Abstract

The invention discloses a seed coating agent suitable for blanket-shaped seedling raising of rape and application thereof. The seed coating agent is prepared from the following components in parts byweight: 1-5 parts of cyazofamid, 1-5 parts of imidacloprid, 1-5 parts of uniconazole, 80-100 parts of an auxiliary agent and 0.1-0.5 part of boron. The coating agent is suitable for mechanized seedling raising and mechanized transplanting of oilseed rape, is simple and easy to operate, can effectively prevent and inhibit survival and propagation of clubroot pathogenic bacteria by aiming at variousdiseases and insect pests of blanket-shaped seedling raising under high-temperature and high-humidity conditions, and effectively reduces and blocks the diseases and insect pests from the source, andthe prevention and treatment efficiency is higher; the coating agent can effectively improve the root growth capacity of blanket-shaped seedlings by inhibiting root diseases, and blanket-shaped grownseedlings and mechanized planting of the blanket-shaped grown seedlings are facilitated; when diseases are prevented and treated, uniconazole and boron are added, excessive growth of seedlings is inhibited, and nutrients and trace elements which are deficient in soil are fully supplemented; and common diseases and insect pests such as rape damping-off, downy mildew, clubroot and aphid in the blanket-shaped seedling raising stage can be effectively prevented and treated.

Description

technical field [0001] The invention belongs to the field of seed coating agents, and in particular relates to a seed coating agent suitable for raising rapeseed seedlings in a blanket shape and an application thereof. Background technique [0002] Rapeseed is an important oil crop in my country. Traditional rapeseed cultivation requires manual seedling cultivation and transplanting, which is labor-intensive and time-consuming, and is not conducive to mechanized operation. It has become a bottleneck restricting the development of rapeseed production in my country. The mechanical transplanting technology of blanket-shaped rapeseed seedlings jointly developed by Yangzhou University and Nanjing Agricultural Mechanization Research Institute of the Ministry of Agriculture uses plastic plugs to cultivate blanket-shaped rapeseed seedlings, and then quickly transplants them with a rice transplanter, which solves the problem of artificial seedling transplanting. The problem of high l...
