The working principle of the micro-irrigation device for interplanting crops in an orchard is that in a fruit garden, as shown in fig. 15, two suspension sleeves 1 are respectively fixed at a certain height position of a fruit tree trunk through upper flange seats 33 through bolts, then two rain collectors 15 are fixed at a certain height position of the fruit tree trunk through lower flange seats 18 on the rain collectors in the same mode, and the vertical distance between the suspension sleeves 1 and the rain collectors 15 is determined according to the actual situation. In the rain collecting process, the weight of the weight 2 is adjusted to separate the floater 3 from the inner cavity rain collector cavity 21 of the rain collector 15, so that the floater 3 is not in a suspended state with the irrigation water surface in the rain collector 15. A person pulls a rope at the tail end of a manual operation rope 30, the manual operation rope 30 drives an operation rope 29 to move, the operation rope 29 drives a cross rod 8 connected with the operation rope 29 to move in a vertical plane, so that rain collecting pieces 5 connected with the cross rod 8 are driven to move, a plurality of rain collecting pieces 5 are driven by the manual operation rope 30 to drive the operation rope 29 to simultaneously move, so that the rain collecting pieces 5 are upwards contracted until bosses 28 on the rain collecting pieces 5 move to the outer circumferential surface of a filter screen 16, the outer circumferential surface of the filter screen 16 is fixed, when the bosses 28 on the rain collecting pieces 5 are in contact with the filter screen 16, the rain collecting pieces 5 cannot continuously move upwards to contract, so that the tail end of the manual operation rope 30 is fixed through a rope positioning piece 31, at the moment, a plurality of rain collecting piece collection integrated annular rain collectors can collect natural rainfall, and in the process of collecting the natural rainfall, the rainwater firstly descends to fan-shaped rain collecting piece 5, then flows to the bottom of rain collecting piece 5 along rain collecting piece, the boss 28 that sets up in rain collecting piece 5 bottom assembles the rainwater, the part of rainwater can be collected to boss 28, have certain height with filter screen 16, so when collecting at every turn, the rainwater carries out the precipitation of a period at the part that rain collecting piece 5 bottom boss 28 envelops at first, reduce the impurity content in the irrigation water that passes through filter screen 16, along with collecting the continuation of natural rainfall, when the natural rainfall that obtains reachs a quantitative, just can filter through filter screen 16 and get into in the rain collecting cavity 21 of rain collector 15 through filter screen hole 20. The collected natural rainfall is filtered by the filter screen 16, flows through the water inlet 22 and finally flows into the rain collecting cavity 21 of the rain collector 15, and the natural rainfall can be well collected for irrigation through the process.

After the natural rainfall is collected, the quantity and the weight of the weights 2 are adjusted according to the water demand of crops, so that the position of the float 3 is adjusted, the float 3 enters the cavity of the rain collector 15, when the float 3 enters the cavity of the rain collector 15, the float starts to apply irrigation water inside the rain collector 15 at a certain pressure, if the quantity and the weight of the weights are not adjusted, the rain collector 15 can provide the irrigation water with constant pressure, for the crops suitable for micro-sprinkling irrigation, a switch on a water supply pipe of the micro-sprinkling irrigation emitter 13 can be opened to carry out micro-sprinkling irrigation, for the crops suitable for the micro-irrigation, a water flow switch on the drip irrigation capillary 10 can be opened, the irrigation time can be determined manually, and the rain collector 15 provides the constant-pressure irrigation water in the whole process. Although the device adopts the rainwater filtering and lining process of the filter screen 16 and the rainwater collecting sheet 5, the irrigation water still contains a certain amount of impurities to block the drip irrigation emitter, and in practical application, a large-flow water dropper can be adopted to reduce the problem of blocking of the drip irrigation emitter. Because the irrigation water pressure that micro-sprinkling irrigation and drip irrigation needs is different, the accessible is adjusted and is hung the weight and the quantity of 2 on the sleeve 1, reaches the purpose of adjusting irrigation work water pressure. The method can also be used for interplanting crops, wherein one side of the device is positioned on the sunny side, the other side of the device is positioned on the shady side, the difference between the water demand and the evaporation and transpiration action of the crops on the two sides is large, and the water demand is different to a certain extent, so that one rain collector can be arranged on the sunny side, the other rain collector can be arranged on the shady side, and the two rain collectors respectively supply water in a differentiated mode to the two sides.

Under the condition of strong illumination, although branches and leaves of the fruit trees can play a role of shading to reduce transpiration, the unidirectional illumination causes the continuous illumination of the bottom of the fruit trees close to the sunny side, and the illumination is not too strong to the shady side due to the shielding of the branches and leaves of the fruit trees. In order to solve the problem, the device is provided with the inner sunshade net 12 and the outer sunshade net 6, when the illumination is stronger, the manual operation rope 30 is changed from a fixed state to a movable state from the rope positioning piece 31 by the manual operation at the tail end of the manual operation rope 30, at the moment, the mosquito dispeller 9 on the cross rod 8 applies an axial force to the inner movable ring 25 and the outer movable ring 24, so that the inner movable ring 25 and the outer movable ring 24 extrude the inner extension spring 17 and the outer extension spring 7, and the inner extension spring 17 and the outer extension spring 7 are in a compressed state, so that the inner sunshade net 12 and the outer sunshade net 6 on the device can be known not to be unfolded, and the device has no sunshade effect. When the sun is needed to be shaded, the rain collecting piece 5 and the parts on the rain collecting piece are changed from the contraction state in front to the expansion state under the action of gravity, the cross rod 8 on the rain collecting piece 5 is driven to be gradually changed from the inclination state to the horizontal state in the unfolding process of the rain collecting piece, when the cross bar 8 is changed to be in a horizontal state, the axial pressure applied to the inner and outer telescopic springs by the mosquito dispeller 9 is gradually reduced from large to small until the cross bar 8 is changed to be in the horizontal state, the axial pressure applied to the inner sanitary telescopic spring by the mosquito dispeller 9 is 0, in the process, the inner extension spring 17 and the outer extension spring 7 are changed from the compressed state to the extended state under the action of the self elastic force, and the inner sunshade net 12 and the outer sunshade net 6 connected with the inner extension spring move along the axial direction of the cross rod 8, in the process of the movement, the inner sunshade net 12 and the outer sunshade net 6 are gradually unfolded to achieve the sunshade effect. The sunshade process can be selectively carried out, both sides can be shaded, and one side can be singly shaded, so that the applicability is strong.
