由于去年冬季天气以晴为主,气候温和,造成蔬菜大棚温度高、湿度小,这样的环境虽然对蔬菜生长有利,但也非常利于蓟马、螨虫、粉虱等害虫的生存和繁殖。入春以后,随着气温的不断回升,棚室环境将更有利于害虫的繁衍,加上越冬害虫的虫口基数比往年增大,粉虱、螨虫、蓟马等为害会进一步加重,为此,提醒菜农朋友千万不能掉以轻心,必须采取科学有效的防治措施。 Due to the sunny weather last winter, mild climate, resulting in high temperature greenhouse vegetables, humidity is small, although this environment conducive to the growth of vegetables, but also very conducive to the thrips, mites, whiteflies and other pests to survive and reproduce. After the spring, as the temperature continues to rise, the greenhouse environment will be more conducive to the proliferation of pests, plus the population of pests more insect pests than in previous years, whiteflies, mites, thrips and other damage will be further aggravated, therefore, Remind farmers friends must not be taken lightly, we must take scientific and effective control measures.
