After the beginning of spring, with the temperature rising slowly, the evaporation of soil moisture increases in the wheat field, which becomes the main way to consume water in wheat fields. At present, most of the wheat areas have not yet returned to green or are returning to green. The spring breeze will cause dry soil thickening and recurring low temperatures to become the biggest threat to wheat seedlings turning green. In order to ensure the return of young and healthy young crops, the management of wheat fields should be based on the goal of raising the temperature of the crops, and fully utilize the pressure cultivation system. At present, barley is generally the only measure to inhibit the development of dry soil, ensure soil moisture, and protect drought and seedlings. The wheat field cracking can break up the soil, reduce the cracks, compact the surface dry soil, reduce the evaporation of soil moisture, and prevent the emergence of wilting of wheat seedlings. If repression is not adopted, after the dry soil layer is continuously thickened by more than 8 cm, it will be more difficult to re-inject “life-saving water†at that time, and the effect will be even greater. Experts believe that from a technical perspective, the early spring suppression will benefit young wheat seedlings and return them Compacting the topsoil, flattening the soil surface, crushing the soil, reducing the large pores and preventing air leakage. Thinned dry soil layers. For example: In the general loam, there is 5 cm of dry soil on the land that is not repressed, and only 2 cm of dried soil on the repressed land. Without repressing the deep water vapor, repression can be used to connect the soil capillary, and the water vapor can be used to lift the earth, which can increase the soil moisture of the plough layer by about 1% to 3%. Repression can also increase the thermal conductivity of the soil, which is conducive to the rise of the earth's gas, warming and warming, and promoting root growth and timely return to green. At present, it is the critical period of wheat field repression. It should be noted that the time of repression is to warm up the weather (the maximum temperature exceeds 3°C), and before and after noon, the seedlings will thaw and become soft, and the ground surface will thawed and become crisp. Town pressure According to the soil condition, adjust the weight and speed of the repressor. For example, the sand field squat requires more pressure and heavy pressure, so as to increase the effectiveness of the smashing. The sticky soil cannot be repressed when the soil is sufficient to prevent the soil from compacting. Mechanized repression of wheat fields, farmers save time and effort It is understood that the provinces of Hebei, Shandong, Henan and other provinces had a good basis for autumn crops last year, with good emergence and growth, and the current wheat production has entered the key period of spring management. On the basis of the analysis of the situation of the situation of the crops, various types of wheat fields were promptly pressed. Measures to maintain soil moisture, increase surface temperature, and take the initiative for the future management of wheat fields. Some of them proposed that cultivators should be widely used for the purpose of increasing the temperature and protecting the soil, removing the compaction, improving soil permeability, promoting root growth, and eliminating weeds. In particular, Wangmiao wheat fields require deep cultivators, weak seedlings, wheat fields, shallow cultivators, large populations before the winter, wheat fields that continue to prosper after spring, early root cropping, deep cultivator root cutting, or repression; in short, the key to wheat field management. Technology is in place. Tiandy network recorders are tailored to fit different applications. Ultra Series recorders offer the best performance and highest quality. Pro Series devices are perfect for mid-large size businesses and projects which require a balance between performance and budget. Lite Series recorders are designed for optimum cost performance with strict Dahua quality standards.
Tiandy network recorders are equipped with various video channel capacities and physical sizes to cater to various use cases. Up to 256CH/unit with 4U size is suitable for applications with high recording requirements but without additional IP storage to on save costs, such as in schools, casino, building complexes, etc. 4CH/unit small box recorders are typically used in applications at home or small businesses like retail shops.
