#Chinese Romance##Potassium Dihydrogen Phosphate#Potassium Dihydrogen Phosphate is a highly efficient phosphorus and potassium fertilizer, which is widely used because of its remarkable fertilizer effect. However, if used incorrectly, it can have a negative impact on plants. This article will introduce the correct use of potassium dihydrogen phosphate, and it is recommended to store it so as not to find it when you use it.
In the scene of citrus fruit preservation, the use of potassium dihydrogen phosphate is 500~800 times. For the mean tree, it is recommended to use 600~800 times; For Wangshu, 500~600 times can be used. It should be noted that weak trees should not use potassium dihydrogen phosphate, but should use amino acids, alginic acid, high-nitrogen foliar fertilizers or urea. In addition, during the fruit-preserving period, the moderate tree needs to spray potassium dihydrogen phosphate once, while the wang tree needs to spray 1~2 times.
In the scene of controlling summer tips, the dilution factor of potassium dihydrogen phosphate is 400~500 times. For the Mean tree, 500x is recommended; For wangshu, 400~500 times can be used. It should be noted that the varieties that are easy to drop fruit need to be sprayed with paclobutrazole or flucolimide + potassium dihydrogen phosphate to control the summer tip, while the varieties that are easy to preserve the fruit and control the tip do not need to be sprayed.
The use of potassium dihydrogen phosphate is generally foliar spraying, and an appropriate amount of water should be added to make it a solution with a suitable concentration. The time of spraying should be chosen in the morning or afternoon, avoiding spraying in the middle of the day when the sun is strong. In addition, it is necessary to pay attention to the uniformity of spraying to avoid the situation of too high or too low local concentration.
When using potassium dihydrogen phosphate, the following points also need to be noted: first, potassium dihydrogen phosphate cannot be mixed with alkaline substances, otherwise it will produce precipitation and reduce fertilizer efficiency; Secondly, potassium dihydrogen phosphate cannot be stored for a long time, and it is generally necessary to prepare it for immediate use; Finally, potassium dihydrogen phosphate cannot be used in aquatic plants because fertilization of water can cause root rot. #Wolkan##Is the outbreak of bacterial anthrax in Russia harmful#
