Detailed Explanation of Pollution-Free Cultivation Techniques for Strawberries in Plastic Greenhouses
(1) Variety selection: Choose varieties with early flower bud differentiation, shallow dormancy, and good cold resistance in low-temperature seasons, such as Chunxiang, Fengxiang, Lihong, Mingbao, Jingbao, Nyoho, and Hokowase. (2) Cultivating strong seedlings: 1. Carefully select mother plants. In March-April of the current year, select plants from the strawberry production greenhouse with vigorous growth, good inflorescence fruiting, few deformed fruits, well-developed root systems, and no pests or diseases as mother plants. Plant them in a dedicated seedling nursery to cultivate and propagate runner seedlings. Apply 2000-3000 kg of organic fertilizer and 10 kg of compound fertilizer per mu in the nursery. Make beds 2 m wide, with a planting row spacing of 1 m and a plant spacing of 0.3-0.4 m. After they establish, apply nitrogen fertilizer as early as possible, keep the soil moist, and remove all inflorescences that appear to promote runner growth.
