Early drainage For the corn that has suffered from the disaster, it is necessary to eliminate the accumulated water in the field, reduce the soil and air humidity, and promote the plant to resume growth. If the corn is afraid of cockroaches in the early stage, it should be drained in time, and the flooding time should not exceed half a day. In time, the soil will be affected by the impact of heavy water, strong winds and other factors, and it is necessary to timely carry out soil conservation and straightening according to the actual situation. Generally, there is no need to take remedial measures for the stems. When the weather improves, it will return to its erect state after a period of growth. The roots must be lifted immediately after the rain. When lifting, the stems should form a 30-50 degree angle with the ground. The corn roots are cultivated with soil and the feet are solid; the stems are generally difficult to restore growth, and the lighter plots are not easy to take rescue measures, so they can grow naturally. For the plots with severe stems, it is necessary to hurry to replant other Autumn crops to reduce losses. Early application of seedling fertilizer for fields that have been flooded for a long time and have serious waterlogging damage should be promptly applied to raise the seedling fertilizer, and urea can be applied in the large flare period. Spraying high-efficiency foliar fertilizer and root-promoting agent at the same time of fertilization, promote the transformation of seedlings, promote root development and promote recovery. For corn fields that are late in sowing, drought in seedling stage, and weak in growth, quick-acting nitrogen fertilizer can be added in time. Prevention and control of pests and diseases due to accumulation of water in the field, plant damage, soil water saturation, high air humidity, easy to lead to a variety of diseases. For corn fields where pests and diseases occur, symptomatic treatment is required. Spraying once every 10 days, a total of 2 to 3 times of drugs can be used to prevent pests in the field. At the same time, it is necessary to strengthen the field observation and timely remove the weeds, which can effectively prevent the virus from spreading and spreading, and early detection and timely removal of the diseased plants to bring out the field treatment. After cultivating and weeding rain, due to the large moisture content in the soil and the higher temperature, the weed growth rate is obviously accelerated. If the weeds are not cleared in time, it is easy to cause grass shortage. Therefore, after the heavy rain, the weeds should be sprayed with the stem-leaf-treated herbicide in a timely manner, so that we can carry out the cultivating and weeding to ensure the normal growth of the corn, and to promote the roots and weeds.

B: According to medical test items, clinical diagnostic reagents can be roughly divided into clinical chemical test reagents, immunology and
Serological testing reagents, hematological and cytogenetic testing reagents, microbiological testing reagents, body fluid excretion
Detection reagents, genetic diagnosis reagents, etc. Among them, the market share of clinical chemistry
The largest, close to 34%; followed by the immunology market, accounting for about 29%. Novel immunodiagnostic reagents and genetic diagnostic tests
The reagent was developed in the late 1980s, and it is the most common diagnostic reagent for all current diagnostic reagents, regardless of technology or market.
