2011年3月19日星期六晴今天我买了三只小鸡,它们全身长满了淡黄色的绒毛,圆圆的脑袋两侧各有一只黑溜溜的小眼睛,那尖尖的、粉红色的小嘴"唧唧喳喳"地叫个不停,柔弱的翅膀时而扑扇几下,似乎想要飞起来。它们中的一只有时会钻到同伴的身子底下,把同伴一下子背起来。有时又调皮地站在同伴的身体上,把同伴压得直不起身子。它们 相似文献

Potential growth of two widely-grown hybrid rice varieties in the Jinhua district of Zhejiang Province, Shanyou63 for mid-rice and Xieyou46 for late rice, was simulated using a crop growth model of WOFOST. Parameters of the rice growth in WOFOST were calibrated through field experiments from 1999 to 2002 in Jinhua. The potential yield simulated with WOFOST was about 12 t/ha for Shanyou63 and 10 t/ha for Xieyou46, which are in good agreement with the highest recorded yield obtained in this area. Under farmers practice, current yield is about 7.5 t/ha for Shanyou63 and 6.5 t/ha for Xieyou46. There is a gap between the actual rice yield and the potential yield for these two hybrid rice varieties grown in this area. The attainable target yields were set to 70% to 75% of their potential yields for the two varieties. A recently developed software "Nutrient Decision Support System (NuDSS)" for irrigated rice was used to optimize nutrient management for these two rice varieties. According to NuDSS, the optimal fertilizer N requirement for the target yields was about 150 kg/ha for Shanyou63 and about 120 kg/ha for Xieyou46, which were only about 70% of the fertilizer N application under current farmers' practice. Comparing with farmers' practice, there is great potential to increase actual rice yields and to reduce fertilizer N use rates by improving rice crop management practice in Jinhua. 相似文献

近日闲翻《钓鱼》杂志11月下期,读到江苏丰县史为林先生所作《对酒泡小米的质疑》一文时,不觉心动,多看了两遍。文中对酒泡小米在垂钓中实际产生的作用发生了怀疑,特别是“酒”对于招鱼和诱食所起的作用发生怀疑,并通过简单的试验加以证明。但最后并没有一个明确的结论,仅作为一个疑问提出来供大家探讨。在这里,我就试着来参与一下。 相似文献
