日本的水田与诗意

一那是一条去山端的弯弯曲曲的道路,一条由木屋夹出的道路,从我住的北白川,去京大交流会馆,必定要经过的。樱花簇拥的木屋前,停着一辆辆汽车,五颜六色的汽车,在屋前屋后的树荫里掩映,疏水一直唱着歌,伴我行走。突然出现了一大片水田,在木屋中间?在房舍和路密匝匝的围堵之下?那是一片汪汪的绿水,宽阔的秧田,欢乐的蛙声,令我没有想到。     

水稻壮秧分蘖剂苗期抗冷效果初探

利用人工气候室在苗期施用水稻壮秧分蘖剂对水稻秧苗的形态及生理方面的表现进行了探讨。结果表明：水稻壮秧分蘖剂具有增加秧苗干物重,提高秧苗素质,降低电解质渗出率和提高脯氨酸含量的作用。同时增加了秧苗的分蘖能力和提高水稻产量。

试验研究了海水浸染对水稻秧苗危害的表现形式，分析了总结了这种危害的特征，并依试验结果提出了防治危害的措施。     

Intraspecific differences in effects of co-contamination of cadmium and

A hydroponic experiment was carried out to study intraspecific differences in the effects of different concentrations of cadmium (Cd)(0-10 mg/L) and arsenate (As(V)) (0-8 mg/L) on the growth parameters and accumulation of Cd and As in six wheat varieties Jing-9428, Duokang-1, Jingdong-11, Jing-411, Jingdong-8 and Zhongmai-8. The endpoints of wheat seedlings, including seed germination,biomass, root length and shoot height, decreased with increasing the Cd and As concentrations. Significant differences in seed germination, biomass, root length, shoot height and the accumulation of Cd and As were observed between the treatments and among the varieties (p ＜ 0.05). The lethal dosage 50% were about 20, 80, 60, 60, 80 and 20 mg As/L for Jing-9428, Duokang-1, Jingdong-11,Jing-411, Jingdong-8 and Zhongmai-8, respectively, and the corresponding values for Cd were about 30, 80, 20, 40, 60 and 10 mg Cd/L, respectively. Among the six varieties, Duokang-1 was found to be the most resistant to Cd and As toxicity, and Zhongmai-8 was the most sensitive to Cd and As co-contamination. The resistance of the six varieties was found dependant on the seedling uptake of Cd and As. Duokang-1 was the most suitable for cultivation in Cd and As co-contaminated soils.     

永不飘移的目标

有位哲学博士某次漫步于田野中沉思,发现水田当中新插的秧苗,竟排列得如此整齐,犹用尺丈量过一般.他不禁好奇地问田中工作的老农是如何办到的.
