摘要	为了提高河套灌区盐碱地番茄移栽成活率,以番茄定植孔采用土封孔为对照,监测了沙封孔、不封孔株间和根际的土壤水分、土壤盐分、土壤温度及番茄幼苗的生长状况。结果表明,不同处理株间土壤水分、土壤盐分、土壤温度无显著差异。沙封孔、不封孔与土封孔相比,根际0～10cm土层土壤水分降低了11.73%和14.80%,≥10～20cm土层降低了9.60%和13.64%;根际5cm土层最高温度降低了1.2和3.6℃,日均温降低了1.6和2.2℃;根际0～10cm土层土壤盐分降低了19.11%和24.84%,≥10～20cm土层降低了11.48%和19.67%。沙封孔、不封孔番茄幼苗移栽成活率较土封孔提高了20.57%和19.40%。河套灌区盐碱地地膜覆盖栽培番茄,定植时采用沙封孔或不封孔,可降低根际土壤水分及土壤温度,阻碍盐分表聚于根际土壤,提高了番茄幼苗的移栽成活率,该研究为河套灌区盐碱地种植番茄提供指导。
其他摘要	In order to improving tomato transplanting survival rate in saline and alkaline land in Hetao irrigation area, Inner Mongolia, taking the planting hole sealed by soil as control, soil moisture, temperature, salinity between plants and rhizosphere, and the growth of tomato seedling that the planting hole sealed by sand and planting hole with no seal were monitored. The result showed that soil moisture, temperature and salinity between plants of different treatments had no significant difference. Compared with the control, soil moisture of planting hole sealed by sand and planting hole no seal decreased by 11.73% and 14.80% in 0-10 cm soil depth, and decreased by 9.60% and 13.64% respectively in ≥10-20 cm soil depth; soil maximum temperature decreased by 1.2 and 3.6℃at 5 cm soil depth, and average daily temperature decreased by 1.6 and 2.2℃ respectively; soil salinity decreased by 19.11% and24.84% in 0-10 cm soil depth, and decreased by 11.84% and 19.67% compared to planting hole sealed by soil in ≥10-20 cm soil depth respectively. Tomato transplanting survival rate of planting hole sealed by sand and planting hole with no sealed increased by 20.57% and 19.4% compared to planting hole sealed by soil respectively. It was indicated that treatments of the planting hole sealed by sand or the planting hole with no seal at planting time when cultivating tomato in saline and alkaline land with mulching in Hetao irrigation area, Inner Mongolia, soil moisture and temperature in soil decreased, soil salt accumulation in soil hindered, tomato transplanting survival rate increased. This study provides guidance for saline-alkali soil planting tomato in Hetao irrigation area.
