dc.description.abstractUždarame grunte auginamų pomidorų tyrimai atlikti 2009-2013 metais polietilenu dengtame privačiame šiltnamyje (Alytaus mieste). Tyrimui parinkti Enza Zaden firmos pomidorų hibridai: Loreto H, Corleone H, Dimerosa H, Gualdino H ir Buran H. Darbo tikslas – stebėti uždaruose gruntuose auginamų pomidorų tręšiant ekologiškomis trąšomis augimo ir derėjimo eigą bei iškilusias problemas. Gruntas paruoštas maišant lygiomis dalimis neutralizuotas durpes, kompostą bei šiltnamio žemę. Pridėta organinių trąšų Activit, žuvų miltų, kalio sulfato, kalio magnezijos (N168P52K325Ca204) ir mikroelementų (B, Fe, Mn, Zn, Mo) tirpalo. Vienam pomidorui skiriama 20 litrų grunto, o sodinimo tankis – 2 daigai/m2. Auginama ant vieno stiebo 6 kekės. Augimo ir derėjimo metu kartą per savaitę buvo papildomai tręšiama fermentuotų žolių ištrauka. Pomidorai auginami 40 cm. pločio polietileno juostose mulčiuojant šviežiai pjauta gazonine žole. Papildomai taikytos augalų apsaugos priemonės – vario sulfatas ir pieno, muilo bei jodo mišinys. Tyrimo metu buvo stebima ir fiksuojama augalų vystymasis, augimas ir derėjimas bei atsparumas ligoms. Nustatyta, kad subalansuotame grunte, papildomai tręšiant raugintomis žolėmis ir naudojant augalų apsaugos priemones, pomidorai vystėsi ir augo gerai. Derėjimo metu išryškėjo kalcio trūkumas jautresnės veislės Dimerosa vaisiams. Slyviniams Corleone pomidorams kalcio trūkumas nepastebėtas. Maisto medžiagų pakako suformuoti 6 kekes. Vaisiai pasiekė būdingą veislėms vaisių svorįlt
dc.description.abstractThe investigation was carried out in 2009-2013 at the private polyethylene greenhouse in Alytus town. Hybrid tomato breeds of Enza Zaden concern have been selected for the experiment: Loreto H, Corleone H, Dimerosa H, Gualdino H and Buran H. The aim of the investigation was to assess the influence of soil substrate preparation and additional fertilization on the ecologically growing tomatoes in the small greenhouses. The substrate for the experiment was prepared by mixing the equal parts of peat, compost and soil from the greenhouse. Additionally, substrate was supplemented with organic fertilizers (Activit, fish meal, potassium sulfate, potassium magnesia (N168P52K325Ca204) and micronutrients (B, Fe, Mn, Zn, Mo) solution. The 20 liters of the prepared soil substrate was set up for each one tomato growing and the planting density of two plant seedlings to one square meter have been used. Moreover, the fertilization with the fermented herbal solution once per week was applied at the stage of growth and flowering. Tomatoes were grown in the 40 cm wide plastic strips adding up the fresh cut grass mulch. Each of plant stem has molded six bunches. The copper sulphate and milk-soap-iodine mixture have been applied as a plant protection means. Plant development, growth, yield and resistance against the diseases have been periodically monitored and evaluated during the experiment. In general, the data show that tomato grew and developed well in the balanced soil substrate when additional fertilization with fermented herbal solution plant protection means applied. However, the Dimerosa breed has shown sensitiveness to the calcium deficiency during the yielding period. In opposite, the cherry tomatoes breed Corleone didn’t suffer from the calcium deficiency. Thus, due to the sufficient amount of all the necessary nutrients, cherry tomatoes have molded six bunches and their fruits have reached the mass typical for the breeden
