The choice of litter. The litter requires water retention, breathability and a certain source of microbial nutrition. The choice of litter should be based on local conditions and timely use. In the south, rice hull, rice bran, bamboo sawdust, and perlite are the main ingredients. Straw and leaf weeds are also very good litter after comminution; northern corn stalk, peanut shell powder, corn cob Powder, grass powder, perlite-based.
Liner thickness requirements. The total thickness of the litter in a typical pig house is about 80 cm to 100 cm. The mat is thick in winter and the litter is relatively thin in summer. The thickness of bedding shall not be less than 45 cm, and the volume of single fermented mattress shall not be less than 10 cubic meters.
The litter fermentation operation method. Pretreatment of HM litter fermentation base:
1 During the fermentation of litter in the winter, the HM litter fermentation base is first soaked in warm water at 30°C to 40°C for 8 hours to 10 hours in order to activate the HM litter fermentation base.
2 When fermenting litter in other seasons, mix HM litter fermentation base with finely-mixed cornmeal, rapeseed meal and wheat bran so as to provide microorganisms with various nutrients and increase the contact between HM litter fermentation base and fermentation raw materials. area.
Mixed fermentation
1 Centralized and unified production method: that is, calculate the amount of various litters according to the volume of each pig house outside the house, and mix the litters according to the proportion. In the winter fermentation, the first kind of pretreated HM litter fermentation The base is added into the water in several portions, and water is added while stirring the litter, and the moisture is adjusted to 50%-60%; in the other seasons, the second pretreated HM litter base is spattered into the litter and mixed and stirred. Evenly, adjust the moisture to 50% to 60% (that is, hand hands wet, but the fingers do not drip), and then stack into a rectangular box that is about 1 meter high, 1.5 meters to 2 meters wide, and has an unlimited length. Half is covered with woven bags or long straw materials to reduce the evaporation of moisture, and then the thermometer is inserted into the material at 30 cm. Mixing and stacking fermentation, keeping the temperature above 55°C for 5 days, then turning over, turning for 5 days after the temperature reaches 55°C, then reducing the stack height until the temperature drops steadily to the ambient temperature. Fill in the pig house. After the above fermentation, not only the litter is harmlessly treated, but also the functional microbial strain can be proliferated and colonized.
2 directly within the production method: the selected litter, HM litter fermentation base in proportion in the piggery fermentation tank fully stir evenly, add water and stir, adjust the moisture to 50% to 60%, and then carry out the accumulation of fermentation. The fermentation method is the same as the off-site method. Note that a certain space must be reserved in the fermentation tank to facilitate padding and turning until the operation is completed.
Paving mats. After the litter has undergone harmless treatment, the temperature drops steadily, and when the litter is spread, there is a refreshing acid odor, there is no abnormal odor, indicating that the litter has been fermented successfully, and the litter can be spread out (carried) to each column. House, laying height as required.
After the litter is laid flat in the bar, wait 24 hours to see if the temperature is stable before entering the pig.
NVR Kit China's domestic level
China Telecom's Global Eye and the former China Netcom have developed remote video monitoring in conditional households. For example, the wide view video monitoring business has been launched in China Netcom's Shanxi, Shandong, Jilin, Zhejiang, Henan and other provincial companies in the early stage, and has been widely welcomed by customers. The wide view business has developed rapidly. In the first half of this year, only Hubei Netcom's "wide view - God's Eye" business has developed more than 500 households. With the rapid development of family information technology, users' demand for family security is becoming stronger and stronger, and the broad horizon will maintain rapid development. China Mobile is also developing mobile MMS monitoring represented by "Handyantong", and 3G video monitoring is also being tested and commercially tested. It is difficult to develop and promote home video surveillance because of the huge data and signal flow relying on the network and the need to deploy home gateways and cameras.
Video monitoring is mainly used in the communities closely connected with families in the industry field, but it is still less used for home monitoring. Under the guidance of the policy of safe cities and safe families, the domestic family monitoring will begin to rise with the continuous improvement of family network environment, the improvement of users' consumption ability, the growth of security awareness, and the increase of independent living families. The integrated video monitoring that integrates limited, wireless access and linkage alarm will become a development trend. Full service operation has arrived. Operators will certainly provide users with wired and wireless diversified technical monitoring means. Through business integration, they will bring users endless monitoring services. Monitoring realizes the discovery and prevention of family safety, and also reflects family care. In addition, efforts should be made to solve the problem of security. Therefore, family monitoring needs to gradually increase some new functions and applications such as linkage alarm and security services, such as emergency help, interaction with public security, medical care, housekeeping, and calling.
