[0024] In arid and semi-arid irrigated agricultural areas, polyethylene mulch film is commonly used in crop production. This technology can improve soil hydrothermal conditions during the seedling stage, promote early growth, and increase yield. Therefore, it is widely used in crop production in arid areas, especially in ridge-furrow planting systems, where mulch film has become one of the common supporting measures. However, existing mulch film technology has obvious defects in long-term application: (1) Polyethylene mulch film is difficult to degrade naturally in the soil. After years of continuous use, residual film is easily accumulated, which can lead to microplastic pollution and the presence of harmful substances such as plasticizers, posing risks to the soil ecological environment and the sustainable use of farmland. (2) Although mulch film is beneficial for early temperature increase and moisture retention, its technical effect relies heavily on external plastic materials, resulting in a heavy ecological burden, which is not in line with the development trend of green agriculture.

[0025] In response to the aforementioned deficiencies of existing technologies, existing related technologies include straw return to the field and straw surface mulching. Conventional straw return to the field generally adopts deep plowing or full-layer mixed burial methods. Although it can supplement organic matter, it also has the following disadvantages: (1) It affects the sowing quality, soil structure and seedling growth; (2) The straw buried deep is not tightly integrated with the corn ridge moisture retention system, making it difficult to form a stable and effective surface protective layer; (3) Although straw surface mulching has a certain moisture retention effect, it is easily affected by wind, irrigation erosion and human operations, resulting in uneven distribution and poor mulching stability. Under the conditions of irrigated ridge cultivation in arid areas, it is difficult to maintain a good effect for a long time.

[0026] This invention provides a crop planting method based on clover mulch. The method involves constructing a ridge-furrow planting system, which is a field structure consisting of alternating wide ridges and furrows. Crops are sown on the wide ridges of this system based on the crop sowing date, planting density, and cultivation regime. The sowing time and amount of clover are determined, and clover is sown accordingly. Irrigation and field management are conducted on the sown clover based on crop growth to form a mulch layer from seedling emergence to jointing stage. This mulch layer can be continuous or semi-continuous. Because this invention sows clover in the ridge-furrow planting system, creating a stable and continuously growing mulch layer, it replaces polyethylene mulch. Through the surface protection, rhizosphere ecological regulation, and biological nitrogen supply functions of the clover mulch, it achieves a comprehensive effect of moisture retention, stable yield, fertilization, and pollution reduction. Therefore, it effectively solves the problem of residual film accumulation and microplastic pollution associated with existing polyethylene mulch technologies.

[0027] Exemplary method: like Figure 1 As shown, the crop cultivation method based on clover live mulch includes: Step S100: Construct a ridge-furrow planting system, wherein the ridge-furrow planting system is a field surface structure consisting of alternating wide ridges and furrows.

[0028] On level, well-moistened farmland awaiting planting, according to pre-set planting specifications, ridge-making operations are performed to alternately construct raised wide ridges and recessed furrows in the field. This creates a continuous and orderly alternating pattern of wide ridges and furrows along the planting direction, forming a undulating, ridge-furrow composite field surface. The wide ridges serve as the main planting zone for crops, with flat tops and regular walls, providing ample space for planting and soil moisture retention. The alternating furrows act as water channels, water storage areas, and ventilation and light penetration zones, catching irrigation water and natural rainfall, mitigating water and fertilizer loss, and preventing waterlogging and root rot. By using the above-mentioned land preparation and ridging methods, a wide-ridge-furrow alternating ridge-furrow planting system with stable structure, clear ridge and furrow distinction, and suitable for irrigation operations in arid areas can be constructed. This system can effectively meet the needs of moisture retention and yield increase in maize cultivation in arid and semi-arid areas, and provide a regular field basic structure for subsequent field mulching, sowing, and water and fertilizer management.

[0029] The dimensions of the ridges and furrows in a ridge-furrow planting system can be determined based on the crop being planted. Crops that are primarily grown in arid regions, suitable for ridge planting, and prefer well-aerated, moisture-retentive growing environments include sorghum, corn, and sunflowers.

[0030] like Figure 1 As shown, the method includes: Step S200: Sow the crop on the wide ridges of the furrow planting system based on the crop sowing date, planting density and cultivation system.

[0031] After the ridge-furrow system is constructed, standardized ridge sowing operations are carried out in conjunction with the actual sowing date of the crop, appropriate planting density, and regional cultivation system. Based on local climate conditions, accumulated temperature characteristics, and crop growth characteristics, the optimal sowing period is selected to avoid the impact of adverse weather conditions such as low temperatures and spring drought on crop emergence. Simultaneously, based on crop variety characteristics, soil fertility levels, and field production needs, reasonable plant spacing, row spacing, and seedling density per acre are set to determine standardized planting density. Strictly adhering to the established regional crop rotation, continuous cropping, or conservation cultivation system requirements, mechanized or manual sowing operations are completed on regular wide ridges. Crop seeds are evenly sown within the wide ridge planting layer, ensuring consistent sowing depth, uniform seed distribution, and tight soil covering. This achieves standardized ridge sowing with appropriate sowing date, reasonable density, and suitable cultivation system, ensuring uniform crop emergence and a reasonable plant population structure. It fully utilizes the advantages of the wide ridge-furrow system in moisture retention, aeration, and water conduction, laying a good foundation for robust crop growth during the seedling stage.

[0032] like Figure 1 As shown, the method includes: Step S300: Obtain the sowing time and amount of clover, and sow the clover according to the sowing time and amount.

[0033] After sowing crops, determine the sowing time and quantity of clover based on their growth needs and vigor. Within the determined sowing time, take a sufficient quantity of clover seeds according to the predetermined sowing amount and evenly sow them onto the soil surface of the planting area using standardized sowing methods, strictly matching the preset sowing quantity to complete the quantitative sowing operation. After sowing, perform shallow covering with soil and moderate compaction to retain moisture, ensuring close contact between the seeds and soil, guaranteeing timely and uniform clover emergence and the formation of a stable surface vegetation cover.

[0034] Optionally, the sowing time of clover is determined by the sowing time and growth of the crop. The sowing time of clover includes: using the sowing time of the crop as the sowing time of clover, or using the sowing time of the crop after emergence as the sowing time of clover, so as to reduce the competition between clover and crop seedlings.

[0035] Optionally, clover may be sown on the surface of the wide ridge or in the shallow area near the ridge surface, depending on the sowing time and the sowing amount.

[0036] like Figure 1 As shown, the method includes: Step S400: Irrigate and manage the clover after sowing according to the growth of the crops to form a covering layer from the seedling stage to the jointing stage of the crops. The covering layer is a continuous covering layer or a semi-continuous covering layer.

[0037] After sowing, the growth of clover in the field is monitored in real time. Based on soil moisture, climate conditions, and crop growth progress, targeted irrigation and routine field management are implemented. Irrigation is carried out appropriately and at the right time according to the water requirements of clover at different growth stages to ensure normal tillering and creeping growth of clover seedlings. Simultaneously, field management measures such as weeding and loosening the topsoil optimize the clover growth environment and regulate its growth rate and population density. Continuous and meticulous field management ensures that the clover growth cycle precisely matches the crop growth cycle, guaranteeing a stable vegetation cover layer on the field surface during the seedling to jointing stages of the crop without excessively affecting the normal growth of the crop. This cover layer can be configured as a continuous full-coverage structure or a semi-continuous intermittent cover structure according to field cultivation needs, thereby achieving effective coverage and protection of the farmland surface soil.

[0038] Optionally, irrigation can be carried out according to the irrigation system of the crop planting area, combined with conventional base fertilizer and topdressing management to complete the nutrient supply throughout the entire growth period. Because clover mulch can continuously improve the soil surface environment during its growth process and enhance the soil nutrient supply potential in the middle and later stages of crop growth, it is beneficial to the recovery of crop growth and yield formation in the later stages. At the same time, clover mulch helps to improve the biological activity of the topsoil, promotes the enrichment of microorganisms related to pollutant degradation, and thus enhances the degradation potential of pollutants from the mulch film.

[0039] Optionally, field management of the clover mulch can be implemented based on the growth of the clover community and the growth requirements of maize. Field management of clover includes one or more of the following: mowing, burying, and partial clearing. This reduces clover coverage, controls its growth intensity, and avoids excessive competition with crops during the seedling or critical growth stages. This step helps to balance the moisture retention and ecological regulation functions of clover mulch with the crop's requirements for light, water, and nutrients for yield formation.

[0040] Alternatively, after the crops mature and are harvested, the clover residues and roots can be retained or incorporated into the soil for further utilization as green manure or a source of organic matter.

[0041] like Figure 2 As shown, taking corn as an example: Before sowing, the land is prepared to construct a ridge-furrow planting system suitable for irrigated maize cultivation in arid areas.

[0042] In one implementation, if the crop is corn, in the ridge-furrow planting system, the width of the wide ridge is 60–80 cm, the height of the wide ridge is 8–15 cm, and the width of the furrow is 30–50 cm. This structure facilitates corn sowing, irrigation water distribution, and the establishment of a clover cover layer, while also making it easier to form a relatively stable living cover space on the ridge surface.

[0043] Sow according to the local conventional sowing date, planting density, and cultivation system for maize. It is preferable to complete maize sowing during the suitable spring sowing period to allow the main crop to grow preferentially and establish a population base. Prioritizing the growth space of the main maize crop is beneficial for the subsequent establishment of a relatively harmonious symbiotic relationship between clover mulch and maize.

[0044] Determine the sowing time and quantity of clover, and sow clover seeds according to the time and quantity to form a low, living cover layer. The sowing time of clover is determined by the sowing time and growth status of corn, including either using the corn sowing time as the clover sowing time or using the time after corn emergence and stabilization as the clover sowing time. Preferably, clover is sown between corn emergence and the 3-leaf stage, allowing corn to preferentially establish its root system and community structure in the early stages, after which the clover gradually forms a living cover layer. This method is more suitable for areas with early low temperatures, sensitive seedling competition, or high requirements for early corn growth, and helps improve the stability of technology implementation.

[0045] In one implementation, when the crop is corn, obtaining the clover seeding rate includes: obtaining the crop's seeding environment, which represents the evaporation intensity, soil texture, irrigation conditions, and target coverage of the crop planting site; and determining the clover seeding rate based on the seeding environment, wherein the seeding rate is 90–150 kg / ha. Preferably, it is 100–130 kg / ha, more preferably about 120 kg / ha.

[0046] In one implementation, when the crop is sown in a region with high evaporation, the sowing rate of clover is determined to be 120–150 kg / ha. Specifically, in areas with high evaporation, strong winds, and rapid surface water loss, the sowing rate of clover can be appropriately increased or its coverage period extended to enhance surface protection. The sowing rate of clover can be adjusted to 120–150 kg / ha, and a high coverage level can be maintained during the mid-to-late stages of maize growth to improve the continuity of the cover layer and its ability to retain moisture. This implementation plan is beneficial for enhancing the surface shading effect, reducing evaporation loss, improving the microenvironment of the topsoil, and further enhancing the soil ecological regulation function.

[0047] Clover is ideally sown on the surface of the ridges so that after germination it primarily covers the bare areas of the ridges without significantly affecting the maize planting strip. By establishing a living mulch layer on the ridges, the exposed surface area can be reduced, evaporation can be decreased, and biomass and root exudates can be continuously introduced into the soil during the growth process.

[0048] After clover sowing, conventional irrigation and field management promote clover emergence, transplanting, and community establishment, gradually forming a continuous or semi-continuous cover layer during the maize growth period. The clover cover layer is ideally formed gradually from the maize seedling stage to the jointing stage, maintaining a certain cover intensity in the mid-to-late stages of maize growth. This cover layer can, on the one hand, inhibit surface evaporation and buffer changes in surface soil temperature and humidity; on the other hand, it can improve the rhizosphere microecological environment, enhance soil biological activity, and provide a more suitable environment for microorganisms related to pollutant degradation.

[0049] Based on the growth of the clover community and the growth needs of maize, the clover mulch layer should be appropriately regulated. If necessary, methods such as mowing, burying, partial clearing, or reducing the mulch density can be used to control its growth intensity and avoid excessive competition with the main maize crop during the seedling or critical growth stages. This step helps to balance the moisture retention and ecological regulation functions of clover mulch with the maize's requirements for light, water, and nutrients for yield formation.

[0050] Water and fertilizer management is implemented for corn and clover, supplying nutrients to both plants throughout their growth cycle through irrigation, basal fertilizer, and topdressing. Because live clover mulch continuously improves the topsoil environment during growth and enhances soil nutrient supply potential in the mid-to-late stages of corn growth, it is beneficial for corn's later growth recovery and yield formation. Simultaneously, clover mulch enhances the biological activity of the topsoil, promotes the accumulation of microorganisms related to pollutant degradation, and thus improves the degradation potential of pollutants from the mulch film.

[0051] During the period when corn and clover grow together, pest, disease, and weed control and field management should be carried out in accordance with conventional methods. The focus of management is to maintain an appropriate coverage of the clover mulch layer, so that it can play its role in mulching and ecological regulation without excessively affecting the normal growth of corn. After the corn matures, it should be harvested in accordance with conventional methods. After harvesting, the clover residues and roots on the ground can be retained or turned into the soil for further utilization as green manure or a source of organic matter.

[0052] This method, by constructing a living clover cover layer, can not only reduce surface evaporation, improve the soil microenvironment and enhance the subsequent nitrogen supply, but also facilitate the enrichment of pollutant degradation-related microorganisms, enhance the degradation potential of pollutants from the mulch film, and reduce the environmental risks posed by residual film, microplastics and related plasticizers.

[0053] Compared with existing technologies, the present invention has the following overall technical effects: maintaining good corn yield and water use efficiency while reducing or replacing the use of polyethylene mulch film; improving soil physicochemical properties and rhizosphere microecological environment; enhancing soil fertility through live mulching and biological nitrogen supply; increasing the degradation potential of pollutants from mulch film and reducing the risk of farmland pollution; and forming an integrated green cultivation technology that combines agricultural production and ecological restoration functions.
