The soil peanuts are resistant to drought and barrenness, and sandy soils with good permeability and large temperature difference between day and night are preferred. The plot should be selected from land that has not been planted with peanuts or legume crops. It is better to use crops such as scallions, corn husks, and vegetable pods.
Choosing the superior species to cover the mulching film can increase the soil temperature, enhance the soil conservation ability, and increase the fertilizer utilization rate. In order to increase planting efficiency, cultivar-covered cultivation should select medium and large fruit type varieties with large yield potential, high yield, and strong disease resistance.
There are often two types of misunderstandings at the time of sowing production: One is the early sowing period, because the temperature in early spring is unstable, and the lack of seedlings is often caused by the lack of ridges, which leads to severe defamation. The other is delayed sowing, because the role of plastic film coverage can not be fully realized, the corresponding delay in the listing period will affect earnings. Tests have shown that the sowing date of mulching spring peanuts is generally about 10 days earlier than spring sowing in spring, and April 15-20 is appropriate.
The suitable density density of spring peanuts should not be too small or too large. Smaller crops will affect yield, resulting in a decrease in the yield of excessive single plants, wasting seeds, and reducing yield. In production, a double-line cultivation mode is generally used. The row spacing is controlled at 30 cm, the spacing between plants is 15 to 18 cm, and the mu density is about 10,000 holes. Each hole has two grains and the amount of mu is about 17 kg.
Does the solar PTZ Camera System Kits work well
In fact, there are no network and no electricity cameras, but they have certain limitations. The working time of a camera with batteries or external solar panels is limited.Monitoring without network means that mobile phones and cameras can only be seen within a certain range of 5~10 meters.
Therefore, no network and no power is just a gimmick. We must pay attention to distinguish when buying.
Is the Solar Camera easy to use
Jiajie intelligent surveillance camera is very good
Advantages and disadvantages of solar monitoring
Probably.
Generally, offline display has the following two conditions.
One is that the installed 4G card has no traffic and cannot provide network connection for monitoring;
The other is that there is a problem with the signal receiving device, which makes it unable to connect to the network. Therefore, the user can access the APP connected to the monitor to check whether there is still traffic on the 4G card. If there is still traffic, there is a problem with the monitoring; If there is no traffic, the renewal fee can continue to be used.
Which is the best solar Outdoor Camera
It may be that the poor contact of the power plug causes power on, heating and power failure, or it may be that the camera's internal control motherboard fails, causing power on for several minutes and automatic power off protection.
The camera works continuously, and the internal chip may overheat, which also exists in many SLR cameras. Some cameras impose time limits on continuous shooting. Centralized power supply with high-power switching power supply
Disadvantages of camera solar power supply
The main advantages of solar photovoltaic power generation are:
(1) Simple structure, small and light volume;
(2) Easy to install, easy to transport, short construction period, and short time to obtain energy;
(3) It is easy to use and maintain, and can work normally in the temperature range of - 50 ℃~- 65 ℃;
(4) Safe, reliable, noiseless, pollution-free, and absolutely clean (pollution-free);
(5) The advantages of building roofs can be used without the restriction of resource distribution regions; For example, areas without electricity and areas with complex terrain;
(6) The rate of price reduction is fast, and the time for energy repayment may be shortened;
(7) It can be matched with the battery to form an independent power supply, or it can be connected to the grid for power generation.
(8) Local power generation and supply without fuel consumption and transmission lines
The main disadvantages of solar photovoltaic power generation are:
(1) Low solar energy density and large coverage area;
(2) Photovoltaic power generation is intermittent and random;
(3) Solar energy resources in various regions are not available, so photovoltaic power generation is highly regional.
