Problems to be Noted in Corn Production in Spring 2016:

1. Effectively strengthen the construction of farmland water conservancy and timely renovate relevant agricultural machinery.

2, choose a relatively drought-resistant varieties

(1) Selection of control cultivars in each area: These cultivars were planted for many years and had good characteristics such as high yield, stable yield, strong adaptability, and resistance to major maize diseases.

(2) Select the approved varieties with good performance in recent years, especially those with better performance in 2014 and 2015. In early 2015, there were low temperatures, heavy rain, droughts in some areas, and severe droughts in the later period. Therefore, good-quality varieties should have strong drought tolerance.

(3) According to the 2015 corn variety layout recommended by the Jilin Provincial Seed Management Station, select varieties. The variety layout is recommended by corn specialists of the Provincial Variety Approval Committee based on years of careful and scientific analysis of the varieties.

3, adjust the planting varieties: change in recent years in the masses of the formation of "the species more species later," the habit must be planted mature varieties suitable.

4. Select seeds with high seed vigor: High vitality seeds have the ability to increase the emergence rate in the field, resist adverse environmental conditions (strong vitality), enhance the competitiveness of diseases and weeds (fast and neat emergence), strong cold resistance, suitable for early sowing ( Strong anti-low temperature capability, saving planting costs (saving seeding), increasing crop yields and improving seed storage resistance. The seeds with high vitality mainly exhibit high germination power and germination rate, not only high germination rate.

5. Timely land preparation: For the land that has not undergone autumn soil preparation and land preparation, use a large farm machinery for deep soil preparation, with a depth of 20 to 25cm, to achieve straightness, stability and no pollution, and timely repression to reduce soil water loss. .

6, pay attention to sowing time and sowing quality: consider delaying sowing time, when the ground temperature is stable to 10 °C or when the low temperature began to rise when sowing, to prevent the "powder species" occurred. After sowing, it is necessary to pay attention to repression and prevent “runaway”. At the same time, the low temperature in spring is one of the important reasons for the increase of smut in corn silk. Therefore, it is required that seed coating or dressing be used to prevent the occurrence of corn head smut on corn yield.

7. Increase the area of ​​“cultivation by sitting water”: For lands with soil moisture below 20%, it is required to plant water. At the same time, seed germination is an effective measure to prevent powder seedlings from being preserved.

8, for individual early sowing farmers, pay attention to observe the state of the seeds: early sowing farmers, should pay attention to observe the state of the seeds, found that "powder species" imagination, should immediately take the seedlings to fill seedlings or replanting varieties and other remedial measures to protect the whole seedlings.

9, after the emergence of corn, and time seedlings, make up seedlings: time between seedlings must be in the 3 to 4 leaf stage. The seedlings are too vulnerable to underground pests to produce seedlings. The seedlings are too late to injure the roots and produce weak seedlings, which will affect the final yield. If there are seedlings in the corn field, seedlings should be made when the seedlings grow to the 3 to 4 leaf stage. Supplementing seedlings can not be too late, and require the supplement of seedlings of the same size prepared in advance, otherwise the supplemented seedlings are easy to form weak seedlings and will never catch up. In general, transplanting water should be used to transplant the seedlings. Transplanted seedlings must be carried with soil, not to hurt the roots or to injure the roots.

10. Strengthen pre-field management: The main limiting factors for the high quality and high yield of corn in Jilin Province are effective accumulated temperature and insufficient water. Good field management can regulate soil temperature and moisture, promote corn growth, maturity and high yield. In view of the current low-temperature drought, it is recommended that past important field management measures be restored. Seedling deep pine: The seedlings of maize are usually loose at the seedling stage when the seedlings grow to 2 to 3 leaves, commonly known as "plough before a shovel," and the depth should be more than 25 cm. Deep seedling loosening can significantly increase the temperature, which is conducive to the activities of soil microorganisms, promote the decomposition and transformation of soil nutrients, and promote the growth and absorption of roots, laying a good foundation for the growth and development of high-yield corn.

Indoor PTZ Camera

What is Indoor PTZ Camera

PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.

PTZ: In the security monitoring application, it is the abbreviation of Pan/Tilt/Zoom, representing the pan tilt omnidirectional (up and down, left and right) movement, lens zoom and zoom control.
Automatic tracking is divided into three types: one is through embedded video encoder, also known as intelligent visual server; the other is PC software; the other is to directly write the tracking algorithm to DSP chip, and then design the DSP chip as a hardware circuit on the high-speed ball motherboard, and the high-speed ball is directly read. Among the three types, the third type is used most in the current market.
The intelligent vision PTZ automatic tracking and monitoring system consists of an intelligent vision server (responsible for intelligent analysis and command) and a high-speed spherical camera (responsible for tracking targets). The automatic PTZ intelligent tracking function enables the camera to automatically PTZ drive its own PTZ and zoom lens, and automatically control the PTZ camera to rotate the PTZ in all directions and zoom the lens, and perform visual oriented automatic tracking for the locked moving target, so as to ensure that the tracking target continues to appear in the center of the lens with a close-up image, so that the security personnel can see the information more clearly, It can also be used for obtaining evidence afterwards. The automatic PTZ tracking module makes up for the narrow field of vision of fixed camera monitoring, which is an essential function of a perfect security monitoring system.
The intelligent vision PTZ automatic tracking and monitoring system has the target analysis function, and is equipped with a high-resolution camera, a large magnification optical zoom lens and a high speed PTZ, which can automatically capture suspicious targets quickly and accurately. By setting the preset position intelligent vision PTZ automatic tracking monitoring system, the preset position scanning, automatic cruise and other functions can be realized, and many special requirements of intelligent monitoring can also be realized. In addition, the intelligent vision PTZ automatic tracking and monitoring system also has the advantages of beautiful appearance and strong concealment, so it is very suitable for public security intelligent monitoring applications in airports, squares, rail transit, villas, government administrative units, military regions, museums and other types of places.

The automatic PTZ tracking and monitoring system integrates optics, electronics, machinery, information processing and network, and is composed of camera, power transmission, motion control device, image analysis, recognition, compression and communication based on high-speed parallel processing. It has the functions of video camera, position control, orientation and lens preset, moving object detection, recognition and tracking, flame and smoke detection and alarm, etc. It can be widely used in buildings, banks, airports, stations, customs, transportation, power, factories and mining enterprises and other security monitoring occasions.
