Seedling Raising Technique for Pistacia vera

用地产成熟的'Kerman'品种的种子于0～5℃条件下层积60 d,再用300 mg/L赤霉素浸泡6～8 h后催芽,种子萌芽率达75%.3月底育苗,5月中旬移植,2年生苗平均高78 cm,地径1.5 cm.播种前切断种子胚根,可明显促进幼苗侧根和须根的生长.耐盐碱试验显示,苗期耐盐在0.55 g/ml以下.在壤土、沙壤土和粘土上培育苗,在苗的高和地径生长量方面,壤土和沙壤土无显著差异,而与粘土差异显著.在苗木木质化前用根腐灵稀释1000倍灌根和叶面喷洒能有效地防治根腐和根茎腐烂病.

Seed nuts of the local cultivar Kerman were stratified under 0-5 ℃ for 60 d, then they were soaked in GA （300mg/L） for 6-8 h for germination acceleration. The rate of germination reached 75 percent. Seeding started in late March and seedlings were transplanted in mid May. The two-year＇old seedlings are 78 cm in mean height and 1.5 cm in mean basal diameter, respectively. To cut off the radicles before sowing could remarkably promote the growth of lateral roots and fibrous roots. Result of saline and alkali-tolerance test showed that salt tolerance of seedlings was below 0. 55 g/ml. There was no marked difference between loam and sandy loam in the growth of height and basal diameter, but there existed noticeable difference between loam, sandy loam and clay. To irrigate the roots and spray the leaves could effectively prevent and cure the black rot disease and the root and stem rot disease by Fenaminosulf diluted 1 000 times, before seedlings got lignified.
