栽培模式对南方丘陵红壤旱地春玉米生理生化特性及产量的影响
Effects of cultivation models on physiological and biochemical characteristics and yield of spring maize in hilly red soil upland of southern China
摘要
Abstract
Objective] To provide a scientific basis for high-yield cultivation of spring maize, Zea mays L. , in southern hilly red soil.[Method]Film mulching cultivation was coupled with organic fertilizer and increasing K fertilizer, using conventional fertilization and open cultivation as the control. Yield, physio-logical and biochemical characteristics of spring maize were researched in different cultivation models.[Result]Conventional fertilization +organic fertilizer +K fertilizer + film mulching cultivation ( TOK ) resulted in the highest yield, increasing 3. 4% compared with conventional fertilization + bare land ( CK) . One hundred-seed weight of TOK increased 14. 9%, 15. 1% and 20. 4% respectively, compared with conventional fertilization+organic fertilizer+film mulching cultivation(TO), conventional fertiliza-tion+K fertilizer+ bare land( TK) and CK. Each drought index showed TOK>TO>TK>CK. The net photosynthetic rate ( Pn ) in each growth stage showed TOK >TO >TK >CK. There was a maxmum change range of Pn among all treatments in maturity,which was 43. 62%.[Conclusion]TOK is one of the better cultivation models for spring maize in hilly red soil upland of southern China, which can achieve high yield by increasing Pn and drought resistance.关键词
