Solid wood veneer as the main raw material, through high-frequency pressing and chairs made of different shapes. Bentwood chairs seat curved wooden multilayer board selected environmental pressing at high frequency, double-sided high-quality bendable fire board; election steel chair legs, powder coated or plated trim. Currently on the market 75% of bentwood chairs are curved wood and metal combination, modeling relatively simple, stylish. High seat bentwood chairs is very particular about, usually should be maintained at between 420-440mm, and bentwood chairs in to the desktop height should be maintained at between 280-320mm.

In China's planting industry, there have been problems such as unreasonable increases in fertilizer, abuse of inorganic fertilizers, and little or no organic fertilizers. This has led to a serious decline in the production capacity of cultivated land on which we depend. Through investigation, it has been found that the organic matter content in most of the arable land in China is already below the warning line, a large area of ​​the land has been severely compacted, and the soil fertility has turned red. Therefore, in order to improve the soil properties of current arable land, increase soil fertility, and increase crop yield, it is necessary to use a soil nutrient rapid tester to know scientific application of chemical fertilizers, to guide the application of organic fertilizers, to improve soil fertility, and to improve the soil environment for human survival. .
Therefore, it can also be said that the design background of the soil nutrient rapid tester is to improve the increasingly serious soil problems and use scientific and technical means to carry out measurement work, so that through the measurement data, combined with the local natural conditions and economic conditions, local conditions can be established. A practical plan is to gradually improve soil production and environmental conditions by gradually implementing soil improvement plans.
At the same time, the unscientific abuse and indiscriminate use of agricultural fertilizer not only caused serious problems of soil deterioration, but also resulted in low fertilizer utilization, unbalanced nutrients, and increased agricultural production costs, which in turn affected the quality and yield of agricultural products. Sustainable development of agriculture. Under this background, using the soil nutrient rapid tester to conduct scientific guidance can effectively solve the serious impact of blind fertilization and excessive fertilization on agricultural production and the environment, and improve the quality and efficiency of agricultural cultivation for the sustainable development of agriculture in China. Development creates favorable conditions.
We know that crop growth requires nutrients, light, moisture, etc., and nutrients as far as crops are like food for humans, so the growth of plants requires multiple nutrients. Soil is an important matrix for crops to absorb nutrients, so the nutrient content in the soil will directly affect the growth of crops. So in recent years, soil nutrient rapid tester is widely used in the determination of soil nutrient content.
