Formula fertilizer for controlling yellow runt seedlings, stunt seedlings, and rusty spot red withered seedlings of crops

Abstract

The invention belongs to the technical field of agriculture and crop cultivation. The innovative points are that: a special fertilizer product is developed through reasonable proportioning by correctly selecting related trace elements and secondary elements; and the special fertilizer product is mixed with specific bioactive substances for use, so the effects of effectively controlling physiological diseases such as yellow runt seedlings, stunt seedlings, rusty spot red withered seedlings, grey seedlings and the like of the crops in coastal saline-alkali soil, Lixia River bottom land, yellow earth and sandy earth soil, and fish pond and crab pond soil in the Yancheng city can be exerted, the diseased seedlings recover as soon as possible, and the special fertilizer product has an obvious disease-controlling pesticide effect on a piece of paddy field mixed with bacteria, fungi or viral diseases, leaf color changes in 12 hours, and the obvious effects of controlling the diseases and promoting growth can be exerted in 48 hours. When used for preventing the seedling diseases, the special fertilizer product promotes the seedlings to grow strong, and protects the seedlings from diseases; and the disease control frequency of a pesticide can be reduced by about 50 percent.

Description

Technical field: [0001] Agriculture, planting, crop cultivation techniques. Background technique: [0002] Yancheng City is a large agricultural city in Jiangsu Province. Over the years, coastal saline-alkali land, Lixia River low-lying land, yellow soil sandy soil, fishing pond and crab pond land, in the period of vigorous growth of plants, especially rice, suffered from low temperature and cold damage, or drought and little rain , or under the influence of herbicides, yellow stiff seedlings, dwarf seedlings, rusty red seedlings often occur, and are easy to induce bacterial, fungal and viral diseases. The existing products on the market lack professionalism and pertinence for the above diseases Therefore, it is difficult to prevent during the growth and development of crops, and it is difficult to cure after the onset, which often delays the normal growth of crops, leads to yield loss, and threatens agricultural production.
