断根

So the depth(20-40cm)of fertilizer application could be as best depthfor delaying the senescence of flag leaf and root system and gainning highyield and high efficiency in dry land wheat.5 The effects of deep cultivation-root cutting on the senescence after an-thesis and yield had been studied in dry land wheat of high yield.the best ef-fect obtained from treatments by deep cultivation-root cutting in beforewinter stage,next by the treatment in the starter stage treatment and in con-trol,lastly by the treatment in the before winter stage and starer stage.

由此认为延迟旱地小麦根系与旗叶衰老并获得高产的施肥深度应在20-40cm左右。5深耘断根对旱地高产小麦花后衰老及产量的影响进行了研究，以冬前深耘断根最好，起身期深耘断根与对照次之，冬前和起身期都深耘断根效果最差。

Usage: Complement nursing that part uses, coordinate an instrument being put into use having an effect to eliminate the fat granule and understand crinkle seal, smallpox seal and chromatosis healing.

使用要领：局部使用的补充照顾护士，共同仪器使用有效断根油脂粒且断根愈合的皱印，痘印及色素沉着。

But after about a month to restore the root system, the leaves of nitrogen, phosphorus and potassium contents in treatment 5, 6, 7, 8, 2 gradually higher than the control. This is because the absorption of fertilizer during this period shown to promote on the elements, and with the passage of time the processing elements continue to be reduced to a leaf until the latter part of the growing season is also higher than the control.3.The pH value in rhizosphere soil of treatments poplar plantation were lower than that in non-rhizosphere soil, but the content of organic,available nitrogen, phosphorus, potassium, utility cuprum and utility zincum were all higher than those in non-rhizosphere soil.

但是经过大约一个月的根系恢复，处理5、处理6、处理7、处理8、处理2叶片中的N、P、K逐渐高于对照，这是因为施肥对元素的吸收在这一期间开始表现出了促进作用，并且随着时间的推移各处理中元素含量持续降低至落叶，直至后期的生长季节也高于对照。3、各处理的杨树林地根际土壤pH值均低于非根际土壤，而有机质、碱解氮、速效磷、速效钾、有效铜和有效锌的含量均高于非根际土壤，与其它处理相比，80cm两侧断根施肥处理的根际土和非根际土壤速效养分含量最高，差异达显著水平。

The deep cultivation-root cutting in before winter stage would increasethe weight and ratio of root system in middle and lower layer,the resultswould decrease the root redundancy.

冬前深耘断根可增加中、下层根系的重量和比率，降低根系生长冗余性，控制最高总茎数，提高成穗数及成穗率，使籽粒产量中来自花后光合器官输送的比例增加，从而使产量提高，因而在旱地高产麦田应推广冬前深耘断根。6研究了降水量对旱地高产小麦耗水规律及产量的影响，拔节前降水多且占比重高，土壤供水量及占比重少，拔节后降水量减少且占比重低，土壤供水量及占比重高，利于在旱地高产麦田形成高产。

The effects of different cutting-root methods (time of the cutting, distance of cutting surface to stem base, and the numbers of cutting surface) and K top-dressing measures at later growth stage on K content in leaves of flue-cured tobacco plants were studied.

从断根时间、断根部位、断根数量、断根时追钾与否及追施钾素的形态等方面研究了不同处理及其组合对烤烟烟叶含钾量的影响。

By no K top-dressing, earlier cutting roots is better for improving K content for the low leaves and middle leaves; but cutting roots at the same time of topping is benefit for improving K content for up leaves.

在不追施钾肥的情况下，对下部和中部叶片而言，现蕾期断根有提高含钾量的趋势。而对上部叶片而言，打顶时断根有提高含钾量的趋势

By K top-dressing, cutting roots soon after decapitation is the best time for improving low leaves and up leaves'K content, but cutting roots by squaring is the best time for improving K content in middle leaves.

在追施钾肥的情况下，打顶时断根对提高下部叶和上部叶片含钾量的效果最好，但中部叶含钾量则是现蕾时断根处理为最高。

G. cutting roots from 4 surface on the position 20cm away from the stem base nor cutting roots too near from stem base e.

若断根数量太多（如距茎20厘米处4面断根），或断根位置距茎基部太近（距茎基部10厘米处1面或4面断根），都不利于叶片含钾量提高

It should be mentioned that the application of root cutting should based on genotypes characteristics of winter wheat, for example, we could get better effects by root cutting which the wheat cultivars has more effective tiller number.

研究结果也表明，不同基因型对断根的反应不同；因此，在生产实践中应根据品种特性施行小麦断根技术。

Attacking a Canada thistle (actually of Eurasian origin and a regular entry in "worst weeds of North America" lists) with hoe or plow, for example, may destroy the plant's aboveground growth but leaves the soil full of severed bits of fleshy root, each of which may sprout a new plant.

例如，如果用锄或者犁的办法清除加拿大蓟草（这种实际上是来自欧亚地区的草年年都出现在&北美最顽固草类&的名单上）的话，则只会消除地表以上的部分，却在土壤中留下了无数的断根，而每个断根都会长成一棵新的植株。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
