This invention discloses a method for regulating early maturity of citrus fruits based on environmental data processing under plastic film mulching, specifically relating to the fields of agricultural data processing and technology extension services. It addresses the problem that existing early maturity regulation models, due to their singular optimization objective, neglect the microecological changes caused by plastic film mulching, leading to increased pest and disease risks. By acquiring soil temperature and humidity data after plastic film mulching, and based on a pre-established correlation model, the method determines the pathogen inhibition function imbalance index and carbon and nitrogen cycle disturbance intensity, characterizing soil microecological health, and assesses the risk level of pest and disease occurrence. Combined with sensitivity analysis results of the original agricultural operation plan, key agricultural operation parameters are adjusted in a targeted manner. The generated comprehensive regulation plan is serialized into a distributable and executable agricultural technology extension service package and promoted for implementation. This achieves end-to-end data processing from environmental data to microecological risk assessment to customized agronomic plan generation and services, improving the accuracy of agricultural technology extension.

This invention discloses a green and ecological planting method for daylilies, belonging to the field of agricultural planting technology. It addresses the technical problems of excessive reliance on chemical fertilizers and traditional mulching in current daylily cultivation, leading to soil ecological imbalance and low fertilizer utilization. The method includes: applying organic fertilizer made from cow and sheep manure and Asteraceae plant residues through aerobic composting, using a layered strip application method. First, fully decomposed organic fertilizer is applied as a base fertilizer layer in the planting furrow, followed by semi-decomposed organic fertilizer that has completed the main fermentation stage but not the later aging stage as a middle layer fertilizer; after land preparation and ridging, wood ash is spread on the ridge surface, followed by the laying of black fully biodegradable mulch film; finally, holes are made in the mulch film for daylily seedling planting. This method is mainly used for sustainable ecological planting of daylilies, improving soil fertility and structure, regulating soil pH and providing potassium, conserving moisture and suppressing weeds while avoiding residual pollution, thereby increasing daylily yield and quality while reducing environmental impact.
