[0057] The present invention provides a method for efficiently planting golden locust in purple shale soil, and the specific steps are as follows:

[0058] S1. Soil analysis and improvement

[0059] Soil analysis: First, a detailed physical and chemical analysis of the purple shale soil was conducted, including pH value, organic matter content, nutrient status (nitrogen, phosphorus, potassium, etc.) and soil structure.

[0060] The method of physical and chemical analysis is: collect soil samples, air-dry, grind and sieve them, use chemical analysis methods to determine indicators such as pH value, organic matter content, nitrogen, phosphorus and potassium content, and use microscopic observation to analyze soil structure.

[0061] pH adjustment: Based on the analysis results, if the soil pH is below 6.5, apply quicklime powder, spread evenly and mix mechanically through deep tillage to increase the soil pH to 6.5-7.0.

[0062] If the pH is above 7.0, take measures to adjust the pH to 6.5-7.0, such as applying acidic fertilizers or soil washing.

[0063] Due to the characteristics of purple shale soil, its pH value usually does not exceed 7. However, if the soil pH value exceeds 7 and has an adverse effect on the growth of golden locust trees, such as reducing the effectiveness of certain nutrients or affecting the balance of soil microbial communities, corresponding adjustment measures need to be taken, such as applying acidic fertilizers or soil leaching.

[0064] Organic matter improvement: For soils with organic matter content below 2.5%, apply well-rotted farmyard manure and return straw to the fields to gradually increase the soil organic matter content to above 2.5%.

[0065] Nutrient supplementation: Formulate a fertilization plan based on the results of soil nutrient tests. Apply nitrogen, phosphorus and potassium compound fertilizers, divided into base fertilizer and topdressing, to ensure balanced nutrient supply.

[0066] If the soil nutrient test results show that the soil nitrogen content is lower than 1.0g / kg, the phosphorus content is lower than 0.5g / kg, and the potassium content is lower than 10g / kg, apply nitrogen-phosphorus-potassium compound fertilizer, which is divided into base fertilizer and topdressing. Each application should make the soil nitrogen content reach 1.0-1.5g / kg, the phosphorus content reach 0.5-1.0g / kg, and the potassium content reach 10-15g / kg.

[0067] Among them, basal fertilizer accounts for 60% of the total fertilizer application, and topdressing accounts for 40%. Base fertilizer is applied before planting, and topdressing is applied twice during the peak growth period.

[0068] The purpose of soil structure analysis is to understand the soil's porosity, aggregate stability and other properties, so as to evaluate the soil's aeration, water retention and fertility retention capabilities, and provide a more comprehensive and accurate basis for subsequent soil improvement and golden locust tree planting.

[0069] S2. Seedling Optimization

[0070] Seedling selection: Choose three-year-old healthy golden locust seedlings without diseases and insect pests, with seedling height ≥1.5 meters, ground diameter ≥2.5 centimeters, well-developed root system and no mechanical damage.

[0071] Seedling treatment: Prune the seedlings properly before transplanting, remove diseased and weak branches, reduce water evaporation, and improve the survival rate.

[0072] S3. Planting technology

[0073] Planting time: Planting should be done when the temperature is stable above 10℃ in spring. It is best to plant in mid-January to mid-February.

[0074] Planting layout: adopt wide and narrow row spacing layout, with wide row spacing of 2.2 to 3.5 meters, narrow row spacing of 2 to 3 meters, and plant spacing of 2 to 3 meters.

[0075] Planting operation: The planting depth is controlled so that the root neck is slightly higher than the ground, and the planting quantity is 1020 plants per hectare to ensure a reasonable group structure and good ventilation and light conditions.

[0076] S4. Moisture Management

[0077] Irrigation system construction: Establish a drip irrigation system and implement dynamic regulation based on the water demand characteristics of golden locust trees at different growth stages. Maintain soil moisture content at 60%-70% of field water holding capacity during the seedling stage, and increase to 70%-80% during the vigorous growth period.

[0078] Moisture monitoring: Use soil moisture sensors to monitor in real time, combined with local rainfall forecasts, to intelligently adjust irrigation frequency and duration to avoid excessive or insufficient water.

[0079] S5. Pest and disease control

[0080] Biological control: Use biological pesticides such as Bacillus thuringiensis preparations to prevent leaf-feeding pests such as Sophora japonica loopers. The dosage is 300 grams per hectare and spray with water.

[0081] Ecological control: For common root rot, control it by improving drainage conditions and applying Trichoderma, with 5 kg of Trichoderma applied per hectare.

[0082] S6. Pruning and shaping

[0083] Stem pruning: Stem pruning is performed during the young stage of golden locust trees, keeping the main trunk height at 1.4 to 1.6 meters to promote uniform distribution of side branches. It is best to perform stem pruning in the spring of the second year after planting.

[0084] Winter pruning: After entering the fruiting period, thinning and pruning are carried out during the winter dormancy period every year to remove dead branches and diseased and weak branches, maintain the openness of the crown, and improve light utilization.

[0085] When thinning branches, remove crossed branches, overlapping branches, inward branches and other branches that affect the ventilation and light transmission of the crown, and retain strong and reasonably distributed branches; when pruning, cut off 1 / 3-1 / 2 of the one-year-old branches to promote branch renewal and flower bud differentiation. At the same time, remove dead branches, diseased branches, maintain the openness of the crown, and improve light utilization.

[0086] S7. Harvesting and processing

[0087] Harvest time: The fruit of golden locust tree generally matures from mid-July to early October, when the fruit pods turn from green to yellow and the seeds become full.

[0088] Centralized harvesting: Use a combine harvester for centralized harvesting, followed by immediate threshing and drying to control the moisture content of the grains to below 12% for long-term storage.

[0089] Selection and grading: The golden sophora seeds are selected and graded, packaged and stored to ensure that the product quality meets market requirements.

[0090] The production processes, experimental methods or detection methods involved in the embodiments of the present invention, unless otherwise specified, are all conventional methods in the prior art, and their names and / or abbreviations are all conventional names in the field, and are very clear and unambiguous in the relevant application fields.
