Besides,it analyzed the requirements for environmental factors in different growth stages of watermelons. The experiment obtained the following results.( i) Under the condition of high-density planting of small watermelons,the average air temperature range was 17. 48-21. 16℃ at the seedling hardening stage,the average air temperature range was 16. 68-25. 53℃ at the tendril elongation stage,and the average air temperature range was 15. 98-32. 06℃ at the fruiting stage. The average soil temperature range was 20. 56-23. 03℃ at the seedling hardening stage,the average soil temperature range was 20. 44-25. 51℃ at the tendril elongation stage,and the average soil temperature range was 18. 72-28. 84℃ at the fruiting stage. The average light intensity range was 2 359. 15-8 207. 44 Lux at the seedling hardening stage,the average light intensity range was 551. 98-9 170. 77 Lux at the tendril elongation stage,and the average light intensity range was 1 253. 59-9 644. 01 Lux at the fruiting stage. The average relative humidity range was 60. 69%-76. 40% at the seedling hardening stage,the average relative humidity range was 60. 85%-89. 89% at the tendril elongation stage,and the average relative humidity range was 42. 14%-93. 00% at the fruiting stage. The CO2 concentration range was 455-631 m L/m3 at the growth stage. 关 键 词：环境传感器 西瓜 种植技术 发展现状
