葉綠素是植物進(jìn)行光合作用的重要器官,而植物光合作用織造的氧氣,是我們?nèi)祟?lèi)呼吸的必需物質(zhì),因此檢測(cè)植物的葉綠素含量不但可以了解植物的生長(zhǎng),讓其生長(zhǎng)更加健康,同時(shí)對(duì)人類(lèi)和全部生物界都具有十分重要的含義,而葉綠素測(cè)定儀可以在不傷害植物的基礎(chǔ)上直接了解植物的葉綠素含量,了解植物的生長(zhǎng)狀況!
植物葉片中的葉綠素含量表示了植物本身的狀況,葉綠素的含量與植物的長(zhǎng)勢(shì)有直接的關(guān)系,長(zhǎng)勢(shì)好的植物,葉片中的葉綠素含量相對(duì)更高,而葉綠素的含量與葉片中氮的含量有很密切的關(guān)系,通過(guò)葉綠素測(cè)定儀檢測(cè)葉綠素可指導(dǎo)合理施加氮肥,提高氮的利用率,說(shuō)明植物真實(shí)的硝基需求量。
根據(jù)研究表明,氮素對(duì)作物生長(zhǎng)發(fā)育以及產(chǎn)量品質(zhì)都有顯著影響,作物缺氮時(shí),根系生產(chǎn)受到明顯抑制,而繁殖器官的形成和發(fā)育也受到限制,導(dǎo)致植株提前成熟,果實(shí)小而不充實(shí)。但是如果氮肥施用太多,會(huì)導(dǎo)致氮肥利用效率降低,同時(shí)造成地下水和地表水中硝態(tài)氮不斷積累,導(dǎo)致一系列環(huán)境問(wèn)題,形成水體富營(yíng)養(yǎng)化。因此合理施肥很重要,在保證產(chǎn)量的前提下,盡可能少施用氮肥以減少成本和環(huán)境污染,是現(xiàn)在一項(xiàng)重要的研究?jī)?nèi)容。
葉綠素測(cè)定儀可以立即測(cè)量植物葉片葉綠素的相對(duì)含量,葉綠素檢測(cè)通過(guò)測(cè)定spad值來(lái)顯示植物綠色程度,了解植物的生長(zhǎng)狀況的同時(shí)指導(dǎo)氮肥的合理使用,葉綠素測(cè)定儀測(cè)量時(shí)間快速,測(cè)量結(jié)果精準(zhǔn),儀器小巧方便便攜,可隨身攜帶到野外測(cè)量的,因此受到了越來(lái)越多的應(yīng)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!
