所有這些優點刺激遼寧水稻種植面積經久不衰地擴大。The above results suggest that the photosynthesis of the hull may contribute to grain filling and the development state of the hull may directly affect grain filling
以上結果表明,水稻在結實過程中,穀粒充實所需的物質至少有相當一部分來自於谷殼的光合作用,並且谷殼發育的好壞亦能直接影響穀粒的充實。One of the most important features of the data in table 1 and figure 1 is that rice yields become less responsive to the addition of fertilizer as fertilizer use increases
表1和圖1中的數據所表現的一個重要特性是:隨著肥料施用量的增加,追加的肥料所帶來的水稻產量的增加量逐漸減小。Consequently, deep roots are more important than shallow roots in examining drought resistance of rice variety
所以在檢驗水稻品種抗旱性上,深根比淺根更重要。Rice research institute has kept plentiful and diversified genetic resources of rice
