Summer mushrooms must be six defense

A lack of nutrition. Nutrition is the material basis for the growth and development of straw mushroom, and it is an important condition for high yield and high quality. The nutrition of straw mushroom is mainly nitrogen sources, carbohydrates, minerals, and physiologically active substances. In a well-fed mushroom bed or haystack, the mycelium grows vigorously, the fruit body is hypertrophied, the mushroom production period is long, and the yield and quality are good. Therefore, in the cultivation of straw mushrooms, should choose high-quality, golden yellow straw, should not use the rotten metamorphosis of straw, and in the straw heap add some soybean straw, chicken, ducks, pigs, cattle dung powder and other organic matter, to supplement Nitrogen source is conducive to high yield and high quality. Second, there are insufficient waterproof points. Water not only constitutes an important part of straw mushroom, but also all nutrients can be absorbed and utilized by the mycelium only when dissolved in water. The metabolites of straw mushroom must also be dissolved in water to be excreted from the body. The lack of water will hinder the growth and development of straw mushroom. And even make it dry and dead. However, if there is too much water, it will affect the ventilation of culture materials, inhibit the respiratory process, resulting in a large number of death of mycelium and buds. Practice has proved that the moisture content in the substrate or straw is about 65% suitable for the growth and development of the mushroom mycelium. The relative humidity of the air around the mushroom bed is 85%~90%, which is most suitable for the growth of grass mushroom fruiting bodies. Three against sunlight. Spore germination and mycelial growth of straw mushroom generally do not require sunlight, but the formation of fruit bodies requires sunlight. Under completely dark conditions, it is difficult to form fruit bodies. Diffuse light can promote the formation of fruit bodies and promote its robust growth, increase resistance to diseases and insect pests, promote the accumulation of pigments, and make the color of fruit bodies darker. However, strong direct light has an inhibitory effect on fruiting bodies. Therefore, the cultivation of straw must be covered with grass cover on the open field, and it is advisable to use the sparse shade under the sunlight that can be selected by the “three-points and seven-points” shade. Four anti-temperature discomfort. The straw mushroom is native to tropical and subtropical regions and is a type of high-temperature agaric. The temperature range for mycelium growth is 20°C to 40°C, and the optimum temperature is about 32°C. The optimum temperature for fruit body growth is between 30°C and 32°C. The temperature within the haystack develops at a suitable fruit body of 35°C to 38°C. Therefore, when the mycelium or fruit body is below or exceeds its temperature range during the growth process, powerful measures should be taken immediately to restore the normal growth temperature. Five to prevent rapid air flow through. Straw mushroom is a joyous saprophytic bacterium, and sufficient oxygen is an important condition for the normal growth and development of straw mushroom. If oxygen is insufficient and carbon dioxide is accumulated too much, mushroom buds often stop growing or die due to respiration inhibition. However, if the ventilation is too large, the water will be dispersed too quickly, which will also be detrimental to the growth of straw mushroom. Therefore, it is best to choose the place where the air convectively grows. Six anti-acid alkalinity imbalance. The pH value is an important factor that influences the growth and development of straw mushroom. Practice has proved that the optimum pH for the growth and development of straw mushroom mycelium is 7.2-7.5, the optimum pH for the formation and growth of fruit bodies is about 7.4, and the optimum pH for spore germination is 7.4-7.6, if the pH is too large, it will affect the normal growth and development of straw mushroom.

Network Camera NVR CCTV Kits

The functional mode of NVR technology application is relatively flexible and can meet the functional requirements of today's video monitoring system to a large extent. The small NVR scheme with NVR technology as the core has the advantages of small scale, flexible operation, convenient use, economy and practicality. Its front end mainly supports 8-way 720P high-definition video image access with high-definition video camera, and then realizes the centralized management and real-time storage of high-definition video image information through NVR technology. In addition, this small NVR scheme can also support remote management of video images, preview analysis of video images, real-time upload of gigabit network interface video image data, local preview, video playback and other functions. The small NVR high-definition video scheme has a high overall cost performance ratio, simple system and high operational flexibility. This small NVR high-definition video monitoring system is widely used in the centralized video monitoring field in small areas such as companies, factories, family villas, offices, shops, supermarkets, etc.

With the further increase of functional requirements for high-definition video monitoring system, the video monitoring system is required to have the technical performance of expansion, cascade and standard ONVIF communication protocol. The HD cameras of different manufacturers and brands at the front end of the video monitoring system can be organically interconnected through NVR equipment. In this way, a unified functional integrated LAN can be built through NVR to achieve NVR cascade, expansion and mass storage in the video monitoring system. In addition, a centralized advanced application management technology platform is built at the back end through NVR expansion, which can uniformly manage and configure the NVR device group to achieve multi-user forwarding and various application function services (forwarding/management server group) within the region, mainly including: forwarding server, management server, storage database, on-demand server, advanced client application software and other functional modules. The medium-sized NVR high-definition video system is usually used in the medium-sized high-definition video surveillance projects with routes below 1000. Its advantages are that NVR can achieve distributed layout and centralized and unified storage, and its operation stability is high. The back-end technology platform carries out unified management and application, and can achieve multi-user and multi-level integrated and unified application services. The secondary medium-sized network mainly focuses on the urban video monitoring architecture of district, county or prefecture level cities. It realizes the storage of video image data and the centralized communication management of access to front-end equipment through NVR, thus realizing the storage, management, client video image preview, local decoding on the wall and other service application functions of front-end high-definition camera video. At the same time, it can also be authorized by the provincial video monitoring center, The video image information can be previewed, controlled and shared among clients of different levels of users, fully meeting the normal video monitoring function requirements of secondary users in cities such as prefectures, counties and cities.
On the basis of the secondary network structure, a large NVR high-definition video system is built by converging into the primary network through private networks, optical networks, and public service networks. The storage and forwarding services of the primary network are realized through the industrial control NVR, and the redundant and safe backup of the video monitoring system is realized at the same time. This distributed multi-level coordinated back-end centralized management network mode greatly provides the overall function and fault tolerance of the video monitoring system, highlights the ease of operation and reliability of the high-definition video monitoring system based on NVR technology, and meets the flexibility, multi-function performance, sharing Emergency handling and other functional requirements.

NVR technology has been widely promoted and applied in urban safe storage, national security and other engineering projects with its own advantages in many aspects. Driven by market and technology, NVR technology will become the mainstream technology in the field of urban security high-definition video surveillance, with very strong theoretical research and practical application prospects
