近日来,我们对华家乡某农民塑料大棚种植葡萄情况做了调查,情况如下: 这位农民在0.6亩塑料大棚里共种植了400株巨丰葡萄,现在是第三年,1987年平均株产5公斤,总产2000余公斤,毛收入5000余元.塑料大棚葡萄的特点是:结果分为三个高峰期,并且上市早,收获结束晚。第一期葡萄在8月上旬上市,比一般葡萄提前上市15天,最后一期葡萄可陆续采摘到寒冷的12月末结束。而一般葡萄到10月上旬就基本收获完,塑料大棚葡萄比一般葡萄延长成熟
In recent days, we have investigated the condition of cultivating grapes in a peasant plastic greenhouse in a rural area of China. The situation is as follows: The farmer planted a total of 400 Jufeng grapes in a 0.6-mu plastic greenhouse. It is now the third year and the average yield in 1987. 5 kg, a total output of more than 2,000 kg, gross income of more than 5,000 yuan. Plastic greenhouses are characterized by: The results are divided into three peak periods, and the market is early, the harvest is over. The first phase of the grape is listed in early August and is 15 days ahead of the average grape. The last phase of the grape can be harvested until the cold end of December. In general, the grapes are basically harvested by the beginning of October, and plastic sheds are riper than normal grapes.
