What to do if coriander does not emerge

Seed treatment

Seed treatment is a very important step in growing coriander. Why do you say that? Because the seeds of coriander are small balls with very hard shells, it is very difficult to emerge.

The treatment method is to put the seeds in a plastic bag and roll them with a bottle or a rolling pin; or put the seeds in a dustpan and rub them with your hands. In this way, the seeds will be divided into two, and the real seeds of coriander are hidden in the shell.

sowing

Coriander is sowed by furrow sowing. The specific method of furrow sowing is to dig the ground into a small ravine, and then sow the seeds in. The coriander is suitable for dense planting, that is, to sprinkle more seeds, because the coriander grown in this way is tender and delicious .

management

Even if the coriander seeds are treated, the seedling time will take about ten days and a half. This is twice as fast as the untreated seeds, so friends should be patient! Because coriander is slow to emerge, if the middle soil is dry, you need to make up Water once.

The management of coriander after emergence is simple, just watering and weeding are enough. When the seedlings grow to seven or eight centimeters high, you can add some fertilizers while watering them to speed up the growth and make it fresh and tender. When the coriander grows to more than 15 cm, it can be harvested slowly.

What is Battery Mini Camera

Micro camera is a product of modern high-tech, also known as micro monitor. It has the characteristics of small size, powerful function and good concealment.

Micro cameras are widely used in aviation, commerce, media, enterprises, institutions, families and other industries. The appearance of micro cameras has brought convenience to people's lives, and at the same time, some phenomena related to corporate secrets and personal privacy have also emerged A9 Mini Camera
Wireless
Wireless equipment is used stably in domestic wireless environment. The micro wireless surveillance camera has the characteristics of high stability, high speed, long distance and multi-point testing. It can play a huge role in the fields of environment, energy, construction, transportation, medical treatment, industrial machine condition monitoring, etc., especially when the cabling is complex, the cabling cost is high, the long-distance and large-scale transmission of data and the mobility demand is high. Secret Video camera
The main structures and components of the camera can be listed from the working principle of the camera:
1. LENS
Lens structure, consisting of several lenses, including plastic lens or glass lens
2. Image sensor
It can be divided into two categories:
CCD (charge couple device): charge coupled device
CMOS (complementary metal oxide semiconductor): complementary metal oxide semiconductor
3. Digital signal processing chip (DSP)
There are many DSP manufacturers, such as VIMICRO 301P/L, SONIX 102/120/128, ST (Logitech LOGITECH's DSP provider), SUNPLUS (SUN+focuses on the development of CIF and VGA for single chip, but the image quality is average), PIXART (original phase), PAC207, SQ930C, etc.
4. Power supply
Two working voltages are required inside the camera: 3.3V and 2.5V. The latest process chip can use 1.8V.

Some cameras also use video transmission lines for synchronous power supply without external power lines.
