Peanuts are grown by many people, and weeding is generally carried out on crops, and peanut cultivation is no exception. To weed the peanut fields, first of all, to understand the peanut weeds? There are many weeds in the field, and different weed herbicides are not the same. Let's take a look at the peanut field!
Overview of weed species in peanut fields
According to statistics, there are more than 60 kinds of weeds in peanut fields, belonging to about 24 families. It can be seen that there are many kinds of weeds. Common weeds include crabgrass, foxtail, goosegrass, dog stalk, white stalk, and stalk , purslane, thorny vegetables, fragrant aconite, etc., in addition to cockroaches, cocklebur, Solanum, mandala, ramie and sedge, etc., in addition to the above, there will be other weeds in some areas Appearance, weeds also have geographical distinctions, such as a weed, in the A area is more serious, but in the B area, relatively less, and vice versa, so everyone will be troubled in prevention.
At present, herbicides commonly used in peanut fields include quizalofop, flufenacetate, flufenazone, bentazon, acifluorfen, etc. According to some farmers' reactions, the single formulation now has a herbicidal effect. Can not meet the requirements, now basically use the compounding agent, the following small series will simply say a few compound formulas, to see what its advantages and disadvantages are.
Let me talk about binary compounding agents:
1. Quinoxaline + Ethyl fluoxetine: This formula is very common on the market. The main reason is that it is cheap and attracts many farmers. However, the shortcomings are also obvious. Weeds are easy to rebound, and for the field of fragrant aconite Basically invalid.
2, quizalofopin + flufenazone: this formula is currently used by many people, compared to the first formula, weeds are not easy to rebound, but the price will be more expensive, the same, for the fragrant aconite is basically invalid, in addition The formula should be taken care of when it is used, and it is easy to cause phytotoxicity. If it is not used, consult the dealer in detail.
Let's talk about the ternary compounding agent:
3, quizalofopin + bentazon + acifluorfen: This formula can be said to be cleared in the peanut field, broadleaf, fragrant aconite, sedge, etc., and there is no residue, but the disadvantages are very Obviously, the price is high. If you use this formula, pay attention to the cost accounting.
4, quizalofopin + bentazon + flufenazone: the formula, basically all the weeds (grass, broadleaf, fragrant aconite, sedge, etc.) in the peanut field are also eliminated, and the above formula is similar The shortcoming is also the high price. In addition, this formula can also be used for weeding in soybean fields. The weed effect on soybean fields is also good, but pay attention to the dosage and timing of medication.
Finally, the four yuan compounding agent:
5, quinquin + bentazon + acifluorfen + ethyl carboxy: This formula is also all the weeds in the peanut field, including fragrant aconite, but the price is relatively higher, suitable for some weed resistance The field is selected according to the specific circumstances.
Peanut seedling herbicide precautions
In addition to the five formulas mentioned above, there are some things to be aware of when using post-emergence herbicides in peanuts to achieve better herbicidal effects. There are four points:
1, do not re-spray and leak spray
When using peanut herbicides, heavy spray and leak spray will cause bad effects. Heavy spray may cause phytotoxicity. Leaking spray will result in poor weeding effect. Therefore, pay attention to it when you fight.
2, lyric issues
When the field is good, it is beneficial to the herbicide effect, and the herbicidal effect is relatively good. If the field is too dry, the ability of the weeds to absorb the herbicide liquid is reduced, and the herbicidal effect is normal. At this time, before the herbicide is used. Watering, or more water, the best.
3. Weather problems
Do not apply medicine when there is wind or rain, avoid the medicinal solution being washed away and cause poor efficacy. If there is wind, the liquid will drift and cause phytotoxicity to the next block. In fine weather in summer, it is recommended to fight after 16 pm. .
4, the concentration of liquid
Pay attention to the amount of herbicide, the concentration should not be too large, do not use the dose of 2 mu of land in an acre (in the actual process, some people do this), in this case, the grass is indeed dead, but the peanuts are also dead.

High Temperature Alloy is divided into three kinds of material: 760 ℃ high-temperature material, 1200℃ high temperature and 1500 ℃ high temperature materials, the tensile strength is 800 mpa. On other words,it refers to the metal material worked well in the condition of 760-1500 ℃ or above. It owns excellent high temperature strength, good resistance to oxidation and thermal corrosion resistance, good fatigue properties, fracture toughness and other comprehensive performance, this kind of material has became an irreplaceable key material in military and civilian gas turbine engine hot end components . According to the relevant theory, 760 ℃ high-temperature materials, according to the matrix elements,can be mainly divided into high temperature iron base alloy, nickel base superalloy and cobalt-based super alloy. According to the preparation process,it can be divided into deformation and high temperature alloy, casting high temperature alloy and powder metallurgy super alloy. According to the solid methods,it can be divided into solid solution strengthening, precipitation strengthening and oxide dispersion strengthened with fiber reinforced type, etc.
