The soil parameter rapid tester reminds you: cold winter is approaching, beware of winter wheat freezing damage!
On October 29, local time, the World Meteorological Organization released a new version of the 'Global Seasonal Climate Update' and pointed out that this year’s 'La Niña phenomenon' is expected to be moderate to strong and will continue until next spring, which will affect many parts of the world. Climate: According to forecasts by experts in the field of meteorology, this year, my country may experience a cold winter that will happen once in 60 years. Wheat is one of the main food crops in my country, and it is also the main source of grain production and export of agricultural crops. It can be said that the output of wheat will affect everyone's daily life. Because this year may encounter special conditions of extreme cold weather, the growth of winter wheat will directly lead to next year’s output. In order for winter wheat to survive the winter safely, it is particularly necessary to use a soil parameter rapid measuring instrument to monitor soil parameters. The whole growth period of winter wheat can be divided into eight stages: emergence, tillering, overwintering, turning green, jointing, booting, filling and maturity. In addition to the necessary soil temperature and humidity, soil moisture, and soil pH. Among them, the tillering stage before the beginning of winter absorbs more nutrients, and during the overwintering period, although the plant grows slowly and absorbs less nutrients, this is the critical period for wheat growth differentiation and root growth, so no matter which stage soil nutrients are very important. The soil monitoring equipment that monitors soil temperature and humidity, soil pH, soil conductivity, etc., is either bulky or expensive, and is not suitable for routine use. The emergence of soil parameter rapid measuring instruments undoubtedly solved this problem. 1. The principle of the soil parameter rapid measuring instrument The soil parameter rapid measuring instrument is a sensor developed for rapid detection of soil components. The shape of the sensor adopts a hand-held design, which is convenient for users to carry. The probe adopts four needles. The probe design is made of stainless steel, which has good corrosion resistance and toughness. The soil parameter rapid measuring instrument can accurately detect and display various components in the soil in real time, such as: soil temperature and humidity, soil electrical conductivity, and soil nitrogen, phosphorus and potassium components; soil component indicators are important for crop growth Plays a very important role. The soil parameter rapid tester can accurately monitor various components in the soil. Through the detected data, the soil can be improved to achieve the purpose of monitoring the supply of plant nutrients, so that the crops are in an excellent living environment, thereby Increase production. 2. Precautions for the soil parameter rapid measuring instrument When using the soil parameter rapid measuring instrument, please pay attention to the following issues: 1. The probe must be in full contact with the soil and compacted. Ensure data accuracy. 2. The soil parameter rapid tester only tests soil and soil, and is not suitable for dry flour, small stones, organic wood chips, liquid particles, etc. 3. In order to improve the accuracy of the test results, please use the method of multi-point test to get the average value during the test. 4. When using, pay attention to the test point not to touch the stone, do not use too much force, otherwise it will easily damage the electrode. It is not suitable to be inserted in the soil for a long time, as it is easy to oxidize. 5. After the measurement, clean the soil particles on the probe surface with gauze in time to keep the probe dry. Third, the application scenarios of the soil parameter rapid measuring instrument In addition to the monitoring of winter wheat soil nutrients, this equipment is also widely used in agricultural production, soil research, greenhouse planting, orchard nursery, horticultural planting, and trees Planting, pot planting and other fields. As of the last time the La Niña phenomenon occurred in 2011, the production of agricultural products was disturbed by the extreme cold weather, which promoted a sharp rise in global food prices. In 2011-2012, global wheat production was reduced by 35 million tons. The Food Price Index of the Food and Agriculture Organization of the United Nations in February 2011 rose 37% from the end of 2009, reaching a record high. The intensity of this year’s 'La Niña phenomenon' has become moderate to strong. I am afraid that it will destroy global food production and supply and push up food prices. I also hope that all farmers will be more vigilant.
