| 摘 要： | 本文以四川汉源县核桃为对象,开展核桃病虫害调查,获得以下主要结果:汉源县核桃有害生物共计30种,其中危害较为严重的虫害为云斑天牛、木橑尺蠖、黄刺蛾、桃蛀螟、核桃举肢蛾等,病害普遍发生的是核桃炭疽病、核桃黑斑病、核桃缩叶病,具有潜在危害性的较大的是核桃木腐病、核桃枝枯病、核桃溃疡病和星天牛、茶丽天牛等对核桃枝干危害的有害生物。调查发现核桃有害生物种类随着温度的变化呈现周期性变化。汉源县4月气温10~30°C时虫害开始危害植株,病害也开始侵染植株,并随温度升高,种类增多,危害加重。11月气温10~20°C时有害生物危害降低,开始越冬。核桃有害生物种类以及危害程度与其种植环境有关。四旁树核桃、核桃和玉米混合种植有害生物危害较核桃纯林严重,核桃柑橘混合种植时有害生物种类较核桃纯林种类多,这可能与混栽植物间有共同有害生物有关,有关机理将进一步研究。

| Abstract: | In order to investigate the walnut diseases and insect pests,a field investigation was carried out in the artificial walnut plantation in Hanyuan county of Sichuan province.The main results were as follows:1)There were 30 kinds of walnut insect pests in Hanyuan County,among which the more serious pests were Batocera horsfieldi,Culcula panterinaria,Cnidocampa flavescens,Dichocrocis punctiferalis,Atrijuglans hetaohei,and so on.The common diseases were walnut anthracnosc,walnut black spot,walnut leaf defect.The more potentially harmful pests were walnut wood rot,walnut branch blight,walnut canker,Anoplophora chinensis and Rosalia lameerei,which were harmful to walnut branches.2)Harmful species of walnut insect pests changed periodically with the change of temperature.When the temperature was 10~30℃in April,the insect pests began to harm the plant,and the disease also began to infect plants.With the increase of temperature,the pests species increased and the harm became more serious.When the temperature was 10~20℃in November,the harmful degree of insect pests decreased and pests began to overwinter.3)The harmful species and harmful degree of walnut insect pests were related to the planting environmental factors.The harmful degree of pests in mixed plantation of walnuts and four-side trees and walnuts and corn was more serious than that of pure walnut plantation.There were more kinds of harmful organisms in mixed cultivation of walnuts and citrus trees than in pure walnut plantation.This phenomenon might be related to the common harmful pests among mixed plants,and the relevant mechanisms should be further studied. |
