Organic Fertilizer is different from traditional fertilizer. Ihe source of organic fertilizer is from plant, animal, or mineral that is applied to plant without any processing. It plays an important role in the sustaining development of agriculture. Organic fertilizer . It can add organic matters to soil; Adjust soil PH and improve soil fertility; Increase plant resistance and increase plant yield; Raise the plant nutritional level for good-quality fruit.

Ground source heat pump construction scheme and design
We all know that the correct way of ground source heat pump maintenance is very important to the maintenance of ground source heat pump, which can not only prolong the service life of the product, but also affect the efficiency of the product, but ground source heat pump construction as a source Heat pumps use the premise, only to ensure that it is healthy to complete the task, after which everything can be established. So ground source heat pump in the construction process, ground source heat pump construction and design is how to show it? Ground source heat pump construction scheme and design 1, before the construction should be prepared before the construction of the project survey data, design documents and construction drawings, and approved the construction design, buried surface should be ground clean, weed elimination, Debris, the formation of space, into the scene of the buried pipe and pipe fittings should be checked piece by piece, damaged and unqualified products are strictly prohibited to use, should be used to manufacture short pipes, fittings. 2, buried pipe connection requirements should be used hot melt or fused connection, vertically buried heat exchanger U-bend connector should be selected complete U-shaped elbow finished product, should not be used straight pipe simmer Elbow, vertical tube heat exchanger U-shaped tube group corresponding to meet the design requirements, the group of good U-shaped tube open end should be promptly sealed. 3, drilling is vertical pipe jacking construction of the most important process. In order to ensure that the hole wall remains intact after completion of the drilling construction, if the soil quality of the formation in the construction area is relatively good, the naked hole drilling can be adopted. 4, under the tube Under the tube is one of the key projects, because the depth of the tube determines the total amount of heat, so you must ensure that the depth of the tube. The down pipe method has artificial lower pipe and mechanical lower pipe. Before the lower pipe, the U-shaped pipe and grouting pipe should be tied together, and the lower pipe should be constructed immediately after drilling. 5, grouting Sealing grouting well also known as backfill process. Before backfilling should be carried out on the buried pressure test to confirm no leakage before backfilling. Correct backfill to achieve two purposes: First, to strengthen the heat transfer between the pipe and the borehole wall, the second is to achieve the role of sealing, to avoid underground aquifers by surface water and other possible pollution. 6, the installation of horizontal ground tube heat exchanger Laying the bottom of the trench should be laid before the equivalent diameter diameter of the sand, the installation of the pipe should not be broken, kinks, the sand shall not have stones, turning should be smooth, and Fixing measures. In the outdoor temperature is below 0 ℃ should not be buried tube heat exchanger construction. Because of its high efficiency and environmental friendliness, the ground source heat pump has been included in the category of renewable energy by the state and has been greatly popularized. However, due to its complexity compared with the traditional system, pre-construction design and construction process need to be prepared, At the same time also have to prepare certain technical standards and requirements.
