Requirements for soil acidity and alkalinity of the same crops
The sensitivity to sulfur dioxide damage varies between different crops and different varieties of the same crop. To make people aware of this, scientists use a certain amount of sulfur dioxide in the laboratory to smoke different crops. After a period of time, the damage to different crops is completely different and can be divided into three categories: sensitive crops, moderately sensitive crops, and resistant crops. For example, sensitive crops include barley, cotton, soybeans, spinach, carrots, and chili peppers; Medium resistant crops include wheat, beans, peanuts, cucumbers, rape and tomatoes; Resistant crops include rice, corn, and potatoes. Use a pH meter to measure the soil acidity and alkalinity, select suitable plants for planting, and make the harvest more objective.
The pH meter, abbreviated as pH meter, consists of two parts: an electrode and an ammeter. It is a commonly used instrument and equipment, consisting of three parts: a reference electrode, a glass electrode, and an ammeter. Widely used in industries, agriculture, scientific research, environmental protection, and other fields.
A pH meter is a commonly used instrument and equipment, also known as a pH meter. Mainly used for precise measurement of the pH value of liquid media, coupled with corresponding ion selective electrodes, the MV value of ion electrode potential can also be measured. CT series pH meters are widely used in industries, agriculture, scientific research, environmental protection, and other fields. This instrument is also an essential inspection equipment for QS and HACCP certification in food and drinking water plants. A pH meter is an instrument used to measure the pH value of a solution. The main body of the acidity meter is a precision potentiometer. When measuring, the composite electrode is inserted into the measured solution, and different electromotive forces are generated due to the different acidity (hydrogen ion concentration) of the measured solution. It is amplified by a DC amplifier, and finally the pH value of the measured solution is indicated by a reading indicator (voltmeter). The acidity meter can be used within the pH range of 0-14.
