For this year's spring cropping production, “spring neck†short, low-lying and easy-to-fly plots may still produce stink bugs and other unfavorable conditions. According to the prediction of long-term agricultural meteorological conditions, crop planting structure and cultivation technology management, etc., in conjunction with 2015 Boli County crops The long-term trend forecast of biological disasters is proposed as follows: Upper Arm Blood Pressure Monitor Upper Arm Digital Blood Pressure Monitor,Best Upper Arm Blood Pressure Monitor,Blood Pressure Monitor For Large Arms,Wireless Upper Arm Blood Pressure Monitor Shenzhen Urion Technology Co., Ltd. , https://www.urionhealth.com
First, taking seed coating as the center, adopting various measures such as crop rotation, selection of disease-resistant varieties, and rational fertilization, comprehensive prevention and treatment of plant species and soil-borne pests and diseases
(1) Corn and soybean promotion seed coating agents prevent and control underground pests and soil-borne and species-borne diseases.
1. Heavily occurring plots and heavier incidences of corn head smut should be coated with a seed coating agent containing a tebuconazole component.
2. Soybeans should be planted in low-lying and easy-to-fly plots, and 2.5% of the seed coating agent (35% of Doughford) should be used to control soybean root rot; , Root rot occurs in severe plots, first of all to take rotation measures, chemical control of each crop using the 2.5% Shiloeh seed coating agent 100 ml of water plus 0.45 kg plus 72% Kelu 150 grams of seed coating. Severe occurrences of soybean cyst nematode disease should be covered with a seed coating agent with a high Carbofuran content.
(b) Underground pests of Ma Ling potato, tobacco, marigold, pepper, onion, garlic, sunflower and other crops, with 40% phoxim be dubbed 0.5% of toxic soil, 5-6 grams per hole (melons) , cabbage and other crops can not be used); can also be used 48% chlorpyrifos dubbed 0.5% of toxic soil, 5-6 grams per hole prevention and treatment (melons, tobacco, tomatoes and other crops can not be used). For phoxim and chlorpyrifos sensitive crops, the ground pests can be treated with 4.5% beta-cypermethrin plus 50 milliliters of fine soil and 30 kg of fine soil, dubbed toxic soil, with 5-10 grams per hole.
(3) When the crop borer of various crops is damaged, the seedbed spray can be sprayed with 4.5% beta-cypermethrin before planting 20-30 ml per 100 square meters. Or use 40% phoxim 800 times solution, spray the seedbed in conjunction with water (phosphorus can not be applied to melon, cabbage and other crops).
(D), rice seed treatment to prevent bastard disease should be selected Shi Bao Ke, Bai Ke, soaking seed seed treatment agent, not allowed to use evil seedling spirit, 901,901 II, 903 and other soaking agents. Using germination boxes and other facilities for high temperature soaking, 25% prochloraz EC 10 ml plus 50 kg of water, soaking time for pesticides is 24-30 hours, if the soaking time is too long will reduce the seed germination rate.
(5) Rice seedlings should be selected with good quality stimulants such as trobitamine, seedlings should be irrigated with water, and the temperature, moisture should be controlled, and the seedlings should be ventilated in time. Seedbed blight and bacterial wilt can be used for prevention or early treatment.
(6) When the vegetable in the greenhouse occurs larvae of Liriomyza sativae Blanchard, it shall be sprayed with 50% of the submerged 2000-3000 times liquid.
(seven) prevention of rice leaf miner: To promote the seedlings with medicine technology, that is, with 20% acetamiprid 10 grams of water 3-4 kg to spray 100 square meters before 1-2 days from the smashing bed. It is also possible to apply 48% chlorpyrifos 750-800 ml of fertiliser per hectare when rice is returned to green manure.
Second, the correct treatment of chemical weeding technology
(1) The soil is closed and weeding. Although it has the advantages of low cost and convenient use, its effect is greatly affected by soil moisture, temperature, organic matter and other factors, and the effect of herbicide is often poor. According to the actual situation, the farmers' friends applied the soil to close the herbicide or use the stem and leaf herbicide.
For corn, yucca edulis (lantana), xiao xiao (prickly peony), pickled leeks, curly stalks, and vicious weeds in soybean fields, we must first take deep plowing measures, and then use post-emergence shoots and leaves treatment. , do it early. Soybean field application period is suitable for the two true leaves of soybean to a compound leaf stage, the use of agents can be used fomesidin, clomazone and so on. Corn field application is suitable for the 3-5 leaf stage, choose nicotine, atrazine, nitrate, atrazine and so on.
(2) Hormone herbicides such as 2.4-D butyl ester are used for soil-enclosed herbicides, and sometimes show symptoms of corn and soybean injury after emergence. 72% of the 2.4-D butyl corn field soil closed dose should be reduced to 0.5 liters per hectare. German-American varieties and sand land are prohibited from use. Soybean field is prohibited.
(3) Rice seedlings in Honda should be made of high beds, and Dingkao pesticides in closed seedbeds are prone to phytotoxicity. Cyhalofoprin can be used for post-emergence shoot and leaf spray herbicides. Seedbeds are prohibited from using quincloracic agents for herbicides.
(4) The paddy field should promote soil closing and weed control technology before plugging in: After soaking in the paddy field, use 60% butachlor (Marshall) 1.5 litres or 12% Nongita 1.5 liters per hectare. Into, strive to spread the average. Must be drained after 3 days of application. Increasing the dosage and short interval time are not conducive to slow seedlings.
(E) After transplanting rice, weeds should be selected for the use of agents that have no effect on rice tillers: For example, Maret, Mefenacet, Sulfophos, Indole, etc., as far as possible without butachlor, the use of alachlor is prohibited. Herbicides such as acetochlor, dur, metsulfuron, dimethyl tetrachlorine and other ingredients.
(VI) Prevention of Sagittaria Mushrooms should be performed with deep plowing, deep plowing, deep application of phosphate fertilizers, and then use of drugs such as pyrazosulfuron-methyl, ethoxylated sulfosulfuron, etc.; , Penoxsulam, valprocarb and other agents; prevention and control of grasses promote the use of pyrazosulfuron, bensulfuron and other agents after the two application techniques.
Third, reasonable adjustments to avoid the occurrence of residual drug injury
(1) For corn fields, 40% atrazine is used for weed control. For each hectare of land with a commercial volume of more than 2 kg, the corn can be planted only with corn. After the last year, the active ingredient of nicosulfuron corn after weeding is 60 per hectare. The plot of land is still planted with corn and soybeans this year; in the previous year, it was impossible to grow rice with oxacillin (defensible) weeding and weeding; last year, sandy land could not be grown with mesotrione weeding; Pyroxypyr herbicides can not grow soybeans and garlic.
(b) In the previous year, the soybean field was treated with 25% fomesafen, with a dosage of 1.5 liters per loquat, and stumm of corn, sugar beet, etc. would occur. In the previous year, clomazone used soybeans with an active ingredient of more than 700 grams per hectare, and soybeans were still planted this year.
(3) In the last year, the land used for the reform of dry land in the water use of 50% quinclorac is more than 14 grams per mu. No crops such as beets, potatoes, vegetables, etc. can be grown within two years.
(4) Tobacco and potato fields are sirisulfuron for weed control. In the second year, crops such as sugar beet, rape, and flax cannot be grown.
Any field containing the above-mentioned pharmaceuticals cannot be used as a nursery soil. When the drought-improved water and water are changed to dry land, the long-lasting residual herbicides should be taken seriously.
Fourth, use low-toxic pesticides to protect ecological balance
It is forbidden to use highly poisonous, high-residue, “triple†types of pesticides such as formazan, methamidophos, 3911, carbofuran, pentachloronitrobenzene, etc.; the use of oxygenated dimethoate and formazan in paddy fields is prohibited. Phosphorus, pyrethroid insecticides, promote the use of new generation insecticides such as imidacloprid, acetamiprid, and cyromazine.
Fifth, seize the favorable opportunity in the spring and do a good job of farmland rodent control work
Take advantage of the favorable opportunities in spring farmland to eradicate rats, conduct organized large-scale anti-rodent activities in an organized manner, and publicize and promote the use of covert application techniques based on "poison bait stations" and the "cats" rodent control technology for raising seedlings. Farmers protect the consciousness of cats, snakes, and other natural enemies of the mouse, and give full play to the control of natural enemies on rats.
Farmland rodent control prohibits the use of tetramine, three-step downgrade and other high toxic rat drugs, and promotes the use of the second generation of anticoagulant rodenticides.
