天津地区种植草莓,安全越冬需要人工覆盖防寒。生产上常用的覆盖材料有马粪,藁秆、稻草、麦秸等。材料用量大,用工多、翌年覆盖物清除不净,地面杂乱影响田间作业,有些地方材料来源也较困难,限制了草莓发展。塑料地膜覆益栽培已成为农业上普及应用的增产措施,草莓栽培上也开始应用。我们于1985至1986年连续两年做了地膜覆盖草莓越冬防寒试验。结果表明,地膜覆盖对提高地温、保持土壤水分、保护苗株安全越 Strawberries planted in Tianjin, the need for artificial coverage of winter cold. Cover materials commonly used in production are horse manure, stalks, straw, straw and so on. Large amount of materials, labor and more cover the next year to clear the net, messy ground affect the field operations, some local sources of material is also more difficult to limit the development of strawberries. Plastic film mulching cultivation has become the popularization and application of agricultural production measures, strawberry cultivation also began to apply. We made the straw-mulching winter cold-proof test for two consecutive years from 1985 to 1986. The results showed that mulching could improve soil temperature, maintain soil moisture and protect seedlings more safely
