Using Ground Temperature Thermometers to Analyze the Causes of Unsmooth Grape Seeds
At present, with the rapid development of facility agriculture, there are many areas of grape cultivation that adopt greenhouse cultivation methods. For greenhouse grape cultivation, most growers know to pay attention to temperature changes in greenhouses, but many times ignore the changes in the ground temperature. In fact, the effect of ground temperature on the viticulture of the greenhouse is also very large, especially in the budding period of grape growth. If the ground temperature is too low, it will cause irregular sprouting of the grapes, which will affect the effect of viticulture, so in order to better carry out the greenhouse For the scientific cultivation of grapes, we can use geothermal thermometers to pay more attention to the changes in the temperature of greenhouses and take timely measures to regulate and control the environmental conditions required for grape growth.
In general, the most common cause of sprouting is that the fruit load was too high in the previous year and the tree vigor was overstretched; the downy mildew prevented the loss, the leaves fall prematurely; the long shoots were left with many buds, and the apical dominance was low; the ground temperature was low, the roots were not regained, and the roots were absorbed. Poor. It can be seen that the low ground temperature is also an important cause of the irregular budding of the grapes. Many times we use a thermometer to check the temperature in the greenhouse and find that the temperature is already high, continuing at more than 30 degrees, but this time using a ground temperature thermometer to determine, but found that the temperature is still very low. If the ground temperature does not reach 8-10 degrees and continues for a period of time, then the root system has not regained consciousness and the absorption of water and fertilizers does not come up, but the ground part has begun to sprout. This situation is the reason why we promoted the most common budding in early cultivation.
The greenhouse temperature and the ground temperature can be said to be two different concepts. It requires the use of different instruments for detection. The most commonly used temperature detection is the ground temperature thermometer. The use of ground temperature thermometers to regularly conduct greenhouse temperature testing can enhance the detection and management of ground temperature, avoid problems such as poor grape growth caused by low ground temperature, and low yields, providing an important scientific basis for greenhouse grape cultivation, and further improve the greenhouse cultivation Quality and output help growers increase production and income.
