1. Strive to drain the accumulated water. In the flooded field, we will organize the human and material resources to drain the water to minimize the flooding time of crops. When the water is withdrawn, the floating objects are removed along with the water to reduce plant crushing and seedling rot, and prevent mud and sand pressure from damaging the plant. For uninundated fields, timely dig trenches, gutters, and waist ditches to ensure that the "three ditches" are unobstructed, so that open water can be drained and dark water can be filtered.
Second, seize the field management by category. One is to help seedlings and wash seedlings. For rice with short flooding time, wash seedlings in time. Lodging cotton, corn, soybeans, and vegetables should be promptly straightened to remove rotten leaves and diseased leaves. The second is to watch seedlings (trees) fertilize. After the submerged middle rice is out of the water, depending on the seedling condition, apply 3-5 kg ​​of urea and a small amount of potassium fertilizer per mu. Late rice seedlings are sprayed with a small amount of quick-acting chemical fertilizers and plant accelerators to accelerate the recovery of growth immediately after the water is returned to life, to promote early tillering of seedlings, and to cultivate strong tillers. Corn, cotton, soybeans, vegetables and other crops will be cultivated and loosened in a timely manner after rain and weather. According to the growth of seedlings, topdressing shall be supplemented, topdressing or ear fertilizer shall be applied to corn, topdressing shall be applied to cotton, and vegetables, fruits and tea shall be used in time. Spraying 0.2% potassium dihydrogen phosphate + 0.5% urea solution promotes the rapid recovery of vitality, and at the same time improves the soil cultivation. The third is due to seedling control. The photosynthetic ability of overcast and rainy crops is reduced, and the carbon and nitrogen metabolism disorders are easy to cause steepness. The vigorous growth of cotton leaves is sprayed with chlorophyll, the soybean leaves are sprayed with uniconazole, and the summer corn is sprayed with jade gold and other regulators to control prosperity. . Depending on the stubble and growth, late rice seedlings are regulated with paclobutrazol to prevent overage jointing seedlings.
3. Strengthen the prevention of diseases and insect pests. After floods and floods, we must do a good job of monitoring and forecasting pests and diseases, and do a good job of green prevention and control. Rice should focus on prevention and control of pests, sheath blight, rice blast and other diseases; corn should focus on prevention and control of pests such as sheath blight, ear rot, Spodoptera frugiperda, and corn borer; soybean should focus on soybean rolls Prevention and control of pests such as leaf borers and pod borers; cotton should focus on the prevention and control of stink bugs, cotton bollworm, Spodoptera litura, and Bemisia tabaci. Vegetables should focus on the prevention and control of pests, anthracnose, root rot, wilt, downy mildew, powdery mildew, Bemisia tabaci, soybean borer, diamondback moth, Spodoptera litura, and other pests. Fruits should be timely controlled for mites, aphids, gray mold, downy mildew, anthracnose and other diseases and pests; tea should focus on the prevention and control of anthracnose, tea caterpillars, small green leafhoppers, mites and other diseases and pests.
4. Scientific replanting and replanting. Late rice seedlings should be actively organized to adjust the seedlings in the places where the seedlings are more damaged. If the seedlings are insufficient, plough the whole field in time and use the early rice variety "Fanqiu" to broadcast live. If the leaves of the middle-paddy field after dewatering are indeed “drowned†and lose their function, but the root system is still alive, the seedlings can be cut and stored in time to regenerate rice; for the flooded paddy field, the season account should be calculated. "Early turn autumn" or water to drought. Soybeans, corn, peanuts, sesame, vegetables and other dry land crops that have been unacceptable due to disasters should be scientifically replanted and replanted in a timely manner according to local conditions. Corn, mung beans, sweet potatoes, buckwheat and other autumn cereals with short growth periods or vegetable varieties can be selected.
5. Collect in time. Organize manpower and machinery to promptly harvest mature early rice and spring corn, so as to mature one piece, harvest one piece, thresh and dry one piece, avoid stacking and cause germination and moldy, and ensure that the grains are returned to the warehouse. Pick up ripe peaches, grapes, summer oranges and other fruits, and harvest the flooded early rice, spring corn, vegetables, melons and fruits to minimize disaster losses.

Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
for example:
Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing key intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
