Abstract:
The experimental material is nutritional bowl seedlings which planted 55 days in the same year on the agricultural development area in Karamy. This experiment purpose lies in delaying afforesting time. Using nutrition tray, grown Ulmus pumila seedling to afforest in growing season at June, July and August. This study mensurated the physiological and biochemical characteristics of experimental seedlings. The result showed that: physiological and biochemical index reduced in one or two days after afforestation, which would go up in the second or third day, could recover in the third or fourth day, and the recovering stage of Ulmus pumila is about 4 days and the survive rate achieve 95%. Compared with traditional afforestation technology, this technology has shorter recovering stage and higer survival rate of forestation and can delay afforesting time about 90—120 days, so it would be realistically significant in cosmically afforestation.
