Summary of the invention
The object of the invention is for the deficiencies in the prior art, thus a kind of saving of work and time is provided, poisoning is little, control efficiency good, the application method of corn planting that can reduce costs.
In order to realize foregoing invention object, the technical solution adopted in the present invention is: a kind of application method of corn planting, and it comprises the following steps:
Step 1, corn resistance to lodging agent, bactericide and insecticide that selection property of medicine acid-base value is consistent;
Step 2, according to described corn resistance to lodging agent, described bactericide and described utilization of pesticides dosage, measure described corn resistance to lodging agent, described bactericide and described insecticide respectively, then, be watered, mix, obtain compound liquid medicine;
Step 3, when corn growth is to 8 ~ 12 leaves, described compound liquid medicine is adopted to spray corn.
Based on above-mentioned, in step 2, measure the insecticide of the corn resistance to lodging agent of 7.5 ~ 12 grams, the bactericide of 8 ~ 18 grams and 7.5 ~ 13.5 grams respectively, then, be watered 25 ~ 30 kilograms, mixing, obtain the compound liquid medicine that every mu of corn sprays consumption; Wherein, described corn resistance to lodging agent is one or both the combination in Jin get Le, Zhuang Feng An, and described bactericide is one or both the combination in triazolone, Tebuconazole, and described insecticide is carbosulfan.
Based on above-mentioned, in step 2, measure the insecticide of the corn resistance to lodging agent of 10 grams, the bactericide of 10 grams and 10 grams respectively, then, be watered 26 kilograms, mixing, obtain the compound liquid medicine that every mu of corn sprays consumption; Wherein, described corn resistance to lodging agent is Jin get Le, and described bactericide is triazolone, and described insecticide is carbosulfan.
Based on above-mentioned, in step 2, measure the insecticide of the corn resistance to lodging agent of 10.5 grams, the bactericide of 15 grams and 11.5 grams respectively, then, be watered 28 kilograms, mixing, obtain the compound liquid medicine that every mu of corn sprays consumption; Wherein, described corn resistance to lodging agent is Jin get Le, and described bactericide is Tebuconazole, and described insecticide is carbosulfan.
Hinge structure of the present invention has outstanding substantive distinguishing features and marked improvement, and specifically, the application method of this corn planting has following advantage:
1, science selects corn resistance to lodging agent, bactericide, insecticide, change single Pesticide use into compound use, and select applicable spraying time point, once spray, can effectively improve corn capacity for the resistance to lodging, can effective control of maize Diseases at Medium-late Growth, as Ustilago maydis, brown spot, stem rot and MRDV, can the effectively insect pest such as control of maize snout moth's larva, plant hopper.
2, by the method, can effective control of maize damage by disease and insect, reduce corn phytotoxicity, reduce drug risk, reduce the impact on environment, reduce the injury to operating personnel, in addition, by the method, also reduce drug cost and cost of labor.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
embodiment 1
An application method for corn planting, it comprises the following steps:
Step 1, corn resistance to lodging agent, bactericide and insecticide that selection property of medicine acid-base value is consistent; Described corn resistance to lodging agent is in corn planting, use more, safer, the anti-fall effect of use good vinyl corn resistance to lodging agent, as Jin get Le, beautiful gold, Zhuang Feng An etc., the main component of this corn resistance to lodging agent should be and corn stem foot can be suppressed to tie growing plants growth regulator; Described bactericide must effective control of maize gall smut and have certain preventive effect to maize brown spot, stem rot; Described insecticide effectively must kill corn borer larvae or worm's ovum also can effectively prevent and treat plant hopper insect.
Step 2, according to described corn resistance to lodging agent, described bactericide and described utilization of pesticides dosage, measure the insecticide of the corn resistance to lodging agent of 7.5 grams, the bactericide of 8 grams and 7.5 grams respectively, then, be watered 25 kilograms, mixing, obtains the compound liquid medicine that every mu of corn sprays consumption; Wherein, described corn resistance to lodging agent is the golden combination obtaining happy Zhuang Feng An, and described bactericide is the combination of triazolone and Tebuconazole, and described insecticide is carbosulfan.
Step 3, when corn growth is to 8 ~ 12 leaves, described compound liquid medicine is adopted once to spray corn.
Jin get Le, beautiful gold, Zhuang Feng An be all extensive use, resistance to lodging agent for crops such as corns, belongs to known technology; Triazolone, Tebuconazole and carbosulfan are all the medicines of extensive use, belong to known technology.
