吳茱萸价值較高.栽培亦易,管理粗放,成本低,农民甚感兴趣,把它作为重要副業之一。茲就作者在浙江調查結果对于生产上存在的問題作几点建议如下: 1.天牛的为害,严重的影响植株的生長年限及产量。当地农民把吳茱萸作为附帶的副業收入,故对防治不重视。首先,应了解天牛在当地气候环境下的生活習性,然后制訂出防治方法。現將一般的防治方法簡略地介紹如下: (1)捕杀幼虫在幼虫生活时期內,若發現树干下部有虫粪及木屑,可用细軟的銅絲,頂都作鈎,鑽入洞內,把幼虫拉出。工作时要細心与耐心,但不論年老年少的人均可操作,可充分利用劳动力。其次,用棉花粘上666粉剂,塞住洞口,由于666粉有接触、胃毒、薰蒸三种作用,当幼虫出洞拉粪粘上666粉时即可触杀致死或薰蒸致死。另外还可利用二硫化碳及DDT等化学药物防治。(2)成虫产卵前,用石灰水塗白树干基部。其配制量为生石灰10份,硫黄1份,清水40份。可防治成虫产卵。
Evodia higher value.Is also easy to cultivate, extensive management, low cost, farmers are very interested in it as one of the important sideline. Here are some suggestions on the problems existing in the survey results of Zhejiang Province as follows: 1. The damage caused by Celastrus angustifolia seriously affects the growth period and yield of the plants. Evodia local farmers as incidental sideline income, so do not pay attention to prevention and treatment. First of all, we should understand the nature of the weather in the local habitat, and then develop a prevention and treatment methods. Now general control methods are briefly described as follows: (1) killing larvae Larvae life period, if found in the lower part of the trunk of insect feces and sawdust, can be soft copper wire, the top are hooks, drill into the hole, the Larvae pull out. Work attentively and patiently, but work well with young people regardless of age, making the best use of the workforce. Second, the cotton stick with 666 powder, plug the hole, due to contact with 666 powder, stomach poisoning, fumigation three kinds of role, when the larvae pull the dung sticky 666 powder can kill or fumigation death. In addition can also use carbon disulfide and DDT and other chemical control. (2) Before adults lay their eggs, apply the trunk of the trunk with lime water. The preparation of lime 10 parts, sulfur 1, 40 parts of water. Can prevent adult eggs.
