Answer: The main reasons for strawberry fruit malformation are: less pollinating insects, artificial pollination can not keep up; temperature is too low or too high, is not conducive to the cracking, pollination, fertilization of anthers; improper spraying pesticides; poor fertility of varieties. Control measures: Select high-yielding varieties, increase the amount of bees in a timely manner, avoid application during the flowering period, and switch to smoked smoke. During the flowering period, the temperature and humidity should be controlled. The low temperature should not be lower than 10 °C, the high temperature should not be higher than 40 °C, and the soil water content should be controlled at about 70%.

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.
