Abstract

Alfalfa (Medicago sativa) is considered to be one of the oldest and most important fodder plants. Its current importance in improving soil fertility by fixing atmospheric nitrogen with the help of bacteria (Rhizobium meliloti), as well as a cover plant by sequestering carbon, its melliferous value and adaptation to different climate and soil conditions, confirm the importance of this plant in the organic farming system. As a result, in this context, the aim of this work is to highlight the cultivation of alfalfa in an organic farming system in the north-eastern area of Romania, in period 2019-2021, with particular reference to the evolution of the organic surfaces, the framework cultivation technology, as well as some variants of efficient utilization of production. Thus, the organic (certified I, II and organic) alfalfa has had an upward evolution in recent years, being cultivated on 14149,84 ha in 2017 and reaching 25612,86 ha in 2019. Also, in organic farm from North-east development region of Romania, the average production of alfalfa for dray hay was 4.8 t/ha and price of selling was 144,63 €/t, respectively, the average seeds production was 0.5 t/ha with 206,62 €/t.

罗马尼亚有机农业系统中重要作物紫花苜蓿的演变

苜蓿(Medicago sativa)被认为是最古老和最重要的饲料植物之一。它目前在细菌(根瘤菌)的帮助下通过固定大气氮来提高土壤肥力方面的重要性，以及通过固碳来作为覆盖植物的重要性，它的芳香价值和对不同气候和土壤条件的适应，证实了这种植物在有机农业系统中的重要性。因此，在此背景下，本工作的目的是强调2019-2021年期间罗马尼亚东北部地区有机农业系统中紫花苜蓿的种植，特别是有机表面的演变，框架栽培技术，以及一些有效利用产量的变体。因此，有机(认证I、II和有机)紫花苜蓿近年来呈上升趋势，2017年种植面积为14149.84公顷，2019年达到25612.86公顷。此外，罗马尼亚东北发展地区的有机农场，干干草苜蓿的平均产量为4.8 t/公顷，销售价格分别为144.63欧元/吨，种子的平均产量为0.5 t/公顷，销售价格为206.62欧元/吨。
