项目摘要

An investigation was done on the growing condition of vegetable cultivated in culture ground by passing ground water of Dam developed at 23ﾟC through VP pipes below the culture ground on the supposition that the ground water help maintains the culture ground media cool or hot. Culture media was prepared by putting soil in wooden box (180x40x40cm). Cool or culture ground was maintained by passing 23ﾟC ground water of Dan through VP pipes (5cm diameter) installed below 5cm from the soil surface. Three kinds of culture ground were prepared viz. no pipe (control), one pipe and two pipes culture ground. Lettuce (Sarada na) and Chisya were grown in summer and winter seasons of 1995-96, respectively. In 1997, Spinach was grown to investigate the cool orhot effect of culture ground. Results of the experiments :1995-96 crop season :The highest yield of Lettuce (Sarada na) cultivated summer season was obtained from the culturemedia lined with two VP pipes followed by the one VP pipe. On the cont … More rary, no pipe culture media (control) gave the lowest yield. In comparison to no pipe culture media (control), the harvested yield of one pipe and two pipes culture media were 1.8 and 2.2 times higher, respectivery. Thus from the result it is seen that ground water of Dan showed cool effect on the crop growth. While in winter season, the first crop of Chisya showed the result that one pipe and two pipes culture media gave 13.0 and 16.0 times higher yield than that of no pipe culture media (control). And the second crop of Chisya showed that one pipe and two pipes culture media produced 3.6 and 4.3 times higher yield than of no pipe culture media (control). It was obvious from the above result that the ground water from the Dam passed through VP pipes below the culture ground showed hot effect on the growth of Chisya.1997 crop season :Spinach seeds were sown in May (spring), July (summer), September (Autumn) and November (Winter) of 1997 and the experiments were conducted accordingly. The May crop was failed due to flowering early growth stage in all VP pipes culture media. The July crop was also badly affected dueto high temperature effect and consequently the growth was stopped by the early flowering. Depending on the above results, it is clearly seen that spring and summer seasons spinach cultivation are difficult. Autumn and winter seasons spinach cultivation were favorably affected by all kinds of culture media. Above 50-70% higher spinach yield was obtained from the culture media lined with VP pipe compared with that of the no VP pipe culture media (control). Less

在假定地下水有助于维持栽培基质的冷或热的前提下，通过将23 ℃的大坝地下水通过栽培基质下方的VP管，对栽培基质中蔬菜的生长状况进行了调查。通过将土壤放入木箱（180 X 40 X 40 cm）中来制备培养基。通过将23 ℃的Dan地下水通过安装在离土壤表面5cm以下的VP管（直径5cm）来保持凉爽或培养地面。设置了无管、单管和双管三种培养场地。1995- 1996年夏季和冬季分别种植Lettera（Sarada na）和Chisya。1997年以菠菜为试材，研究了栽培地的冷热效应。试验结果：1995 ~ 1996年夏季栽培时，以2根VP管后1根VP管的栽培方式产量最高。关于我们 ...更多信息很少，没有管培养基（对照）得到最低的产量。与无管培养基（对照）相比，单管和双管培养基的收获产量分别高1.8和2.2倍。由此可见，丹地地下水对作物生长具有降温作用。冬季第一茬赤霞珠结果表明，1管和2管栽培比对照增产13.0和16.0倍。第二茬的奇西雅表现为一管和双管栽培比无管栽培增产3.6倍和4.3倍。从上述结果可以明显看出，从大坝通过VP管下面的培养地面的地下水表现出对Chisya的生长热效应。1997年作物季节：菠菜种子播种在1997年5月（春季），7月（夏季），9月（秋季）和11月（冬季），并进行相应的实验。5月茬在所有VP管培养基中均因开花早而失败。7月的作物也受到严重影响，由于高温的影响，因此生长被提前开花所停止。根据上述结果，可以清楚地看到，春季和夏季菠菜种植是困难的。不同基质对秋冬茬菠菜栽培均有较好的影响。与不衬VP管的培养基（对照）相比，衬VP管的培养基获得了50-70%以上的菠菜产量。少
