In the cultivation of cherry orchards, the production of cherry fruit is changing from quantitative to qualitative. However, the traditional soil environment clearly no longer applies the current mode of production. In order to improve the quality of cherries, it is imperative to use soil nutrients to improve the soil environment.
Poor soil environment is the bottleneck that restricts the further development of cherry fruit industry. The cherry trees are most afraid of planting insects in the roots, so when selecting the soil, it is best to choose new soil, calcium soil, etc., but also to ensure adequate vision. Digging pits after planting is best to cover the new soil above, do not use too fertile soil, such as growing up and later fertilize, mainly farmyard manure. At present, many orchards at home and abroad have gradually adopted the soil nutrient analyzer to change the soil management model. Accurate and rapid determination of soil nutrients in a cherry orchard has played a very good role in improving soil water content in orchards, increasing yield, and improving quality.
The soil nutrient analyzer can determine the soil bulk density, soil moisture, soil pH, soil nutrient nitrogen fertilizer, and phosphorus deficiency in cherry orchards, and provide valid data for cherry planting. The management efficiency of the fertilizer and water in the cherry orchard is improved, and the quality of the cherry is also improved while ensuring the yield.
The brake disc is composed of steel plate, adhesive heat insulation layer and friction block. The steel plate is applied to resist rust. In the painting process, smt-4 furnace temperature tracker is used to detect the temperature distribution in the coating process to guarantee the quality. The heat insulation layer is composed of non-heat transfer materials for the purpose of heat insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to generate friction, so as to achieve the purpose of decelerating the brake. As a result of friction, the friction block will be worn gradually, generally speaking, the lower the cost of brake block wear faster.
Tower Crane Brake Disc is used for tower crane motors. To divide in function , there are hoisting brake disc, trolleying disc brake pad and slewing motor brake disc. Tower Crane Brake Disc is the easy wearing spare parts, therefore the quality of the Brake Disc is very important. BQ provides good quality Brake Disc, which is composed of steel plate, adhesive heat insulation layer and friction block. The steel plate is applied to resist rust.
