摘要：为了解决草莓冬季生产灌溉水温偏低而影响草莓生长、产量和品质的难题，以“圣诞红”草莓为试材，采用简单经济的方法，即在灌溉系统首部安装蓄水桶，利用太阳光照对灌溉水进行加温。结果表明：加温灌溉系统可以将灌溉水温提高1～2 ℃，灌溉土壤温度比未加温灌溉平均提高了1.2 ℃，有效促进了草莓生长。相比未加温灌溉，加温灌溉的草莓单果质量显著提高了11.12%（12月），果实糖度显著提高了1.24%（1月），总酸度显著降低了44.19%（2月），糖酸比显著提高了59.74%（2月），产量提高了14.17%，水分生产效率提高了13.89%，667 m2产值增加了6 240元。综合来看，加温灌溉系统具有一定的推广应用价值。

Abstract: In order to solve the problem of low temperature irrigation water of strawberry production in winter, which affected the growth, yield and quality of strawberry, strawberry cultivar 'Shengdanhong' was used as experimental materials and a simple and economical method was adopted, which was to install a water storage bucket at the head of irrigation system and used sunlight to heat the irrigation water. The results showed that the heated irrigation system could increase the irrigation water temperature by 1-2 ℃ and the irrigation soil temperature increased by 1.2 ℃ compared with non heated irrigation, effectively promoting the growth of strawberry. Compared with non heated irrigation, the quality of strawberry single fruit under heated irrigation significantly increased by 11.12% (December), fruit sugar content significantly increased by 1.24% (January),total acid content significantly decreased by 44.19% (February), sugar acid ratio significantly increased by 59.74% (February), yield increased by 14.17%, water production efficiency increased by 13.89%, and output value increased 6 240 Yuan per 667 m2. Overall, the heated irrigation system had certain promotion and application value.
