Abstract
【Objective】The experiment aimed to provide scientific and theoretical basis and technical guidance for high-yield hybrid seed production in maize.【Method】 Funong 22 was selected to study technical guidance for the high-yield seed production and physiological index,in which 7 densities and 3 levels of chemical regulator were used.【Result】The results showed that the treating of 97.5 thousand plant/ hm2 and 675 mL/hm2 chlormequat chloride had the biggest production,which the production of living things is 31 102.5 kg/hm2,the grain weight is 185.03 g,economic coefficient is 0.58,the total photosynthetic power is 5 355.1 thousand(m2·d)/hm2,The average net photosynthetic rate was 6.31 g/(m2·d),the productivity of dry matter is 211.2 kg/(hm2·d).【Conclusion】 Chemical control can decrease the height of the maize and improve the productivity,direction and position of dry matter,increase the proportion of economic output and biological yield and transformation efficiency.Too sparse or too dense planting and too little or too much chemical control can both cause unfavorable effect on the construction of suitable group structure,thus reducing its economic output.
