Abstract
The invention discloses a field tank-mixed synergistic drug fertilizer for preventing and treating rice spike neck blast and a spraying method thereof. The drug fertilizer is prepared from 75% tricyclazole powder, 75% trifloxystrobin.tebuconazole water dispersible granules, 1% sodium selenite solution and water by tank mixing. When in tank mixing, the 75% tricyclazole powder, 75% trifloxystrobin.tebuconazole water dispersible granules and water are sufficiently dissolved and mixed, and the 1% sodium selenite solution is stirred and mixed with the mixture. The spraying method comprises two steps of early prevention and later prevention. By adopting the drug fertilizer of the proportion, the effect in preventing and treating spike neck blast is obviously better than that of using the 75% tricyclazole powder only or 75% trifloxystrobin.tebuconazole water dispersible granules only, thus the influence of spike neck blast on the rice is avoided or reduced, and the rice yield is increased. The rice is subjected to selenium enrichment treatment by use of the 1% sodium selenite solution, and the problem of insufficient selenium element in rice is solved; since the selenium element has the functions of preventing cancer and protecting liver, the rice value is increased.
Description
Technical field
The present invention relates to formula and the spray method thereof of the mixed synergist fertilizer of field bucket of a kind of prevention and treatment Rice blast disease, especially a kind of formula of medicine fertilizer of and selenium content deficiency sick for Rice blast and spraying.
Background technology
Rice blast is the normal property sent out, gas transmissibility Major Diseases on paddy rice, occurs to neat fringe blooming stage at paddy rice cut, and because weather condition are suitable, paddy rice is easy to occur panicle blast.Particularly a run of wet weather, sunshine is not enough, time rain when fine, sooner or later have cloud and mist and dew condition to descend, state of an illness expansion is rapidly.After catching an illness, form at first water stain shape chlorisis scab, last blackening brown, panicle neck necrosis, the nutrient passage that plant is transported to fringe portion is blocked, thereby forms dead ears or flat grain, cause not plump paddy increase, thousand seed weight to reduce, the general underproduction 10% ~ 30%, even has no harvest when serious.In conjunction with the various factors of the sick generation harm of panicle blast, the sick control of panicle blast is except selecting disease-resistant variety, seed disinfection, reinforcement field liquid manure management on producing, and outside growth promotion stalwartness is disease-resistant, medicament prevention and treatment are major measure.
Selenium is a kind of non-metallic element, is the essential trace element of humans and animals, and the selenium of trace has anti-cancer and liver-protective effect.Selenium is the kill agent of cancer cells, can alleviate the toxic side effect of Radiotherapy chemotherapy, reduces the toxicity of cancer therapy drug to kidney, marrow and stomach, the slight illness of reduction of patient.Selenium can directly act on virus, suppresses virus copying in vivo, and can participate in the reparation of cell, prevents multiple virus disease.Selenium can neutralize or transform the material of free radical, anti-oxidant, thereby dispels the infringement of radical pair human body, has the effect delaying senility.Selenium has the effect identical with Regular Insulin, can not rely on Regular Insulin and take sugar part in control agent, can delay, alleviate, prevent the generation of diabetic complication.Selenium and contaminated food, accumulate the heavy metals such as lead in body, mercury, cadmium and have very strong avidity,, directly excrete in conjunction with forming selenium-metal-protein complex with it, play the effect of removing toxic substances and toxin expelling.
Summary of the invention
Technical problem to be solved by this invention is to provide the mixed synergist fertilizer of field bucket and the spraying method thereof of a kind of prevention and treatment Rice blast disease, utilizes the mixed synergist fertilizer of said bucket can significantly improve prevention and result for the treatment of and the rich selenium to paddy rice to Rice blast disease.
For solving the problems of the technologies described above, technical scheme of the present invention is:
The mixed synergist fertilizer of field bucket of prevention and treatment Rice blast disease, comprises 75% tricyclazole powder of 10g ~ 30g, the 75% oxime bacterium tebuconazole water dispersible granule of 5g ~ 20g, 1% sodium selenite solution of 0.5g ~ 1.5g and the water of 25kg ~ 35kg.
Best bucket mix ratio is: 75% tricyclazole powder of 20g, the 75% oxime bacterium tebuconazole water dispersible granule of 15g, 1% sodium selenite solution of 1g and the water of 30kg.
The bucket mixing method of the mixed synergist fertilizer of field bucket of a kind of prevention and treatment Rice blast disease, utilize the mixed synergist fertilizer of field bucket of above-mentioned a kind of prevention and treatment Rice blast disease, comprise the steps: first to prepare the water of 1kg, then the mixing solutions of 1% sodium selenite solution of the 75% oxime bacterium tebuconazole water dispersible granule of 75% tricyclazole powder of 10g ~ 30g, 5 ~ 20g and 0.5g ~ 1.5g is placed in to water, the water that adds again 24kg ~ 34kg after stirring stirs.
Preferably first the 75% oxime bacterium tebuconazole water dispersible granule of 75% tricyclazole powder of 10g ~ 30g, 5g ~ 20g is carried out to abundant mixed dissolution in 1kg water, then 1% sodium selenite solution of 0.5g ~ 1.5g is uniformly mixed with it, the water that adds again 24kg ~ 34kg after stirring stirs again.
A spraying method for the mixed synergist fertilizer of field bucket of prevention and treatment Rice blast disease, utilizes a kind of mixed synergist fertilizer of field bucket that prevents and treat Rice blast disease, comprises the steps:
Step 1, initial stage control, by the medicine fertilizer of prevention and treatment Rice blast disease before paddy rice cut 3 ~ 5 days, adopts the mode of spraying to spray in paddy rice middle and upper part, and the time that sprays be controlled at 9 of fine days before or after 16 of fine days;
Step 2, later stage control, when all neat fringe of paddy rice, adopts the mode of spraying to spray on paddy rice the medicine fertilizer of prevention and treatment Rice blast disease, and the time that sprays be controlled at 9 of fine days before or after 16 of fine days.
The invention has the advantages that: by adopting the mixed synergist fertilizer of above-mentioned field bucket, utilize the composite panicle blast disease for paddy rice of 75% tricyclazole powder and 75% oxime bacterium tebuconazole water dispersible granule prevent and treat, its prevention and the sick successful for the treatment of panicle blast are better than single 75% tricyclazole powder or single 75% oxime bacterium tebuconazole water dispersible granule, the impact that makes paddy rice not be subject to or alleviate panicle blast disease, thus the output of paddy rice improved.Utilize 1% sodium selenite solution to carry out rich selenium processing to paddy rice, thereby make up the problem of selenium element deficiency in paddy rice, because selenium element has anti-cancer and liver-protective function, thereby improve the value of rice.
Embodiment
The mixed synergist fertilizer of field bucket of a kind of prevention of the present invention and treatment Rice blast disease, comprises 75% tricyclazole powder of 10g ~ 30g, the 75% oxime bacterium tebuconazole water dispersible granule of 5g ~ 20g, 1% sodium selenite solution of 0.5g ~ 1.5g and the water of 25kg ~ 35kg.For making drug effect reach best, its best bucket mix ratio is: 75% tricyclazole powder of 20g, the 75% oxime bacterium tebuconazole water dispersible granule of 15g, 1% sodium selenite solution of 1g and the water of 30kg.
