| 摘 要： | 利用纳米材料处理水浇灌玉米(Zeamays),探讨了纳米材料对玉米磷营养的影响;用纳米材料处理水浸提磷矿粉,验证了纳米材料处理水对磷矿粉溶解性的促进作用。用纳米材料处理水浇灌玉米植株,可提高玉米的株高、茎粗以及生物量,使玉米植株地上部的氮磷钾的总量提高,同时可以提高植株中磷的含量7%~10%。取磷矿粉放于纳米材料处理水中,振荡、过滤,测定过滤液中的水溶性磷的含量,纳米材料可使磷矿粉浸提液中水溶性磷的含量较对照高20%~70%。利用纳米材料处理水提高磷矿的有效性,为提高磷的有效性、充分利用低品位磷矿提供了一条新的途径。

| Abstract: | This paper confirmed that nano-materials can increase the solubility of phosphorus powder and improve the phosphor nutrition of maize. Soaked maize using the water treated with nano-materials, can increase the plant height, stem diameter, biomass and the uptakes of NPK, as well as increase the contents of P in the maize aerial part from 7% to 10%. Having put phosphorus pow- der into water, librated and filtrated it, and analyzed the contents of water-soluble phosphor, the authors found that nano-materials can increase the contents of water-soluble phosphor in the leaching water from 20% to 70%. It provided a new way to improve the use of phosphorus. |
