Abstract:

In order to study the effects of different fertilizer combinations on the improvement of tobacco leaf quality in Zhucheng, field experiments were carried out for three consecutive years by establishing integrated technologies such as organic fertilizer instead of chemical fertilizer and new biological pesticide instead of traditional pesticides. The results showed that compared with the conventional application method, the high proportion of organic fertilizer and biological pesticides had obvious effect on the integrated optimal use of medicinal fertilizers. In 2023, field-scale demonstrations were carried out, the agronomic traits of tobacco leaves were improved, the control effect of pests and diseases was significantly improved, and the output value was increased. A demonstration area for organic tobacco production was set up in a typical ecological area in Zhucheng, and the field demonstration showed that the quality and safety level of tobacco was significantly improved. This study can provide an empirical reference for the high-quality development of tobacco leaves in Weifang and even Shandong tobacco areas.

Key words: integration of pesticides and fertilizers, Zhucheng organic tobacco, bio-organic fertilizer, new biological pesticides, tobacco quality safety
