介绍了特优航2号参加福建省区试、生产试验以及在龙海示范种植的表现。调查了特优航2号不同产量水平的产量构成,明确有效穗与产量的相关最密切,对产量直接通径系数最高,对产量贡献率最大;其次为每穗总粒数,有效穗与每穗总粒数对产量的贡献率占4个构成因素总贡献率的86.39%。据此提出特优航2号高产栽培技术。
Introduced the Teyouhang 2 to participate in the Fujian provincial test, production test and demonstration of the performance of Longhai demonstration. The yield components of Teyouhang 2 at different yield levels were investigated. It was found that the correlation between effective panicle and yield was the highest, the direct path coefficient to yield was the highest, and the contribution rate to yield was the highest. The second was panicle number per panicle, The contribution of the total number of grains to the total yield of the four components accounts for 86.39% of the total contribution. Based on this, Teh-Hang 2 high-yielding cultivation technology was proposed.
