Description
  • V podmínkách Hrubého Jeseníku jsme se zabývali energetickou analýzou různých způsobů využívání TTP v letech 2003 - 2005. V pokusu byly uplatněny následující úrovně využití: I1= (1. seč do 15. 5., za rok celkem 4 seče v intervalu 45 dní), I2= (1. seč do 31. 5., za rok celkem 3 seče v intervalu 60 dní), I3= (1. seč do 15. 6., za rok celkem 2 seče v intervalu 90 dní) a I4= (1. seč od 15. 6. do 30. 6., celkem 1 – 2 seče za rok, 2. seč za 90 dní) a čtyři úrovně hnojení TTP: F0= bez hnojení, FPK= P30K60N0, FPKN90= P30K60+N90 a FPKN180 = P30K60+N180. Vypočítali jsme hodnoty jednotlivých vstupů dodatkové energie. Vstupy energie se pohybovali v rozpětí od 2,17 GJ.ha-1 do 22,70 GJ.ha-1. Největší částí energetických vkladů byla hnojiva, která se na nich při intenzivním hnojení podílela až do výše 84,93 %. Z hlediska energetického zisku a náročnosti na vstupy energie se jeví jako nejvhodnější využívání TTP dvěma sečemi za rok. Z hlediska kvality píce v kombinaci s využitím neobnovitelných zdrojů energie můžeme p (cs)
  • In 2003-2005 in the Hrubý Jeseník conditions we were engaged in the energy analysis of the different types of permanent grassland utilization. The levels of intensity of utilisation were following: I1= (1st cut until May 15th, 4 cuts per year – cuts at 45-day interval), I2= (1st cut between 16th and 31st May, 3 cuts per year at 60-day interval), I3= (1st cut between 1st and 15th June, 2 cuts per year at 90-day interval) and I4= (1st cut between 16th and 30th June, 1 or 2 cuts per year, second cut after 90 days) and four levels of fertilizer application: F0= no fertilisation, FPK= P30K60N0, FPKN90= P30K60+N90 and FPKN180 = P30K60+N180. We have counted the values of the particular inputs of the additional energy. The energy inputs data moved from 2,17 GJ.ha-1 to 22,70 GJ.ha-1. The biggest share in energy inputs had fertilizers. It was 84.93% by nitrogen fertilization. From the viewpoint of energy benefit and intensiveness on energy inputs it appears the most available utilization of permanent grasslan
