Problems solved by technology

The sampling time of this method is longer, the sampling amount is less, and the sampling site is limited to the base of the stem; more importantly, due to the removal of the above-ground part, the transpiration force disappears, and the flow rate and component composition of the juice during sampling are relatively different from those of plants in a natural state. Large, can not reflect the real situation of the plant

Embodiment Construction

[0014] Pressure chamber (6) of the present invention is that wall and 2cm thick seamless steel plate are processed at the bottom by 2cm thick seamless steel pipe, and the diameter and height of pressure chamber (6) can be processed into 20-50cm according to the difference of measuring plant . The pressure chamber cover (9) is processed by a seamless flange with a thickness of 2cm. The sealing collar (8) is made of elastic material, wedge-shaped, and completely coincides with the middle hole of the pressure chamber cover (9), but the thickness is 3-5cm thicker than the pressure chamber cover (9), and the inner diameter can be made according to the different diameters of the samples. 10mm-24mm. The above-mentioned high-pressure gas cylinder (1), high-pressure gas cylinder switch (2), pressure gauge (3), air intake control valve (4), high-pressure connecting pipe (5), bolts (7), precision pressure gauge (10) , exhaust control valve (11) are all commercially available parts. Th...

Abstract

The invention provides a sampling device and method for the plant balance pressing juice, which is proper for the plant physiology, bionomy and agriculture study. So it is important in using water, fighting drought and breeding of crop. The plant juice sampling device is made up of the high-pressure tank, the tank switch, the manometer, the air inlet controlling valve, the high pressure connecting pipe, the pressure room, the room cover, the sealing collar, the precise manometer, the exhaust controlling valve and vent. In close condition, it give the pressure on the balance pressure at sampling part and keep it by the gas-liquid balancing technology to extract the juice of leaf, tress, stalk and root for test. The merits of it is that the sample is near the real condition, the time is short, the quantity is much, the sampling part is not limited; the precision and quantity are all meet the advance analysis request; also it can detect the water potential of sampling organic.

Description

(1) Technical field [0001] The invention relates to a plant juice sampling instrument and a sampling method. It is suitable for plant physiology, ecology, and agronomy research, and has extremely important application value in the rational water use of crops and drought-resistant breeding. (2) Background technology [0002] Plant juice contains many substances such as water, mineral elements, sugar, amino acids, hormones, etc., and its quantity, composition and content are important indicators of the metabolic vitality of plants. The amount of sap is affected by external factors such as soil moisture, temperature, and ventilation conditions, and is also related to internal factors such as plant growth and root vitality. Sampling and determination of plant juice are helpful to study the water use of plants and the relationship between plants and the environment, and play an important role in guiding plants, especially crops, to use water rationally and resist drought.
