According to the under-forest ultra-short corn expanding planting method and application, through
system integration in the aspects of variety selection, forest stand structure optimization, water and
fertilizer integration, mechanical matching,
ecological safety management and the like, stable planting and high yield of corn in an under-forest environment are achieved; and the annual availability and the unit area comprehensive income of the forest land are obviously improved. According to the method, the adaptability of the variety and the forest environment is particularly emphasized, and the risk of poor growth and development of the corn and the influence on forest growth are reduced by controlling the
plant height and the ear height of the corn;
light energy utilization is optimized through strip-shaped
layout and light window design, intelligent water and
fertilizer management and ecological prevention and control measures are combined, and the stability of corn growth and development and yield is effectively guaranteed. Meanwhile, the method is compatible with two product routes of
silage and grains, assists the integrated development of planting and breeding, has high regional adaptability and popularization value, provides reliable
technical support for a forest-grain or forest-grass
compound system, and has remarkable ecological, social and
economic benefits.
