我省实施南繁基地土壤地力提升行动

Core Viewpoint - The implementation of the soil fertility enhancement action at the South Breeding Base aims to improve soil quality and sustainability for agricultural practices in Hainan, particularly during the off-season for breeding activities [3][4]. Group 1: Soil Fertility Enhancement Action - The South Breeding Management Bureau has initiated a project involving the planting of 10,000 acres of the legume crop, Tianjing, to improve soil health during the off-season [3]. - The project has already covered approximately 40 fixed breeding bases and around 260 breeding units, demonstrating a commitment to sustainable land use [3]. - The investment of over 4 million yuan in this initiative reflects the importance of balancing land use and soil health [3]. Group 2: Benefits of Tianjing - Tianjing is chosen for its heat tolerance, flood resistance, salt tolerance, and disease resistance, growing up to 2.5 meters in just two months [4]. - The crop's effectiveness surpasses that of equivalent weight pig manure, significantly enhancing soil organic matter and nutrient content while reducing soil acidity [4]. - By occupying space that would otherwise be taken by weeds, Tianjing helps to disrupt pest and disease cycles, thereby reducing risks for subsequent breeding activities [4]. Group 3: Implementation and Management - The project employs a "full-process scientific management" approach, including land clearing, uniform seed sowing via drones, and soil amendment with lime to adjust pH levels [4]. - Regular guidance and supervision from technical personnel ensure the effective execution of the project [4]. - The improved soil structure has led to reduced costs for fertilizers and tillage in subsequent planting seasons, demonstrating tangible benefits from the soil enhancement efforts [5].
