Breeding vegetable seedlings by electric heating wires in the plastic vegetable greenhouse is a kind of new vegetable seedling breebing pat- terns being extended in Shaanxi Province.The experiments have dem- onstrated:(1) when the electric heating wires are used to breed vegetable seedlings in the plastic greenhouse in Xian areas,there must be a small arched cover tent inside of the greenhouse.Thus,both geothermal and atmospheric temperatures nedded for vegetable seedlings of different species can be effectively ensured.As to heat-shielded performaees of the small arched tent,the night temperature can be raised to 3.7℃ and the geothermal temperature raised to 11℃ in com- parsion of agricultural used adhesive-bonded cloth with plastic films for the cover.(2)In seedling breeding by electric heating wires in the plastic greenhouse,power consumption is different because of various vegetable species.Power consumption for tomatoes is the least with 7 Kw-hrs/m~2 in total;that for cucumber is the next with 14 Kw-hrs/m~2 in total;that for egg plant and pepper are the most with 27Kw-hrs/m~2 in total.(3)comparsion was made among seedling breeding by electric heating wires in the plastic greenhouse,that by kitchen range heating, that in the sun-facing furrows by electric heating wires in the usual greenhouse and that by shelf patterns in the glasshouse.As a result,though defferenees among seedlings are not very significant, inputs and economical returns of the former are much more superior to the other three patterns of the latter.

蔬菜塑料温室电加温线育苗,是陕西地区正在推广的一种蔬菜育苗新形式。通过试验表明:①在西安地区采用塑料温室电加温线育苗,室内必须有小拱棚覆盖,才能有效地保证各种菜苗所需的地温和气温。小拱棚的保温性能:农用无纺布与塑料薄膜比较,夜温可提高3.7℃,地温可提高11℃。②在塑料温室电加温育苗中,由于蔬菜种类不同,耗电量也不同:番茄耗电量最少,每平方米总耗电量为7度;黄瓜次之,每平方米总耗电量为14度;茄子、辣椒最多,每平方米总耗电量为27度。③塑料温室电加温线育苗,与常用的温室炉灶加温育苗、阳畦电加温线苗以及玻璃温室架式育苗相比,其苗子质量虽然差异不显著,而它的投资和经济效益却优于这三种形势。

A total of 18 measuring temperature points was set inside and outside the greenhouse, at the air,the surface of the ground,and 5,10,15,20,40,60,80 cm deep under the ground respectively. The temperature at each point was measured every day for a whole year. Correlation coefficients, regression equations...

Measurement, analysis and study were conducted on the efficiency of the system of storing the solar heat energy under the ground of a vegetable greenhouse, located in Xining in the QinghaiTibetan Plateau. A total of 18 measuring temperature points was set inside and outside the greenhouse, at the air,the surface of the ground,and 5,10,15,20,40,60,80 cm deep under the ground respectively. The temperature at each point was measured every day for a whole year. Correlation coefficients, regression equations and other parameters were calculated, with results indicating (in the order of points mentioned above) that: 1. the indoor annual average temperatures rose to 17.9,20.2,19.1,18.7,18.5,18.7,18.7,18.9,18.3 ℃ respectively, 2. the indoor temperature increments were 12.2, 9.2, 10.8, 10.7, 10.7. 11.1, 11.0, 11.2, 10.3 ℃,compared with the outdoor annual average temperatures, 3. the dynamic equilibrium of the heat stored under the ground by the system reached to 5.68 GJ. After both the earth and the air temperatures inside the greenhouse rose, many kinds of vegetables grew in and kept it green all the year, and therefore, definits economic benefits were produced.
