Influence of alfalfa seed belts on yield component and seed yield in mainland China - A review

摘要

Alfalfa is widely cultivated and the seed yield differs in different regions due to the climate environment and so on in China. In order to obtain higher yield, alfalfa seed production must choose the most suitable area. Therefore, according to the geographical and climatic conditions, the alfalfa seed production area can be divided into four belts: Hexi Corridor belt, Hetao Plainbelt, the northern slope of the Tianshan Mountains belt and the Hotanbelt in mainland China. Under different cultivation measures, the seed yield of four alfalfa seed production zones, varied in the range of 360-1833 kg/hm(2), 234.96-1560. 1kg/hm(2), 179.10-1197.33 kg/hm(2), 225-300 kg/hm(2), respectively. These different cultivation measures can provide theoretical guidance for alfalfa seed production in different production zones.
