精准施策促花忙！农业科技特派员深入从化区荔枝产区指导控梢促花工作

Core Viewpoint - The article discusses the importance of timely agricultural interventions in the lychee production area of Conghua District, Guangzhou, to ensure a successful flowering and fruiting season for the lychee industry, which is crucial for stable production and income growth for farmers [3][4]. Group 1: Lychee Industry Overview - Lychee is a key fruit in Conghua District, with a planting area of nearly 300,000 acres, featuring popular varieties such as Guiwei, Nuomizhi, Huaizhi, and Lingfengnuo, which are well-received in the market [2]. - The current period is critical for the differentiation of flower buds, and successful control of shoot growth is directly related to the yield of this year's lychee crop [3][4]. Group 2: Agricultural Interventions - To address production challenges faced by farmers, the Conghua District Agricultural Technology Promotion Center has collaborated with South China Agricultural University and local lychee industry associations to form a team of agricultural technology specialists [5][6]. - The team has conducted on-site investigations in major lychee production areas to assess flowering conditions and provide tailored guidance to farmers [7][8]. Group 3: Current Conditions and Recommendations - Observations indicate that some varieties, such as Jinggang Hongnuo, have shown initial bud growth, while others like Guiwei and Nuomizhi have not yet exhibited signs of budding [11][14]. - The lack of sufficient cold weather in late 2022 and early 2023 has negatively impacted the shoot control and flowering process, compounded by nutrient depletion from last year's abundant harvest [15][16]. - Recommendations for farmers include pruning weak branches, applying specific fertilizers, and managing irrigation to promote healthy bud development [19][20][21][31][32]. Group 4: Specific Management Measures - For trees that have not yet budded, it is advised to apply growth regulators and ensure adequate watering to stimulate bud growth [20][21]. - In cases of frost damage, measures such as covering trees with protective materials and timely irrigation are recommended to mitigate frost effects [42][43][44][46].
