After the shack, what is the top priority before planting

Autumn sorghum vegetables are about to enter the peak period of planting, and rapid mitigation is the key to cultivating strong trees. After the vegetable farmers have shackled the shed, what misunderstandings should be taken before the planting, what measures are taken? The following points are the most important:

Scientific watering Many vegetable farmers often stop watering in order to prevent the high temperature and drought of the soil after planting. Most of them adopt the method of flood irrigation. Although watering can lower the ground temperature, the soil moisture is saturated for a long time, which will affect it. The roots of the breath eventually cause the roots to be damaged, and the root disease can also occur in severe cases.

Preventing high-temperature burning of seedlings often occurs in the case of cloudy and cloudy conditions. The evaporation is large after a cloudy day and the roots are insufficiently absorbed. If such a situation occurs, a small amount of shading and cooling is performed in time, and the leaves are sprayed with foliar fertilizer.

Prevent rain from entering the shed

After the temperature rises, the vents of the greenhouse are widened, and the rainwater can easily enter the shed. At this time, the amount of bacteria in the rainwater is large, which is very harmful to the seedlings. Once rainwater is poured into the shed and the roots of the seedlings have just been planted, the chance of root disease is greatly increased. Therefore, it is necessary not only to strengthen the ventilation of the shed, but also to prevent rainwater from entering the shed to affect the slow seedlings.

Chasing fertilizer to promote slow seedling

The biological bacteria have great protection and growth promoting effects on the roots. When the vegetables in the slow seedling stage are watered, the appropriate amount of biological fertilizer can promote the rapid rooting of the seedlings and inhibit the occurrence of root diseases.

During the slow seedling period of vegetables, due to the high temperature and high humidity in the shed, the resistance of vegetables to the medicinal agent is weak. Therefore, some medicinal agents cannot be used or cannot be used according to the concentration at the flowering and fruiting stage, such as copper preparation, which is easy to inhibit plant growth. Use with caution.

The IOT card of the video surveillance camera needs to be stable enough to keep the flow normal during use without being stopped. After using the IOT network card with defective quality for a period of time, traffic theft or other abnormal conditions suddenly occur, resulting in card suspension, which makes the camera terminal unable to use normally, and may have a significant impact on the business. Generally speaking, video monitoring is event driven or abnormal images (some intelligent algorithms need to be supported) to generate high traffic usage. For example, monitor video playback or live broadcast via 4G/5G remote viewing. Generally, the daily standby traffic consumption is M, and the common definition of video viewing is about hundreds of M an hour.
Currently, for this application scenario, there are also several industry pain points for equipment manufacturers and solution providers:
SIM card adaptation, speed and security issues;
SIM card supply and price stability;
Be unfamiliar with the communication industry and solve the problem of failure;
One point access of multiple vendors.
Honeycomb IoT provides high-speed and stable IoT network cards for security monitoring equipment. Direct connection of operators, including full system, full type and full category IoT SIM cards; Flexible pricing and high cost performance; In addition, it also has a customer oriented efficient management platform, including full lifecycle management and connection management functions.
