This course closely combines with the actual production of spring corn in Northeast China, and explains in detail the main technical links of corn super-high yield cultivation techniques. At the same time, it is emphasized that the high yield of corn depends not on a single technique, but on a modular, standardized and standardized cultivation technique system with a reasonable combination of multiple techniques. The course is mainly about the five technical links to realize super-high yield corn: soil cultivation technique, selection technique of excellent varieties, sowing technique, reasonable compact planting technique and fertilization technique.
