The invention provides a process for spraying fluorocarbon wood grains on the surface of a sectional material. At first, first PVDF fluorocarbon powder is sprayed on the surface of the sectional material and is roasted at the intermediate temperature of 150+ / -10 DEG C for 15+ / -3min, so that the PVDF fluorocarbon powder forms a gelling state on the surface of the sectional material; after cooling, the sectional material is sprayed with PVDF fluorocarbon render face-colour powder for the second time and is roasted at the intermediate temperature of 150+ / -10 DEG C for 15+ / -3min to form a gelling state, and is fully integrated with first-layer spraying powder; after the sectional material is sprayed with PVDF fluorocarbon powder for twice, the liquid PVDF fluorocarbon paint is sprayed on the wood grain of the sectional material according to the principle of PU roll printing and is roasted at the high temperature of 220+ / -10 DEG C for 40+ / -3min so that the solid PVDF fluorocarbon powder and liquid PVDF fluorocarbon paint are fully integrated and cured; finally, fluorocarbon wood grain effect is obtained on the surface of the sectional material. The fluorocarbon wood grain has the characteristics of strong weather resistance, heat resistance, low temperature resistance, chemical resistance, and low friction.

The invention relates to a breast injectant prescription of cefquinome sulfate in a dry milk period and a preparation method thereof. The prescription comprises a suspending aid and a solid dispersing carrier, and is prepared into an almost white and light brown ointment by virtue of a special process.

The prescription, which is in the dosage form of an ointment, has multiple advantages such as high bioavailability, slow release and long action time compared with an injection; the ointment, after being filled into a milk chamber through a milk vessel, can be sealed on a nipple hole, so as to prevent bacteria from moving reversely and invading the milk chamber through the nipple hole and other phenomenons.

The invention relates to an ecological geotube submerged breakwater which comprises ecological geotubes, filled woven bags and protection blankets. The protection blankets are laid on a riverbed parallel with a dike dam of a river bank, the ecological geotubes and the filled woven bags are filled with sand and soil, each protection blanket is provided with three ecological geotubes shaped like a Chinese character 'pin', the ecological geotubes axially adjacent in an end-to-end mode are stacked in an end-to-end staggered connection mode, and the filled woven bags are stacked in seams among the three ecological geotubes of each protection blanket. The ecological geotube submerged breakwater can resist repeated impact of water currents, wind and waves for a long time, the ecological ecotubes are filled with sand and soil and are stacked, the submerged breakwater which is high in strength, quality and density and not prone to collapsing can be formed, relatively stable ecological environment of plants in a water body of the river bank can be maintained, influences of the wind and waves on the plants in the water body of the river bank are reduced, and underwater conditions are stabilized. Meanwhile, due to the stacking method, needed materials are simple, the stacking efficiency is high, and the stacked submerged breakwater can resist erosion of wind, waves and water currents and is not prone to deforming and collapsing and high in operability.

The invention discloses a bird repelling device for grape planting.

The invention further discloses a bird repelling method using the bird repelling device for grape planting. According to the method and device, bird repelling mode can be adjusted according to illumination conditions so as to drive away birds around grape trees and protect grapes from bird attack. The device is simple in structure and convenient to use.

The invention discloses a bird expelling apparatus for crop plantation. The bird expelling apparatus comprises a body; multiple support rods which are uniformly spaced and are vertically arranged in the body; multiple wind generating sets which are uniformly spaced on the body; multiple slide rails and multiple slide blocks in sliding connection with the slide rails; a driving apparatus which drives the multiple slide blocks to perform reciprocating movement on the multiple slide rails; a bird expelling generator; an illumination sensor; a laser lamp; a switch and a controller which controls the switch to turn on and turn off the laser lamp within certain time, controls the bird expelling generator to slide once in a reciprocating mode on the slide blocks within certain time and controls a buzzer to emit a buzzing sound according to a detection value of the illumination sensor. The invention discloses a method applying the bird expelling apparatus for crop plantation to expelling birds. The apparatus and the method are applied to expelling the birds around crops by adjusting bird expelling modes according to different illumination conditions, protect the crops from invasion by the birds, and also have the advantages of simple structure and convenient application.
