农业作物植物、蔬菜和花卉以及观赏植物具有集中在15-25 ℃内的最佳生长温度范围。季节性的气温变化对农产品的生长有很大的影响。土壤增温栽培是农作物冷季生长的有效促进措施之一。脊增温一般是由地下暖水循环完成的。此外，还有另一项研究观察了大葱的生长过程，使用电热丝进行土壤加热。这些研究表明，土壤变暖对农产品的生长有促进作用。但以往的研究都是以重油或电力为燃料进行土壤增温。前期研究的试验结果表明，低温季节利用地热进行土壤增温种植业的热量与其促生长效果之间存在着一定的关系。这种促进生长的效果已被以前在很小的热量土壤升温下进行的实验研究所认可。利用地下2- 4米的地热源，全年保持15-25 ℃的温度范围，用于土壤增温。研究表明，暖季土壤降温的热量与其促生长效果有一定的关系。通过在实际垄位上进行平地和高台两种方式的芥菜-菠菜栽培试验，证明了其促生效果。通过连续5年12次或10次的实际试验，评价了其对植物生长的促进作用，即对植物的增重、株高和叶片数的影响。本文叙述了用铜管或水循环调节土壤温度的促生效果与热量的关系。本研究提出的新型土壤降温系统能在小于25 MJ/m2的热量范围内对垄体进行降温，对栽培有13-22%的促生率。
Agricultural crop plants, vegetable and flower and ornamental plants, have an optimum growth temperature range that concentrates within 15-25 C. A seasonal temperature change has strong influence on growing of agricultural products. The soil warming for plant husbandry is one of the effective growth promotion methods for agricultural crop plant in cold season. Generally, the ridge warming is performed by warm water circulation of underground. Moreover, there is another research which observed the growth process of the Welsh onion using an electrically heated wire for soil warming. These studies showed that the soil warming brings growth promotion of agricultural products. But all passed studies are carried out by using the heavy oil or electric power for soil warming as fuel. The experimental result of previous study was shown that the relationship between heat amount of soil warming for plant husbandry by ground heat and the growth promoting effect in cold season. The growth promoting effect was recognized by the previous experimental study that had been carried out under the very small heat amount soil warming. The underground 2-4m ground heat source that keeps temperature range 15-25 C through a year was used for soil warming. This study shows the relationship between growth promoting effect and heat amount of soil cooling in warm season. The growth promoting effect is proved by the Japanese-mustard-spinach cultivation experiment by using both ground and high-bench at the actual ridges. The growth promoting effect, weight, height and number of leaves, is evaluated in 12 or 10 times actual experiment for five years. This paper describes the relationship between growth promoting effect and the heat amount of soil temperature regulation by using copper pipe or water circulation. The new soil cooling system that is suggested by this study is able to cool the ridge at the heat amount range of< 25 MJ/m 2, and it brings the growth-promoting rate of 13-22% on cultivation.
