Workers engaged in agricultural production have heard such a saying, that is, "a crop of flowers, relying on fertilizer to become a home", adding fertilizer, supplementing the lack of soil nutrients, meeting the nutritional needs of crops, increasing yield and quality of crops It has important significance. However, in traditional agricultural production, there are widespread problems such as low fertilizer utilization rate. At this stage, it is necessary to use professional instruments such as soil measuring instruments and advanced science and technology to improve the utilization rate of chemical fertilizers, protect land, and increase crop yield. For a long time, there have been many contradictions between agricultural environmental protection and agricultural production increase. However, these contradictions are not unresolvable. They only need to follow the laws of development, so that agricultural environmental protection and agricultural production can be realized simultaneously. Taking chemical fertilizer application as an example, excessive application of chemical fertilizers will cause problems such as soil and water pollution, and will also cause quality problems such as soil compaction and soil acidification. The soil tester is used to test the soil, and the soil conditions are fully understood. To achieve on-demand supply and precise fertilization, we can avoid problems such as excessive fertilization, which can protect the land on which we depend, and fully exert the fertility of fertilizers and improve the yield and quality of crops. Increasing the utilization rate of chemical fertilizers is equivalent to reducing the application rate of chemical fertilizers and reducing the cost, which is of great significance for farmers to increase production and increase income. Moreover, with the development of green agriculture, it is also necessary to use resources more efficiently, gradually reduce the amount of fertilizer applied, improve the quality of cultivated land, create efficient agricultural production fields, and lay a solid foundation for the development of green agriculture. In terms of improving the quality of cultivated land, professional soil instruments such as soil measuring instruments have played an important role, promoting the promotion and application of soil testing and formula fertilization technology, which not only reduces the cost of agricultural production, but also increases the economic income of farmers, and has obtained obvious Economic, social and ecological benefits have important practical and far-reaching significance for promoting the sustainable and stable growth of China's agriculture.
Construction Hoist (also called Building Hoist, Passenger Hoist, Construction Material Hoist, Construction Passenger Hoist) are an efficient and safe means of transporting people and materials on construction site. They help increase productivity and safety, thereby saving time and money.
Construction hoist is vertical transport machinery driving by pinion and rack, mainly used on construction site for transportation of personal and materials. As a permanent or sub-permanent external elevator, it also applies to store house, dock, high tower, high chimney, etc. There are single cage and double cages hoist. According to the need gets rid of one cage of double cages the hoist will be changed to single cage hoist. SC construction hoist is equipped with reliable electrical and mechanical safety device. It is efficient and safety vertical transporting equipment.
