✓ located verbatim in the source · abstract, characters 577–603 Other claims from this paper (15) Observation Ear number and grains per ear are the main factors determining population yield above 15 t per hm2 in high-yield spring maize. Observation The yield structure for populations above 15 t per hm2 has an ear number of (7.08-9.60)x10^4 ears. Observation The yield structure for populations above 15 t per hm2 has 477-654 grains per ear. Observation The yield structure for populations above 15 t per hm2 has a thousand-grain weight of 324.7-388.7 g. Observation The yield structure for populations above 15 t per hm2 has a grain weight per ear of 168.9-234.0 g. Observation A reasonable population structure has LAImax above 6.5. Observation A reasonable population structure has mean LAI of about 5. Observation A reasonable population structure has LAI at harvest above 3.5. Recommendation The ideal yield structure for tall large-ear cultivars is 67,500-75,000 ears per hm2, 610-640 grains per ear, thousand-grain weight about 380 g, 220-240 g grain weight per ear and yield above 15 t per hm2. Recommendation The ideal yield structure for medium-height small-to-medium-ear cultivars is 75,000-97,500 ears per hm2, 520-600 grains per ear, thousand-grain weight 340-355 g, 180-220 g grain weight per ear and yield above 16.5 t per hm2. Intervention effect Increased planting density increased mean crop growth rate and total grain number per unit area. Intervention effect Increased planting density thereby raised yield. Intervention effect After densification, mean net assimilation rate (MNAR) decreased. Mechanism Structural potential tapping mainly through densification, where population gains exceed the loss in individual performance, achieves high yield above 15 t per hm2 (gain-loss compensation yield increase). Recommendation The authors identify functional potential tapping, giving combined gain in population structure and individual function (differential compensation yield increase), as an important route to further raise yield.
