Peanut seed dressing method
A, the seed
The seed disinfection with agents can choose according to local often occurrence of plant diseases and insect pests, general agent seed can choose 70% wettable powder of methyl sulfur bacteria spirit, or 50% carbendazim wettable powder, wettable powder or 40% seed spirit, according to 0.3% ~ 0.5% and the amount of seeds which can effectively prevent roots rotted seedlings death;Seeds with 50% phoxim emulsifiable solution according to the amount of seed, 0.2% with 40% dimethoate ec 250 ~ 400 grams, add water 5 kg, 100 kg, can control underground pest;Press with kerosene or diesel seed amount of 0.1% ~ 0.2% and can ward off effect, can prevent underground pests and birds and animals damage seeds, improve the germination rate.
Chloride with "worm benzamide + imidacloprid (optimal mix)" the seed, to be effective in control of grubs (aphids, cutworms, wireworm, and the earth, the second generation bollworm, etc.Method is to choose a good peanut bask in a kind of 2 ~ 3 days in advance, and then, get rid of the mildew, germination, and explodes the skins, seeds of fissure.In accordance with the RMB $15 kg of peanuts, with chlorine worm benzamide 30 ml, 10 ml and imidacloprid in 250 ~ 300 ml water.Find a premixed, add 1/3 of the total water, chlorine will worm benzamide pour into the beaten, then combine imidacloprid.Add with good solution slowly into the peanut seeds, pour and stir until blended.Will mix of peanut seed quickly moved to the ventilated place dry, can dry in about 10 minutes, after air seeding can be achieved.
Second, water retention agent seed dressing
Peanut, water retention agent is a kind of high polymer absorbent resin is a kind of excellent water material, can absorb seed moisture of hundreds of times its own weight, thinner drought so used, general could increase by about 10%.Method is: use before you will be wet peanut seeds, according to 150 ~ 300 g per acre aquasorb evenly over the surface of the seeds, then mix well.Or for seed coating, amount to 100 ~ 150 g per acre.According to the dosage and the bibulous rate of super absorbent polymers, calculating and measuring the water, the water retention agent to join the water slowly, and while stirring constantly, make water retention agent quickly swell, until the water and water retention agent evenly mix into a paste;Then in peanut seeds, pour while stirring, mix well after diluted dry in BeiBo.
Third, KangHanJi seed dressing
The popularization and application in our country at present is mainly KangHanJi 1, the main chemical composition is fulvic acid.General reagent dosage is 0.5% of the amount of seed, water addition 10% of the amount of seed.Use a small amount of warm water first KangHanJi 1, tune into a paste, add water to the quantitative, stirring constantly to be completely dissolved, then stir in peanut seeds and pile sown in 2 ~ 4 hours.If you don't immediately sowing, to the seed dry.
Four, rhizobia seed dressing
Rhizobia agent is a kind of biological preparation, seed dressing by rhizobia agent, can obviously improve the root number of tumor and nitrogen fixation ability, increase production.Peanut rhizobia agents by seed dressing, general could increase by about 10%, the crop of the ground application effect is better.The rhizobia agent has two kinds of powder and liquid, powder dosage for 100 grams per acre, fluid of 50 grams, bacteria per gram agent in more than 200 million living bacterium content requirements.Use, first to bacterium agent to add some water to make, and then fall on the seeds, fully mixing bacterium agent and peanut seeds, until every grain of peanut seed gelling fluid of bacteria powder or bacteria.The seed to do increases with the increasing mix sowing, don't contact with pesticides, ammonium sulfate, lime, etc, so as not to kill the rhizobia.Sow seeds to use wet cloth cover, to prevent sun, affect the rhizobia vitality, after seeding to cover soil in a timely manner.Rhizobia, after the seed YongZhongLiang reoccupy is 0.5 ~ 1.0 kg per mu gypsum seed, can enhance anti-reversibility of rhizobium, and improve the production effect of the seed.
Fifth, indicated that the seed
Can peanut seeds by indicated coating, sterilization, pest control, improve the seed vigor, avoid or mitigate adverse environmental impact, is beneficial to peanut seedling qi, miao, healthy, promote seedling early.The indicated on the market at present a lot of more phyletic, should choose to suit their own characteristics according to the different situation of indicated.If use 21% compound cough up the fungus nitrile indicated, dosage of medicine, a ratio of 1:350.Best day before the planting of coating, coating in the afternoon or morning sow, so that the dry seeds on the surface.Indicated after the coating seed germination speed will slow down, so should choose strong vitality, high germination rate of seeds, so as to avoid waste of reagents and seeds.Indicated that contains aposematic, shows that its contain toxic substances.Therefore, in the operation, should be paid attention to when to properly handle the appliance after each operation.
Peanut seed points for attention
A good grasp of the dose of a drug overdose of avoid by all means cause phytotoxicity;
Second, immediately after the mixed seeding, cannot be stored for a long time;
3 it is to properly handle the rest of the seeds, prevention and cure are livestock and poultry consumption, to ensure safety.
