicable corn used is the immersion class seed treatment formulations of effective constituent with plant-growth regulator and trace element.
Background technology
Corn is one of main food crop of China, is that principal home raises feed resource, is also important industrial raw material simultaneously.Corn is subject to drought and waterlogging infringement in growth early stage, and Later growth then easily occurs lodging problem.At present, educate strong sprout and resistant to lodging be improve the important means of corn yield.
For solving the problem, traditional method is seed pelleting, seed dressing and soil disinfection.Seed pelleting exists that processing requirement level is high, the shortcoming of complicated operation.Seed dressing existence stirring is difficult to evenly and damages the shortcoming of seed.There is the shortcoming that dosage is large, time-consuming, environmental pollution is heavier in soil disinfection.
Seed soaking agent production technique is simple, and easy to use, treatment capacity is large.Uniconazole is a kind of plant-growth regulator with the short strong effect of dwarfing.Uniconazole effectively can reduce plant height, shorten basal internode length thus the lodging resistance of raising corn.And be used alone the counter productive that uniconazole has speed of germination reduction, the long shortening of root.Sodium nitrophenolate can promote Cytoplasmic streaming, improves cell viability, speed of germination and root depth, effectively can alleviate the counter productive of single use uniconazole.Generally lack zinc in the calcareous soil of the north, and corn is the crop to zinc sensitivity, and adding Zinc Sulphate Heptahydrate in seed soaking agent can effective control of maize zinc deficiency.
Chinese patent discloses the relevant technologies about maize seed soaking agent, and what relate to as CN11202317 patent publication is a kind of seed soaking agent, and plant-growth regulator is single use uniconazole, and trace element is zinc sulfate.What CN1360831 patent publication related to is a kind of sweet corn seed soaking agent and using method thereof, does not add plant-growth regulator.What CN1879461 patent publication related to is a kind ofly promotes that Course of Corn Seed Germination forms the seed processing technology in strong sprout and products thereof formula, plant-growth regulator is wherein Plant hormones regulators,gibberellins, choline dichloride and paclobutrazol, trace element is zinc sulfate, and adopt the method that secondary is soaked seed, operation is comparatively complicated.What CN102612890 patent publication related to is a kind of method improving Vigor of Zea mays L. Seeds and cold tolerance, seed soaking agent principle active component is wherein Hrf albumen, main purpose improves seed vitality and cold tolerance, and the growth conditions not for corn regulates and controls.
Summary of the invention
For solving the problem, the invention provides a kind of composite type corn seed soaking agent and using method thereof.
The present invention is achieved in that
By uniconazole 1.0-1.2kg, the specification of quality of sodium nitrophenolate 24-28kg, Zinc Sulphate Heptahydrate 120-140kg carries out weighing, fully mixing, and is made into maize seed soaking agent.During seed soaking, corn seed sterilization, clean after, 1g seed soaking agent is watered 3kg and soaks 1kg seed, and 20 DEG C-30 DEG C seed soaking 18h, after seed soaking, the clean liquid of filter is directly sowed.
Beneficial effect
With seed soaking agent of the present invention be corn seed process time, the effective constituents such as the plant-growth regulator in seed soaking agent and trace element can penetrate in seed, and uniconazole wherein effectively can reduce plant height, shorten basal internode length thus the lodging resistance of raising corn.Sodium nitrophenolate effectively can alleviate the counter productive of single use uniconazole.Adding Zinc Sulphate Heptahydrate in seed-soaking liquid can effective control of maize zinc deficiency.Select the corn seed of Zheng Dan 958 kind.The quartz sand selecting particle diameter 0.1-0.5mm is matrix, modulates the 60%-80% that its water content is saturation moisture content, bed load 4cm, covers sand 2cm.Length and width are selected to be the transparent plastics germination box with cover of 13 × 19cm.One is treated to seed soaking agent process corn seed of the present invention, and another is treated to not containing the seed soaking agent process corn seed of the present invention of sodium nitrophenolate, and clear water contrasts.Every box sows 50, and repeat for 4 times, random district group arranges.Culture temperature 25-30 DEG C, humidity 40%-60%, Light To Dark Ratio is 7: 5, waters tap water 75ml/ box respectively at 5d and 9d, and 12d measures every morphological index.Result shows, after seed soaking agent process of the present invention, plant plant height is reduced to 56.1% of contrast, second leaf leaf is long is reduced to 54.8% of contrast, second leaf blade width ratio contrast increase by 31.3%, difference all reaches 1% pole conspicuous level, and this shows that seed soaking agent of the present invention can effectively reduce plant height, make blade short wide, is conducive to nurturing staff.It is that basal internode extends that plant height due to Maize Seedlings increases major embodiment, and seed soaking agent of the present invention can effectively reduce Seedling Stage plant height, just illustrates that seed soaking agent of the present invention effectively can shorten Basalinternodelength.The underground dry weight of seed soaking agent process of the present invention is than contrast increase by 32.9%, and difference reaches 1% pole conspicuous level, shows that seed soaking agent of the present invention significantly can promote root growth, short root successful.Use the seed soaking agent process of the present invention of removing sodium nitrophenolate, plant germination index is reduced to 69.9% of contrast, and root is long is reduced to 83.8% of contrast.And after using the seed soaking agent of the present invention recovering to add sodium nitrophenolate, germination index is reduced to 85.1% of contrast, root is long is reduced to 91.7% of contrast, and difference all reaches 5% conspicuous level.This shows that the sodium nitrophenolate in the present invention effectively can alleviate the counter productive of single use uniconazole.Test proves that seed soaking agent of the present invention effectively can reduce plant height, shorten Basalinternodelength, nurturing staff, promotion root growth.
