温室秋季栽培番茄,要想夺取高产,关键在于调节好番茄的生长与结果的平衡关系。定西县园艺站对温室秋番茄采用连续摘心换头整枝方式,比传统的单秆或双秆整枝方式增产21.7％～32.5％,平均单株坐果率提高15.8％,亩产达8000公斤以上,增加收入1200元。 相似文献

传统的番茄整枝方式为单杆整枝或双杆整枝,导致番茄生长后期植株长势衰减,果实发育不良。为此,我们在1995～1996年进行了日光温室番茄整枝方式的试验研究,试验结果认为两穗果或三穗果连续摘心换头法,其产量、产值均优于前两种整枝方式。 ① 两穗果连续摘心换头法。即第一花序坐果,第二花序开花时,在第二花序上留2～3片 相似文献

于苗期采用灌根处理的方法,研究了碧护、生根粉、超级矮丰王、金云大-120、复硝酚钠、甲壳素对秋季番茄幼苗生理指标、植株营养生长以及产量的影响。结果表明,生根粉处理后番茄秧苗质量显著增加;碧护、金云大-120、复硝酚钠、甲壳素处理,均不同程度地增加了番茄幼苗的株高、茎粗、叶面积、根冠比、G值、壮苗指数及叶绿素含量。定植后,各生长调节剂处理均可促使植株生长势增强,增加现蕾数;生根粉处理显著增加番茄前期产量、平均单果质量及总产量。因此,番茄越冬茬栽培中,为培育壮苗,于幼苗1叶期施用生根粉100倍液效果最佳。 相似文献

以粗砂、蛭石、菇渣、树叶、锯末为基质材料,不同材料按体积比复配后形成10种复混基质,以粗砂基质为对照,进行"欧曼"品种番茄栽培试验。采用相同尺寸栽培槽填充基质、无土栽培水肥管理及田间整枝管理措施,研究了不同配比基质理化性质、根区温度与根区湿度,及其对番茄果实品质及产量的影响。结果表明:复混处理后基质的容重较CK显著降低,孔隙度较CK显著升高;复混基质能改善根区的温湿环境,不同处理平均温度较CK提高了0.35~1.24℃,平均湿度较CK提高1.86%~13.32%;对比果实产量和品质发现T6与T8处理总体表现最好,果实硬度、单果质量、单株产量、单株结果数、增产率均优于其它处理,维生素C、可溶性蛋白质、有机酸含量也均处于较好水平,综合比较发现T6处理(粗砂∶蛭石∶菇渣∶树叶∶锯末=2.5∶2.5∶1∶2∶2)和T8处理(粗砂∶蛭石∶菇渣∶树叶∶锯末=2.5∶2.5∶1∶1∶3)能为番茄生长提供良好生长环境,并能提高番茄的产量及品质。 相似文献

以4个不同番茄砧木品种与夏日阳光樱桃番茄进行嫁接,以夏日阳光自根苗为对照(CK),研究了不同砧木嫁接对樱桃番茄的生长发育、抗病性、抗旱性、品质及产量的影响。试验结果表明,4种砧木嫁接均能显著降低青枯病发病率,其生长势、产量均显著优于自根苗,且品质和口感与自根苗无明显差异,其中,以哥俩好的成活率最高,为95.8%,第一雌花节位最低,采收期最长,青枯病发生率最低,生长势最强,坐果率最高,单果质量最大,糖酸比最大,达7.301,产量最高,达4 858.0 kg/667 m~2,综合表现优异,适宜作为樱桃番茄夏日阳光的嫁接砧木进行推广。 相似文献

不同光质对番茄幼苗生长和生理特性的影响 总被引：71，自引：5，他引：71
就不同光质(蓝光、绿光、黄光、红光及白光) 对番茄幼苗生长和生理特性的影响做了探究。结果表明, 红光处理的幼苗干物质积累多, 叶面积扩展快, 叶绿素含量、光合速率、可溶性糖及总糖含量均最高, 叶绿素a /b比值及总氮含量最低。蓝光处理幼苗的茎粗、叶面积、根系活力、光合速率均显著高于对照(白光) 。壮苗指数以蓝光或红光处理的较好, 说明在苗期照射红光或蓝光可促进番茄幼苗的生长, 有利于培育壮苗。蓝光处理幼苗花期提早, 产量显著提高。 相似文献

SummaryThe combined effects of electrical conductivity (an EC of 2.5 dS m–1 or 8 dS m–1 in the root zone) and fruit pruning (three or six fruit per truss) on tomato fruit quality were studied in a greenhouse experiment, planted in January 2005. Taste-related attributes [dry matter content (DM), total soluble solids content (SSC), titratable acidity (TA), glucose, fructose and citric acid content] and health-promoting attributes (lycopene, βcarotene, vitamin C, and total anti-oxidant activity) of tomato fruits harvested on the vine from the fifth or tenth truss positions were determined. The quality of tomato fruits was improved by high EC. A high EC in the root zone increased the DM content, total SSC, TA, as well as glucose, fructose and citric acid contents. A significantly higher lycopene and βcarotene content was also observed [on a fresh weight (FW) and dry weight (DW) basis] with a high EC in the root zone. The accumulation of different compounds that determine tomato fruit quality differed between the fifth and tenth truss. In particular, the lycopene content was reduced, whereas the βcarotene content was increased in the tenth truss with respect to the fifth truss, most likely because of higher temperatures during ripening of the tenth truss. Fruit pruning increased fruit FW by 42% and positively influenced the DM content and total anti-oxidant activity, while a negative effect was observed on lycopene and citric acid contents (on a FW and DW basis). EC and fruit pruning both had a strong effect on fruit size; however, EC had a much stronger impact on taste and health-related fruit quality attributes. A small interaction between EC and fruit pruning was found for marketable yield, fructose and glucose content, fruit firmness, and P and Ca concentrations in fruits. 相似文献

Effect of pruning intensity on peach yield and fruit quality 总被引：1，自引：0，他引：1
Light, medium and heavy pruning treatments were used with one unpruned as check (control) in Flordasun, Flordaking and Saharanpur Prabhat peaches. Fruit yield decreased with the increase in severity of pruning in Flordaking and Saharanpur Prabhat peaches, whereas, medium pruning treatment gave highest yield in Flordasun peach. Pulp weight, stone weight, pulp-stone ratio, ascorbic acid, sugar acid ratio and moisture content were not affected by pruning levels. However, fruit weight, size, TSS, sugar and acid content were significantly increased by pruning in Flordasun peach. Almost all the physico-chemical characters were significantly affected by pruning in Flordaking and Saharanpur Prabhat peaches, in which medium and heavy pruning treatments performed better, respectively. 相似文献
