The reason of iron deficiency: Peach tree iron deficiency is often related to the soil pH, dry humidity and fertilizer habits, therefore, can not make up iron for iron supplementation, but should thoroughly understand the cause of iron deficiency in peach trees, fundamentally solve the peach tree Iron deficiency problem. One reason: Soil compaction, lack of oxygen in the roots. Most of the yellow peach leaves are peach orchards lacking cultivator. The soil is not loose, and the air permeability is poor. The roots of peach trees are severely deprived of oxygen, resulting in the inability of roots to inhale and causing iron deficiency. Second reason: less water, soil drought. Although there was no serious drought in the area, it had been a long time since the rain had passed. The ground water evaporated and the salt was concentrated on the surface of the soil, which inhibited the absorption of iron by the peach tree. Reason 3: Saline is too high. Alkaline soils are prone to iron deficiency. Limestone soils, in particular, are more likely to cause acid-base imbalances and iron deficiency symptoms. Reason four: Improper fertilization. Normal use of carbon and ammonia, too much phosphorus, nitrogen and phosphorus too rich, a long time will also affect the peach inhalation of iron. Iron catalyzes the synthesis of chlorophyll, and iron is one of the constituents of respiratory enzymes. When chlorophyll synthesis is inhibited when peach is iron-deficient, it will show chlorosis, yellow leaves, and even whitening. Control measures: Improve the soil. When topdressing peach trees, apply 2 kg of no-tillage fertilizer per acre and pour enough water after topdressing. Normally, when topdressing peach trees, organic manure or no-tillage fertilizer should be added appropriately to increase soil organic matter content, change the physical and chemical properties of soil, and release fixed iron. Irrigation and alkali reduction. The fruit trees are generally filled with water once, so as to promote the settlement of saline and alkaline sediments and adjust the pH. Artificial iron supplementation. Each fruit tree chelating iron 40 grams + 50 grams of blue Jian (microelements), 20-30 kilograms of water at the edge of the canopy drip irrigation, the effect is significant; can also be used 0.3% -0.4% ferrous sulfate solution or 0.1 %-0.2% chelated iron solution + 4000 times liquid Shuofeng 481, spraying the leaves, spraying once every 5-7 days, spraying 2-3 times.

1. If it is to be fixed outdoors with convenient wiring, it is better to install wired cameras;
2. If you are at home or need to change the monitoring location at any time, 4G wireless monitoring will be more convenient;
3. With the development of solar monitoring technology, outdoor installation of solar monitoring will be better.
Advantages and disadvantages of wired cameras and wireless cameras
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
