China's bamboo forest area is about 1/3 of the world's bamboo forest, of which about 47% is bamboo. According to the business purpose, bamboo forest can be divided into bamboo, bamboo bamboo shoots, bamboo bamboo shoots, pulp bamboo and other types, and they have different requirements in fertilization and production management. Fertilization is also related to the soil conditions of the forest land, of which the 60-80 cm soil layer has the highest fertilization, and the soil fertility higher than 80 cm can reduce the amount of fertilization. The shallow soil layer has limited potential for increased yield and less fertilization. some. Bamboo shoots were used for bamboo shoots. Newly-built bamboo shoots were used for middle-cultivation weeding and heavy nitrogen fertilizer application. Mushi 50 kg compound fertilizer was used as base fertilizer. Each year 5 to 6 months, 50 green tea was buried, 50 kg of urea and 35 kg of superphosphate were applied. Decomposition of 1,000 kilograms of human feces. For high-yielding bamboo shoots, the land can be filled with 200 liters in June, 40 kg of urea, 100 kg of superphosphate, 20 kg of potassium chloride, 1,000 kg of livestock manure in September, and 11 months of mu. 80 kg of feces; 100 months of watering 100 tons covered by bamboo leaves, grasshoppers and other objects 30 cm thick, and then poured 3% of urea water 700 kg. The ratio of nitrogen, phosphorus and potassium fertilization for the bamboo and wood plantation is 5:1:2. The emphasis is on "mainly organic fertilizer, sufficient winter fertilizer, early spring fertilizer, and good fat summer and autumn." Mushi cake fat, pig cow dung, ring dung and other decomposed organic fertilizer 1500 kg, urea 35 to 40 kg (not less than 12 kg at a time), calcium magnesium phosphate fertilizer or superphosphate 50 kg, potassium chloride 30 kg, before the shoot After the shoot, bamboo shoots, pregnant bamboo shoots, wintering period is divided into 4 applications. In addition, about 2,000 kilograms of land and soil were buried, and more than 3,000 kilograms of waste were covered. The timber is fertilized with bamboo for 7-8 months each year. After deep-turning and reclaiming, combined with weeding and ripping, 2,000-kg farmyard manure is applied 3 to 4 times in March, July and November. Urea, cake fat, superphosphate, chlorination Potassium and silicon fertilizer each 50 kilograms. There are also conditions that can be buried in the soil and green 50, covered more than 5000 kg of garbage, or 30 cm thick bamboo leaves, weeds and so on. Pulp and bamboo forest fertilization and fertilization has little effect on the chemical composition of bamboo, but it is 50 to 100 tons per hectare of land, and 30 kg of fertilizer per mu before bamboo shoots can significantly increase production. Fertilization is only one of the measures for high-yielding bamboo production. It must also be combined with comprehensive management measures such as keeping bamboo shoots and raising bamboos, bamboo shoots for bamboo shoots, reasonable harvesting, and maintaining a reasonable bamboo structure.
Small Format Interchangeable Cores (SFIC) are widely used in many applications. The Lock Cylinder needs to be replaced due to staff turnover or other safety issues. It is probably the most popular style of lock used for office complexes, universities, and government buildings around the world.
