Description

说明书 一种在荒漠和半荒漠环境中提高梭梭属植物直播苗和移栽苗成活率的方法 技术领域
本发明属于林业生态栽培学领域,涉及一种在荒漠和半荒漠环境中提高梭梭属植物直 播苗和移栽苗成活率的方法。 背景技术
黎科 (Chenopodiaceae)梭梭属植物, 全球共有 11种, 主要分布在地中海到中亚的广大 沙漠地区, 生长在流动沙丘、 半固定沙丘、 盐渍土及砾质戈壁。 中国有梭梭 Moxylon ammodendorn (C. A. Me. ) Bunge , 又称梭梭柴或黑梭梭)和白梭梭 Haloxylon persic讓 Bunge ex Boiss et Bushse)两种。 梭梭属超旱生小乔木, 呈高大灌木状, 植株高度一般 在 2〜3 m, 个别植株可高达 10 m, 树冠通常较稠密, 多呈半球状或近椭圆形。 在荒漠中郁 闭度较高的梭梭群落往往貌似森林景观, 故以往人们常将成片分布的梭梭植被称为 "梭梭 林"。 梭梭属植物在我国的分布面积约为 1170 X 104 hm2, 占我国沙漠总面积的 9%, 主要分 布在我国西北部的新疆、 内蒙古、 青海、 甘肃和宁夏等省的荒漠地区, 而白梭梭仅分布于 新疆北部。 梭梭抗逆性极强, 属强旱生一盐生植物, 生态幅度较广, 是一种耐干旱、 耐高 温、 耐盐碱、 耐风蚀的优良的防风固沙和生态保护植物。 此外, 梭梭木质坚硬, 火力强, 也是优良的薪炭材, 有 "荒漠活煤"之誉; 其当年生枝条富含营养, 是优良的牲畜伺料; 还是 "沙漠人参"一肉苁蓉的寄主, 肉苁蓉具有很高的经济和开发价值。 梭梭是我国西北 荒漠半荒漠地区珍贵的植物资源, 也是我国干旱荒漠区固沙造林面积最大的树种, 在这些 地区防沙固沙、 减缓荒漠化、 维护生态安全上具有不可替代的生态地位和重要利用价值。 然而, 因人为因素和环境恶化, 梭梭和白梭梭资源曾受到严重破坏, 一度处于渐危状态, 被列为国家濒危三级保护植物。所以, 加快梭梭属植物林的恢复与营建日益成为我国西北 生态建设的重要课题。
然而, 在解决梭梭属植物林地的自然恢复与快速营建时却面临很多困难, 其中一个关 键问题是梭梭属植物直播苗和移栽苗的成活率极低。大量的野外调查表明, 梭梭和白梭梭 原生地自然发芽和人工播种的幼苗成活率仅为 1%左右,而人工移栽的梭 1〜2年生梭梭幼树 其成活率也仅为 10%左右, 即春季大量自然出芽、 人工播种和移栽的幼苗从春到秋出现大 量死亡的现象。 以往人们认为, 造成这一现象的主要原因是梭梭和白梭梭原生地荒漠环境 的极端恶劣, 其中包括高温和干旱导致幼苗和幼树致死, 此外还包括风沙掩埋和动物啃食 等。但据我们项目组在准噶尔盆地古尔班通古特沙漠地区多年调查和研究的结果表明, 许 多梭梭和白梭梭原生地荒漠环境并不严重缺水, 即便是极端干旱的 6月中旬至 8月下旬, 60 cm以下的沙土层仍含有较丰富的悬湿水。梭梭和白梭梭一般在 3月中旬至 4月下旬发芽或萌 发, 由于春季雨雪较多, 致使浅层沙土含水丰富, 幼苗或幼树根系生长极快, 至 6月中旬 前根系长度一般可超过 60 cm; 6月中旬以后由于 60 cm以下的沙土层仍有悬湿水, 能基本 满足幼苗生长所需。 因此, 在某些荒漠和半荒漠地区, 干旱并不是导致梭梭属植物幼苗死 亡的重要原因。高温 (气温)也不是梭梭和白梭梭幼苗大量死亡的主要原因,实验研究证明, 在一定的水分条件下, 幼苗和幼树即便是连续几天处于 50°C的高温环境仍能够正常生长。 此外, 风沙掩埋和动物啃食的确能使幼苗致死, 但不是导致其大量死亡的主要原因, 梭梭 和白梭梭具有极强的抗沙埋再生能力。
根据我们多年调查和研究的结果表明, 荒漠和半荒漠地区地表层 (0〜2 cm)高温 50°C, 平均温度)是导致梭梭属植物幼苗大量死亡的关键和重要原因。 夏季我国西北地区 的荒漠和半荒漠沙漠腹地生态环境极为恶劣, 地表层温度时常可达 60°C以上, 极端地表层 温度可达 80°C左右。 例如, 新疆准格尔盆地古尔班通古特沙漠腹地, 每年夏季的 6〜8月干 旱少雨, 气温高, 地表层温度更高, 白天气温时常超过 40°C, 而地表层温度可达到 75°C左 右。地表层高温常使植物受到严重的伤害胁迫, 胁迫的感应部位就在植物茎基与地表接触 的部位, 植物由于受到地表层高温胁迫而发生显著的生理反应, 轻者地上部和地下部生长 缓慢或停滞, 重者直接导致其整株死亡。 沙漠植物如梭梭和白梭梭虽有很强的抗逆特性, 但其幼苗和幼树难以长时间耐受 60°C以上的地表层高温胁迫,正是这一原因使得在新疆古 尔班通古特沙漠腹地梭梭属植物天然实生苗、直播苗和移栽苗成活率很低, 不仅使该区域 以梭梭属植物为优势的群落被破坏后很难自然恢复, 也使得植树造林非常困难。 此外, 地 表层高温还会引起梭梭属植物的幼苗 (5年以下)、幼树 (5〜10年)和成年树(10年以上)时常 发生"夏休眠"现象, 导致其生长变缓或停滞, 从而使年有效生长期縮短, 年生长量减少。 有一个先例可充分说明地表层高温是导致梭梭和白梭梭幼苗幼树死亡的关键因素。仅在几 年前,新疆阿勒泰地区某县***在其辖区的卡拉麦里山自然保护区某公益林管护站周围 曾种植移栽了 3000亩梭梭和白梭梭, 此地是典型的古尔班通古特沙漠腹地生态环境。 为提 高梭梭和白梭梭幼树成活率, 他们采取根下灌水、 草网格防沙等措施, 唯独没有对梭梭和 白梭梭幼树进行免受地表层高温胁迫的防护,两年后 3000亩梭梭和白梭梭幼苗几乎全部死 亡。 以上例子说明, 如果要在我国西北地区的荒漠和半荒漠沙漠环境中大面积恢复和营建 梭梭和白梭梭生态林,首先要克服梭梭和白梭梭幼苗和幼树免受地表层高温胁迫的这一关 键难题。
基于这一原因, 申请人在中国发明专利申请 CN101965788A中提供了使用防护网罩对 梭梭属植物进行防护, 提高其幼苗成活率的方法。 但是在风沙强烈的荒漠和半荒漠地区, 采用防护网罩的方法存在如下缺陷:①遮阳网易破损、基部的沙易被吹走露出空隙和锚地 爪, 影响了防止小动物啃食、保湿、 防风沙伤害和掩埋以及降低地表层温度的效果。②遮 阳网面具有孔隙, 保湿效果相对较差。③遮阳网易破损、基部的沙易吹走, 每年的维护成 本较高。 ④防护网罩制作成本较高, 每个制作价格为 5〜6元, 且均需人工制作, 费时费 力。 发明内容
本发明的目的在于提供一种在荒漠和半荒漠地区大规模进行梭梭属植物林恢复和营 建过程中,显著提高其直播苗和移栽苗成活率的方法,解决梭梭属植物在荒漠和半荒漠地 区大规模恢复和营建过程中因频繁发生的极端地表层高温等逆境因子而导致的幼苗成活 率低, 以及因时常发生 "夏休眠"现象而造成的个体生长缓慢等关键难题。
本发明的目的可通过如下技术方案实现:
一种在荒漠和半荒漠环境中提高梭梭属植物直播苗和移栽苗成活率的方法,利用圆柱 形管件或中空子弹型管件对荒漠和半荒漠环境中的梭梭属植物直播苗和移栽苗进行防护, 具体方法包括:
(1) 圆柱形管件或中空子弹型管件的构造、 类型和规格: 所述的圆柱形管件适用于荒 漠或非流动性沙漠或沙丘上播种或移栽梭梭属植物苗,该圆柱形管件又可细分为直播苗圆 柱形管件和移栽苗圆柱形管件; 直播苗圆柱形管件的外直径为 9〜12 cm, 高 17〜20 cm, 管壁厚 0.25〜0.30 cm; 移栽苗圆柱形管件外直径为 6〜8 cm或 9〜12cm, 高 20〜30 cm, 管壁厚 0.25〜0.30 cm; 所述的中空子弹型管件适用于风沙较大的半流动沙漠或沙丘上移 栽梭梭属植物苗, 其上口外直径 3〜5 cm, 下口外直径 6〜12 cm, 总高度 40〜60 cm, 上 部收口部分高度 3〜8 cm, 管壁厚 0.25〜0.30 cm;
(2) 植物材料: 包括梭梭属植物种子及 1〜2年生幼苗;
(3) 实施时间: 梭梭属植物种子以及幼苗在当年初冬的 11月至翌年的 4月份播种或 移栽; (4) 实施方法: ①非流动性沙漠或沙丘上播种梭梭属植物种子时, 先将所述的直播苗 圆柱形管件的一端埋入或***沙土中, 地上留 12〜15 cm, 然后向地上部分管件的***堆 土, 堆土高度为 6〜8 cm, 使管件内外的地表平面错开 6 cm以上, 并使管件的上沿口距 离堆土面的上沿 4 cm以上,最后将种子播撒在管件内的沙土上并覆土 l cm左右;②非流 动性沙漠或沙丘上移栽梭梭属植物幼苗时, 先将梭梭属植物幼苗植入沙土中, 植深 40 cm 以上, 然后将所述的移栽苗圆柱形管件从上向下套住小苗, 并进一步***沙土中 5 cm, 最后向管件地上部分的***堆土, 堆土高度达 15 cm以上, 使管件内外的地表平面错开 15 cm以上; 以上两种圆柱形管件的使用状态图见图 3; ③风沙较大的流动性沙漠或沙丘 上移栽梭梭属植物幼苗时, 先将经选定株高达 70 cm及以上的梭梭属植物幼苗植入沙土 中, 植深 40〜60 cm及以上, 然后将所述的中空子弹型管件自上而下套住幼苗, 并使其直 径较大的一端进一步***沙土中 20〜40 cm (图 4)。
所述的在荒漠和半荒漠环境中提高梭梭属植物直播苗和移栽苗成活率的方法还包括 维护管理步骤,具体方法为:播种或移栽的梭梭属植物幼苗需使用圆柱形管件或中空子弹 型管件进行连续 3〜5年的防护, 期间对死亡的幼苗在春季及时补苗或补种, 对由于风吹 日晒而破损的圆柱形管件或中空子弹型管件进行适当的清理和更换,对因风沙作用而歪斜 和掩埋的圆柱形管件或中空子弹型管件要重新扶正和清除沙土。
所述的圆柱形管件或中空子弹型管件的材质优选 PVC、 石棉瓦、 陶瓷、 珍珠岩, 进 一步优选 PVC。 所述的圆柱形 PVC管件可由目前房屋建筑中普遍使用的直径为 7.5或 11 cm的 PVC输水管截断而形成的两端开口的短管。 所述的中空子弹型 PVC管件由圆柱形 PVC管件的一端经热熔压縮处理后制成, 也可采用其他方法制作。 由于 PVC管件的上端 开口较小, 可阻挡大型食草动物的直接啃食; 同时由于 PVC管件的管壁光滑, 可在一定 程度上减少小型动物 (食草昆虫)爬入管件内啃食梭梭苗。
实施本发明方法需满足以下生境条件: 实施地区生态环境较为严酷, 夏季 6〜8月间 极端高温( 40°C)和干旱天气时有发生, 超过 55 °C地表层 (1〜2 cm)高温频繁发生; 但 该地区春夏季 (4〜8月)浅层沙土 (60 cm以下)悬湿水含量相对丰富, 可保证梭梭属植物幼 苗正常生长所需水量。
本发明所述的在荒漠和半荒漠环境中提高梭梭属植物直播苗和移栽苗成活率的方法 在荒地、 黄土高坡等地表层温度高的地方植树造林中的应用。
引起荒漠沙土地表层温度极端升高的主要原因是晴天和高温 (气温 30°C)情况下的 强光直射,所以只要对直接照射到地表的强光进行一定程度的遮阴, 即可防止地表层温度 极端升高。 在梭梭属植物茎基部套一个 PVC管件即可对幼苗进行防护, 可达到防止地表 层温度极端升高并使植物本身免受地表层高温胁迫的效果。 由于 PVC管件的隔热效果较 差, 当管件内外的地表保持同一水平面时, 管件外的地表高温能够逐渐传入管件内, 也可 造成对梭梭苗的伤害。 为解决这一问题, 在梭梭苗移栽完成后, 再用 PVC管件套住梭梭 苗并下埋 5 cm后, 可在管件***堆土 10 cm以上, 使管件外的地表远高于管件内的地表 平面, 这样即可隔绝管件内外的热传递, 又可加固管件保持固定位置。
有益效果:
本发明依据荒漠和半荒漠环境中地表层高温对梭梭属植物直播苗和移栽苗成活率以 及对幼树和成年树 "夏休眠"现象影响的最新研究成果, 展开在荒漠和半荒漠极端逆境条 件下显著提高梭梭属植物直播苗和移栽苗成活率, 以及防止幼苗、幼树和成年树发生"夏 休眠"现象方法的确立,建立了在荒漠和半荒漠严酷生境中大规模营建梭梭属植物林的关 键技术方法。 其具有下述优点:
(1) 本发明利用圆柱形管件或中空子弹型管件,尤其是 PVC圆柱形管件或 PVC中空 子弹型管件对荒漠和半荒漠环境中的梭梭属植物直播苗和移栽苗进行防护,由于 PVC管件 的防护作用, 可在管件内形成一个小环境, 这一小环境具有保湿和防风的作用。根据我们 多年积累的经验表明, 沙漠环境中的春季是梭梭种子萌发和生长的关键时期, 而地表 0〜 10 cm浅层沙土的含水量对梭梭种子萌发和生长具有决定性作用, 但春季的沙漠环境浅层 沙土的水分散失非常快, 这部分水分主要是被干燥的地表劲风带走。 PVC管件在春季可阻 挡地表劲风吹入管件内,不但能防止水分的过快散失,使管件内的小环境地表保持一定的 墒情,十分有利于梭梭直播苗的萌发和生长,还能防止梭梭苗因劲风吹拂所致倒伏或折断。
(2) 本发明所使用的圆柱形管件或中空子弹型管件具有一定的防止风沙掩埋梭梭属 植物直播苗的作用,在风沙较小或较大的沙漠和沙丘上,幼苗在圆柱形管件或中空子弹型 管件防护下可显著降低被风沙掩埋的几率;此外,幼苗在圆柱形管件或中空子弹型管件的 防护下,可有效阻止荒漠动物的啃食; 由于圆柱形管件或中空子弹型管件可阻挡地表劲风 的吹入而带走水分, 加之管件内的地表温度相对较低, 水分蒸发散失较慢, 为幼苗的前期 生长提供适宜的小环境。 这些特点都可进一步提高幼苗成活率。
(3) 据我们多年的实地调查和研究表明地表层高温 55 °C )是导致梭梭属植物产 生 "夏休眠"现象的根本原因。而使用的 PVC管件可以防止阳光对茎基部及其周围土壤的 直接照射, 从而有效地降低茎基部及其周围地表层温度, 达到有效防止梭梭属植物幼苗、 幼树和成年树产生"夏休眠"现象, 从而可显著增加梭梭属植物年有效生长发育期, 增加 年生长量, 加快个体生长发育, 促进荒漠、 半荒漠梭梭属植物生态林的快速恢复和重建, 具有很好的应用前景。
(4) 本发明技术可进一步延伸使用的范围,只要是因为地表层温度的原因造成某一具 有一定生态和经济价值的植物不能在某地生存, 都可使用 PVC 管件进行相应的实验和应 用。 此外, 管件的材质可以不限, 既可以是 PVC塑料材质, 也可以是石棉瓦、 珍珠岩、 陶 瓷等其它材质, 只要能满足制作简单, 成本低廉, 坚固耐用的要求即可使用。
(5) 本发明所使用的圆柱形 PVC管件或中空子弹型 PVC管件制作简单,成本低廉,便 于操作, 适合于大面积推广应用。
(6) 本发明与中国发明专利申请 CN101965788A用防护网罩提高梭梭树植物存活率的 方法相比, 具有如下优点: ① PVC管不易被风沙损坏, 具有更好的防止小动物啃食、保湿、 防风沙伤害和掩埋以及降低地表层温度的效果, 防护年限更长, 维护成本更低; ②原材料 充足, 加工制作简便, 便于工业化生产, 成本低, 而且更坚固耐用。 每个成品的 PVC管件 的原材料成本加上加工成本仅为 0. 8〜3. 0元。 ③直播苗和移栽苗成活率更高, 在风沙较 小的荒漠和半荒漠地区, 成活率平均提高 20%以上, 而在风沙大的荒漠和半荒漠地区, 成 活率平均提高 50%以上。
综上所述,本发明方法解决了一直以来在西北荒漠严酷生态环境中梭梭属植物林营建 过程中所遇到的直播苗和移栽苗成活率极低的关键瓶颈问题,为梭梭属植物林的大规模恢 复和营建提供了有利的技术支撑, 具有很好的应用前景。 附图说明

生存于我国西北荒漠和半荒漠地区的梭梭属植物林在防沙固沙、减缓荒漠化和维护生 态安全上具有不可替代的生态利用价值。然而因为荒漠生存环境的极其严酷,梭梭属植物 人工林的恢复和营建及其困难, 主要的瓶颈问题是梭梭属植物直播苗和移栽苗成活率极 低, 一般当年播种的直播苗成活率只有 1%, 移栽的幼树成活率只有 10%。研究表明, 荒漠 和半荒漠环境中的极端地表层高温胁迫是导致梭梭属植物直播苗和移栽苗大量死亡的关 键原因。为此,使用本发明圆柱形管件或中空子弹型管件对梭梭属植物幼苗和幼树进行相 应防护可显著提高直播苗和移栽苗成活率。
圆柱形 PVC管件制作较为简单,只需在市场上购买一定规格的 PVC输水管,用砂轮切 割机按一定的尺寸切割截断即可制成, 制作效率非常高。 中空子弹型 PVC管件由圆柱形 PVC管件的一端经热熔压縮处理后制成, 可自己加工, 也可向 PVC管生产厂家订购。 在 具体确定某一荒漠地区或地块要应用本发明技术之前,首先要对该地的生态环境进行仔细 考察, 充分了解该地区或地块在炎热的夏季是否存在发生几率较高的极端地表层高温
55°C)现象。 如果该荒漠区不存在极端地表高温, 就没有必要使用 PVC管件进行相应的防 护。 此外, 还要了解该地区 60 cm以下沙土层在夏季的 6〜8月间是否存在较丰富的悬湿 水, 如果水分含量较低, 梭梭属植物直播苗和移栽苗的成活率将显著降低。如果对水分情 况不甚了解, 可应用本发明先实验后推广。
使用 PVC 管件播种或移栽梭梭属植物幼苗时要选择适宜的时间, 一般于每年的 11 月至翌年 4月份进行,此时荒漠环境中的沙土含水率较高,幼苗容易成活。实际使用 PVC 管件时,三种管件的使用方法略有不同。直播苗圆柱形 PVC管件(简称直播苗 PVC管件, 下同, 示意图见图 la) 使用时, 将管件的一端***或埋入沙土中, 然后将梭梭或白梭梭 种子撒播于管件的沙土表面并少量 (1〜2 cm厚)覆土, 最后在管件***堆土即完成整个播 种过程。 移栽苗圆柱形 PVC管件 (简称移栽苗 PVC管件, 下同, 示意图见图 lb) 使用 时, 先将梭梭或白梭梭幼苗植入沙土中, 植深 40 cm, 然后将管件从上向下小心套住移栽 苗, 并进一步将管件***或埋入沙土中, 最后在管件***堆土即完成移栽工作。 中空子弹 型 PVC管件(示意图见图 2)使用时,先将梭梭或白梭梭幼苗植入沙土中,植深 40〜60 cm, 然后将管件从大开口端自上而下小心套住移栽苗,并进一步将管件的大开口端(即直径较 大的一端) ***或埋入沙土中 20〜40 cm深, 不需堆土即可完成移栽工作。 PVC管件对 梭梭和白梭梭直播苗和移栽苗的防护需要持续 3〜5年,所以每年需对 PVC管件及其小苗 进行相应的维护管理, 主要包括对死亡的苗木进行补苗, 对破损的和歪斜的 PVC管件进 行更换和扶正等。
