Spray 98% of potassium dihydrogen phosphate in 0.3%-0.4% (100 kg of water and 300-400 g of monopotassium dihydrogen phosphate) for 3-4 times during fruit set and fruit growing period to increase yield and improve quality. . In addition, potassium dihydrogen phosphate can also be used as fertilization, dissolved in water, watered under grape plants, the concentration of dissolved 0.2%, each plant watered about 500 ml.
After bagging apple fruit, 300-350 times of potassium dihydrogen phosphate is sprayed every 7-10 days to supplement the nutrient of the tree body and enhance photosynthesis, so that the fruit can be provided with nutrients in a timely manner and the nutrients obtained can be comprehensive and the effect is better. After harvesting, 0.5% urea and 0.3% potassium dihydrogen phosphate are sprayed once every half month, which can be combined with pest control.
After the results of the peach fruit, spraying 0.3%-0.4% of potassium dihydrogen phosphate 3-4 times every 10 days can increase the yield and enhance the quality.
Pear pear bagging, top dressing should pay attention to phosphorus and potassium fertilizer, potassium dihydrogen phosphate spray once every 15 days, the concentration of 0.2% -0.4%, and can be mixed with urea, borax spray, can significantly improve the quality and yield.
Strawberry 0.2% calcium sulfate and 0.05% manganese sulfate (volume 1:1) were sprayed at the initial flowering stage and flowering stage to increase the yield and fruit storage performance. Spraying 0.3% urea and 0.3%, 98% potassium dihydrogen phosphate 3-4 times before and after flowering can increase fruit setting rate, improve fruit quality and increase fruit weight.
Cherry cherry should pay attention to the application of phosphorus and potassium fertilizer in the later stage of fruiting, and it can spray 0.2%-0.3% potassium dihydrogen phosphate 3-5 times. Can also be flushing, the concentration of 0.5% -0.7%, can significantly improve the quality.
Bananas are planted on banana plants and begin to take out the first new leaf until the buds bloom. Potassium must be applied every 15-20 days, each time 100-200 g of potassium dihydrogen phosphate is applied to each plant and applied around the banana plants. , The shovel can be covered with a small amount of mud to cover the fertilizer, or 10-15 kg of fresh water applied to the plants. In addition, a 0.2%-0.3% solution of 98% potassium dihydrogen phosphate must be sprayed on the leaves every 10-15 days, which can significantly increase the yield and quality.
