南疆各地进行塑料大棚蔬菜栽培,一般都先在加温温室内育苗,然后在大棚内定植栽培。加温温室加温时间多在40天左右,一个60平方米的育苗加温温室,一冬需烧柴6,000多公斤。我区煤炭、石油等资源虽较丰富,但目前产量有限,分布不均,加之交通不便,许多县和农场燃料相当缺乏,广大农村烧柴更为紧张,因而许多单位想利用塑料大棚进行冬季蔬菜生产都不能如愿。到目前为止,大棚蔬菜生产仅限于城镇郊区和少数有条件的单位,而且只能进行小面积栽培。
Plastic cultivation in southern parts of the greenhouse vegetable cultivation, generally first in the greenhouse warming nursery, and then planted in greenhouse cultivation. Warming Greenhouse heating time more than 40 days, a 60 square meters of nursery heating greenhouse, a winter need to firewood more than 6,000 kilograms. Although coal, petroleum and other resources are abundant in our area, the current production is limited and unevenly distributed. In addition, due to inconvenient transportation, many counties and farms have a shortage of fuel. The burning of firewood in the vast rural areas is even more tense. Many units therefore want to use plastic greenhouses for winter vegetables Production can not do so. So far, vegetable production in greenhouses has been limited to suburban areas and a handful of qualified units, and only small-area cultivation is possible.
