悬赏分:0 | 提问时间:2008-11-26 13:44 | 提问者:pzyzzh009
推荐答案
栽培技术 用扦插繁殖为主,亦可嫁接或压条繁殖。
    扦插繁殖:于5月下旬至8月上旬,利用当年抽生的新梢做插条,具2个节,在节下20cm处截断,若把切口浸入(10-50)×10\-6吲哚丁酸溶液中2-3h,可促进生根。扦插用土为园上加30%珍珠岩,置于半阴处,约3-4星期生根。
    嫁接繁殖:多于2-3月间在室内进行。接穗带1个节,并在节下2cm处切断,运用劈接法。压条繁殖:于4-6月间进行。培育1-2年后,于春、秋季,选背风向阳处,以带土球的植株定植。

扦插繁殖:
扦插可在短期内获得较大的苗。 

   (1) 插条的选取:嫩枝扦插于每年6~7月采集半木质化嫩枝, 剪成10~15 cm长的插穗, 上剪 口距芽1 cm左右平剪, 下剪口距芽0.5 cm斜剪; 硬枝扦插则于每年落叶后土壤结冻前, 选取 直径0.5 cm左右、长10~15 cm的休眠枝, 剪穗方法同嫩枝扦插。 

   (2) 插条处理:扦插前, 插穗用ABT 1号生根粉溶液进行预处理。嫩枝插穗的处理浓度为5 0×10-6, 浸泡时间为0.5~1 h; 硬枝插穗处理浓度为100×10-6, 浸泡时间 为1~2 h。浸泡深度为距插条下剪口3~4 cm。 

   (3) 扦插:以河沙或河沙与土的混合物(土/沙=1∶1)为扦插基质, 充分整平。处理后的 插条直插入基质3~4 cm, 压实, 及时喷、灌水以保持基质和插条湿润。扦插后20~25 d便 可生根, 生根后即可移植。 

   3.压条繁殖: 

   压条繁殖法是在爬山虎的茎藤不与母体分离的状态下将其压入土中, 使压入土中的茎节处发 根, 然后 再剪断形成数个独立于母体的新株的繁殖方法。压条生根前, 茎藤所需的水分、养分全部由母株提供。 此方法优点是成活率高、管理简便、幼苗生长旺盛。缺点是繁殖率相对较低。

   (1) 压条时期:生长各期均可进行, 一般以3~4月爬山虎的体内汁液开始流动和7~8月枝 条成熟后的两个时期进行压条效果较好。其它时期压条虽然也能成活, 但生根较慢。 

   (2) 压条方法:将匍匐于地面的茎藤, 自基部保留40~60 cm的暴露生长段外, 其 余部分均可埋入配好的基质。基质成份: 优质厩肥∶锯末∶表土为1∶1∶1或2∶1∶1。基质 覆盖厚度一般为15~20 cm。覆盖后应经常浇水保持湿润以利发根、出芽。 

   (3) 断剪成苗: 压条15~20 d, 新芽便可自被埋压的节处长出。待新芽长至40~50 cm时 , 新根已生长良好。此时可在新芽下方10~15 cm处挖开小段土埂, 在节间剪断, 便得一株新 苗。剪后立即覆盖剪口, 使剪口尽快愈合。3~4 d后, 新苗便可以移苗出圃, 定植或保留在 原位继续生长。

    爬山虎可种植在阴面和阳面,寒冷地区多种植在向阳地带。幼苗生长一年后即可粗放管理,在北方冬季能忍耐—20℃的低温,不需要防寒保护。 
  移植或定植在落叶期进行,定植前施入有机肥料作为基肥,并剪去过长茎蔓,浇足水,容易成活。

Use Trellis for Screening


Use Trellis for Screening

One of the popular uses of trellis today is to use trellis panels as screening to provide privacy. Trellis screening is great by a deck or patio as it provides some privacy but also allows light through to create a pleasant dappled shade. In the example shown, this custom made trellis screen provides the owners of this property some privacy while sitting on their front patio, instead of being on show to anyone walking by.

DIY - Privacy Screens, How To by Aubrey

Our Privacy screen project is done, but here are the how tos on how to do it yourself! Remeber, we wanted to build some screens (a) to hide the chain link fence. (Bleh, I think it's ugly)(b) to get some privacy from our neighbours garden and(c) to add some more weight to this side of the garden, as the other side got a full fence last summer. It seemed "uneven" to have all the wood on one side of the yard. Here is the DIY post.
aubrey


Some have e-mailed me to ask for a how-to on how Aubrey did our privacy screens. My apologies for the delay or non response - the reason is - I had no idea how to explain what Aubrey did! I just came up with the idea, and he figured out, as he always does, how to make it happen. So I asked him to write it out for me, and so here is a little post from Aubrey explaining how to do your own privacy screens. - Linds

------------
STEP 1: MAKE THE DECISIONS
The first step was to make all the decisions...How many you'll be putting up, how tall they will be, what they will look like. Essentially you need to have a complete picture of them in your mind. I highly recommend marrying someone who is very good at the "vision thing", it makes this part much easier. Lucky for me, I did, so the design is all Lindsay (I tend to only disagree with her when the dollar figure gets really big or when something is going to be really difficult.) *

screen

STEP 2: SHOPPING TRIP
The next step was to buy the wood and concrete. Here's what we used to make 1 screen

(1) 4x4 posts, 2 for each screen (and we made sure they were long enough to go 4 feet underground.)
(2) post toppers (2 per screen)
(3) 2x4's (enough length for the top and bottom of each screen)
(4) square lattice (one 4' x 8' sheet per screen)
(5) plenty of nailing strips (in my case 12 per screen)
(6) 2 bags of quick setting concrete per post (We used Rapid Post - a type specifically made for fence posts that set very quickly and did not require premixing.)

STEP 3: DIGGING THE HOLESOnce I had all that on hand, I measured out where the centre of each post would be needed and started to dig. The bags of cement have specs on them so I just did what they said. I dug the holes to have an 8 inch diameter and I went 4 feet down. (you want to get beneath the frost line)
garden1
(Because I knew the holes wouldn't be filled right away because I needed a break, I covered the holes so that rain wouldn't fill the holes up)

TIP: If you have more than two holes to dig, don't do them by hand. My hands were silently screaming at me for a few days afterwards, and the blisters were not pretty either. Places like Home Depot and Lowes rent powered augers for less than $100 per day. It's worth it. After recovering from my dig day, it was time to set the posts.

STEP 4: CEMENT TIME 

I put each of the posts in their holes and measured to make sure they were the right distance apart. TIP: We chose to make things easy - we made the screens 4 feet in width (the 2 posts 4 feet apart) so I would only have to cut the lattice for height. (Lattice comes in 4ft widths) If you wanted thinner screens, then you would have to cut the lattice some more.

The info on the cement bags claimed that you could simply put the post in the hole, add their mixture and the right amount of water, and then set the post to be straight without using supports to keep them exactly where they needed be. I didn't believe them, I still don't. And I was not going to be digging those holes again so I took some extra precautions.

garden2

I followed the instructions about adding the concrete and water around the post and mixing it up a bit it with a long stick but I used my level and screwed on supports to keep them in place.

016

Before I started the next set of posts I made sure to install the 2x4's on the first. Aside from framing the top and bottom of the screens they also helped keep the posts the right distance apart and prevented them from shifting while the concrete set.

025

It was a lot of work to move around those bags of concrete, buckets of water, and set the posts myself, so I would recommend having someone there to help. I managed to do all 3 sets in one afternoon which left us with 3 vertical rectangles in our yard. All that was left to do was fill them with lattice. That was the job on day 3.

STEP 4: FILLING IN THE FRAME, FINAL DAY
On the inside of the frame, towards the back I installed the nailing strips. I made sure they were the same distance from the back edge of the frame and went all the way around the rectangle not leaving any gaps (might as well look nice from the neighbour's yard too.)
Next I cut the sheets of lattice to fit between the top and bottom 2x4's (side to side already fit thanks to a bit of preplanning.) Once they were propped up in place I used more nailing strips all the way around pinching the sheets of lattice in place.

The final piece of the project was to chop the tops of the posts off (at the same height of course) and add the post toppers.

Here are the screens completed - we've used planting inbetween the screens to fill in the spaces to hide the fence.

All told, we spent well under $300, I spent 3 afternoons in the sun, and another of Lindsay's visions looked excellent in real life too.

 Common Name: Columbine

A series of hybrids that has stood the test of time. 'McKana Hybrids' come in a wide range of pastel colors, many of them bicolors. They are prized for their large, showy flowers with long, widely flared spurs. So beautiful they sell on sight!

Aquilegia is especially lovely when allowed to naturalize in shady, woodland borders. They also have excellent potential as cut flowers, lasting up to 2 weeks in a vase.
Origin: Not Native to North America

至于耧斗菜的中文名称的来历一直未能查到。
耧(音:lóu),播种用的农具,前边牵引,后边人扶,可同时完成开沟和下种两项工作:~车。~犁。~播(用耧播种。亦称“耩地”)。耧斗菜使用的“耧斗”这个词在现成的词典中一直没找到。从形象的角度来看,在北方农村经常使用一种用来耧草的耙子,一般是用一根根8号铁丝,按一寸左右的等距离排列,穿进两根横的木条中心固定成,着地一头专门用于耧草的铁丝则弯成钩,与耧斗菜的花的内弯的短距或长距极其相似,也许这就是耧斗菜中“耧”之来历,至于“斗”嚒,应该考虑花的形状了:此花上大下小为一斗状,于是两者结合谓之曰“耧斗”,尽管形状似漏斗,但未见正式文章中称“漏斗菜”或“漏斗花”。



辣椒

辣椒的栽培技术
1、播种育苗


冬季大棚生产辣椒常因病害发生而欠收,尤其是炭疽病和细菌性斑点病更为常见。为了防治炭疽病和细菌性斑点病,可结合浸种催芽进行种子消毒,具体做法是:先将种子用清水预浸10-12小时,再放入1%硫酸铜溶液中浸泡5分钟,然后用清水洗净种子,进行催芽;或用40%福尔马林150倍液浸种15分钟,洗净后催芽。催芽温度以25-30℃为宜,以变温催芽效果最好,即白天25-30℃,晚上16-20℃。这样比恒温催芽出苗快而且整齐。


播种前要准备好育苗土和营养土。播种后至出苗前要注意温度管理,以提高温度为主,一般以白天25-30℃,晚上20℃为宜;出苗后应适当降温,以25℃左右,晚上16℃左右为宜。育苗期间应注意水分的管理,棚内湿度太大,应利用中午时间进行通风,一来降低棚内湿度,二来提高棚内的氧气浓度。只有在缺水时,才轻喷一次。


2、整地与定植


定植前应翻耕棚土,施用基肥,具体做法可参照茄子栽培部分。


整地后,为了减轻栽培过程病虫害的危害,于定植前进行大棚消毒,具体的做法是:按每立方米空间用硫磺5克、80%敌敌畏0.1克和锯屑10克,混匀点燃;封闭一昼夜后,打开棚门,进行通风;再关闭棚门,提高棚温,以待定植。


定植以垄作为主,每垄定植两行,株距30-35厘米,1/15公顷(1亩)定植2500株左右。定植后应及时浇定植水,以利还苗。


3、田间管理


定植初期不通风,保持高温高湿,以利还苗。还苗后逐渐进行通风锻炼,白天最高温度保持26-28℃,夜间保持15-20℃。随着天气转暖,要逐渐加大通风。


定植前浇足底水,定植时浇定植水。在还苗过程中,若干较干,可于上午在叶面喷水(可加0.4%磷酸二氢钾,以促使提早还苗)。春前定植还苗后,高垄栽培的浇1-2次水即可,非高垄栽培的直到门椒膨大时才进行浇水。浇水时结合追肥,追肥每1/15公顷(1亩)施硫酸铵25千克、硫酸钾10千克。此后根据生长情况决定浇水、追肥的次数和数量。


为提高大棚辣椒的着果率和产量,可采用植物生长调节剂。据试验结果,以2,4-D和番茄灵效果最好。使用方法是:浓度为2×10-5的2,4D,在开花时涂花;浓度为25×10-6的番茄灵,在开花时喷花器。生长后期将植株下部的老叶及细弱的枝杈除去,以节省养分,加强通风透光。 来源: 中国蔬菜网

种花笔记2011

6月中约了政府的water efficient lawn and garden visit,得到几点建议:


  1. add compost to garden bed
  2. add mulch to exposed soil in garden
  3. pruning general rules: 
  • cut anything dead or dying at anytime, 
  • prune after flowering
  • no more than 1/3 at a time (lilac)
  • prune close to the branch's collar 这个我要特别注意,以前我随便剪枝,剪得离节过高
几个我不清楚的植物名称:
前院的树是Norway Maple 不是native tree, invasive. 
树下面是burning bush, Euonymus
树下面的一颗PINE有一侧枯黄,建议砍掉,种别的
窗下面的灌木建议剪到和前面的PINE齐高,从根部剪掉一些branches,boost它长得更浓密
丁香开花后,要修枝,前院和后院的丁香不是一个品种
丁香旁边的sandberry严重被snail 入侵,需要剪到所有被被snail 入侵的branches,看能不能活下来;春秋后去买专业杀虫喷剂。

后院的篱笆墙不要爬得太高,攀到屋顶下面的金属雨槽,会损害雨槽。
铁丝莲(clematics) top needs sun while roots need to be cool,
铁丝莲有3种剪枝技术,我家这个看来是在新枝上开花的品种:new growth clematis. This clematis blooms later in the season on new wood, which is on stems grown in the current season. Pruning is done in February and March just as leaf buds are seen on the lower sections of the plant. Remove all dead material above the buds. (more info here http://laptopgardener.com/?p=735
今年点的籽(seeds) 五月Victory day,太晚
另外还辨别的后院几种野草,建议把现有的植物养好,再养新的。

另外,玫瑰长虫了,叶子被啃光了,需要杀虫
