In the growing process, the crop needs the supply of fertilizer. If the iron is lacking, the old leaves of the plant remain green, but the young leaves turn yellow and the veins are still green. When the iron is extremely lacking, the leaves will be whitened, and iron needs to be applied to the crop. Fat supplements. What fertilize iron fertilizer? How to use iron fertilizer?
What is the fat of iron fertilizer?
Iron fertilizer is a fertilizer that has a marked amount of iron to provide plant nutrients. Iron fertilizers can be divided into inorganic iron fertilizers, organic iron fertilizers and chelated iron fertilizers. They are one of the essential micronutrients for plants. Iron fertilizers have a certain effect on the correction of fruit chlorosis. Ferrous sulphate is mainly used for foliar spraying and can also be used as base fertilizer. Organic fertilisers and chelated iron fertilisers are used for spraying, which has better results but higher costs.
How to apply iron fertilizer
The external application of iron fertilizer is dominated by organic iron fertilizers, with small dosage and good effect. The price of chelated iron fertilizer and ferric citrate organic iron fertilizer is extremely expensive, about 12 yuan/kg or more, and the cost of soil application is very high. It is mainly used for extra-root fertilization, that is, foliar spraying or stalk drilling. Fruit trees can be sprayed on leaves, suspended infusions, and nailed nails or drills.
The spraying time is usually selected after 4 o'clock in the afternoon without any wind. After the spraying, the rain should be sprayed once in fine weather. Inorganic iron fertilizer with the spray with the fertilizer solution should not be long home in order to prevent oxidation failure.
The spraying concentration is generally 5-30 g/kg, which can be sprayed with acidic pesticides. In the case of single shot iron fertilizer, urea or surfactant (non-ionic detergent) may be added to the fertilizer solution to promote the attachment of fertilizer solution to the foliage and the absorption of ferritin. Due to the short period of validity of foliar spray fertilizer application, when iron orchards of fruit trees or long-growth crops are to be corrected, they are generally sprayed once every half month or two or three times, which can have good results.

What are the advantages and disadvantages of outdoor solar cameras
Wired cameras and wireless cameras have their own advantages and disadvantages, mainly depending on the purpose for which you install the camera.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
