Description

Technical Field

[0001] This invention belongs to the field of root-oriented induction cultivation of fruit and vegetable plants, specifically a method for root-oriented induction cultivation of fruit and vegetable plants. Background Technology

[0002] The size of the root system's distribution area directly determines the plant's ability to absorb water and nutrients, as well as its disease and stress resistance, thus affecting yield and quality. Traditional fruit and vegetable cultivation methods often use one or two drip irrigation tapes for water and fertilizer supply, with planting ridges typically less than 70 cm wide. The water- and fertilizer-oriented growth characteristics of fruit and vegetable roots cause them to naturally concentrate in the soil near a single or double row of drip irrigation tapes. Combined with the limited ridge width, this restricts root growth, making it difficult to fully utilize nutrients and water in deeper and larger planting ridges. Consequently, the plant's disease resistance and drought stress resistance are poor. Furthermore, the traditionally laid drip irrigation tapes are generally close to the seedlings, and frequent, close-root watering and fertilization can severely damage the roots, leading to premature plant aging. Existing root-induction cultivation techniques often suffer from poorly designed induction schemes, cumbersome procedures, and limited root expansion, resulting in low soil space utilization. Summary of the Invention

[0003] This invention provides a root-oriented induction cultivation method for fruit and vegetable plants to overcome the deficiencies in the prior art.

[0004] This invention is achieved through the following technical solution: A method for directional root induction cultivation of fruit and vegetable plants includes the following steps: Step 1: Plant the plants by setting up planting ridges in a row-by-row pattern; Step 2: symmetrically lay multiple drip irrigation tapes along the planting ridges; Step 3: Create an orderly water gradient by starting from the inside out and activating it in stages; Step 4: Apply fertilizer in stages and zones with precise targeting.

[0005] As described above, in the root-oriented induction cultivation method for fruit and vegetable plants, the height of the planting ridge in step one is 25-35cm, the width of the planting ridge surface is 0.8-1.2m, and the fruit and vegetable plants are planted in the middle of the planting ridge.

[0006] As described above, in the root-oriented induction cultivation method for fruit and vegetable plants, five drip irrigation tapes are set in step two. One drip irrigation tape is set in the middle of the planting ridge where the fruit and vegetable plants are planted, and two drip irrigation tapes are set symmetrically on both sides.

[0007] In the above-described root-oriented cultivation method for fruit and vegetable plants, the interval between adjacent drip irrigation tapes in step two is 15-25cm.

[0008] As described above, the root-oriented induction cultivation method for fruit and vegetable plants includes the following steps in step three: during the seedling transplanting period, only the middle drip irrigation belt is opened; during the seedling establishment period, the middle drip irrigation belt is closed and the two adjacent drip irrigation belts are opened; from the fruit expansion period to the end of the planting period, the three middle drip irrigation belts are closed and the two outermost drip irrigation belts are opened.

[0009] The root-oriented induction cultivation method for fruit and vegetable plants described above, specifically step four, is as follows: When watering with transplanting fertilizer after seedling transplanting, only the middle drip irrigation belt is opened, with a water volume of 10-20 cubic meters per acre and a fertilizer application rate of 2 kg per acre; 7-10 days after transplanting, when watering with seedling establishment fertilizer, the middle drip irrigation belt is closed, and the two adjacent drip irrigation belts are opened, with a water volume of 8-12 cubic meters per acre and a fertilizer application rate of 3-5 kg ​​per acre; 50 days after transplanting, when watering with fruit expansion fertilizer, until the end of the planting period, the three middle drip irrigation belts are closed, and the two outermost drip irrigation belts are opened, with a water volume of 8-12 cubic meters per acre each time and a fertilizer application rate of 5-15 kg per acre each time.

[0010] The root-oriented induction cultivation method for fruit and vegetable plants described above uses a fertilizer for planting, which is any one or a mixture of any two or more of the following in any proportion: water-soluble organic fertilizer, water-soluble inorganic fertilizer, water-soluble organic-inorganic compound fertilizer, and water-soluble biological agent.

[0011] In the above-described root-oriented induction cultivation method for fruit and vegetable plants, the soil temperature during the planting process in steps three and four is 15-28℃.

[0012] In the above-described root-oriented induction cultivation method for fruit and vegetable plants, the carbon dioxide concentration during the planting process in steps three and four is 0.08-0.1%.

[0013] In the above-described root-oriented cultivation method for fruit and vegetable plants, the daytime light intensity during the planting process in steps three and four is 40,000-60,000 lux.

[0014] The advantages of this invention are: it significantly increases the length and density of roots compared to traditional planting methods, expands the range of water and fertilizer absorption, reduces competition for surface nutrients, enhances the plant's disease resistance and stress resistance, and achieves the effect of increasing the yield and improving the quality of agricultural products.

[0028] Example Date: January 22, 2026; Location: Xuzhuang Township, Jizhou County, Hengshui City; Cultivation Variety: Tomato; Area: 30 mu (approximately 2 hectares). Land preparation began on January 23rd, with 2000 kg of organic fertilizer and 100 kg of compound mineral fertilizer applied per mu. After rotary tilling and mixing the soil twice, raised ridges were created, 30 cm high, 1.1 m wide, and 1.4 m apart. Five drip irrigation tapes were laid evenly on each ridge, spaced 18 cm apart. The entire ridge was covered with a 0.1 mm thick transparent plastic film. Transplanting took place on January 25th, with 2200 tomato plants planted per mu. A row of seedlings was planted on the side of each ridge closest to the central drip irrigation tape, with a seedling spacing of 17 cm. After transplanting the seedlings, apply fertilizer and water, opening only the middle drip irrigation tape at this time, using 15 cubic meters of water per acre, and applying 2 kg of seaweed fertilizer per acre with the water. On February 3rd, 8 days after transplanting, when applying fertilizer and water to help the seedlings establish, close the middle drip irrigation tape and open the two adjacent drip irrigation tapes, using 10 cubic meters of water per acre, and applying 5 kg of high-phosphorus fertilizer plus amino acid fertilizer per acre with the water. On March 17th, 50 days after transplanting, apply fertilizer and water to promote fruit expansion, closing the three middle drip irrigation tapes and opening the two outermost drip irrigation tapes, using 10 cubic meters of water per acre, and applying 5 kg of balanced NPK fertilizer and 5 kg of fish protein fertilizer per acre with the water. Afterwards, apply a large amount of fertilizer plus organic fertilizer or micronutrient fertilizer every 10-12 days, using only the outermost two drip irrigation tapes, until the planting is completed on June 20th (planting process as follows). Figures 1-8 As shown in the figure, during the planting process, the soil temperature is controlled at 15-28℃, the carbon dioxide concentration is controlled at 0.08-0.1%, and the daytime light intensity is 40,000-60,000 lux; the average yield of tomatoes is 10,000 kg per mu, and the proportion of first-grade fruits is 92%.

[0029] Comparative Example Date: January 22, 2026; Location: Xuzhuang Township, Jizhou County, Hengshui City; Cultivation Variety: Tomato; Area: 2 mu (approximately 0.13 acres). Land preparation began on January 23rd, with 2000 kg of organic fertilizer and 100 kg of compound mineral fertilizer applied per mu. After rotary tilling and mixing the soil twice, raised ridges were created, 30 cm high, 0.7 m wide, and 1 m apart. A drip irrigation tape was laid in the middle of each ridge. The entire ridge was covered with a 0.1 mm thick transparent plastic film. Transplanting took place on January 25th, with 2200 tomato plants planted per mu. A row of seedlings was planted near the center of each ridge, with a spacing of 30 cm between seedlings. After transplanting the seedlings, apply a transplanting fertilizer solution at a rate of 15 cubic meters per acre, along with 2 kg of seaweed fertilizer per acre. On February 3rd, 8 days after transplanting, apply a seedling establishment fertilizer solution at a rate of 10 cubic meters per acre, along with 5 kg of high-phosphorus fertilizer and amino acid fertilizer per acre. On March 17th, 50 days after transplanting, apply a fruit-expanding fertilizer solution at a rate of 10 cubic meters per acre, along with 5 kg of balanced NPK fertilizer and 5 kg of fish protein fertilizer per acre. Afterward, apply a large amount of macro-nutrient fertilizer plus organic fertilizer or micronutrient fertilizer every 10-12 days, at a rate of 10 kg per acre each time, until planting ends on June 20th. During the planting process, maintain soil temperature between 15-28℃, carbon dioxide concentration between 0.08-0.1%, and daytime light intensity of 40,000-60,000 lux. The average yield of tomatoes is 7,500 kg per acre, with 79% being first-grade fruit.

[0030] A comparison of the planting results obtained from the examples and the comparative examples revealed that, under the same management conditions, the plants in the examples exhibited more vigorous growth, with root systems covering the entire ridge, and both the taproot and lateral root lengths exceeding 35 cm (e.g., ...). Figure 9 As shown), the plants do not age prematurely, have strong disease and stress resistance, high fruit yield, and excellent quality, with over 90% being first-grade fruit. In contrast, the plants in the comparison group showed weaker growth, with both the main root and lateral root lengths not exceeding 30 cm (e.g., Figure 10 As shown in the example, the plants exhibited severe premature aging, poor disease resistance, and a 25% lower yield per acre compared to the previous example. The above comparison demonstrates that tomatoes grown using the root-oriented induction cultivation method for fruits and vegetables of this invention show significantly increased root length and density compared to traditional methods. This expands the water and fertilizer absorption range, reduces competition for surface nutrients, enhances plant disease resistance and stress tolerance, and ultimately increases both yield and quality of agricultural products. The method is characterized by its simple implementation, extremely low input costs, and significant effects.
