1. The reason for this phenomenon is not the imbalance of nitrogen, phosphorus, and potassium? If it is applied to the base fertilizer or the topdressing is not in line with the requirements of the ratio of nitrogen, phosphorus and potassium required for tomato production (3.5:0.9:3.89), if the nitrogen fertilizer is too much, the plants will be prone to grow mad, and if the potassium is too little, the fruit will not be easy to expand. . If this is the case, it is advisable to immediately apply the "Jin Bilai" brand fruit that contains 55% (15:5:35) of nitrogen, phosphorus and potassium, and trace elements rich in boron, copper, iron, molybdenum, zinc, and magnesium. Potassium Po can be used for quick and effective fertilization, 5 kg/mu, or 55% nitrogen, phosphorus and potassium (10:10:35) and sulfur, boron, magnesium, copper, iron, manganese, zinc, calcium, etc. Trace elements of "Eurasian America" ​​brand fertilization, the effect is certainly satisfactory.
2. Immediately spray the effective components extracted from marine organisms, add a variety of trace elements and plant cell activators, starters, and regulate the balance between plant reproductive growth and vegetative growth, so that the crop root system is developed, internode shortening, Stem thick green leaves, not long and not crazy, "rain forest" brand special high-efficiency dwarfing 500-1000 times liquid, the effect is obvious.
3. If the pollinating agent is 2,4-D water or tablets, it is recommended to use the special and effective fruit set for the tomato, which has a high rate of fruit set, no deformity, and obvious swelling.
4. Spray 24% swelling fruit capsules with obvious expansion, rich in nitrogen, phosphorus, potassium, humic acid, pectin, biotin, DA-6 and various trace elements. 15 kilograms, or spray a 10% expansive high efficiency new type of fruit expander 750 times, obvious effect of swelling, better effect.
The performance of the Baby Monitor Security Camera
The performance of the baby monitor is reflected by its built-in parameters and function combination. The following shows some properties that a high-quality and applicable baby monitor should have. The requirements for baby monitors in this part apply to all audio/video, digital/analog home baby monitors and wireless baby monitors, and are not changed due to the combination mode of the monitoring end and the control end.
The size shall be as small as possible: the small baby monitor (monitoring end and control end) is more convenient to install and carry in the family.Low power display: the baby monitor, especially the monitoring terminal, must work continuously for a long time. Once the product is low in power, it cannot remind parents to charge it in time. When the power continues to be consumed until it is exhausted, the control terminal will be unable to continue to receive any signal.
Voice trigger prompt: Voice trigger means that once the monitoring terminal detects the noise caused by the abnormal behavior of infants or children, it will be displayed at the control terminal through the noise prompt lamp.
The transmission signal frequency can be adjusted: the monitoring end of the baby monitor provides audio and video digital signals to the control end by transmitting wireless signals. If the transmission frequency of the monitoring end is not selected properly, it will produce electromagnetic interference with other household appliances, digital equipment, etc., which will affect the normal use of the product. Therefore, it is necessary to select a baby monitor that allows users to adjust the frequency of the transmitted signal at the monitoring end.
Adjustable volume: a friendly baby monitor will provide a volume selection knob or button at the control end. When parents are in an environment with loud background sound, they can hear the activity sound of babies and children by turning up the volume; When it is late at night or in a quiet environment, the low volume will not affect the normal rest of the people around you when you are answering normally.
VOX function: VOX is the abbreviation of sound activation start. The monitor with VOX function is in standby mode under normal conditions, and the screen and horn stop working, thus reducing the energy consumption of the product; Once it is detected that the monitored object has an abnormal sound exceeding the set standard, it will immediately flash its alarm lamp at the control terminal or directly light up the screen, and simultaneously play the audio and video information sent by the monitoring terminal.
Digital signals and analog signals: baby monitors using digital signals, such as Baohushen baby monitors, will have better transmission efficiency and provide users with clearer sound and picture quality; Moreover, digital signals can be encrypted to prevent being intercepted and interpreted by other receivers, effectively protecting users' family privacy; The electromagnetic signal interference of digital signal will be lower than that of analog signal, so as not to affect the normal work of other household appliances and equipment.
Monitoring end extension: The baby monitor with a friendly user experience should allow users to use one control end to manage the activities of several monitoring ends at the same time, especially in some families with multiple children. This good scalability not only reduces the trouble of carrying multiple control ends at the same time, but also reduces the objective additional expenses for these families.
Temperature display: some products will have the function of realizing the current indoor temperature, and even can set a critical value. Once the room temperature exceeds or falls below the critical value, an alarm signal will be sent. This is a very considerate function for temperature sensitive newborn children or sick children.
Intercom function: The high-end baby monitor allows parents to have a direct conversation with the baby (child) at one end of the monitoring end through the control end, so that children who are alone can provide psychological comfort. If children have any temporary needs or words, they can be known without bothering the guardian to run to the child.
Signal range: theoretically, the signal sent by the monitoring terminal can be received by the remote control terminal, which is more convenient for users to use the baby monitor flexibly. Now more and more families live in large family rooms, even multi-storey villas, and the baby monitor with strong signal receiving ability provides these families with a more convenient way of use. Parents no longer need to set the room beside the children in order to see and hear their children's every move. They can even take the control terminal to go out for a short walk!
Power supply mode: The baby monitor with built-in battery can automatically switch to the battery power supply mode when the external AC power supply is suddenly stopped, so that the user will not be affected to continue to monitor the child in the power failure environment.
