新型复垦基质适种作物初选

Preliminary Selection of Suitable Crops for New Reclaimed Medium

研究了新型复垦基质对作物出苗的影响,分析了各作物出苗率及苗期生长状况,探讨了不同作物对基质的适应性,初步确定了适宜的先锋作物。结果表明:粉煤灰与糠醛渣混合是能够满足作物生长的沉陷地复垦基质,使各作物的出苗率普遍提高,但基质对绿豆的苗期生长具有明显的抑制作用,在4种供试作物中,菠菜是最适合在基质中种植的作物,其次是谷子和棉花。

In this article, the effects of the new reclaimed medium on the emergence of crops were studied, the emergence rate (ER) and growth conditions during seedling stage were analyzed, the suitability of each crop to furfural residue was probed into. On this basis, proper pioneer crops were tentatively determined . The results indicated that the mixed medium of fine coal ash and furfural residue was suitable to cultivate crops, and the ER of each crop was increased. However, this medium resists mung bean to grow. The most suitable crop is spinach, and the next two are cotton and millet.
