盐碱地种植铁扫帚,对于增加大地植被,改善生态环境和提高经济效益具有十分重要的意义。 1 提高利用土地的经济效益 盐碱地种植铁扫帚比种高粱、向日葵经济效益高。据调查,种667m~2铁扫帚,收干苗子436kg,(三年平均产量),扎条帚872把,收入500～1400元,(价格受市场影响较大),而种高粱收50kg左右,连秫秸卖掉,只能收百元左右。 2 降低了土壤含盐量 The cultivation of iron brooms on saline-alkali soil is of great significance for increasing the vegetation on the earth, improving the ecological environment and increasing the economic benefits. 1 to improve the economic benefits of land use Saline cultivation of iron broom than sorghum, sunflower high economic efficiency. According to the survey, 667m ~ 2 iron brooms were harvested, 436kg were harvested and dried (with an average yield of three years), 872 barbs and bales of 500 to 1,400 yuan (the price was greatly affected by the market) Even straw sold, can only receive hundred or so. 2 reduces soil salinity
