弯曲穗型杂交粳稻高产生理基础及配套栽培技术

Physiological Basis of High Yield and Corresponding Cultivation Techniques of Cured-Panicle Japonica Hybrid Rice

对弯曲穗型杂交粳稻的高产生理基础进行了分析。结果表明,弯曲穗型杂交粳稻具有生物产量高、增产潜力大、光合叶面积大、叶片功能期长、抗逆性强(抗倒性强、抗病性强、耐瘠薄性强、耐旱性强)、适应性广等特点。针对上述特点提出弯曲穗型杂交粳稻栽培配套技术为适期早播早插,培育壮秧;建立理想的群体结构;合理运筹肥料;科学管水;及时防治病、虫、草害。

The physiological basis of cured-panicle japonica hybrid rice was analyzed.The results showed that the cured-panicle japonica hybrid rice cultivars had the characteristics of high yield,large yield increasing potential,large photosynthetic leaf area,long leaf functional period,strong stress resistance,wide adaptability,etc.The corresponding cultivation techniques of cured-panicle japonica hybrid rice cultivars were as follows: early sowing and transplanting,cultivating strong seedlings,establishing ideal population structure,reasonable fertilizer application;scientific water management,controlling disease,pest and weed timely.
