鹿泉市基层农技推广体系改革与建设示范县项目已实行四年了,期间,我市出台了系列强农、惠农政策,蔬菜种植面积逐年扩大,尤其北部休闲农业区涉及的李村、大河2个乡镇的滹沱河滩沿线,更是发展迅猛。种菜离不开科学的方法,据我们调查,多数菜农对于治虫、肥水调控、整形等措施掌握较为熟练,而对蔬菜病害的辨别与防控相对滞后,认识上模糊,导致应对上乏力。实践表明,能否取得丰产,苗期管理是重要前提,培育出无病壮苗,才能为后期打好基础。所以,正确区分与防治苗期病害,是蔬菜生产至关重要的一环。作者所说的苗期,包括育苗期和定植后苗期两个阶段。这一时期,外界气候变化频繁,既是蔬菜病害高发期,又是情况最为复杂困扰时期,往 Luquan City grassroots agricultural extension system reform and construction of demonstration counties project has been implemented for four years, during the city introduced a series of strong agriculture, benefiting agriculture policy, vegetable planting area expanded year by year, especially in the northern leisure agriculture area involved Li Village, Two towns along the river Hutuo River, but also the rapid development. According to our investigation, most vegetable growers are more skilled in controlling insects and worms, regulating fertilizers and shaping, while their identification and control of vegetable diseases lags behind. Their understanding is vague, resulting in a lack of response. Practice shows that the ability to obtain high yield, seedling management is an important prerequisite for nurturing disease-free seedlings, lay the foundation for the latter part. Therefore, the correct distinction and prevention of seedling disease is a crucial part of vegetable production. The author refers to the seedling stage, including seedling stage and post-planting seedling stage. During this period, the frequent climate change in the outside world is both a period of high incidence of vegetable diseases and the most complicated and disturbing period.
