雾培对网纹甜瓜生长和产量及品质的影响 总被引:2,自引:0,他引:2
以基质培和水培为对照,研究了雾培对网纹甜瓜植株生长、产量和品质的影响.结果表明:雾培网纹甜瓜的株高、茎粗、叶片数、根长、根体积、根系活力和根干物质积累均高于水培和基质培,说明雾培能促进网纹甜瓜植株生长,使其根系发达,长势旺盛.雾培网纹甜瓜单瓜重极显著高于水培和基质培;果实可溶性固形物和维生素C含量与水培和基质培差异不显著;雾培可溶性总糖含量显著低于基质培;有机酸含量显著高于水培,但与基质培差异不显著;蛋白质含量显著高于基质培,说明雾培在显著提高网纹甜瓜产量的同时果实品质有所下降. 相似文献

樱桃番茄水培肥料配方试验 总被引:2,自引:0,他引:2
采用6种肥料配方进行了2年共3茬在樱桃番茄水培试验,结果表明,5号配方处理的樱桃番茄表现茎粗,开展度大,总节数多,植株生长势强,产量高,品质好,较适宜作樱桃番茄水培专用肥。对水培与土培樱档番茄果实NO2的含量进行分析比较,结果5个水培配方处理果实的NO2含量低于土培,初步认为水培并不会合蔬菜产品NO2的含量升高。 相似文献

Oxygen deficiency has an immediate effect on both water and nutrient uptake, the yield of the whole plant under different soilless culture is affected. The oxygen level required for the respiration of the root system then becomes a limiting factor as much in soil culture as in soilless culture. The total area of soilless crops in SE Spain today is estimated to be about 5000 ha. The objective of this experiment was to study the effect of potassium peroxide as an oxygen generator on vegetable crops growing in commercial substrates and to determinate the supply fraction for its use. Bioassay was used to determinate the fraction of potassium peroxide needed. Three greenhouse experiments were conducted in soilless culture with perlite and rockwool. Sweet pepper, melon and cucumber crop were supplied with potassium peroxide through fertigation to increase the oxygen content for one day per week. There were treatments: one with (T1) and the other without potassium peroxide (T0) in the nutrient solution. Fertigation parameters, yield and its quality were measured. Bioassay suggested that one gram per litre is the best fraction to use in soilless culture. Yield of sweet pepper was about 20% higher for T1 than T0 and 15% for melon; there was no significant difference in cucumber plants. 相似文献

无土栽培基质中的微生物及其对作物生长发育的影响 总被引:10,自引:0,他引:10
介绍了无土栽培基质中微生物的种类、数量, 微环境对微生物生长繁殖的影响, 微生物对无土栽培作物生长发育的影响等。基质中微生物种类和数量因基质类型不同而存在显著差异, 而且其种类和活性极易受基质环境因子的影响, 种群主要以细菌为主, 其次是真菌、放线菌、霉菌等, 它们能够参与基质中的营养转化, 提高植物抗逆性, 但在基质中也引起一些真菌病害和少量的细菌病害。本文还提出了基质微生物研究的方向和存在的问题, 并就基质微生物研究利用的前景进行了展望。 相似文献

Yield and quality of wild strawberry (Fragaria vesca L.) cultivars ‘Regina delle Valli’ and ‘Alpine’ cultivated in soil, as the traditional production system, and in soilless (both in open air and protected environments), as an innovative and sustainable production system, were investigated in a marginal and inner area of the Pistoiese Apennine Mountains during two production seasons. An earlier marketable production was obtained in soilless culture, but total marketable yield was higher from plants grown in a traditional open-field environment. Fruits obtained from the protected soilless system were larger, but developed some mildew, had some visual defects, and revealed a reduced skin chroma index, flesh firmness, and total soluble solids content compared to fruits harvested from plants grown under direct sunlight, while no significant differences were observed in total titratable acidity and pH between growing systems. ‘Alpine’ was more suited to soilless protected cultivation, with a much higher yield compared to ‘Regina delle Valli’. Physicochemical properties of berries were not affected by the cultivar, but fruit quality changed with plant age and seasonal crop cycle. ‘Alpine’ fruits gained a greater sensorial preference, both in traditional soil and soilless culture. 相似文献
