以嫁接番茄品种烟粉207为供试材料,研究了基质袋培、基质槽式栽培、土壤栽培3种栽培形式对嫁接番茄生长及果实品质的影响。试验结果表明,基质槽式栽培的嫁接番茄总产量比土壤栽培的增加了25.8%,前期产量增加了150.0%;基质袋培嫁接番茄总产量比土壤栽培减少4.6%,但前期产量增加了214.8%。2种基质栽培处理的嫁接番茄的株高、茎粗、叶片数等生长指标均低于土壤栽培,但果实硬度、VC含量、可溶性固形物含量等指标明显高于土壤栽培,显著提高了番茄的品质;二者光合速率无显著差异,均显著低于基质袋培形式。 相似文献

试验以寒盛番茄(Lycopersicon esculentum Mill.)品种为材料,研究了接种丛枝茵根真茵(Arbuscular Mycorrhizal Frngi,AMF)、摩西球囊霉(Glomus mosseae Nicolson & Gerdemann)对番茄幼苗生长、叶片光合参数、叶片矿质元素含量的影响.结果表明,接种AMF处理明显地增加了番茄幼苗的生长势、叶片叶绿素含量和光合参数,提高了叶片中N、P、K、Ca、Mg、Zn的含量,其中接种AMF处理对番茄幼苗的株高、叶面积、地上部生长量、叶绿素含量、光合速率、Zn含量影响较大.该试验初步表明,接种AMF处理用于番茄育苗是可行的. 相似文献

为探索适合密云地区秋冬季节原味番茄的栽培方式,选取原味番茄“原味1号”为试验材料,比较靠接法和插接法2种不同嫁接方法的应用效果,分析测定了嫁接成活率及工效,生育期、抗逆性、商品性等不同指数。结果表明:原味番茄品种经嫁接后长势旺盛,株高、茎粗、叶片数、根生长量均较自根苗显著增加,产量提高10%以上,且能够保持较好的口感。经综合比较,插接法更为省工,适合在密云地区种植推广。 相似文献

随着保护地番茄栽培面积的不断扩大,土传病害如番茄青枯病、枯萎病等普遍发生,用植保手段难以克服,采用嫁接的方法不但能有效控制土传病害,而且番茄植株生长势强,产量高.2011~2012年我们在钟埭街道大力村蔬菜种植户进行了大棚嫁接番茄试验,试验结果表明:嫁接提高了番茄抗病、抗重茬能力,在连作田块可有效预防番茄青枯病和枯萎病等土传病害的发生;增强植株长势,采收期延长30d左右,提高了单产;由于采用嫁接换根,使植株获得了抗病机能,抗寒性增强,新陈代谢旺盛,增强了养分吸收能力,从而提高了番茄产量;2年平均每667m2产量8120kg,平均667m2产值15600元,嫁接番茄比不嫁接每667m2产量增加2220kg,增产27.3%,每667m2产值增加4250元,增效27.2%;采摘期提早到2月下旬,比不嫁接提前10~15d,增产增效显著.现将项该技术介绍如下. 相似文献

砧木和接穗苗龄对顶插接法西瓜嫁接苗生长发育的影响 总被引:1,自引:0,他引:1
采用二因素完全随机设计,研究不同砧木和接穗苗龄对顶插接法西瓜嫁接苗成活率、嫁接苗形态指标、叶绿素含量及根系活力的影响。结果发现,随着砧木苗龄的增大,嫁接苗的根系活力均呈先增加后降低的趋势,叶片数、接穗干质量、嫁接成活率、茎粗、叶片叶绿素含量的变化各异;随着接穗苗龄的增大,嫁接苗的嫁接成活率、叶片数、茎粗、接穗干质量、叶片叶绿素含量、根系活力均表现为先增高后降低的趋势。采用隶属函数法综合评价西瓜嫁接苗的质量,发现接穗苗龄9~13d、砧木苗龄11~15 d的西瓜嫁接苗隶属函数值较大,是适合西瓜顶插接法的接穗和砧木最佳苗龄时期。 相似文献

在早春持续低温阴雨寡日照的天气下,以甬砧5号嫁接的拿比特西瓜嫁接苗为试验材料,利用LED灯、高压钠灯于心叶刚长出时进行连续25d的补光,以自然光照为对照。结果表明,人工补光能明显促进西瓜嫁接苗的生长,补光17d起,采用LED灯和高压钠灯处理的砧木下胚轴长度和接穗下胚轴长度快速提高,嫁接苗整体株高增长显著,且叶面积增大,砧木和接穗茎粗增粗,嫁接苗生物量积累加快,接穗真叶叶绿素含量提高,叶片光合能力增加,嫁接苗成活率提高,苗期猝倒病等发病率降低。不同光源比较,LED灯的效果优于高压钠灯,且长期运行的投入成本和使用成本也更低,是今后农业领域最有前途的人工补光光源之一。 相似文献

The present study was conducted to determine the phenological changes in leaf nutrient contents in 10-years Vitis labrusca L. grapes grafted on 140Ru, 5BB and 5C rootstocks. In the experiment, changes of leaf macro and micro element contents from bud burst to post harvest period were investigated in the heavy clay soil conditions. Nutrient contents of leaf blades showed varied depending on the phenological stages and rootstocks (P < 0.01). P, K, Mg and Ca levels of leaf blade exhibited significant differences based on rootstocks and phenological periods between blooming and veraison. While Zn level was obtained sufficient on 5BB of grafted grapevines, it was found to be insufficient in grapevines grafted on 140Ru and 5C rootstocks. In general, grapevines were found insufficient for P, K and Mg nutrients. Total chlorophyll contents of leaves were found at high in the blooming period. Although the highest chlorophyll contents were found in the blooming period, it was determined at the lowest through to harvest. In the study, 5BB rootstock was evaluated to be favorable in terms of nutrient uptake. 相似文献

This research was conducted to determine the changes in the seasonal carbohydrates of annual shoots and growth characteristics of 10 years old ‘Trakya ?lkeren’ grape variety. Grapevines are grafted on 5BB and 5C rootstocks and they were grown in heavy clay soil conditions. In the study, changes of sugar, starch and total carbohydrates were determined from bud burst to dormancy. While sugar, starch and total carbohydrates showed significant differences (P < 0.01) there were no differences between rootstocks. Although sugar, starch and total carbohydrates of shoots decreased from bud burst to blooming, they increased thereafter until vegetative growth stopped. Total carbohydrates of annual shoots have been found to accumulate in period from blooming to harvest. Total and mean leaf area, shoot length and diameter, total chlorophyll and chlorophyll a/b ratio showed significantly variation among rootstocks and phenological stages (P < 0.01). Whereas the highest chlorophyll contents were found in the blooming, it was found at the lowest through to harvest. Overall mean and total leaf area, shoot length and shoot diameter, total chlorophyll content and chlorophyll a/b ratio were significantly higher on 5BB grafted vines. In the study, 5BB rootstocks are found suitable in terms of shoot carbohydrate accumulation and growth characteristics for ‘Trakya ?lkeren’ grape variety. 相似文献

以甜菜ST13092、SD13829、25和H10474为材料。通过盆栽水培研究了不同钠钾比作用下对甜菜幼苗的干物质重、叶面积、总叶绿素含量及光合速率的影响。结果表明,当Na+替代K+50%时,耐盐品种甜菜幼苗的干物质量、叶面积、叶绿素含量和光合速率均有所提高;而耐盐弱品种甜菜幼苗的干物质量、叶面积均有所下降,叶绿素含量和光合速率均有所提高。随着钠钾替代率的增加。所有甜菜幼苗的干物质量、叶面积、叶绿素含量和光合速率均有所下降。研究结果表明:钠钾替代对于耐盐品种的效果要明显优于耐盐弱品种,Na+只能部分替代K+,不能完全替代K+的功能。 相似文献
