Effects of Different Cultivation Modes on Production and Agronomic Traits of Rice

This study aimed to reveal the effects of different cultivation modes on production and agronomic traits of rice.The results showed that: 1)The highest yield of both rice species were under film mulching cultivation in glebe(HF),which compared with film mulching cultivation in paddy field(SF),dry farming cultivation(HBF) and conventional cultivation(CK),the difference reached significant level.The yield sequence of super hybrid rice combination 88S/1128 under different cultivation modes was HFSFHBFCK.The yield sequence of elite inbred rice Xiangwanxian 17 was HFHBFSFCK.2)The main factor of high-yield rice under HF could attribute to effective panicle number,seed-setting percent and 1 000-grains weight were increased.The dry-matter accumulation,tillering number per plant,leaf area index and SPAD of both rice species under HF were significantly higher than which under CK,SF and HBF,but plant height under HF,SF and HBF were lower than which under CK.
