我省秋播豆科绿肥品种少,对农业生产不相适应。五十年代曾引进过不同品系的红三叶、白三叶、杂三叶和绛三叶,并初步得出各品种和品系在我省的适应性能。1978年秋,引进地中海三叶草(Trifojium incamafumj)在果园间作与多点试种,由于没有接种根瘤菌,生产性能表现差。1979年秋,再次引进地中海三叶草,接种本族根瘤菌后,分别在连作晚稻稻底撒播和秋耕休间田作畦条播,其生育期表现,与双季连作稻或一季稻接茬,均相适应。其生产性能,初步反应也相当良好。去秋至今春,全省秋旱、冬冻与春涝,持续时间长,变换又急骤,大面积紫云英生产,普遍受到不同程度损害,而地中海三叶草在相同环境下,仍得到比较高的产量。
Autumn planted in our province less legumes green manure, does not adapt to agricultural production. In the 1950s, red clover, white clover, miscellaneous clover and dark clover of different strains were introduced, and the adaptability of all varieties and strains in our province was initially obtained. The autumn of 1978, the introduction of the Mediterranean clover (Trifojium incamafumj) in the orchard intercropping and multi-point test, due to the absence of inoculation rhizobia, poor performance performance. In the autumn of 1979, once again introduced the Mediterranean clover, inoculated with native Rhizobia, respectively, in the late rice and sowing intermittent interspaces for sowing sowing, its growth period performance, and double cropping continuous cropping rice or a crop of rice, are compatible . Its production performance, initial response is quite good. The fall to the present spring, the province autumn drought, winter freezing and spring floods, long duration, transformation and rapid, large area purple millet production, generally subject to varying degrees of damage, while the Mediterranean clover in the same environment, still get higher Yield.
