The low-temperature cold-resistant agent can resist the low temperature of-2 to-5 ℃ for 10 hours, and is suitable for seedling culture of crops such as cotton, rape, vegetables, rice, flue-cured tobacco, watermelon and the like.
Description
The invention belongs to the plant growth regulator technical field, relate in particular to by dextrin, plant hormone, plant growth regulator and mineral salt, polysaccharide etc. mix the plant low temperature protectant of forming.
The rice seed soaking cold-resistance agent of Xiao Shouing in the market, territory of use is on the south the Changjiang river, be mainly used in and soak rice paddy seed when rice seedling is cultivated, the rice paddy seed that this cold-resistance agent of process soaked, can only resist the low temperature more than 0 ℃, can not resist the low temperature below 0 ℃, this cold-resistance agent can not use in the seedling cultivation process of crops such as vegetables, watermelon, tobacco in temperature area to the north of the Changjiang river.
The objective of the invention is to overcome the shortcoming of above-mentioned rice seed soaking cold-resistance agent, a kind of plant low temperature protectant that the region is big, purposes is wide that uses is provided.
For achieving the above object, the scheme that the present invention adopts is: with nitrate of lime, potassium nitrate, magnesium sulfate, potassium dihydrogen phosphate, glycerine, agar, sucrose, molecular weight is that 6000 polyethylene glycol, chlormequat, penicillin, dimethyl sulfoxide (DMSO), mercaptoethanol, gelatin, dextrin, plant hormone and plant growth regulator are mixed and made into.
Dextrin in the mixed composition of the present invention is alpha-cyclodextrin or beta-schardinger dextrin-or gamma-cyclodextrin, and plant hormone is an abscisic acid, brassinosteroid or courage steroid lactone, and plant growth regulator is ethrel or paclobutrazol.
In mixed composition of the present invention, the weight ratio of alpha-cyclodextrin or beta-schardinger dextrin-or gamma-cyclodextrin and abscisic acid is 1: 0.000264～0.00264, the weight ratio of alpha-cyclodextrin or beta-schardinger dextrin-or gamma-cyclodextrin and brassinosteroid or courage steroid lactone is 1: 0.000001～0.00001, and the weight ratio of alpha-cyclodextrin or beta-schardinger dextrin-or gamma-cyclodextrin and ethrel or paclobutrazol is 1: 0.006～0.01.In mixed composition of the present invention, the weight ratio of alpha-cyclodextrin or beta-schardinger dextrin-or gamma-cyclodextrin and other component of the present invention is: with the weight ratio of nitrate of lime be 1: 0.08, be respectively 1: 0.02 with the weight ratio of potassium nitrate, magnesium sulfate, potassium dihydrogen phosphate, with glycerine, sucrose, agar, molecular weight be that the weight ratio of 6000 polyethylene glycol, mercaptoethanol, dimethyl sulfoxide (DMSO), gelatin was respectively 1: 0.01, with the weight ratio of chlormequat be 1: 0.003, with the weight ratio of penicillin (800,000 unit) be 1: 0.1.
For making seed selection plant low temperature protectant, can adopt following method.
1. take by weighing
Take by weighing alpha-cyclodextrin or beta-schardinger dextrin-or gamma-cyclodextrin, abscisic acid, brassinosteroid or courage steroid lactone, ethrel or paclobutrazol, nitrate of lime, potassium nitrate, magnesium sulfate, potassium dihydrogen phosphate, glycerine, sucrose, agar-agar, molecular weight in proportion and be 6000 get ethylene glycol, chlormequat, penicillin, dimethyl sulfoxide (DMSO), mercaptoethanol, gelatin.
2. mix
The alpha-cyclodextrin that taken by weighing or beta-schardinger dextrin-or gamma-cyclodextrin are poured in the molten device, and the water that adds 2 times stirs at normal temperatures and pressures with the stainless steel agitator, makes it become pasty state.Be that 60000 polyethylene glycol, abscisic acid, brassinosteroid or courage steroid lactone are put into three molten devices respectively again with molecular weight, add ethanolic solution then respectively till the dissolving fully, be mixed with molecular weight and be 6000 polyethylene glycol ethanolic solution, abscisic acid ethanolic solution, brassinosteroid or courage steroid lactone ethanolic solution.
With the nitrate of lime, potassium nitrate, magnesium sulfate, potassium dihydrogen phosphate, glycerine, agar-agar, sucrose, penicillin (800,000 unit), dimethyl sulfoxide (DMSO), mercaptoethanol, gelatin, chlormequat, ethrel or the paclobutrazol that have taken by weighing and the molecular weight that has prepared be 6000 get ethylene glycol ethyl ethers alcoholic solution, abscisic acid ethanolic solution, brassinosteroid or courage steroid lactone ethanolic solution, pour alpha-cyclodextrin or the beta-schardinger dextrin-or the gamma-cyclodextrin of the pasty state that has prepared respectively into, stirred 2 hours with the stainless steel agitator, it is fully mixed.Make the plant low temperature protectant of pasty state.
3. dry
With the plant low temperature protectant of Manufactured pasty state under the low temperature situation dry or with warm air drier at 30 ℃～40 ℃ low temperature dryings.The plant low temperature protectant of pasty state just condenses into bulk.
4. pulverize
Become powder with making block plant low temperature protectant with grinder or ball mill grinding.
The present invention is through laboratory and small size field trial, and result of the test shows: the present invention compares with the rice seed soaking cold-resistance agent, has advantages such as usable floor area is big, applicable crops is many, cold-resistant temperature is low, can promote the use of with the area, north temperate zone in the Changjiang river.
The inventor has provided a most preferred embodiment of the present invention.
In giving the mixed composition of invention, alpha-cyclodextrin or beta-schardinger dextrin-or gamma-cyclodextrin select for use the rape lactone of beta-schardinger dextrin-, plant hormone or courage steroid lactone to select brassinosteroid for use, and the ethrel or the paclobutrazol of plant growth regulator are selected ethrel for use.Present embodiment mixes in following ratio.
The weight ratio of beta-schardinger dextrin-and abscisic acid is 1: 0.000264, and the weight ratio of beta-schardinger dextrin-and brassinosteroid is 1: 0.000001, and the weight ratio of beta-schardinger dextrin-and ethrel is 1: 0.006.In mixed composition, beta-schardinger dextrin-and other component of the present invention, nitrate of lime, potassium nitrate, magnesium sulfate, potassium dihydrogen phosphate, glycerine, sucrose, agar, molecular weight be 6000 polyethylene glycol, mercaptoethanol, dimethyl sulfoxide (DMSO), gelatin, chlormequat, penicillin weight ratio as hereinbefore.
The plant low temperature protectant that the inventor adopts the mixed proportion of present embodiment to make is tested in laboratory and field.
1. the preparation of plant low temperature protectant solution
Manufactured plant low temperature protectant is put into molten device, and the water that adds 98.75: 1 temperature and be 50 ℃ dissolves it fully, is mixed with the plant low temperature protectant aqueous solution.
2. test method
