Potassium dihydrogen phosphate is a high-efficiency compound fertilizer of phosphorus and potassium, which can promote the photosynthesis of crops, quickly supplement the effective nutrients of the soil, improve soil fertility, easy to absorb and utilize crops, enhance the ability of crops to resist cold, drought, diseases and pests, improve crop quality and other functions, with less dosage, high fertilizer efficiency, easy absorption, quick effect, easy to use, significant yield increase effect, etc., is a non-toxic, harmless, no residue green fertilizer, in recent years has been widely used in fruit production.
After the apple fruit is bagged, 300~350 times of potassium dihydrogen phosphate is sprayed every 7~10 days to supplement the nutrients of the tree, enhance photosynthesis, and make the fruit get nutrients in time. After the fruit is harvested, 0.5% urea and 0.3% potassium dihydrogen phosphate are sprayed every half month, which can be combined with the control of pests and diseases.
After the peach is fruited, spraying 0.3%~0.4% potassium dihydrogen phosphate 3~4 times every 10 days can improve the yield and improve the quality.
After pears are bagged, top dressing should focus on phosphorus and potassium fertilizers, potassium dihydrogen phosphate is sprayed every 15 days, with a concentration of 0.2% ~ 0.4%, and can be mixed with urea and borax spraying, which can significantly improve quality and yield.
Strawberry was sprayed with 0.2% calcium sulfate and 0.05% manganese sulfate (volume 1:1) at the early flowering and full flowering stage to improve the yield and fruit storage performance. Foliar spraying of 0.3% urea and 0.3% and 98% potassium dihydrogen phosphate for 3~4 times before and after flowering can improve fruit setting rate, improve fruit quality and increase single fruit weight.
Cherry cherries should pay attention to the application of phosphorus and potassium fertilizer in the later stage of fruiting, and foliar sprays of 0.2%~0.3% potassium dihydrogen phosphate can be applied 3~5 times. It can also be flushed, with a concentration of 0.5%~0.7%, which can significantly improve the quality.
Potassium dihydrogen phosphate has a great effect, and the scientific application effect is good, which is introduced here, and I hope it will be helpful to everyone.
