Effect of Water-nitrogen Interaction at Tillering Stage on Aroma, Grain Yield and Quality of Aromatic Rice
摘要
Abstract
The purpose of this study was to investigate the water-nitrogen interaction at tillering stage on aroma, grain yield and rice qualities. A field experiment was conducted with three conventional aromatic rice cultivars,Non-gxiang 18(indica),Basmati 385(indica) and Y-14(japonica),three water treatments(W1,well-watered,4-6 cm;W2,intermittent irrigation,the minimum water potential was-10 kPa;W3,moderate soil drying,the minimum water potential was -20 kPa) and three nitrogen treatments:(N1,0 kg/ha;N2,30 kg/ha;N3,60 kg/ha,at tillering stage) were used in this study,to evaluate the effects of the water-nitrogen interaction at tillering stage on 2-AP con-tent in brown rice,grain yield and rice qualities. The results showed that water-nitrogen interaction had an signifi-cant influence on 2-AP content in brown rice. The treatment W3 and N3 significantly improved the 2-AP content, Under W3N3 treatment,Nongxiang 18,Basmati 385 and Y-14 achieved the highest 2-AP content,up to 17. 69, 30. 60,23. 15 ng/g,respectively,followed by W2N3. W2N3 treatment harvested highest grain yield than other treat-ments,except for Y-14. At tillering stage,wet irrigation and using the right amount of tillering nitrogen(60 kg/ha) can improve grain yield and 2-AP content in brown rice together.关键词
