根株

In "Avatar," every blade of grass, every cloud in the sky, every vine in the jungle existed digitally and had to be stored somewhere.

在《阿凡达》中，每一根草、每一朵云、每一株藤蔓都以数字形式被储存在某个地方。

The result was a dizzying amount of data—every blade of grass, every cloud in the sky, every vine in the jungle existed digitally and had to be stored somewhere.

其结果就是无比巨大的数据量，因为几乎每一根草、每一朵云、每一株藤蔓都以数字的形式被储存在某个地方。

With the Sand culture method, influences of different magnesium levels (0%、50%、100%、150%、200% and 300%) was explored to the wheat seedlings of different stages. Many targets such as plant height, root length, biomass, content of chlorophyll, activity of root, RGY, RGR and ratio of root to crown of the wheat were mensurated at the time of 7d, 15d and 30d of two leaves stage of wheat seedlings after their endosperms were removed at different magnesium levels.The results showed that different magnesium levels had unlike influences over the wheat seedlings.

以小麦为试材，采用砂基培养的方法，在镁浓度分别为对照组的0%、50%、100%、150%、200%和300%的营养基质上，培养剔除胚乳后的二叶期小麦幼苗7d、15d及30d，并分别测定该3个时间段小麦幼苗的株高、根长、地上部和地下部的生物量、叶绿素含量、根系活力以及相对生长速度、相对生长速率和根冠比等指标，研究不同供镁水平对不同时期小麦幼苗生长速率的影响。

The test results of acute toxicity were examined with Pearson's degree of fitting. The results indicated that the silkworm was extremely sensitive to Chlorantraniliprole. The median lethal concentration (LC50) was 4.0905×10^(-3) mg/L and median lethal dose (LD50) was 1.1435×10^(-8) mg/larva for the 3rd instar newly exuviated larvae. No toxicity was observed when normal concentrations of Chlorantraniliprole were used to fumigate the silkworm rearing room. Both irrigation and leaf spraying with 1.25×10^(-4) mg/L Chlorantraniliprole solution showed strong systemic transmission properties in root, leaf and whole plant. The residual toxic period of this insecticide to silkworm was very long. Mulberry leaves sprayed with 1.25×10^(-4) mg/L Chlorantraniliprole solution could still cause 100% mortality of the 3 and 5 instar larvae after 60 d. Furthermore, toxic reaction was very quick. The poisoning symptoms emerged within 1~5 h after feeding on the poisonous leaves. The poisoned larvae experienced such symptoms as stopping ingestion, remaining still, vomiting slightly and body atrophy sequentially, and died ultimately.

食下毒力试验结果经Pearson拟合度检验表明，氯虫苯甲酰胺对3龄起蚕的食下致死中浓度(LC50)为4.0905×10^(-3)mg/L，致死中量(LD50)为1.1435×10^(-8)mg/头；药剂在常规浓度下对家蚕无熏蒸毒性；1.25×10^(-4)mg/L稀释药液对桑树根灌和喷叶处理，表现极强的根部、叶部和全株性内吸传导特性；药液对家蚕的残毒期很长，1.25×10^(-4)mg/L稀释药液田间喷雾桑叶，间隔60 d后采叶饲喂3龄和5龄蚕的死亡率均为100%，且中毒反应极快，添食毒叶后1~5 h出现中毒症状，经停止食桑、静伏、少量吐液、蚕体萎缩等过程后陆续死亡。

But I have often stared casually at little thing of this universe, a bird, a fish, a flower, or a small plant, and even at a bird's feather, a fish's scale, a flower petal and a blade of grass, and realized how Mother Nature has also created it with all her great skill and wisdom and energy.

然而，我却时常不经意的观察身边的一些小事物，一只鸟，一条鱼，一朵花，或一株小的植物，甚或鸟的一根羽毛，鱼的一片鳞，一个花瓣和一片草叶，因为大自然用同样的智慧和技巧创造了它们。

The results showed that different tillage patterns could improve soil water storage,the soil laer of no-tillage was covered by straws between 0 to 20 cm held water(4.542±0.894)×10~5 L/hm~2;Under no-tillage with full-straw mulching average soil temperature at 0～20 cm decreased...

结果表明：不同的保护性耕作措施均可提高土壤水分含量，其中留茬旋耕处理的土壤贮水量最高，达(4.542±0.894)×105L/hm2；在玉米播种前期及苗期，免耕覆盖处理降低土壤温度1~2℃，而整个生育期留茬旋耕处理与传统耕作处理的土壤温度相近；苗期，留茬旋耕处理的玉米株高、根长、鲜重和干重均优于其它处理，促进了玉米的生长发育；不同的保护性耕作措施均可提高玉米的产量，与传统耕作相比可增产
