How to remedy the phytotoxicity of herbicides?

Detoxification: 1. When the drug is used the most, the field irrigation water should be drained immediately, washed with new water several times, and neutralized with acidic herbicides such as lime; 2. If there are many herbicides on the plant, it can be sprayed with mechanical water. Wash, reduce the poison attached to the leaves; 3. When the local phytotoxicity occurs in the field, first rinse the water, cultivate, then replenish the seedlings, and then add the quick-acting fertilizer; 4. If the field is poisoned seriously, the plot should be exposed to the sun and rinsed. After deep turning, no more effects will be planted, otherwise it will be re-irrigated. Or plant a small amount of sensitive crops and observe for 10-15 days. Linyi Fertilizer Network Copyright

Strengthen field management: when the phytotoxicity is light, timely topping or removing the affected part, adding quick-acting fertilizer and rational irrigation; when it is serious, ploughing the land, replanting or replanting; when the grass is found in the grass, it can be more The fertilizer and organic fertilizer can be applied, and it can also be sprayed with dilute ammonia or 1% lime water, and sprayed with hormone pesticides.

Application of plant growth regulator: Spray 4% gibberellin EC to promote crop growth. Linyi Fertilizer Network Copyright

Application safety agent: Safety agent, also known as antidote, can protect crops and detoxify various herbicides. If the seeds are coated with activated carbon or roots, stalks, or evenly spread on the soil surface, simazine can be prevented from causing phytotoxicity to soybeans and wheat; guanidine phthalic anhydride can prevent sulfides such as acetaminophen against corn.

Steel Reducer,a kind of industrial pipe fittings,  used to connect two different diameter pipes . According to different shapes, divided into concentric reducers and eccentric reducers. Materials include stainless steel, alloy steel, carbon steel. Forming process commonly used to suppress necking, expanding suppress or necking plus expanding repression,some specifications  may also be stamping.
1. suppress necking / expanding suppress forming
suppress necking forming process is to put  pipe into the forming molds,suppress necking another pipe end to smaller size . Depending on the another end size changing, divided into one time  press forming or more  times press forming.
2. Stamping  forming
In addition to using steel pipe as raw material to produce reducers, we can use stamping forming to make plates to reducers . the stamping molds are designed according to reducers inside ourside diameters, the molds makes steel plate to stamping ,cutting , stretch forming.
