宁波市江北区乍浦乡双顶山村朱庆根农户承包的农田中,有一些田块由于地下水位高,经常受到洪涝灾害的威胁,田间积水时间长,种植水稻产量低,且极不稳定,经济效益差。为合理利用土地资源,1999年他在低湿田种植水芋艿1.53亩(1亩=667平方米,下同),亩产达1540千克,扣除种子及培育管理等成本费用,每亩纯收入达1300元,比种植早、晚稻的亩收入仅为650元的经济效益成倍增长。其主要栽培经验总结如下。
Among the farms contracted by peasants in Zhuqinggen, Shuangding Village, Zhapu Township, Zhapu District, Ningbo City, some fields are often threatened by floods and floods due to high groundwater levels, and have long periods of accumulated water in the fields, resulting in low and extremely unstable rice production and economic benefits difference. In order to make rational use of land resources, in 1999, he planted 1.53 mu of water taro in a low-humidity field (1 mu = 667 m2, the same below), with a per-mu yield of 1540 kg. After deducting the cost of seed and cultivation management, the net income per mu reached 1300 Yuan, than the planted early and late rice acres of income of only 650 yuan doubled the economic benefits. The main cultivation experience is summarized as follows.
