查询词典 defoliation

This dissertation studied the overcompensatory responses of cotton,Gossipium hirsutum L. plants to leaf loss, square loss and cell sap lossand the changes in some physiological and biochemical contents with timein the case of overcompensation. The artificial defoliation, early squareremoval and aphis colonization were used as three types of simulated ornatural herbivory. The target of this study is to elucidate thephysiological mechanism of cotton plant overcompensation for insectherbivory.

本文以棉花为实验材料，采用人工去除棉花一部分叶片、花蕾及接种棉蚜的方法，分别模拟昆虫食叶、食蕾及吸汁为害等三种为害方式，研究棉花对于失叶、失蕾及损失细胞汁液所产生的超补偿作用，及一些生理生化代谢随棉花发育时间进程变化的情形，以期较为系统地从多个方面阐明棉花对于虫害超补偿作用的生理学机制。

Till that time,so-called me, so-called Dao, aren't they just like the defoliation in autumn or the deadwood in winter?

到那个时候，所谓的自我，所谓的大道，它们不就像是秋天里的落叶或冬天里的枯枝麼？

I like the recession of autumn, can satisfy oneself to see the sorrow of defoliation once.

我喜欢秋天的萧条，能满足一下自己看到落叶的悲伤。

When the attack is severe and allowed to continue, repeated defoliation will occur, resulting in a weakened plant.

Defoliation as a way of disturbance has an important influence on micro-patch of L.

4刈割对羊草微格局的影响体现在斑块数量、面积和周长上。

Defoliation is achieved by adding elements which have a greater affinity than iron for oxygen.

Branches exposed to sun by defoliation are extraordinarily susceptible to sunburn and will surely die.

分行暴露在阳光落叶非常容易晒伤，并肯定会死的。

Experiments were carried out. The effects of defoliation on photosynthesis, dry matter translocation, grain yield and water use efficiency were investigated with different defoliation degrees and different soil water levels.

该文通过水分胁迫条件下不同程度脱叶和不同水分条件下脱叶-不脱叶的田间试验，研究了减少蒸腾器官对冬小麦光合特性、干物质转移、产量和水分利用效率的影响。

In this paper, as a case of Karamay, we have studied on space-time changement of soil quality in oasis of arid area. We measured quality for different land use types and years in same type by combinativing field sampling for Karamay in Xinjiang and analysis in laboratory, which is directed by former theory of soil quality. Then we did integrated evaluation of soil quality for different land use types, and had drew some conclusions as followed: In four land use types, the soil bulk density of layers(0～15cm) for farmland and tree land is bigger than the other land use types.The organic matter of every layer in manpower Tamarix Bulrush land is bigger; organic matter of Tamarix Bulrush land release efficiency nitrogen which result ration of C/N is higher; total nitrogen of all layers in farmland variety great as being effected by mass use of nitrogen in agriculture; deadwood and defoliation of tree、shrub and bulrush pooled in 5cm layer to result that quick nitrogen is the biggest among all layers. The total salt of nature shrub tree land for every layer being bigger than farmland explain that nature shrub thee land strongly stand salt and farmland for basification in this area; that the nutrient of face layer is bigger than the ground layer may be explained by that vegetation gather nutrient to be stored in deadwood and defoliation.

本文对以克拉玛依为例，对干旱区绿洲土壤质量的时间空间变化进行研究，在有关土壤质量的研究理论指导下，通过田间调查取样和室内分析相结合的方法，对新疆克拉玛依市农业开发区的不同土地利用方式及同一土地利用方式下不同利用年限土样土壤理化性质进行测定，从而对新垦绿洲不同土地利用类型土壤质量进行综合评价，结果如下：四种土地利用方式中，农地、乔木林地表层(0-15cm)土壤容重较大；各土层人工柽柳芦苇地的土壤有机质含量均较大；柽柳芦苇地的有机质在矿化过程中所释放出有效氮，导致柽柳芦苇地的C/N比例较高；受到农业耕作使用大量氮肥的影响，农地各土层全氮含量变异较明显；乔木、灌木及芦苇的枯枝落叶主要集中在5cm范围之内，导致几种土地利用方式类型下该层土壤速效氮最大；天然灌木林地的土壤总盐在各层均较大，其次是农地，说明天然灌木林地的高耐盐能力，以及该区农业生产用地的土壤盐碱化程度较重。

Results indicated that full defoliation was the key measure to autumn reflowering,and from late August to early September was the optimum defoliation time in Heze,Shandong Province.Chemical defoliators like abscisic acid and ethephon could advance the flowering time of three autumn-flowering cultivars 2—6 days,and had a better effect on the reflowering quality and leaf development than artificial defoliation.

结果表明：全株脱叶是实现牡丹二次开花的关键措施，在山东菏泽地区以8月下旬至9月上旬为适宜的脱叶时间，脱落酸、乙烯利等化学脱叶药剂处理使秋发1、2、3号品种的二次开花时间提前2～6 d，显著提高了植株二次开花质量，尤其是明显促进了二次叶片的发育。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
