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.

Key Technical Points for Light Regulation in Greenhouse Grape Cultivation
In greenhouse grape cultivation, because the light intensity inside the shed is often less than 70% of that outdoors, it has a significant adverse effect on grape growth and fruiting, often causing serious flower and fruit drop, poor fruit coloration, low sugar content, poor flower bud differentiation and other phenomena, greatly reducing grape yield and quality. Therefore, enhancing...
