When the sunshade net 51 is required to be covered above the top of the crown of the transplanted nursery stock, the height position of the adjusting square ring 20 on the corresponding supporting square rod 18 in the four upright mechanism 17 is adjusted and fixed according to the height of the nursery stock required to be shaded; four deeper pile holes are formed around the tree; the four upright rod mechanisms 17 are uniformly and vertically fixed on the periphery of the nursery stock needing sun shading in the circumferential direction in a mode that the lower ends of the supporting square rods 18 in the four upright rod mechanisms 17 are fixed in corresponding pile holes, and the adjusting square rings 20 in the four upright rod mechanisms 17 are higher than the top of a crown; then, after four corners of the sunshade net 51 are respectively tied on the net pulling plates 5 in the four floating mechanisms 1 through ropes, hydrogen bulbs 12 in the four floating mechanisms 1 are filled with hydrogen; then, the string B15 in the four floating mechanisms 1 is pulled by hand, the four hydrogen balloons 12 are sequentially and gradually released upwards, the four hydrogen balloons 12 drive the sunshade net 51 to move to a position higher than the top of the crown, the lower end of the cutting 7 in the floating mechanism 1 is higher than the top end of the horn tube 27 in the vertical rod mechanism 17, and the four hydrogen balloons 12 respectively drive the corresponding fixing block A9, the guide round block 6, the cutting 7 and the positioning block A2 to synchronously move through the corresponding string A14 and the stepped round block 11; then two persons pull the strings B15 in the four floating mechanisms 1 to move the sunshade net 51 right above the top of the tree crown of the nursery stock, and the four floating mechanisms 1 respectively correspond to the four upright mechanisms 17.

Then fixing the position of the sunshade net 51 to prevent the sunshade net 51 from floating left and right above the bottom of the crown under the action of wind; firstly, the tail ends of the strings C16 in the four floating mechanisms 1 respectively penetrate through the guide holes 39 on the positioning plates 37 and the slide grooves C41 on the positioning blocks B40 in the corresponding vertical rod mechanisms 17 from top to bottom in sequence and are tied on the fixing plates 33 on the side surfaces of the corresponding supporting square rods 18, and then the cranks 31 in the four vertical rod mechanisms 17 are respectively shaken; since the operation flow of the four vertical rod mechanisms 17 is completely the same, the operation of only one vertical rod mechanism 17 will be described, and the operation flow of the vertical rod mechanism 17 is as follows:

the crank 31 is shaken, the crank 31 drives the winding wheel 30 to rotate, and the winding wheel 30 drives the sliding sleeve 34 and all components arranged on the sliding sleeve 34 to synchronously move upwards along the supporting square rod 18 through the thin steel wire 29 and the fixed block B35; during the upward movement of the positioning plate 37 with the sliding sleeve 34, the guide hole 39 on the positioning plate 37 guides the string C16 passing through it gradually to the vertical state; the string C16 gradually guided to the vertical state by the guide hole 39 drives the positioning block A2, the guide round block 6, the fixing block A9, the inserting strip 7, the step round block 11, the string A14 and the hydrogen balloon 12 in the corresponding floating mechanism 1 to synchronously swing to the right above the bell mouth of the horn cylinder 27; when the sliding sleeve 34 drives all the components mounted thereon to move upwards to the limit position along the supporting square rod 18, the string C16 in the corresponding floating mechanism 1 is basically in a vertical state as a whole, and the string C16 drives the guiding round block 6, the fixing block a9 and the inserting bar 7 to reach the position right above the bell mouth above the horn 27 and within the range of the bell mouth through the positioning block a 2.
