Tea gardens can be topdressed by reference to the following methods: Hydraulic Flange Hydraulic Flange,Flange Adaptor,Regular Hydraulic Flange,SAE Flange SHIJIAZHUANG TOPA TRADING CO., LTD. , https://www.topahydraulic.com
Hydraulic Flange fitting inculde SAE Code 61 and Code 62 Code 61 hydraulic fitting flange is intended for for pressures up to 3,000 psi. Code 62 is intended for up to 6,000 psi. Bolt hole spacing and flange fittinghead diameters are larger for the higher pressure Code 62 fittings.
The female port is an unthreaded hole with four bolt holes in a rectangular pattern around the port. The male hydraulic fitting is a flanged head, grooved for an O-ring, and either a captive flange or split flange halves with bolt holes to match the port. The seal takes place by compressing the O-ring between the flanged head and the flat surface surrounding the port. The threaded bolts hold the hydraulic connection together.
How to topdress tea garden?
1. For topdressing application In the early spring season, the use of nitro compound fertilizer as top dressing during mining is quick and effective. Compared with urea, urea can take effect after 7~10 days, the nutrient composition is single, and the ammonia volatilization loss is easy to be formed. The utilization rate is not high and the effect is too late, and the ideal yield increase effect is not obtained. Applying the binary nitro compound fertilizer, it can start to take effect after 3~4 days after application, and the nutrients are not only--(including ''double nitrogen' plus phosphorus), the volatilization loss is small, and the utilization rate is high, which is to promote the high yield of spring bud tea. . recommendations spring and a good choice during the extraction, an interval of 8 to 10 days once administered, the amount per acre 15 kg / second; total administered 5-7 times
2. Applying lightly pruned in late May. Young tea garden (three years or so) In order to cultivate the tree potential, a high-yield canopy is formed, and the pruning is performed after the end of the spring tea in the end of May. At this time, use the opportunity to facilitate the ditching and fertilization after trimming, along the edge of the tea canopy drip line - 4 to 5 inches wide, 3 inches deep in the fertilization ditch, the use of ternary nitro compound fertilizer 35 ~ 40 kg, vegetable cake After 30 kg of dryness, apply it to the ditch and cover the soil. In order to make full use of the high temperature of 6,7,8 three months, the rain is enough, and the temperament of the tea tree is strong, which makes the teapots form early.
3. For 10 years or so tea garden, during the summer and autumn mining period, the interval is about 15 days, and the application of the binary nitro compound fertilizer per mu is 12 kg/time for top dressing. Note: The time for applying top dressing must not be selected when there is dew. It is fine. When it is applied on a cloudy day, you must carry a bamboo pole with you and bounce the particles left on the surface. It is best to bend over the ground inside the awning to avoid burning the young leaves.
