Actress is a common physiological obstacle in the growing period of vegetable seedlings. Its characteristics are: thin stems, long internodes, thin leaves, light green leaves, soft tissue, underdeveloped roots; slow seedlings after planting, low survival rate, late and abnormal flower bud differentiation, small number of flower buds, abnormal flowers and More weak flowers, easy to fall off, it is difficult to get precocious, high yield. Preventive measures 1 Prevent increased light and control seedbed temperature. When the seedlings grow congested, and time seedlings, seedlings; later seedlings, can increase the spacing, prevent excessive shade; as much as possible to increase light, even in cold weather, but also appropriate to open the cover, so that seedlings see the light; When the open air temperature is appropriate, all coverings are removed and the seedlings are fully exposed to light. The seedbed temperature must be strictly controlled according to the needs of the seedlings at various stages of growth and development. 2 The remedy is mainly to control watering, spray phosphorus, potash or use plant growth regulators to inhibit growth. According to the experiment, tomato seedlings sprayed 1 kilogram of 2000 PPM chlorprodene solution per square meter of bed surface when they tend to grow in length. After 10 days, the leaf color turned green and the stems became thick, and their stress resistance was also significantly enhanced. The Infrared Thermometer is designed for measuring the human body forehead temperature reference. It is very simple and convenient to use. Accurate temperature measurement in 1 second, no laser spot, avoid potential damage to eyes, no need to touch human skin, avoid cross infection, one-click temperature measurement, and check for flu. It is suitable for home users, hotels, libraries, large enterprises and institutions, and can also be used in hospitals, schools, customs, airports and other comprehensive places, and can also be provided to medical personnel for use in clinics.

The normal body temperature of the human body averages between 36 ~ 37 ℃), exceeding 37.1 ℃ means fever, 37.3_38 ℃ is low fever, and 38.1_40 ℃ is high fever. Life above 40 ° C is always dangerous.
1. Human body temperature measurement: accurate measurement of human body temperature, replacing traditional mercury thermometers. Women who want to have a child can use an infrared thermometer (frontal temperature gun) to monitor the basal body temperature at any time, record the body temperature during ovulation, and choose the right time to conceive, and can also measure the temperature to judge pregnancy.
Of course, the most important thing is to observe whether your body temperature is abnormal at any time, to avoid flu infection, and to prevent swine flu.
2. Skin temperature measurement: To measure the surface temperature of the human skin, for example, it can be used for amputation and re-implantation surgery.
3. Object temperature measurement: To measure the surface temperature of an object, for example, it can be used to measure the temperature of the surface of a tea cup.
4. Liquid temperature measurement: measure the temperature of the liquid, such as the temperature of the baby's bath water. When the baby takes a bath, measure the water temperature, and no longer worry about being cold or hot; you can also measure the water temperature of the milk bottle to facilitate the preparation of Baby's milk powder
5. Room temperature can be measured:
※Precautions:
1. Please read the instructions carefully before the measurement, and the forehead should be kept dry, and the hair should not cover the forehead (please carry out the measurement in the environment of 10 ℃ -40 ℃) to ensure the accuracy of the measurement.
2. The forehead temperature quickly measured by this product is for reference only, and should not be used as a basis for medical judgment. If you find abnormal body temperature, please use a medical thermometer for further measurement.
3. Please protect the sensing lens and clean it in time. If the change of the ambient temperature is too large, you need to place the measuring instrument in the environment to be measured for 20 minutes, wait for it to adapt to the ambient temperature, and then use it to measure more accurate values.
