摘要
研究了保护地渗灌管不同深度对土壤水盐动态、番茄生长发育及产量的影响。结果表明 ,渗灌管的埋深越浅 ,灌水周期越短 ,盐分积累越多 ;渗灌管埋深 3 0cm、管下铺设防渗槽时 ,有利于抑制盐分积累 ,番茄生长旺盛 ,株高、茎粗、果径等指标表现最佳 。
Influences of infiltration depth on the dynamic of so il water and salt, and the growth and yield of tomato were studied in protected f ield. The results showed that the shallower the porous pipe was buried, the shor ter the irrigation cycle and the more the salt accumulation. It was favorable to inhibit salt accumulation when the depth of porous tube was 30 cm and muck tren ch under it, in the meantime, the tomato grew well and the height of trunk, the thickness of stem and the diameter of fruits were the best, as well as the yield of tomato and utilization efficiency of water.
