宁海地处浙江中部沿海,一年四季分明,芋艿——晚稻种植模式在当地深受农民欢迎,常年种植达700公顷。由于芋艿前期生长缓慢,行间空隙大,植株开展度小,不能充分利用土地和光能。我县越溪乡东坑村农民自1995年以来采用草莓与芋艿套种,取得较好的经济收入。1997年该村种植芋艿/草莓——晚稻2.8公顷,草莓3月中旬开始采摘,5月初采收完毕;芋艿在7月中下旬收获;芋艿收后插种晚稻。与芋艿——晚稻模式比较,不仅未降低芋艿和晚稻的产量,而且每公顷多收了7500千克草莓,增加经济效益近75000元。现将主要技术措施介绍如下。
Ninghai is located in the central coast of Zhejiang Province, all year round distinct, taro - late rice planting patterns in the local farmers by far, up to 700 hectares of perennial planted. Due to the slow growth of early taro, interstitial space between the large, small degree of plant development, can not make full use of land and light energy. Farmers in Dongkeng Village, Yuexi Township, I County, have used strawberry and taro intercropping since 1995 and have achieved good economic income. In 1997 the village planted taro / strawberry - 2.8 hectares of late rice, strawberry picking began in mid-March, early harvesting in early May; taro harvest in late July; taro harvest after planting late rice. Compared with the taro-late rice model, the yield of taro and late rice was not reduced. Moreover, 7500 kg of strawberries were collected per hectare, increasing the economic profit by nearly 75,000 yuan. Now the main technical measures are described below.
