Problems solved by technology

Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the problem of insufficient natural rainfall.
Traditional farmland irrigation is usually flood irrigation, which is a serious waste of water resources and requires more human assistance, so it is gradually replaced by more advanced and efficient irrigation technologies such as sprinkler irrigation and underground irrigation. Sprinkler irrigation is laid on the surface The advanced pipeline system sprays water from the nozzle into the air for irrigation. Underground irrigation supplies water through the seepage pipe network buried below the field surface, and then seeps out through the holes in the pipe wall. Although this advanced irrigation method has good irrigation effect, it is expensive The cost is relatively high, and it is only suitable for some high-yield economic crops, which is not conducive to comprehensive promotion
[0004] It can be seen that there are some problems in the existing corn stalk returning and farmland irrigation, the limitations are relatively strong, and it is difficult to fully promote it. Therefore, it is necessary to change the form and method of returning corn stalks to the field, so as to not only increase soil fertility, but also improve soil fertility. Can assist farmland irrigation and reduce irrigation costs

Embodiment 1

[0054] Embodiment one, refer to the description attached Figure 1-22 A method for returning corn stalks to the field for underground irrigation by mixing crushed corn stalks with soil, humidifying and extruding them into composite pipes, comprising corn stalks, soil, and water, comprising the following steps:

[0055] Step 1. Preparation of corn stalk fiber: After the corn stalk is naturally air-dried, it is crushed into straw debris with a crushing device;

[0056] Step 2. Preparation of materials for making composite pipes: Put a certain proportion of soil and straw debris into the stirring device for stirring and mixing, and continuously add water to the stirring device to increase the humidity. The combination of water, straw and soil can form viscosity higher mixture until a moist soil-straw mixture is formed;

[0057] Step 3. Making composite pipes: Put the moist soil straw mixture into the pipe extrusion device to make composite pipes. The side walls of this composite...

Embodiment 2

[0067] Embodiment two, refer to the appended Figure 3-22 , an integrated pipe-making and field-returning equipment, relying on this equipment to complete the specific implementation of steps 1 to 4 in Embodiment 1, the equipment includes a cutter shaft and an auger installed in the housing bracket, and one end of the housing bracket The installed secondary crushing conveying device, the power transmission device installed at the rear of the shell support, the equipment also includes a ditching device installed in the middle of the front end of the shell support, and a conical extrusion device installed in the middle of the upper end faces between the shells , the middle of the rear end of the shell bracket is provided with a hitch;

[0068] The cutter shaft and the auger are rotated side by side and connected in the housing bracket, the two ends of the auger and the cutter shaft are equipped with pulleys, the auger is located at the front end of the housing bracket, and the o...

Abstract

The invention relates to a field returning method for crushing corn straws, mixing crushed corn straws with soil, humidifying and extruding to form composite pipes for underground irrigation. A field returning method of a composite pipe for underground irrigation comprises the steps that smashed corn straw, soil and a mixed agent are mixed to form a humid soil and straw mixture, the humid soil and straw mixture is made into the composite pipe through an extrusion device, straw and soil in the composite pipe are tightly combined, and the decomposition speed of the straw can be increased; the composite pipe is deeply buried in the land; thoroughly decomposed straw in the composite pipe can directly act into deep soil, and the organic matter content of the deep soil is increased; the composite pipe buried in the ground surface is also used for farmland irrigation; a small gap can be formed between the stem scraps and the soil in the composite pipe; in the process that irrigation water enters from one end of the composite pipe and flows to the other end of the composite pipe, the irrigation water continuously seeps out from gaps at the stem scraps on the side wall of the composite pipe; the composite pipe forms an underground seepage pipe, and seepage irrigation water is absorbed and diffused through soil; therefore, the composite pipe solves the problem of limitation of returning the corn straws to the field, reduces the irrigation cost, and is suitable for comprehensive popularization.

Description

technical field [0001] The invention relates to the technical fields of straw returning to the field and agricultural irrigation, in particular to a field returning method in which corn straw is crushed and soil is mixed, humidified and extruded into a composite pipe for underground irrigation. Background technique [0002] Corn stalks are an important by-product in the process of corn planting. Every year, more than 700 million tons of various types of straws are produced in my country's agricultural production, and there are about 350 million tons of corn stalks. Corn stalks are rich in nitrogen, phosphorus and potassium nutrients, and are important in agricultural production. important nutrient resource. Corn straw returning plays a key role in improving soil fertility, improving soil structure, increasing soil carbon sink, and enriching soil microbial diversity. The existing method of returning corn stalks to the field is strongly affected by weather conditions. For exam...
