Spraying 3-4 times 0.3%-0.4% (per 100 kg of water and 300-400 g of potassium dihydrogen phosphate) of 98% potassium dihydrogen phosphate in the fruit setting period and fruit growth period can increase the yield and improve the quality. . In addition, potassium dihydrogen phosphate can also be used as a fertilizer, dissolved in water, and watered under the grape plants, the dissolved concentration is 0.2%, and each plant is watered to about 500 ml.
After apple fruit bagging, 300-350 times of potassium dihydrogen phosphate is sprayed every 7-10 days to supplement the nutrients of the tree and enhance photosynthesis. The fruit can be supplemented with nutrients in time and the nutrients obtained are comprehensive and the effect is better. 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 prevention and control of pests and diseases.
After the peach peach fruit is produced, spraying 0.3%-0.4% potassium dihydrogen phosphate 3-4 times every 10 days can improve the yield and improve the quality.
After the pear pear is bagged, the phosphate fertilizer should be paid attention to in the top dressing. The potassium dihydrogen phosphate is sprayed once every 15 days, the concentration is 0.2%-0.4%, and it can be mixed with urea and borax to significantly improve the quality and yield.
At the initial flowering stage and full bloom stage of strawberry, 0.2% calcium sulfate and 0.05% manganese sulfate (1:1 volume) can improve the yield and fruit storage performance. Foliar application of 0.3% urea and 0.3%, 98% potassium dihydrogen phosphate 3-4 times before and after flowering can increase the fruit setting rate and 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 the fruiting, and can spray 0.2%-0.3% potassium dihydrogen phosphate 3-5 times on the foliar surface. It can also be applied at a concentration of 0.5%-0.7%, which can significantly improve the quality.
Bananas are planted in banana plants to survive, and the first new leaves are extracted. To the buds and flowers, potassium fertilizer must be applied every 15-20 days, 100-200 grams of potassium dihydrogen phosphate per plant per plant, applied around banana plants. Apply a small amount of mud from the ditch to cover the fertilizer, or apply it to the plant around 10-15 kg of water. In addition, it is necessary to spray 0.2%-0.3% of the potassium dihydrogen phosphate solution per 10-15 days of foliar surface to significantly increase the yield and quality.

Viral Transportation Medium Tube
Uses: used for the detection and sampling of influenza, hand, mouth, foot and other epidemic diseases
Inspection principle:
The combination of multiple antibiotics has broad-spectrum antibacterial and antifungal effects;
As a protein stabilizer, bovine serum albumin can increase the survival time and infection stability of the virus;
Buffers such as Hank's build a neutral environment, which helps to increase the survival time and infection stability of the virus;
Phenol red is an acid-base indicator, the discoloration area is 6.6 (yellow)~8.0 (red), and it is red at 7.2~7.4.
Steps:
1. According to the sampling requirements, use a sampling swab to collect samples.
