Scope

Scope: This document specifies the principles, fertilization dosage, application period, and application methods for high-standard green kiwifruit cultivation in Pujiang County, Sichuan Province. This document is applicable to high-standard green kiwifruit cultivation in Pujiang County, Sichuan Province. Main technical content: 3.1 Water-fertilizer integration: By using a pressure system, water and fertilizer are integrated according to the soil nutrient content and the nutritional and water needs of citrus, and then applied evenly through irrigation and spray irrigation to improve fertilizer and water utilization rates and meet the needs of crop growth and agricultural production. 3.2 Multifunctional compound fertilizer: A multifunctional compound fertilizer designed to improve the utilization rate of nitrogen, phosphorus, and potassium, promote the formation of soil agglomerate structure, stimulate root growth, provide comprehensive nutrients, and have diverse application methods (can be applied as top dressing, irrigation, and drip irrigation), and be environmentally friendly. Technical indicators: Water-insoluble matter ≤ 0.2%, water-soluble organic matter ≥ 8%, N+P2O5+K2O ≥ 30%, average utilization rate of nitrogen, phosphorus, and potassium ≥ 40%, trace elements ≥ 0.2%, biostimulants ≥ 200 ppm, and soil agglomerate structure repair agents ≥ 750 ppm. 3.3 Acid-adjusting organic fertilizer: An acid-adjusting organic fertilizer designed to improve soil acidification, promote the formation of soil agglomerate structure, and stimulate root growth, and be environmentally friendly. Technical indicators: Acid soil conditioning agent ≥ 4%, N+P2O5+K2O ≥ 5%, organic matter ≥ 30%, and pH: 5.5–8.5. 3.4 Biostimulants: A new type of functional fertilizer derived from natural products and/or microorganisms that stimulate plant growth and development, such as improving the absorption and utilization efficiency of nutrients, enhancing tolerance to abiotic stress, and improving c
