What's worse, they think that the temperature condition is not necessary for seeds to come into leaf and that plants can also grow well without fertilization.

学生对於植物生长的另有概念包括将根与茎的名词定义错误，认为植物是「先长茎再长根」或「先长果实，后开花」；并对植物器官的功能不熟悉；缺乏植物的「花」、「果实」具有传宗接代等繁殖概念；「温度」条件对种子发芽而言是非必要的；植物有「施肥」就长得更好，没有施肥也不会怎样；知道植物可以用种子繁殖，除了种子以外可以繁殖的器官学生多数只看过落地生根用叶子繁殖，缺乏更多的实际经验。

Gentleman orchid drenchs rot the root dies after water, the likelihood has the reason of two respects, it is basin earth too wet, because gentleman Lan Xihuan is loose,understand the edaphic requirement that appear, once basin earth is medium moisture is too big, its bulky flesh pledges the root arrived to will come in October between November, already entered stop to grow or grow very slow condition, do not need how many moisture, need to hold basin ground only wet can, drench water causes those who rot the root is unavoidable too much; 2 it is you drench when water, flow into the phyllome center of plant the dirt that will have smudgy part along with all the others, and at this moment water of blade rising bad news is less, sewage accumulating is inside Xie Cong, also can choose sodden heart sodden root.

君子兰淋水后烂根死亡，可能有两个方面的原因，一是盆土过湿，因君子兰喜欢疏松通透的土壤条件，一旦盆土中水分过大，其粗大的肉质根到了10月至11月间，已进入停止生长或生长很慢的状态，不需要多少水分，只需要保持盆土湿润即可，淋水过多造成烂根是在所难免的；二是你淋水时，将会有脏污成分的尘土等一并流入植株的叶丛中心，而这时叶片蒸腾耗水较少，脏水积在叶丛内，也会选成烂心烂根。

The results showed that "Green Drought Resistance agent NO.1, NO.2 and NO.3" harmonized ear number, spike number and 1000-seed weight of winter wheat in dry land, they have good yield-improving effects. The drought-enduring experimentation showed that with the raising of the PEG density, the restrain that burgeon and rootage got on each treatment were more obvious. The drought resist of burgeon ratio, length of bud, rootage ratio, number of root and length of root treated by GDR1 was better than check's.

结果表明：GDR1号、GDR2号和GDR3号抗旱剂较好地协调了旱地冬小麦的穗数、穗粒数、千粒重，具有较好的产量效应；耐旱性试验表明，随着PEG浓度的增高，各处理发芽和生根受到抑制作用越明显，GDR1号处理的发芽率、芽长、生根率、根数和根长的抗旱性优于对照；不同土壤水分条件下绿色抗旱剂GDR1号的出苗率、幼苗和根系生长与不同PEG浓度条件下的处理结果相一致。

Their common structure and annual changing pattern of mycorhizae are as follows: Fungi infect and form endomycorrhizal structure with plants throughout the latter's grown period, and hyphae exist in the cortical cells of roots in the following four forms: Coffee-colored or yellow big peloton consisting of twisted hyphae; Dust-colored or yellow big peloton consisting of fragmentary hyphae; Colorless scattered hyphae; Orange or yellow small peloton with blurry hyphae.

发现四种杓兰的的菌根结构及其在一个生长周期中的动态变化有以下共同特征：在其成年生活期的各个时期，都有真菌入侵形成内生菌根结构，菌丝在其根部皮层细胞内有四种存在状态：咖啡色或黄色、菌丝扭结缠绕而成的大菌丝结；灰褐色或黄色、由片断菌丝组成的大菌丝结；无色、零散的菌丝；橘红色和黄色、菌丝形态模糊的小菌丝结。

Results showed that low contents of Cd has promotion effect on Oryza Sativa, but high contents of Cd has not obvious restrain on it. The total trend of distribution of Cd in Oryza Sativa is root＞stem＞shell＞rice. The relation between Cd contents in rice and total Cd in soil as well as availability Cd in soil has been investigated. The result showed that both the total Cd and the availability Cd had notably correlation with content of Cd to rice, and the critical point were CaCl2-Cd=0.71mg/kg, DTPA-Cd=1.34 mg/kg, EDTA-Cd=0.76 mg/kg, NH4OAc-Cd=0.77 mg/kg.

研究表明：低浓度的镉对水稻生长稍有促进作用，高浓度的镉对其生长并没有明显的抑制作用；镉在水稻植株中总的分布趋势为根＞茎＞稻壳＞糙米；用4种有效态提取剂（0.1 mol/L CaCl2、DTPA、0.05 mol/L EDTA和1 mol/L NH4OAc）浸提出的有效态镉的含量和土壤中镉总量与水稻糙米中镉含量均达到显著相关水平，并确定了它们的临界值分别为CaCl2-Cd=0.71 mg/kg， DTPA-Cd=1.34 mg/kg， EDTA-Cd=0.76 mg/kg， NH4OAc-Cd=0.77 mg/kg。

While ECM fungal inoculations showed no significant improvements on seedling performance of P.

结果表明，某些树种与特定类群菌根真菌的子实体出现有负相关，而三个类群的外生菌根真菌在克隆生长上的差异并不是子实体空间分布的决定因素。

Green leaves, like a pin stripes main vein from the leaves has been grown out of the final Linked leaves vein became a long Juanxu, Juanxu the bottom of one of the 10-centimetre-long "bottle", whatever the field through the lips, then there is a bottle phenomenon, This is the lid -- like bottles favorite insect leaf cages, fishing worms Capsule cones shaped, slightly lower expansion, and some like pig cage, so that pitcher plants.

嫩绿的叶子上，一根大头针般粗细的主叶脉从叶片上一直生长出来，最后连着叶片的叶脉成了一根长长的卷须，卷须的底部系着一只十余厘米长的&瓶子&，瓶口的唇向外翻，瓶子上方还有一片小叶，就像瓶子的盖子―――这就是爱吃虫子的叶笼了，捕虫囊圆筒形，下半部稍膨大，有些像猪笼，故称猪笼草。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
