美国朗布他仪器公司(LI—CORLTD)是一家专业性的仪器公司,这家公司生产的LI—700型和LI—1600型气孔计是用来测定植物由于蒸腾作用而发生的叶面气孔扩散阻力的变化,从而可以了解植物叶而气孔的开闭状况,这对于研究植物的光合作用;水分和养分的利用都是十分必要的。该仪器广泛适用于农业科学和环境科学的各个领域。它具有体积小,重量轻,携带方便,操作简单,测试迅速可靠等优点。最适合于田间或实验室使用。由于目前我国还不能生产气孔计,因此以往在测定植物叶面气孔开闭状况时,
The LI-CORLTD is a specialized instrumentation company that manufactures LI-700 and LI-1600 stomata for the measurement of leaf stomatal proliferation in plants due to transpiration Changes in resistance, which can understand the opening and closing of plant leaves and stomatal conditions, which for the study of plant photosynthesis; the use of moisture and nutrients are very necessary. The instrument is widely used in various fields of agricultural science and environmental science. It has small size, light weight, easy to carry, easy to operate, test quickly and reliably. Most suitable for field or laboratory use. Because at present our country can not produce the stomatometer, so in the past in the determination of plant leaf stomatal opening and closing conditions,
