盐碱荒地的改良利用一般都是以绿肥和水稻作为先锋作物。由于土地平整投资大,前两年收益小,故影响了盐碱荒地的开发利用速度。为了做到当年投资当年得益,1980年我们在全县五个碱改水的试点田里栽种了23亩浅水藕,当年亩产都在3000斤以上,亩产值800多元。1984年全县种植浅水藕6806亩,平均亩产4000斤以上,最高亩产达8000多斤,亩产值达2000多元。
Salt and alkali waste land improvement and utilization are generally based on green manure and rice as a pioneer crop. Due to the large investment in land leveling and the small income in the previous two years, the development and utilization rate of saline-alkali wasteland is affected. In order to benefit from the investment of the year, in 1980 we planted 23 mu of shallow lotus root in the experimental field of five alkali-modified water in the county. In the same year, the mu yield was more than 3000 pounds and the mu output value was more than 800 yuan. In 1984, the county planted 6806 mu of shallow water lotus root, with an average mu yield of over 4,000 kilos. The highest mu yield reached 8,000 kilos and the mu output value reached 2,000 yuan.
