| 摘 要： | 在干旱的条件下,蒸腾作用会引起植物大量丢失水分,常常会引起水分亏缺和脱水的伤害.我国黄土半干旱地区是退耕还林、林业生态工程建设的重点地区.由于当地降水相对不足但潜在蒸散力大的特殊气候条件,使人工造林遇到了极大的困难,此时叶面喷施抗蒸腾叶面肥不仅能提供植物生长所需养分,而且还能抑制植物蒸腾作用,提高植物水势,减少植物水分的蒸发量,一定程度上提高植物生存能力.以黄土高原干旱半干旱地区造林主要树种刺槐、白榆、火炬树为主要研究对象,以自制的2种抗蒸腾叶面肥及市场上已推广施用的叶面肥肥效为主要依据,探讨自制肥料在降低植物蒸腾作用方面的效果.并最终得出自制A或自制B、白榆、稀释300～1200倍、土壤绝对含水量为10%～25%时对降低植物蒸腾速率效果最明显.

| Abstract: | Under the arid conditions,transpiration of plants can cause substantial loss of water.Semi-arid loess areas are the key areas for the returning farmland to forest and eco-forestry projects.In these areas,however,potential evapotranspiration is stronger and precipitation is less than other areas.Artificial afforestation is confronted with great difficulties.Spraying the new anti-transpiration foliar fertilizer may provide the necessary nutrients,inhibit transpiration,improve plant water potential,and to some... |
