过去我区紫云英种子产量较低,一般亩产仅30厅左右,种子不能自给,年年要向外省调进大量种子,影响紫云英的发展。近年来,各地应用早地种植留种,紫云英种子产量普遍提高40%左右,有的甚至翻一番,亩产高的达140斤,种子自给有余。1976至1978年分别凋出15万斤至45万斤,现将旱地紫云英留种高产栽培经验介绍如下:一、旱地留种好处多(一)紫云英旱地留种可以解决沿海平原与双季水稻争地争季节的矛盾,保证了早稻能适时插秧,有利早,晚双季稻实现高产稳产。
In the past, the production of Asparagus seedlings in our district was relatively low. Generally, the average yield per mu is only about 30 ha. The seeds can not be self-sufficient. Large amounts of seeds are transferred to other provinces every year, which affects the development of the milk vetch. In recent years, the application of early planting in various places throughout the country, Ziyun Ying seed production generally increased about 40%, and some even doubled, up to 140 pounds per mu high yield, self-sufficient seeds. From 1976 to 1978 witnessed 150,000 jin to 450,000 jin respectively. Now, the experience of high yielding cultivation of Astragalus species in dry land is described as follows: I. The advantages of land-keeping in dry land (1) The conflict between the two seasons of rice to fight the season, to ensure timely planting of early rice, favorable early and late double cropping rice to achieve high and stable yield.
