为了满足柑桔生产日益发展对苗木增长的需要,我省各单位几乎每年需从省外调入近万斤枳种。由于枳主要产于山东、苏北、皖北、湖北一带,运输距离远,采种技术要求比较高,稍不留意,常造成种子霉烂或是过分干燥丧失发芽力等不良后果,既造成经济上的损失,又耽误季节。如1966年,我省从江苏泗阳统筹采集枳种一万余斤,就是由于途中转运时间长,导致很大一部分发霉变质的。近两年来,有些单位在枳种处理中,不是将洗净的种子阴干,而是置于太阳光下曝晒,播种后出苗率很低。这是因为曝晒往往会杀伤种子幼胚,或使种皮
In order to meet the growing demand for the growth of citrus seedlings, the units in our province need to transfer nearly ten thousand jinzhi from outside the province every year. Because Trifoliate is mainly produced in Shandong, northern Jiangsu, northern Anhui, northern Hubei area, transport distance, mining technology requires relatively high, a little noticed, often resulting in poor or too dry seed germination and other adverse consequences, both to create economic Loss, but also to delay the season. For example, in 1966, the province collected more than 10,000 jin from the Siyang City, Jiangsu Province. This was due to the long transit time on the way, resulting in a large part of moldy deterioration. The past two years, some units in the treatment of Zhoushi, not to wash the seeds dried, but placed in the sun exposure, seedling emergence rate is very low. This is because exposure often kills the seed immature embryos or makes the seed coat
