1. Wheat: Wheat fields with small populations, weak growing fields, wheat fields in the sandy areas, and wheat fields with deferred fertilizers must be watered after returning to the green stage. Simultaneously, 20-30 kg of ammonium bicarbonate or 5-10 kg of urea are buried in the mu. In normal wheat fields, topdressing with watering is postponed until the jointing period. In combination with watering, acre generally applies 50 kg of ammonium bicarbonate or 15 to 20 kg of urea. In late April and early May, after the wheat was harvested, 4 wheat urea was applied in combination with watering. The middle stage of the grouting was the spraying of 1 to 2% of urea and 0.3% of potassium dihydrogen phosphate or aspartame in the middle of May. Grams, add 30 to 40 kilograms of water.
2. Maize: Corn 5 to 7 leaf stage combined with cultivator and watering Phosphate fertilizer 25-30 kg, 10 kg potassium fertilizer, 8 kg urea or 30 kg ammonium bicarbonate. For wheat fields covered with straw, it is necessary to increase ammonium bicarbonate by 7.5 to 15 kilograms and superphosphate by 10 to 20 kilograms. The big bell mouth buried 70 kg of ammonium bicarbonate or 25 kg of corn formula fertilizer. After the tasseling of corn, the attacking grain fertilizer was applied before flowering and pollination, and 3 to 5 kg of urea was topdressed with watering.
3. Soybean: Soybean is a crop that requires more nitrogen fertilizer. Applying a nitrogen fertilizer at the early flowering stage can reduce the rate of flowering and fruit drop, prolong plant life, increase grain weight, and increase yield. Generally, 8-12 kilograms of urea are applied per acre; After top dressing, the effect of increasing production is more obvious.
4. Peanuts: About 15 days after the emergence of peanuts, flower buds began to differentiate and nodule formation began. When two pairs of lateral branches appear in the plant, one-time nitrogen fertilizer should be applied in a timely manner. For each acre, the special fertilizer for peanuts is 20 to 25 kg or 8 kg of urea.
5. Cotton: The cotton seedlings in the early period are weak, mainly promoting, and the control is mainly in the middle and later periods. After budding cotton, it is necessary to apply steadily and skillfully. Generally, Mushi applies 10 to 15 kg of cotton fertilizer or 10 to 20 kg of diammonium phosphate and 10 to 20 kg of potassium sulfate. The cotton field with poor fertility, insufficient base fertilizer and weak cotton seedlings should be applied as early as possible, and should be applied more frequently. For cotton that has early or strong shoots and strong growth, it should be applied late, with little or no application.

As early as 2004, the total output value of China's video surveillance industry application market had reached 15.1 billion yuan, an increase of nearly 23% compared with 12.3 billion yuan in 2003, and growing at an annual rate of about 20%. According to the survey of the analysis institution, with the accelerating pace of life, the demand for family users' sense of security is gradually increasing, and the requirements for family monitoring and security are also increasingly mature.
As the video monitoring system plays an important role in protecting security and preventing crime, the growth of personal users' demand for family security will certainly drive the development of residential monitoring system. The demand for video surveillance from ordinary consumer households is becoming an emerging market for video surveillance applications, and is expected to show significant growth in the next few years.
