Artificial hip joint

The invention provides an artificial hip joint prosthesis which is flexible in adjustment, capable of meeting movement requirements in each direction and high in wear resistance of related contact surfaces to solve technical problems. An implanting tool is improved to reduce operation wounds. The artificial hip joint prosthesis comprises a femoral stem, a femoral bulb and an elastic connector. A far end of the femoral stem can be inserted in a femoral marrow cavity, a near end of the femoral stem extends upwards laterally, an included angle between the axis of an extending end and the axis of the femoral stem under a natural state is 110-140 degrees, the end of the extending end is suddenly thinned into a step shape, a thin section extends upwards laterally by 6-10mm and is used for fixing the elastic connector, one end of the elastic connector is inserted into the thin section and abutted against the step position while the other end of the elastic connector is connected with the femoral bulb, and the joint of the femoral bulb and the elastic connector is provided with a column projection 6-10mm in length. Therefore, arbitrary adjustment of the artificial hip joint prosthesis in each angle is realized, and especially adjustment of a front inclination angle and a collodiaphyseal angle at a sagittal view and a coronal view is realized.

Method for promoting blooming and fruit setting of walnut after freeze injury of late frost

The invention belongs to the technical field of repair and remediation of fruit trees after freeze injury, and provides a method for promoting blooming and fruit setting of a walnut after freeze injury of late frost. The method is used for solving the problem today that the walnut tree is lack of promoting the blooming and fruit setting after freeze injury of late frost and the output is seriously influenced. The method comprises the following steps: after the frost freeze injury, shear the walnut tree according to the freeze injury degree; after the freeze injury, immediately spraying a tree growth recovery liquid formed by mixing Vitamin C, tea polyphenol, thiophanate methyl and water; at the blooming period of a mixed bud of the walnut side, spraying the walnut pollen water suspension liquid; when the walnut fruit is expanded, spraying fruit-setting nutrition fluid formed by mixing ferrous sulfate, urea, sodium borate, monopotassium phosphate and water in ratio. After the frost freezing of the walnut, actively remedy it, promote the secondary sprouting of the walnut, and effectively improve the fruit-setting rate; the method is low in cost and simple and easy to practice; after the frost freezing of the walnut, blooming and fruit setting are promoted. The dug component is strong in resistance to oxidation and good in fertilization; the nutrition component complies with the physiologic demand after the frost freezing of the walnut, and is easy to recover and remedy the growth of the walnut tree; and thus, the walnut tree is less in diseases.

Tool and method for efficient utilization of water and fertilizer for fruit trees

The invention discloses a tool and method for efficient utilization of water and fertilizer for fruit trees. A hole is dug downwards in the vertical direction or approximately vertical direction on the lower side of a plant root on a slope, the tool for efficient utilization of water and fertilizer for fruit trees is installed in the hole and comprises an outer frame comprising coarse pores and an inner frame comprising fine holes, the annular space between the outer frame and the inner frame is filled with water seepage materials to form a water seepage layer, fertilizer is added to the inner frame to form a fertilizer layer, and a water retaining ridge is arranged on the lower side of the hole. By means of the water seepage layer, water flowing by can be absorbed and stored quickly, the water seepage area in the stratum can be enlarged, and the purposes of improving water storage capacity and improving water permeability are realized. Slow and continual fertilizer application is conducted by means of micro-permeation of the fertilizer layer, so that fertilizer storage and automatic fertilizer supplement are achieved. By the adoption of the tool and method, high water storage capacity, quick water seepage and automatic and continual fertilizer application can be achieved for good, labor amount is reduced, and effect is quite good.
