Core Viewpoint - The winter strawberry harvest in Chengdu, Sichuan, has begun, featuring various types including red, white, and pink strawberries, with a total planting area exceeding 40,000 acres and an annual yield of over 70,000 tons [1][11]. Group 1: Strawberry Cultivation Techniques - Chengdu's Tianfu New Area is a key zone for winter strawberry cultivation, with over 2,000 acres dedicated to smart greenhouse farming since 2011 [3]. - The use of vertical farming techniques and smart greenhouses enhances strawberry growth conditions, utilizing a mix of materials like coconut husk and nutrient soil to create a disease-free environment [5]. - Pollination is managed through the introduction of beehives to ensure even distribution of pollen, which helps reduce deformed fruits and improves both taste and appearance [7]. Group 2: Strawberry Varieties and Characteristics - Currently available winter strawberry varieties include "Hongyan" (red), "Fenyue" (pink), "Jiande Bailu" (white), and "Heizhenzhu" (dark red), each with distinct flavors and appearances [9]. - The "Jiande Bailu" variety is noted for its high sweetness and rich aroma, making it the most popular choice among consumers [11]. - Over the past decade, approximately 200 strawberry varieties have been developed in Sichuan, with color and taste differences attributed to genetic factors and anthocyanin accumulation [12][14]. Group 3: Innovative Farming Practices - The "smart strawberry factory" in Chengdu's Wenjiang district allows for year-round strawberry harvesting, producing 30 to 40 times the yield of traditional farming methods [21]. - This facility employs vertical farming design, with over 13,000 strawberry plants cultivated in a 200-square-meter area, equivalent to 3 acres of traditional land [23][25]. - Advanced technology, including automated irrigation systems and real-time monitoring of environmental parameters, supports optimal growth conditions, enabling a stable annual yield of 73 tons [27].
