Description
Technical field
The invention belongs to agriculture application, relate to rape humidity coating agent for seed, also relate to the application of this coating agent for seed under stain wets condition.
Background technology
Rape is the important oil crop of China, and output and sowing area all occupy first place in the world, and is important edible oil sources and protein feed source, simultaneously or the important raw material of industry.The Yangtze river basin is the main growing area of China's rape, but this district's Rape-seed production has following several large feature: one is adopt rice-rape rotation more, and after paddy rice harvesting, Tanaka's moisture is not easily discharged, to after do growth of rape produce wet injury; Two is that winter is moistening rainy, easily there is wet injury and damage caused by waterlogging in rape seedling, have a strong impact on the output of rape, main manifestations is the height of seedling of rape, stem is thick, greenery number, leaf area and dry weight reduce serious, have a strong impact on the yield and quality of rape, wet injury environment also can aggravate infecting and expansion of grave illness bacterium simultaneously; Three is that south about has the Winter paddy field of 300,000,000 mu, is wherein manyly low-lyingly unfavorable for seedling growth of rice due to moistening and is not utilized.
It is improve cultivation step that the method current production alleviating rape wet injury mainly contains two kinds: one, dig trenches to drain the water away as adopted, the narrow railway carriage or compartment of Soil tillage, zanjon and intertillage are loosened the soil etc. reduces soil moisture, but this will consume a large amount of human and material resources, production cost is finally caused to increase, earning rate reduces, and farmer concepts declines; Two is breeding measures, cultivated the rape variety of high-quality, high moisture-proof, but the breeding time limit is often longer by the method for breeding, and the moisture-proof stability of kind is also unreliable.Wet resistance research for rape mainly concentrates on wet resistance qualification aspect at present, and Japanese river in 1987 is former to be reported and rape seed is put into cold boiling water germinate, and represents the power of wet resistance with the height of germination factor; Lu Changming in 1989 etc. also use the same method and to identify rape humidity resource.But said method adopts dry seed directly to soak due to it, can not eliminate the impact of seed dormancy and seed coat difference, and only can not authentic assessment wet resistance using germination rate as evaluation index.After this, the people such as people and Chen Jie such as Fan Qixin, showed money or valuables one carries unintentionally by the rape just germinateed after seed puts into distilled water waterlogging and continue to germinate at filter paper bed, the hypoxia-bearing capability of the growing points such as direct-detection radicle is the kind that main criterion filters out different moisture-proof degree with vitality index.Then carry out waterflooding and non-submerging treatment to the kind of these moisture-proof degree, process terminates to compare phenotype index and Determination of Physiological And Biochemical Indices afterwards.
Seed pelleting improves a kind of short-cut method of seed quality, but it is less to utilize coating agent for seed to improve the research of the water-logging resistance of the germination rate of rape under wet-out conditions and seedling.Therefore, be badly in need of one both easy, the coating agent for seed for rape seed economic again, can improve the moisture resistance of rape.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of rape humidity coating agent for seed, solve the technical problem that China's rape main growing area wet injury is serious.
For achieving the above object, the invention provides following technical scheme:

Preferred, the raw material following by concentration forms, Determination of Salicylic Acid is 0.1 ~ 0.5mmol/L, N-(2-benzimidazole base)-methyl carbamate percentage by weight is 0.01 ~ 0.05%, boric acid percentage by weight is 0.1 ~ 0.2%, and carboxymethyl cellulose percentage by weight is 2%, and talcum powder percentage by weight is 8 ~ 10%, pigment weight percentage is 0.5 ~ 1%, and surplus is water.
Most preferred, the component following by concentration forms: salicylic acid 0.5mmol/L, N-(2-benzimidazole base)-methyl carbamate percentage by weight is 0.02%, boric acid percentage by weight is 0.2%, carboxymethyl cellulose percentage by weight is 2%, talcum powder percentage by weight is 10%, pigment weight percentage is 0.5%, surplus is water.
Two of object of the present invention is to provide rape humidity coating agent for seed improving the application in rape seed germination rate, and technical scheme is:
Described rape humidity coating agent for seed improves the application in rape seed germination rate under stain wets condition.
Rape seed can be the rape seed of any kind, and preferably, described rape seed is cabbage type rape seed.
Three of object of the present invention is to provide rape humidity coating agent for seed improving the application in Brassica Napus Seedling seedling waterlogging tolerance, and technical scheme is:
Described rape humidity coating agent for seed improves the application in Brassica Napus Seedling waterlogging tolerance under stain wets condition.
Brassica Napus Seedling can be the rape seed of any kind, and preferably, described Brassica Napus Seedling is seedlings of Brassica napus L.
Four of object of the present invention is to provide rape humidity coating agent for seed improving the application in yield of rape, and technical scheme is:
Described rape humidity coating agent for seed improves the application in yield of rape under stain wets condition.
Beneficial effect of the present invention is: rape humidity coating agent for seed disclosed by the invention, its uniqueness of filling a prescription, salicylic acid in seed coating medicine by reducing rape leaf membrane permeability, improving the content of leaf water content, chlorophyll content, improving activity of root system and three kinds of osmotic field, thus improves the germination rate of rape seed and the moisture resistance of Brassica Napus Seedling; N-(2-benzimidazole base)-methyl carbamate has broad spectrum antibiotic activity, can under stain wets condition pre-insect-pest; Also contain boric acid in coating agent for seed simultaneously, improving activity of root system and blade Determination of Chlorophyll content can be increased, by salicylic acid, N-(2-benzimidazole base)-methyl carbamate and boric acid mixes under certain proportion, and add carboxymethyl cellulose in conjunction with seed coating technology and make coating agent for seed as film forming agent surfactant of holding concurrently, active ingredient can be attached to the surface of the seed thus reach and improve the wet performance of the anti-stain of rape, thus arrive the object improving yield of rape and oil content; Be used for by the coating agent for seed made after cabbage type rape seed carries out dressing, can improve percentage of seedgermination 15 ~ 30% under stain wets condition, yield of rape improves 10-15%.
In addition, utilize the method for coating agent for seed of the present invention simple, with low cost, there is operability, rape disease can be prevented under stain wets condition, rape neat seedling in strong sprout can also be promoted simultaneously, thus improve the output of rape, increase the income of peasant.
