哈密垦区葡萄裂果病预防及药剂选用综合措施的研究

Study on Prevention and Medicament Selection of Cracked Fruit Disease of Grape in Hami Land Reclamation Area

葡萄裂果病的发生是影响哈密垦区葡萄主栽品种无核白葡萄产量、品质的直接因素,为综合防治葡萄裂果病造成的危害,研究了无核白葡萄栽培中灌水量与生长调节剂的调控、搭建避雨棚、喷稀土处理以及化学药剂的综合预防措施效果。结果表明:稀土处理、搭建避雨棚和覆地膜处理的葡萄生长状况较好、裂果病发生较轻;灌水量与生长调节剂对葡萄裂果都具有很大的影响,并且全年灌水量为12 000m3.hm-2左右,生长调节剂260mg.kg-1(拉穗80mg.kg-1、膨大期180mg.kg-1)为宜;43%好力克和72.2%普力克水剂防治效果较好,分别达75.3%和67.03%。

The occurrence of grape cracked fruit disease is direct factor that affecting yield and quality of thompsons seedless,in order to control the harmfulness because of the disease,the effect of irrigation,growth regulator, lew, rear earth and medicament was studied. The results showed that the treatments of applying rear earth, setting up lew and covering film were better to the growth of grape, the disease occurrence was light. The effects of irrigation and growth regulator were significant on grape cracked fruit, the suitable amount of irrigation was 12 000 m3 · hm^-2 ,growth regulator was 260 mg· kg^-1. The medicament selection results showed that the control effect of 43% Haolike and 72.2% Pulike were better,about 75.3% and 67.03% ,respectively.
