钦州地处桂南,气候炎热,雨量丰沛,高温高湿,番茄易受青枯病危害,具体防治措施如下:一、种番茄的田地实行十字花科和禾本科作物轮作3年以上,最好与禾本科进行水旱轮作。二、选用抗病能力强的品种,如抗青19号、夏星、粤红玉、L402、洪抗1号、秋星等。以增强植株对病害的抵抗力。三、加强栽培管理,采用高畦栽培,并施用充分腐熟的有机肥或草木灰或五四○六3号菌500倍液,以改变微生物群落;亩施石灰100～150公斤,调节土壤 PH值。四、用青枯病拮抗菌 MA-7、NOE-104于定植时大苗浸根,也可在发病初期用硫酸链霉素或72％农用硫酸链霉素可溶性粉剂400倍液或农抗“401”500倍液、25％络氨铜水剂500倍、12％绿乳铜乳油500倍液。
Qinzhou is located in Guinan, the climate is hot, abundant rainfall, high temperature and humidity, tomato susceptible to bacterial wilt, the specific prevention and treatment measures are as follows: First, the cultivation of tomato fields crucifer and grass crop rotation for more than 3 years, the best Drought and drought rotation with grass. Second, the selection of strong disease-resistant varieties, such as Anti-Green 19, Xia Xing, Guangdong Hongyu, L402, Hong anti-1, autumn stars. To enhance plant resistance to disease. Third, to strengthen the cultivation and management, the cultivation of highland barley, and the use of fully matured organic fertilizer or ash or 500 times the number of bacteria 46,063 to change the microbial community; Mushi Shi lime 100 to 150 kg, adjust the soil PH value. Fourth, with the bacterial wilt antagonistic bacteria MA-7, NOE-104 in planting seedlings dip root can also be early in the pathogenesis of streptomycin sulfate or 72% of agricultural streptomycin sulfate soluble powder 400 times the liquid or agricultural anti-401 "500 times, 25% copper aqua regia 500 times, 12% green milk EC 500 times.
