Pumpkin is a plant that is highly adaptable to soil, water, and fertilizer conditions. Because of its strong water-absorbing and fertility-absorbing ability, it is easy to “spread the belly†(excess nutrition) when planting or applying excessive nitrogen fertilizer on fertile soil, resulting in too many plant leaves, and less flowering, falling flowers, and falling “naughty†( Commonly known as madness) phenomenon. There are three conventional rescue methods: First, stop the application of nitrogen fertilizer to prevent the continued excess of nutrients; Second, cut the main root, press the shoots, promote internodes adventitious roots, expand the ability of the roots to absorb soil moisture and inorganic salts, slow the transport of nutrients to the growing point , Suppressing leggy; Third, the pruning to the leaves: that is, when cutting the main root, pressing the branches, remove the side vines at the male flowers and leaves, cut off the old leaves and the part of the arbor and some of the leaves caused by the shade, improve the field microclimate, promote more flowering, more The knot "girl".
In addition, there is a simple "breakthrough" trick. The method is to use a fruit knife to cut the mouth along the direction of the growth of the vine on the main vine 33 centimeters away from the pumpkin culm, and insert a "bolt" made of charcoal into the straight mouth. If there is no charcoal, bamboo sticks or small sticks of hard wood can be used to cut the size of the stick into the vine.
By adopting the above methods, it is possible to effectively suppress the madness of the melon plants, promote more female flowers, prevent melons, and significantly improve the rate of melons.
Mini Camera Introduce
1. Wired camera
The advantages are that the technology is mature, the industrial Network Camera technology is directly transplanted, the signal interference is not feared, and it is stable and reliable;
The disadvantage is that the installation is complex and requires wiring. It can only be accessed through a computer. The scope of use is limited and it is not suitable for home use.
2. Wireless camera
The advantages are that there is no need for wiring, the installation and increase of cameras are relatively convenient, and the cost of Internet access is low;
The disadvantage is that it will be interfered by the signal, which may affect the definition and transmission speed of the picture.
Extended data
Now the technology of solar energy monitoring is mature, and solar energy can be used to solve the problem of power supply. Outdoor monitoring can also choose more advanced solar energy monitoring. Remote monitoring without power and network is no longer an imagination.
1. Simple installation: install by yourself without inviting construction personnel;
2. Adjustable angle: 360 degree rotation, no dead angle monitoring;
3. No electricity connection: solar power generation and built-in lithium battery power supply;
4. No wiring: no wall chiseling or decoration damage.
matters needing attention
The configuration of the solar power supply system requires the customer to provide the total power consumption of each load equipment,
It is necessary to know the local lighting conditions and the duration of continuous operation of the equipment
