农技“良方”巧应对 秋粮“战高温”稳向前

Core Viewpoint - The article emphasizes the impact of high temperatures on autumn crops, particularly rice, corn, and soybeans, and outlines strategies for farmers to mitigate heat damage through water management, fertilization, and pest control [1][2][4]. Group 1: Temperature Management - High temperatures have become a significant concern for rice, corn, and soybean crops, especially during critical growth stages [2][3]. - Continuous high temperatures above 35°C for three days or more can lead to heat damage, necessitating immediate action from farmers [2]. Group 2: Water Management Strategies - Farmers are advised to use deep water irrigation and maintain appropriate water levels in rice fields to reduce heat stress [3]. - In areas with limited water resources, coordination with water management departments is crucial to ensure adequate irrigation [3]. Group 3: Fertilization Techniques - To combat the adverse effects of high temperatures, farmers should supplement rice with potassium fertilizer and other nutrients during critical growth phases [4]. - For soybeans, the application of nutrient solutions like potassium dihydrogen phosphate is recommended to enhance heat resistance [4]. Group 4: Pest and Disease Control - Continuous monitoring for pests and diseases is essential during the critical growth period of autumn crops [5][6]. - Farmers are encouraged to use a combination of pesticides and growth regulators to effectively manage pest outbreaks and enhance crop resilience [6].
