The spring growth stage of winter wheat from greening to picking the flag, which lasts for 50 to 60 days, is a critical period for the formation of yield. Therefore, doing a good job of spring management of wheat has a very important role in improving wheat yield, the most important of which is to do a good job in fertilizer and water management.
First, return to the green period. For the middle-yielding wheat fields with poor soil fertility, especially the de-fertilized weak seedlings without winter fertilizer should be applied to the green fertilizer. In the wheat fields with excessive precipitation before winter and winter or overwintering winter water, if the soil moisture in spring is appropriate, it may not be poured back into Qingshui. Reviving timely topdressing fertilizer, usually applied to the soil slurry return period, if the soil moisture is poor, chase turning green manure must be turning green and pouring water together. The amount of fertilizer applied can generally be 10 to 20 kg per mu of standard nitrogen fertilizer, and it should be deeped to prevent nutrient loss. Dryland wheat without watering conditions, in addition to draw hoe suppression of soil moisture and drought, the soil in early spring to seize back the pulp of moisture or rain by ditching fertilizer, to be buried deep Shi Yan. To grow too strong before winter, there is the phenomenon of Tuofei wheat fields, to draw hoe in the early spring, clearing the ridge, on the basis of clean, timely pouring good water turning green, turning green fertilizer topdressing appropriate, to supplement the lack of water and nutrients. Strong seedlings or high-yield wheat in high-yield and high-yield wheat fields should be controlled during the greening period, without fertilizing and watering, in case the middle and late groups are too long and long.
Second, the period of getting up. Wheat rose fertilizer in addition to considering other than growing, and pre-fertilization should also be noted fertility basis, should generally be applied per acre of nitrogen standard 15 to 20 kg, the excess fertilizer green late easily lead to corruption. Of low-yielding fields, wheat fields and Tuofei high yield seedlings, weak seedling old, turning green in the case of fertilizer did not take measures to facilitate or promote inadequate, rose fertilizer to be applied early, got up and re-applied in conjunction with pouring water. For the strong seedlings of high-yielding high-yield wheat fields, the fertilization foundation is moderate or less in the early stage, and the wheat field has no tendency to grow. The fertilization should be early and heavy, and vice versa. For high-yield and high-yield wheat fields, wheat fields with good soil fertility, good fertilization in the early stage, and large populations with a prosperous trend should control the body water. After Wang Miao, it is necessary to take measures such as suppression and deep roots. For plots of high-quality wheat, if the soil fertility and seedlings are generally low or low, it should be combined with watering and fertilization in the rising period on the basis of the control of the greening period. Standard nitrogen application per acre is generally about 30 kg. Late buckwheat should control the fertilizer during the period of getting up.
Third, the jointing period. Strengthening fertilizer management in jointing stage is an important technical link to increase wheat yield. Generally, 25 to 30 kg of standard nitrogen fertilizer is applied per mu. The strong seedlings and the fertile seedlings of the high-yielding wheat fields are usually broadcasted, and the strong seedlings and late buckwheat which are usually cultivated by the cultivation method are the main targets of the main attack of the jointing stage. These wheat fields should be watered at the jointing stage and re-applied with fertilizers on the basis of pre-control or appropriate promotion. The wheat field that has been re-applied to the body has been promoted by the greening and lifting period. The wheat seedlings have been transformed or the fertile wheat fields can be re-applied with joint fertilizers; the wheat fields with insufficient population and few spikes, especially the late-season weak seedlings, Appropriately increase the amount of fertilizer applied. For plots of high-quality wheat, if the soil fertility is higher, the seedlings are stronger or more prosperous, and the time for applying nitrogen fertilizer should be shifted later, and the joint fertilizer should be applied as the boot fertilizer. The fertilization capacity of high-protein wheat varieties in the middle and late growth stages was significantly higher than that of common wheat. It should be combined with watering 5 to 7 kg per acre in the picking stage to the heading and flowering stage to achieve high yield and quality.

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
