用叶绿素测定仪了解植物健康度
来源:绿博仪器 时间:2020-02-18 20:31:40 点击数:
叶绿素是植物进行光合作用的重要器官,而植物光合作用织造的氧气,是我们人类呼吸的必需物质,因此检测植物的叶绿素含量不但可以了解植物的生长,让其生长更加健康,同时对人类和全部生物界都具有十分重要的含义,而叶绿素测定仪可以在不伤害植物的基础上直接了解植物的叶绿素含量,了解植物的生长状况!
植物叶片中的叶绿素含量表示了植物本身的状况,叶绿素的含量与植物的长势有直接的关系,长势好的植物,叶片中的叶绿素含量相对更高,而叶绿素的含量与叶片中氮的含量有很密切的关系,通过叶绿素测定仪检测叶绿素可指导合理施加氮肥,提高氮的利用率,说明植物真实的硝基需求量。
根据研究表明,氮素对作物生长发育以及产量品质都有显著影响,作物缺氮时,根系生产受到明显抑制,而繁殖器官的形成和发育也受到限制,导致植株提前成熟,果实小而不充实。但是如果氮肥施用太多,会导致氮肥利用效率降低,同时造成地下水和地表水中硝态氮不断积累,导致一系列环境问题,形成水体富营养化。因此合理施肥很重要,在保证产量的前提下,尽可能少施用氮肥以减少成本和环境污染,是现在一项重要的研究内容。
 
叶绿素测定仪可以立即测量植物叶片叶绿素的相对含量,叶绿素检测通过测定spad值来显示植物绿色程度,了解植物的生长状况的同时指导氮肥的合理使用,叶绿素测定仪测量时间快速,测量结果精准,仪器小巧方便便携,可随身携带到野外测量的,因此受到了越来越多的应用!
Chlorophyll is an important organ for photosynthesis of plants, and the oxygen woven by photosynthesis of plants is an essential material for our breath. Therefore, the detection of chlorophyll content of plants can not only understand the growth of plants and make them grow more healthy, but also have a very important meaning for human beings and all biological communities. The chlorophyll meter can be used in the base of plants without damaging them On the basis of direct understanding of the chlorophyll content of plants, understand the growth of plants!
 
 
 
The content of chlorophyll in plant leaves indicates the condition of plant itself. The content of chlorophyll is directly related to the growth of plants. For plants with good growth, the content of chlorophyll in leaves is relatively higher, while the content of chlorophyll is closely related to the content of nitrogen in leaves. The detection of chlorophyll by chlorophyll analyzer can guide the rational application of nitrogen fertilizer and improve the utilization rate of nitrogen, It shows the real nitro demand of plants.
 
According to the study, nitrogen has a significant impact on crop growth and development, yield and quality. When the crop is short of nitrogen, the root system production is obviously inhibited, and the formation and development of reproductive organs are also limited, leading to early maturity of plants and small but not full fruits. However, if too much nitrogen is applied, it will reduce the efficiency of nitrogen utilization, and cause the accumulation of nitrate nitrogen in groundwater and surface water, resulting in a series of environmental problems and eutrophication of water body. Therefore, reasonable fertilization is very important. Under the premise of ensuring the yield, it is an important research content to apply as little nitrogen as possible to reduce the cost and environmental pollution.
 
 
 
Chlorophyll meter can measure the relative content of chlorophyll in the leaves of plants immediately. Chlorophyll meter can display the green degree of plants by measuring the SPAD value, understand the growth status of plants and guide the rational use of nitrogen fertilizer. Chlorophyll meter has fast measurement time, accurate measurement results, compact and portable instrument, which can be carried to the field for measurement. Therefore, it is more and more popular More apps!
