A****0 发帖数: 72 | 3 I disagree. Liquefaction is not the reason. You have to have strong
vibrations/earthquakes to liquefy the soils since they were compacted.
I believe the reason of soil losing compactness is because of frost heaving
action. The fines in the fine sand make the backfill susceptible to frost
action. Your company probably only checked the soil density at the top. The soils below frost line should meet the required 95% compaction requirement.

不会画图.
2. 以工程为例, 本地工作经验是基本要求, 国内的5年可以不用考虑了, 如果你以后有

3. 鬼子比较讲究工程标准, 懊洲标准要玩熟.
4. 话说回来, 再难也有人找到工作,再容易也有人找不到工作, 还要看自身实力和运气.
5. BRISBANE&PERTH机会比较多.

词:粮食产量 十一连增 粮食安全 进口 撂荒
蒋高明
刚才,中国科学报记者就国家统计局公布粮食十一连增问题,采访笔者对此问题的
看法。国家统计局12月4日发布公告,2014年全国粮食总产量达到60709.9万吨(12142
亿斤),比2013年增加516万吨(103.2亿斤),增长0.9%。我国粮食总产量实现“十一
连增”从2010年开始,每年相对前一年的增幅分别为2.9%,4.52%,3.2%,2.1%,0.9%
。这个问题非常复杂,数据肯定是没有问题的,但关键是我们的粮仓里是否有这么多粮
食。现在需要澄清的问题是:
第一,中国18亿亩耕地撂荒的有多少?播种季节减少的耕地有多少?
第二,原本不缺粮食的省份,许多也开始缺粮,其原因是什么?
第三,既然已经产出了6亿多吨粮食,为什么还要那么多的进口?
其实,当前农业的问题,是在资本市场打压下,农民种地积极性下挫严重,老人妇

i******d 发帖数: 565 | 23 地点在VA,前房主几年来一直没有维护,使得房子前面的草坪很差,杂草占了一半以上
。后面的草坪目前还好,不需要太大的维护。房前的草坪大概3500尺,土层很少,下面
都是碎石头,估计当初builder直接将草铺在碎石头上。在版上做了一点考古,想采用
下面的方案,求建议和补充:
1。用割草机将草割到尽量短,割掉的草打包带走,并清理草坪。
2。从HD租一个areator,将草坪全部过一遍。
3。浇水,starter fertilizer,撒草籽。
4。从HD购买top soil,好像价格是$1.37/cubic ft,准备采用2"厚度,3500尺草坪需要
580 cubic ft 或者22 cubic yard,花费要$790。请问2"厚度是否合适,花这个钱是否
值得。
5。撒草籽以后,铺上top soil,然后每天浇水,一天大概6次,保持土地一直处在潮湿
状态。好像如果从HD买塑料薄膜铺在top soil上会省很多水,请问这样可行吗?
6。等草长出来再过一个月以后,开始采用weed killer杀死草坪上的杂草。请问这样可
行吗?是否需要我现在用round up杀掉所有的草。我担心这样做的话 |

可以好好看看发黄的叶片是什么状态。叶片上有什么特别的病症没有?
比如说,spot或者mosaic,有这些的话,可能是细菌,也可能是病毒。如果是真菌的话
,叶片上可能会有菌丝。
再一个可以在发黄那一片把草皮铲一块起来,看thatch里有没有虫子。
三,也可能是soil compact,你很久很久不打孔,不铺沙,草得根系无法呼吸。
或者那一片over irrigate了。
总之原因会有很多,不要一上来就soil test,白花钱。 |

你新种的草可以活过冬天和春天,但是,如果夏天炎热干旱,很可能因为Top Soil含砂

your soil is compact.
Aeration will likely bring weed seeds up to the surface for later
germination. Especially if you have dropped pre-emergent, you should not
disturb the soil for it to be effective.
Even if the soil is moderately compact, adding organic matter (e.g. top
dressing with compost) and spraying diluted baby shampoo every few weeks is
still better than mechanical aeration, IMHO. |

你这个计划有两个问题。第一,杀死草用挖是不行的。
最好的办法还是用 roundup。 roundup 不影响铺新的草,
roundup 需要喷到叶子上吸收才有效果。到土壤里就没有
用了。我家草坪就是先 roundup 很多次,然后撒种子种的。
第二,翻地的时候会把杂草种子给翻出来。浇水会发芽出
杂草。其实不用翻地也可以的。翻地以后,需要等几个月,
地里要浇水,这样让土落下去,整理平整。同时让杂草发芽,
继续用 roundup 杀。搞几个回合表面杂草种子消耗掉。
不需要自己去搬 top soil 的。草长起来有 4 inch 深的根,
你的 top soil 要 4 inch 很贵很贵的。搬运回来的 top soil
同样有杂草种子的问题,需要浇水,发芽,round up 处理。 |

S*A 发帖数: 7142 | 46 有些网友问我这个草坪的 seeding 计划是如何的。
我就大概在这里讲一下。注意的是,我的方式和网上或者视频
介绍的方式不太一样。我会简单讲下我为什么要这么做,主要
都是为了减少杂草发芽破坏新草坪的成长。还有我会尽量简化
掉不需要的步骤,减少资金投入。 反正我的方法是至少
有一个成功例子的。
先决条件,如果这些条件不满足,就不要考虑用这样的计划。
1)草坪要有自动的 irrigation system. 可以是临时的,但是
浇水要均匀。最好有可以编程一天超过 3 次喷水的那种控制
器。
2)要可以忍受草坪有几个月的时间完全秃掉,没有草的状态。
如果你不可以忍受,或者 HOA 不允许,那就不要考虑这个计划。
准备工作要有几个月。工作量其实不大,但是要细致。
3)可以接受使用 round up 来全部灭掉杂草。
使用工具:
1)drop spreader
2)pre-mix sprayer,撒农药和液体化肥。

具体计划:

S*A 发帖数: 7142 | 47 太赞实干派。
我的功力不够,只能帮你大概读一下。你的 CEC 和 OM 都还不错。
所以土壤还算不错的。 pH 低比较多。你的 base pH 是没有给吗?
base saturation 里面没有数字是你漏了还是没有给?其他还不错。
我不是很确定铁在 ph 5 里面是不是到了毒性的浓度。
我只能读到比较肤浅的,你几乎肯定需要把 pH 调高,撒 Lime。
好在 pH 低是可以调的, pH 高的话就很难调。
我建议你把 soil test result 贴到
http://aroundtheyard.com/soil/
注意读版主置顶的第一篇 Posting A Soil Test for Interpretation
然后等待版主 andy10917 给你更加详尽的解读。
andy10917 是真正的顶级高手,我比 Andy 弱多了。

基本就是按照SCOTT的网站指示来的。

夏天除了剪草就不用做什么了,做什么都没有用。好草长的慢,野草长的快。
但是注意剪草的时候留最高或者次高的一档,让好草扎根深一点。草剪短就毁了,我家
前面的草坪去年被劳模减的非常短,然后就开始变秃了。
(2)
秋天开始,OVERSEED,就是把杂草清一清,然后不好的地方补种种子。补种子的时候用
那个SCOTT的LAWN SOIL比较管用,先刨松了土,撒一层LAWN SOIL,撒种子,盖一层
LAWN SOIL.要是天冷了或者干,弄点那种干草或者絮絮一样的东西当被子还是挺好的。
树下补适合SHADE的种子。
(3)
冬天杂草都死了,好事,可是好草也怎么不长。撒了一次SCOTT TURF BUILDER
WINTERGUARD. 撒肥料的时候要注意别贪多别撒重了,会烧草,烧出一条黄黄的... 阅读全帖 |

n***t 发帖数: 8357 | 50 没有; 还看得见草籽在TOP SOIL上。
很郁闷。。。
新房的TOP SOIL很少,底下大多是CLAY,不知会不会有影响。但我又加了TOP SOIL,按
道理不会。 |
