021-How 澳门赔率和威廉希尔对比Plants Work with Linda Chalker-Scott (The Science behind Plants)

γ Grow,,澳门威廉希尔

了解植物是如何工作的,是我园艺行业和澳门赔率和威廉希尔对比业余爱好中最自由的经历之一。

虽然我会一直好奇,especially when it comes to 澳门赔率和威廉希尔对比plants,我永远不会知道这一切。Nor do I want to.有什么好玩的??

然而,having a sound basis from which to draw for determining cause and effect has allowed me to have a beautiful landscape and garden,全有机的,我只需要很少的干预就可以做到这一点。

Author of How 澳门赔率和威廉希尔对比Plants Work with The Garden Professors

琳达·乔克·斯科特站在他旁边”园林教授”Holly ScogginsJeff Gillman和Bert Cregg(L-R),

Fortunately,我们有像琳达·乔克·斯科特这样的人,酸碱度。Dto help us understand how 澳门赔率和威廉希尔对比plants work.

在这个播客中,澳门威廉希尔we touch on a few of the subjects she addresses in her book,植物如何澳门赔率和威廉希尔对比工作;植物惊人行为背后的科学。澳门赔率和威廉希尔对比

As an Associate Professor of Horticulture and extension urban horticulturist at Washington State University,她以科学为基础的写作和谈论方法是我最爱她的品质之一。

根与真菌:一个重要的关系

The relationship thatroots have with beneficial bacteria and fungi,尤其是菌根,让琳达相信我们不应该,曾经,在我们的土壤中使用杀菌剂。Fortunately,home gardeners rarely need to resort to this for vegetable and ornamental gardens.

然而,lawns often succumb to fungal diseases.我们很快就找到了解决这个问题的化学方法。虽然它可以解决应用杀菌剂的问题,目前还没有看到的是,土壤下更重要的有益真菌生物也被破坏了。

菌根是我们今天谈论的最有益的真菌之一,因为它与植物的根形成了共生关系。澳门赔率和威廉希尔对比天然存在于健康土壤中。真菌附着在植物的根部以提取营养物质。澳门赔率和威廉希尔对比In return,the mycorrhizae fungus adds a vast network of thin root extensions to help draw in more nutrients and water to the 澳门赔率和威廉希尔对比plant.

One of the biggest inhibitors to mycorrhizae's ability to benefit 澳门赔率和威廉希尔对比plant roots is excess phosphorus and salt-based synthetic fertilizers.

底线是土壤越健康,the more abundance of mycorrhizae and the benefit it provides to aiding 澳门赔率和威廉希尔对比plant nutrient and water uptake.

The Primary Ways 澳门赔率和威廉希尔对比Plants Defend Themselves

澳门赔率和威廉希尔对比Plants work in mysterious ways.因为它们是不动的,无法躲避捕食者,他们有内置的防御机制,可以非常有效。

Monarch caterpillar feeding on milkweed

植物自卫的方法之一是使用对许多昆澳门赔率和威廉希尔对比虫有毒的化合物。这里看到的乳草就是这样一种植物。澳门赔率和威廉希尔对比帝王毛虫没有被吓倒,因为它是它们唯一的食物来源。

毒药-某些植物中的毒素意味着许多昆虫不能以它们为食澳门赔率和威廉希尔对比。一个例外是帝王卡特彼勒。在吃树叶的时候,通过摄入毒素,it makes the caterpillar less attractive to predators.

驱避剂澳门赔率和威廉希尔对比Plants can emit scents that are found to be unattractive to certain pests.它的工作方式可防止对设备造成任何损坏。澳门赔率和威廉希尔对比

Deterrents –澳门赔率和威廉希尔对比Plants that act as deterrents may allow minor damage to plants,但是害虫遇到的不愉快经历有助于阻止它们进一步造成损害。

乙烯气体是植物在压力下的常见排放物。澳门赔率和威廉希尔对比Some insects are drawn to this and attack the 澳门赔率和威廉希尔对比plant.其他捕食性昆虫respond to the same emissions,知道被捕食的昆虫被吸引到同一个工厂是因为气体的排放。澳门赔率和威廉希尔对比

了解根区域的宽度

我们经常听说树根延伸到排水沟,or edge of the tree canopy.但这只是故事的一部分。典型的根系远远超出了滴水线,通常超过2-3倍,如果可以的话。

根系的深度很大程度上取决于土壤。浅根区在压实或扰动土壤中很常见。然而,in undisturbed,排水良好的土壤,roots can extend very deeply.

水,营养物,氧气是根的三个关键需求。根区膨胀性增长的决定因素是可利用的数量和对每个根区的访问。

在这三个关键需求中,氧气是决定根系生长深度的主要因素。更多的氧气进入土壤深处,更可能的根源将随之而来。

清除集装箱植物的土壤澳门赔率和威廉希尔对比

Removing the soil medium from 澳门赔率和威廉希尔对比plants and trees before planting is counterintuitive.It flies in the face of what we've been taught for years.最佳实践建议我们这样做。

树根尽可能长出来。但是在一个容器里,they become bound and can't fix themselves.因此,we have to change the confirmation of the root pattern before 澳门赔率和威廉希尔对比planting.

The media in a container is often soilless and not the media we want to introduce to the native soil.因为它是不同的,roots tend to stay around it and fail to explore beyond it.

种植的目标是尽早在原生土澳门赔率和威廉希尔对比壤中生根。

A good alternative is to buy bare root 澳门赔率和威廉希尔对比plants.While bare root trees and shrubs are typically smaller and may take a little while longer to establish,一旦他们这样做了,它们将起飞并最终建立在一个更可持续的环境中。That usually happens by the third year.

The Wiggle Test

A good way to know if your tree is establishing below ground is the"wiggle test."Every month or so,lightly wiggle the trunk.Over time,you will find it becomes stiffer.That is the best indication that roots are settling in and the 澳门赔率和威廉希尔对比plant is alive and well.

staked trees

打木桩通常是不必要的做法,可以使树变弱。另外一个后果是,当支撑线过长时,会损坏躯干和四肢。

立桩植树会阻碍树木的生长。这是一种应尽可能避免的做法。Allowing a tree to move with the wind makes it stronger and quicker to establish.

如果你发现需要立桩,be sure to remove the supports within a few months to minimize damage to the tree and bark.

Does Flower Color Deter Certain Pests??

在最近的一次观察中,琳达注意到一种植物上的一些花没有被碰过,而另一些却被毁坏了。澳门赔率和威廉希尔对比在这种情况下,白色的花被砍掉了,而粉红色的花则没有被碰过。

其工作原理是,深色的花朵可能会因为重金属与色素的结合而变得不可口。土壤酸碱度也在结合潜在的有害生物不具吸引力的成分方面发挥作用。

覆盖火山——没有我们想象的那么糟糕

地膜火山

Mulch volcanoes piled high around tree trunks has been the source of controversy for years.New research now refutes many of those concerns when using appropriately sized mulch.

我们大多数人都会同意,覆盖火山看起来很可怕,而且受到了不好的批评。But,它真的那么糟糕吗?Perhaps not.覆盖物能掩盖种植不善的罪恶吗?澳门赔率和威廉希尔对比Does the mulch hurt trees??

New research yet to be published shows the mulch doesn't harm trees but can actually help trunk wounds heal faster vs.当暴露。

Arguments for not creating mulch volcanoes is the excessive depth of the mulch and contact of the mulch with the tree trunk.然而,the main problem appears to be in the type of mulch used.

Finely textured mulch is harder for moisture and air to penetrate.粗糙的,chunky mulch has proven to offer great water and gas transfer.

在单独的研究中,厚厚的一层粗糙的木屑覆盖物既能抑制杂草,又不会以任何方式伤害土壤。The key is coarse mulch and texture vs.finely textured deep mulches.

So while volcano mulching may not be bad,覆盖物的选择似乎是真正的问题。

How 澳门赔率和威廉希尔对比Plants Tell Time

树在我们注意到变化之前就开始为冬天做准备了。As nights become longer,它们开始了生物过程,通过测量光与暗的比例,帮助它们为秋季和冬季做好准备。

As day length shortens and temperatures become low enough,树木显示出它们的变化。但这是一个由两部分组成的过程。Unlike temperature,夏至夏日减少的日照量是最可靠的时钟树,用来开始秋季和冬季的准备工作。

There's one exception: urban trees.由于人造光,a tree can be tricked to think it's still summertime because the artificial light masks the fact that days are growing shorter.

需要光才能发芽的种子

小种子往往是光休眠。它们必须有光才能发芽。随着我们的到来,new weeds germinate because they are brought to the soil surface,and light triggers germination.

地膜能很好地阻挡阳光照射到地表的新种子。
