Description

Technical Field

[0001] The utility model belongs to the technical field of orchard grass planting, and particularly relates to a Stenotaphrum secundatum planting structure under fruit trees in an orchard. Background Technique

[0002] Orchard grass planting cultivation refers to an orchard soil management system in which herbaceous plants are artificially planted as ground cover in the rows or the whole orchard between fruit trees, making full use of the diversity and stability of the orchard ecosystem to improve the microclimate in the orchard and improve the soil structure. In-depth research on fruit tree cultivation and management techniques and the promotion of agricultural modernization have practical significance for improving the production efficiency of fruit planting. As a modern green and healthy soil management method, the key to the successful application of grass planting cultivation lies in the selection of grass seeds. Therefore, in-depth research on the characteristics of grass seeds, the adaptability of grass seeds, and the mechanism of water and nutrient competition between fruit trees and grass has very important practical significance for promoting the transition of grass planting cultivation from theoretical research to practice, improving the orchard environment, promoting fruit tree production, and increasing economic benefits.

[0003] Stenotaphrum secundatum is a perennial herb of the genus Stenotaphrum in the Gramineae family, which has the advantages of fast reproduction and trampling resistance. Once the community is formed, it is difficult for other grass seeds to invade. Its management requirements are relatively extensive and the maintenance cost is relatively low. It is usually used as a lawn grass, but there is no report on the application of Stenotaphrum secundatum in the field of grass planting under fruit trees in an orchard. The environment under fruit trees in an orchard is different from lawn greening. The former is restricted by factors such as the shaded environment, soil conditions, and fruit tree cultivation and management, resulting in the difficulty of the survival of Stenotaphrum secundatum cultivated by ordinary cultivation methods. Although the method of burying stolons in trenches improves the survival rate of creeping herbs to a certain extent, this method requires shallow trenches. However, the water retention capacity of orchard soil is poor, and the soil covering the shallow trenches is easily washed and displaced after irrigation in the orchard. Once the stolons are exposed, they are very likely to die. If precise water supply is carried out specifically for Stenotaphrum secundatum, the relevant facilities and labor costs will increase greatly, which is not suitable for orchards with economic output as the main indicator. Therefore, it is very necessary to develop a Stenotaphrum secundatum planting structure under fruit trees in an orchard that can solve the above problems. Content of the Utility Model

[0004] Based on the above technical problems, the purpose of the utility model is to provide an orchard planting structure that can promote the survival of Stenotaphrum secundatum under fruit trees in an orchard.

[0005] The purpose of the present utility model is achieved as follows. It includes a planting groove, placement holes, a water retention agent layer, a soil covering layer, and a soil pressing device. A number of placement holes are provided at the bottom of the planting groove. A water retention agent layer is provided in the placement holes. The soil covering layer is located in the planting groove and is above the water retention agent layer. The soil pressing device includes insertion rods, fixed crossbars, sliding sleeves, and pressing strips. There are two fixed crossbars arranged in parallel. Insertion rods are longitudinally provided at the bottoms of both ends of the fixed crossbars. A number of sliding sleeves are sleeved on the fixed crossbars. A pressing strip is connected between the sliding sleeves of the two fixed crossbars. The insertion rods are inserted into the soil layers on both sides of the planting groove. The fixed crossbars are distributed on the ground surfaces on both sides of the planting groove along the length direction of the planting groove. The pressing strip presses the soil covering layer.

[0006] The water retention agent in the water retention agent layer is superabsorbent resin particles well-known to those skilled in the art.

[0007] For the sliding sleeve, there is not a large sliding gap between it and the fixed crossbar, but rather a large frictional force between the two, that is, there is a certain sliding resistance. At the same time, when a worker holds the sliding sleeve and exerts force, the sliding sleeve can also slide on the fixed crossbar; Operation essentials: Insert the insertion rods into the soil layer, and make the pressing strip closely adhere to and press the corresponding soil covering layer.

[0008] Preferably, there are multiple planting grooves distributed under the fruit trees in the orchard, and the planting grooves are parallel to each other; The specific number of planting grooves is flexibly selected according to the grass-growing area.

[0009] Preferably, the depth of the planting groove is 5 cm to 10 cm, and the width is 10 cm.

[0010] Preferably, the placement holes are distributed in a plum blossom shape.

[0011] Preferably, the number of pressing strips is 5 to 7, and there is a spacing between adjacent pressing strips.

[0012] Preferably, the width of the pressing strip is 1 cm to 2 cm.

[0013] The beneficial effects of the present utility model: The planting groove of the planting structure of the present utility model is used to place the jointed and leafy stem segments of Stenotaphrum secundatum. Through the reasonable structure of the planting groove and in cooperation with the soil covering layer and the water retention agent layer, it can effectively ensure the survival of Stenotaphrum secundatum cultivated under the fruit trees in the orchard; The soil pressing device plays a role in fixing the soil covering layer, especially suitable for fixing the soil covering layer in a planting groove with a relatively shallow depth, ensuring that the joints of the Stenotaphrum secundatum stem segments are covered by the soil covering layer and preventing the soil covering layer from being washed away after irrigation; The position of the pressing strip of the soil pressing device can be adjusted, and the gap between the pressing strips will not block the leaves from protruding, without affecting the normal growth of Stenotaphrum secundatum. Moreover, the soil pressing device has a simple structure, is easy to process, has a low cost, is convenient to use, and can be reused. Description of the Drawings
