Description

Technical Field

[0001] This invention relates to the field of silage planting technology, and more specifically, to a fully mechanized silage planting method that synergistically improves both yield and quality. Background Technology

[0002] The shortage of feed grains has led to a serious conflict between grain and feed, severely impacting food security. The "grain-to-feed" initiative has effectively addressed the issue of forage yield. While corn, a core silage crop, has a high yield, its low crude protein content results in poor forage quality. Increasing forage protein content has become the final step towards high-quality development of the forage industry. Labrador soybean, a high-quality legume forage, is rich in crude protein but has a low yield. In the semi-arid Loess Plateau region, located in the agro-pastoral transition zone, influenced by climate, soil, and traditional production practices, corn forage is primarily planted using the full-film double-ridge furrow planting technique.

[0003] Currently, this technology faces three main problems: First, the density is unreasonable, as feed corn production simply replicates the density of grain corn, resulting in low and unstable yields and low efficiency in the utilization of water, soil, and fertilizer resources. Second, field operations rely on manual labor, leading to high costs and low economic benefits, with a low level of full mechanization, which restricts large-scale production. Third, there is a lack of mechanized production technologies that coordinate yield and quality and integrate agricultural machinery with agronomy, thus affecting the high-quality development of the feed corn industry. Therefore, a fully mechanized planting method for silage forage that synergistically improves yield and quality is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a fully mechanized planting method for silage forage that synergistically improves both yield and quality, in order to solve the main problems existing in regional forage production. This technology can effectively improve the yield and quality of dryland forage, create a green forage production model, and play an important role in improving the quality and efficiency of regional agricultural development.

[0005] This invention, based on full-film double-ridge furrow sowing of maize, innovatively proposes to improve forage production capacity and the level of mechanized production by selecting high-quality, high-yield, and dense-planting-tolerant maize varieties and high-yield, high-quality, and drought-resistant Laba bean varieties. It proposes to change the monoculture of forage maize to a mixed cropping system of dense-planting forage maize and Laba bean. This approach increases forage maize yield through dense planting, increases protein yield through intercropping with Laba bean, achieves full mechanization through machinery integration, and combines land use with nutrient utilization through the application of organic fertilizer to increase carbon and Laba bean nitrogen fixation. This technology has significant potential for widespread application in arid and semi-arid regions and is of great practical significance for the high-quality and sustainable production of dryland forage and for crop-livestock cycles.

[0006] To achieve the aforementioned objectives, this invention provides the following technical solution: a fully mechanized planting method for silage forage that synergistically improves both yield and quality, characterized by comprising the following steps: Step 1: Variety selection: Select the forage corn variety Xianyu 1225 and the Laba bean variety Rungao (purple flower black seed type); among them, Xianyu 1225 is a mid-to-late maturing dual-purpose corn for grain and forage, with strong adaptability, drought and barren soil tolerance, and resistance to red spider mites and aphids in the later stage; Rungao (purple flower black seed type) Laba bean is drought and barren soil tolerance, with a crude protein content of 18% to 22% and strong nitrogen fixation ability; Step 2: Fertilization and Land Preparation: After the soil thaws from late March to early April, use a residual film harvester to remove the previous season's plastic film and remove it from the farmland. The residual film is used for trade-in or recycling. Then, apply pure nitrogen at a rate of 200 kg·hm². -2 150 kg·hm of pure P2O5 -2 Commercial organic fertilizer 22.5-30 t·hm -2 Apply nitrogen fertilizer, phosphorus fertilizer and organic fertilizer evenly, with urea containing N > 46% and superphosphate containing P2O5 > 16% as the nitrogen fertilizer; use a vertical deep rotary tiller to plow and prepare the land to a depth of 25-30cm, break up the plow pan, and mix the fertilizer into the soil at the same time to ensure that the plot is flat and the soil is fine and compact. Step 3: Ridging and Mulching: A full-film double-ridge furrow planting and mulching machine for corn is used to complete the ridge-raising and mulching operations in one go; the ridges are arranged with alternating large and small ridges, with the large ridges being 15 cm high and 70 cm wide, and the small ridges being 20 cm high and 40 cm wide, with a planting width of 110 cm; the mulching uses a thickened high-strength white polyethylene film with a width of 120 cm and a thickness of 0.015 mm to achieve full surface coverage, and at the same time, two holes are mechanically punched every 1 m in the furrows to ensure effective infiltration of rainwater; Step 4: Sowing: Mechanized sowing is carried out using a rolling hill seeder. Specifically, Laba soybeans are sown around April 15th, ensuring the soil temperature remains stable above 5℃ for 5 consecutive days during the sowing period, at a rate of 75,000 plants per hectare. -2 Sow at a density of 25 cm at the edge of the raised beds, with a sowing depth of 3–4 cm; forage corn should be sown around May 1st, ensuring the soil temperature remains stable above 10℃ for 5 consecutive days, at a rate of 75,000 plants per hectare. -2 Sow at a density of 4-5 cm in the furrows, with the same plant spacing as the leptomeria; when sowing, the leptomeria and corn planting holes are aligned, with the leptomeria planted close to the edge of the ridge, naturally twining around the corn and growing upwards, forming a complementary spatial niche. Step 5: Field management: During the growing season, manually remove weeds and control pests and diseases. Other management measures shall be carried out in accordance with the conventional management standards for high-yield maize fields. Step 6: Harvesting: At the late milk stage, 100-110 days after sowing forage corn, use forage corn harvesting machinery to harvest the silage corn and larvae in one go, leaving the stubble for mixed harvesting. This planting method is suitable for semi-arid rain-fed agricultural areas of the Loess Plateau with an annual precipitation of 350-500 mm or irrigated areas with supplementary irrigation.

[0007] As a preferred technical solution of the present invention, in step 2, all fertilizers are applied as base fertilizers in one deep application. The vertical deep rotary tillage machine realizes the mechanized integrated operation of fertilization and land preparation, effectively improving soil fertility, realizing soil improvement and fertilization, and enhancing the ability of planting and breeding integration.

[0008] As a preferred technical solution of the present invention, the use of thickened high-strength white polyethylene mulch film in step 3 can improve the level and efficiency of mechanized recycling of mulch film, reduce residual film pollution, and balance ecological benefits and production costs.

[0009] As a preferred technical solution of the present invention, in step 3, the full-film double-ridge furrow sowing technology reduces ineffective evaporation of soil moisture and improves crop water use efficiency by collecting rainwater in furrows and ridges and covering the entire surface to suppress evaporation, retain moisture and increase temperature, thus adapting to the planting needs of semi-arid areas.

[0010] As a preferred embodiment of the present invention, in step 4, the planting density of both Laba soybean and forage corn is 75,000 plants per hectare. -2 This density configuration achieves the integration of agricultural machinery and agronomy, ensuring both growth space for the two crops and increasing overall yield.

[0011] As a preferred technical solution of the present invention, in step 4, the sowing time difference between Laba soybean and feed corn matches their respective growth characteristics of preferring warm and cool temperatures, while making efficient use of the growing season and light and temperature resources, avoiding conflicts in the growth period, and making full use of light, heat, water and fertilizer resources.

[0012] As a preferred technical solution of the present invention, in step 4, the layout of planting Laba soybeans on the edge of the ridge and forage corn in the furrow eliminates the need for manual winding of the vines, enabling Laba soybeans to precisely twine around the corn for growth and improving planting efficiency.

[0013] As a preferred technical solution of the present invention, in step 6, the selection of the harvest time at the end of the milk stage optimizes the yield and crude protein content of the mixed forage, thereby achieving a synergistic improvement in yield and quality.

[0014] As a preferred technical solution of the present invention, steps 2 to 4 all adopt mechanized operations, reducing manual input, lowering labor costs, improving planting efficiency, and realizing fully mechanized planting.

[0015] As a preferred technical solution of the present invention, by intercropping Laba soybeans with forage corn, the nitrogen-fixing and soil-nourishing characteristics of leguminous crops are utilized to solve the problem of soil fertility depletion caused by monoculture, realize the combination of arable land use and conservation, and improve the sustainability of planting.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: The planting method of this invention can improve the yield and quality of forage. This invention employs a full-film double-ridge furrow sowing method for intercropping forage maize and Labrador soybeans, utilizing the complementary properties of high-yield forage maize and protein-enhancing Labrador soybeans. This satisfies the differentiated needs of the two crops for light, heat, water, and fertilizer resources, as well as the nitrogen-fixing and soil-nourishing characteristics of leguminous crops. It couples the synergistic effect of high-density planting of forage maize in dryland areas to increase yield and improve the quality of leguminous crops. This achieves intensive and efficient utilization of limited water resources in semi-arid regions, synergistic improvement of forage yield and crude protein content, and efficient recycling of mulch film. It changes the problems of unstable yield and low quality in traditional monoculture of forage maize, as well as the reliance on manual labor and low resource utilization in intercropping models. It alleviates the resource constraints of forage production in dryland areas. Through the complementary relationship between Labrador soybeans and forage maize, it helps solve problems such as soil fertility depletion and unreasonable population structure caused by monoculture.

[0017] The method of this invention is applicable to semi-arid rainfed agricultural areas of the Loess Plateau with an average annual precipitation of 350-500 mm, or irrigated areas with supplementary irrigation conditions. It is particularly suitable for areas with developed planting and animal husbandry industries, but low and unstable corn yields, or high-yield forage corn but low crude protein content, and areas with low levels of mechanization. The planting width of the full-film double-ridge furrow is 110 cm. This width is designed based on the full-film double-ridge furrow planting technology in dryland areas and existing agricultural machinery. Two rows of forage corn and two rows of Laba soybeans are sown in each planting strip. This mixed cropping combination allows Laba soybeans to climb and grow independently with corn as a support, while also creating a three-dimensional community structure with good ventilation and light penetration in the field. This ensures a stable yield of forage corn and increases the crude protein content of the mixed forage through nitrogen fixation by leguminous crops, achieving a synergistic improvement in forage yield and quality and a combination of arable land use and animal husbandry.

[0036] Methods for determining and calculating relevant indicators.

[0037] Yield determination: At the late milk stage of forage corn, all fresh forage corn and lappa beans from each plot were weighed and their moisture content was measured to calculate the fresh and dry forage yields of forage corn and lappa beans. Then, three forage corn and lappa beans were selected for each organ to be separated, blanched in an oven at 105℃ for 30 minutes, and then dried at 75℃ to constant weight. The dry matter accumulation of each organ of a single corn and lappa bean plant was measured to calculate the crude protein yield.

[0038] Crude protein yield determination: The crude protein content of the mixed forage was determined by the Kjeldahl method, and the crude protein yield was calculated in combination with the hay yield.

[0039] Soil moisture content determination: Before sowing and after harvest, soil moisture content was measured at the middle of the 2nd, 3rd, and 4th films in each plot. Three points were selected and soil samples were taken with a soil drill. The samples were mixed and placed in an aluminum box. The soil moisture content was determined by drying method. The measurement layers were 0~5, 5~10, 10~30, 30~50, 50~80, 80~110, 110~140, 140~170, and 170~200 cm, for a total of 9 layers.

[0040] The calculation formula for soil drying method is as follows: In the formula, W1 is the fresh weight of the soil (g) and W2 is the dry weight of the soil (g).

[0041] The formula for calculating soil water storage is: In the formula: W is the soil water storage capacity (mm); h is the soil depth (cm); denoted as soil bulk density (g·cm⁻³); w represents soil moisture content (%); and 10 is the conversion factor.

[0042] Water consumption during the growing season: Water consumption during the forage growing season was estimated using the water balance method. The calculation formula is as follows: In the formula, P is the precipitation during the growing season (mm); I is the irrigation water during the growing season (mm); G is the groundwater recharge (mm); R is the surface runoff (mm); D is the deep infiltration (mm); ΔW is the change in soil water storage from 0 to 200 cm. W = Pre-sowing soil water storage - Harvest soil water storage (mm); Since the experiment was conducted in a dryland rainfed agricultural area, the experimental site was flat and surrounded by ridges to prevent runoff, and the groundwater was deep with no irrigation. Therefore, the applicable formula for calculating crop water consumption in this experiment is: Water use efficiency (WUE, kg·hm) -2 ·mm -1 The formula for calculating ) is: In the formula, Y represents the total fresh grass yield (kg·hm). -2 ); ET represents the water consumption during the forage growth period.

Compared with Comparative Example 2, Example 1 showed a 12.8% increase in fresh grass yield, a 6.8% increase in hay yield, an 18.8% increase in crude protein yield, and an 8.9% increase in water use efficiency. Compared with Comparative Example 3, Example 1 showed a 37.4% increase in fresh grass yield, a 29.9% increase in hay yield, a 42.6% increase in crude protein yield, and a 36% increase in water use efficiency. 1%; Example 1 compared to Comparative Example 4: Fresh grass yield increased by 32.2%, hay yield increased by 9.0%, crude protein yield increased by 2.2%, and water use efficiency increased by 37.3%; Example 1 compared to Comparative Example 5: Fresh grass yield increased by 24.8%, hay yield increased by 21.3%, crude protein yield increased by 8.1%, and water use efficiency increased by 26.7%; Example 1 compared to Comparative Example 6: Fresh grass yield increased by 0.7%, hay yield increased by 2.4%, crude protein yield increased by 5.5%, and water use efficiency increased by 1.6%.
