不同海岛棉品种产量及水分利用效率研究

Study on Yield and the Water Use Efficiency to different Island cotton

通过对5个海岛棉品种产量与水分利用效率的分析研究,结果表明,不同海岛棉品种各生育期土壤含水量存在差异。不同海岛棉品种产量、水分利用效率存在极显著差异。新海21是节水型品种,能够较充分的利用有限的灌溉水,在干旱半干旱地区具有强大的优势。

Though Studying on yield and the water use efficiency to different Island cotton . The results show that there are distinct difference in soil water content among different Island cotton ; yield and water use efficiency of different Island cotton have distinct difference among various varieties. New sea 21 can save water, can use limited irrigation water, so it has advantage of power in arid and semi - arid region.
