Improving the Pastures in the Cindrel Basin by Applying Some Environment-Friendly Technologies

摘要

The experiments have been carried out in the Cindrel basin, at an altitude of 1348 m, near the Paltinis resort. The area of the experimental field is 1 ha.We have come up with two experimental fields. We used herbicide on one field, while the other field remained unaltered. Both fields were sowed with different types of species and mixtures. The two fields had 7 experimental variants each, with three repeats each. V7 was fertilized with sheep wastes for 3 nights, the density being that of 1.5 sheep/ m. V2 up to V6 were fertilized with dung in different quantities.Analyzing the green mass yield achieved from the two types of pastures taken into study, we noticed that the yield varied between -0.21 and 0.88 t/ha for the pasture where we had used herbicide, due to the way in which the vegetation came to an end, through spontaneous colonization and out of the seed supply.As far as the other pasture was concerned, the one on which we hadnt used herbicide, the yield varied between -0.40 and 0.60 t/ha.Applying these systems may lead to an evolution of the floristic composition which may be favorable to growing evergreen forage leguminous plants. On the other hand, the cultivated leguminous may bring, through biological fixation, the amount of nitrogen necessary for producing a satisfactory and good quality green mass yield. The system which we have put into practice is non-pollutant and it can be applied in such a way that, besides protecting the prato-ecosystems involved, it can also contribute to the enhancement of the economic efficiency. It can work if the long-term interest is more important than the short-term interest.
