Ginger is essential in daily cooking. Almost every household in the countryside will grow its own. Ginger likes to grow in a warm and humid place. Therefore, ginger is grown and the temperature and humidity should be controlled. For vegetable growers, no matter what the vegetables are, high quality and high quality are very important. It is important to understand these points in order to produce high quality ginger.
Ginger growth habit
1. Ginger plants can only grow in the frost-free period. The optimum temperature for growth is 25-28 °C. When the temperature is lower than 20 °C, the germination is slow. When the frost plants are withered, they are frosted, and the roots completely lose their ability to germinate.
2. The growth of ginger has requirements for light intensity. It is resistant to yin and not strong, and the requirements for the length of illumination are not strict. Therefore, when planting, we can choose some shaded sheds or shades to cover the shade. It can effectively avoid the influence of intense light on the growth of ginger.
3. The root system of ginger itself is not very developed, and drought tolerance and labor resistance are relatively poor, so the requirements for moisture are very strict. In the production process, the soil is too dry or too wet to have a great impact on plant growth. When planting, it is necessary to do irrigation and drainage measures. When it is raining, it should be drained in time. When it is dry, it should be irrigated in time.
4, ginger growth requirements for the soil have two aspects, one is the requirements for soil quality, and the second is the soil nutrient requirements. In terms of soil quality, it prefers loose soil or sandy loam. More sticky soils can affect the growth of ginger and cause poor growth. Poor growth can also occur when the soil is poor.
How to choose seeds for ginger cultivation?
The seed of ginger is about 70 grams. In the selection of seeds, it is necessary to select high-quality seeds with full particles, so that the survival rate is relatively high. Don't blindly pursue the quality seeds that others have said, and it is best for those who are in their own region.
What is the specific time for ginger cultivation?
When to plant, depending on the temperature. The temperature most suitable for growing ginger is about 15 degrees Celsius. Under normal circumstances, this temperature will be in the middle of April, so many areas will choose to plant before and after Qingming. Of course, the specific time is also based on the local climate, based on temperature. Choose a sunny day when planting.
Management points after ginger planting
1, reasonable topdressing
Ginger is a fertilized and fat-tolerant crop. In the range of certain fertility, the level of fertilizer is closely related to the value of ginger. The amount of fertilizer required for ginger growing season is large. Therefore, in addition to applying the base fertilizer, proper topdressing should be carried out. Ginger has a prosperous growth period, and the demand for nutrients has increased. Therefore, it is necessary to do a good job in plant nutrient supply.
2, water management
Ginger flourishes in the growing season, the physiological activities on the ground and underground are very active, and the growth is increased. At this time, it is necessary to pay attention to make up the water, and sprinkle water every 7-10 days. Conditional growers can use plastic hoses to pump water to the fields, or install sprinkler irrigation equipment to meet the moisture demand of ginger during the growing season.
3. Pest control
The common diseases in the vigorous growth of ginger are anthracnose and ginger mites, while the pests have noctuids and thrips. Ginger disease, also known as ginger rot, ginger soft rot, is a bacterial disease caused by Pseudomonas. The first damage to the roots and ginger, the diseased ginger is initially water-stained, yellow-brown, and the interior gradually softens and decays, kneading the contaminated white juice and smelling. The stem is diseased and dark purple. The internal arrangement is brown and decayed, the leaves are wilted, the leaves are yellowish, the margins are curved, and eventually they die.
Regarding ginger blast disease, it is mainly based on prevention. Before the cultivation, the ginger can be treated with chemicals to reduce the strain of ginger. When the central diseased plant is found in the field, it should be taken out and burned in the field, and lime powder is sprayed in the diseased hole. Disinfect and timely spray the adjacent disease-free plants to reduce the onset of the disease.

When installing security Outdoor Camera, you should first choose the monitoring host. Do you want to add a monitoring card to your computer, or do you want to use an embedded hard disk recorder as your monitoring host. The computer monitoring card is more suitable for places that are familiar with computer installation, have professional personnel on duty, and have more functional requirements. Its overall investment is relatively low. Since the monitoring card is installed in the computer, the computer needs to be started 24 hours a day; As for the latter, it does not require professional knowledge, nor does it need to be on duty, and it is relatively simple to operate.
To install security monitoring equipment, it is necessary to determine how many cameras are installed, and the quality and monitoring range of the cameras are affected. It is preferred to determine how many cameras are used for monitoring, and then determine the camera lens monitoring range according to how many cameras are available. Therefore, the distance from the camera to the monitoring point and the monitoring area must be clear. The infrared supply network recommends using the camera of 480 TV line, because it is more in line with that definition.
When installing security monitoring equipment, the third consideration is whether the camera has night vision function. If the monitoring is installed in a dark place, it is necessary to consider using a camera with infrared night vision function.
The security monitoring equipment can be installed via wired or wireless transmission. Although the cost of wireless network is relatively high, it can save a lot of installation trouble and make the monitoring site more beautiful. However, the installation of wireless network monitoring equipment should take into account the environmental problems of security sites. Cement building materials will shorten the wireless transmission distance, and metal building materials may complete the shielding of wireless signals. The infrared transmitter and infrared receiver should be far away from other appliances to avoid interference. Because the price of wireless network is almost twice that of wired transmission monitoring equipment, I suggest using wired transmission installation.
On site monitoring and network monitoring When determining the installation of the monitoring system, you should consider whether you need network functions. That is, if you need to monitor and control the monitoring site on the Internet at any time, you need to select a monitoring host with network functions. Avoid no network transmission function after installation.
A complete security monitoring equipment should at least have three parts: surveillance camera, PTZ and decoder. The following are their installation methods:
