苗木澆水學問不少,這些要點你都了解嗎?

發布日期:2019-03-12 瀏覽次數:58

水,是植物生長的必需因素之一,水分的多寡和吸收的時間

對苗木的生長和發育有著至關重要的影響。因此,在苗木培育和養護的過程中,

如何科學合理地保證苗木水分的有效供給是一項重要的工作。


1、新栽苗木

對于新栽的苗木要連續澆三次保活水,

以小水慢灌的方式令植物根部吸足水分,然后壓實土壤,

扶正、固定苗木,加速植物根系與土壤的密接。尤其北方

一些早春干旱、風多雨少、地面蒸發大的地區,新種樹木必須經常澆水,而且要澆足灌飽。


2、生長期苗木

苗木生長期一般可以分為花前、花后、

花芽分化三個時期。在苗木開花前及時澆水,可以解決其萌芽、

開花、新梢生長時所需的水分,同時還能預防春寒、晚霜的危害;而多數苗木在

花謝后半個月左右會進入新梢生長期,此時必須保證水分供給,才不會抑制新梢的

生長;苗木花芽分化期若水分不足,則會嚴重影響果實生長

花芽分化,這對觀花、觀果類的苗木尤為重要。

3、休眠期苗木

一般秋冬和早春之間,大多苗木處于

相對休眠和半休眠的時期。在秋末或冬初土壤

即將封凍之前要澆封凍水,以提高苗木的越冬能力;

待到早春土壤將要化凍之時,又要及時澆解凍水,

以達到預防早春干旱、提高土溫、促進樹木萌芽和增強耐旱能力的作用。

那么,澆水時又有哪些要點呢?

01、水量多少

苗木的澆水量受很多因素的影響,主要包括樹種、規格、

生長狀況以及土質、氣候等,需要具體情況具體分析。通常情況下,

苗木的澆水量以達到土壤持水量的60%-80%為宜,在干旱時期或

土質不好的地區應適當增加。

一般來說,喬木比灌木、常綠樹種比落葉樹種、陽性樹種比陰性樹種、

淺根性樹種比深根性樹種的需水量大;速生、生長期長或觀花、觀果

觀葉的苗木水分需求量較其他樹種更大;苗木生長期比休眠期的需水量大。

02、水源選擇

苗木澆水的水源可以是河水、池水、溪水、井水,也可以是自來水,但絕不能使用受污染的廢水。

03、澆水方式

常見的澆水方式有人工澆灌、機械噴灌、地面灌水、噴灌等,

目前大多地區是以人工澆灌為主。澆灌之前要先松土,保證土表不板結,

令水分容易滲透。澆水時應一次灌飽灌透,若采用小水淺灌的方式容易

造成苗木根系向淺層生長,不利于苗木的抗風、抗旱能力。待突然表面

稍干后,可及時加蓋細干土或中耕松土,減少水分的蒸發。
