培育水稻大穗,可探索单穗生产潛力和通过定向培育,改变提高水稻种性以至育成新的品种。 1960年我区各級农业科学研究机构,在培育水稻大穗方面获得了显著的成績。如黄岩县路桥良种繁育埸,培育出1,042粒的早稻大穗,溫州专区农业科学研究所和一些县农科所也培育出了許多800～900粒以上的大穗,創造了早稻大穗新紀录。目前出現的千粒以上的晚稻大穗,已有溫州专区农科所的1131粒(見图1),溫州农学院和龙泉县农业科学研究所的1070粒,临海县和溫州市农业科学研究所的1200多粒等等。根据各地經驗,培育水稻大穗要注意选用良种、合理施肥、去蘖等技术。选作培育大穗的品种,应具备穗大、粒多的优良特性。而尤其用新育成的大穗品种来培育大穗,比采用老品种容易取得成績,因为新育品种的遺传性还不很稳定,容易接受境环条件的影响。
Breeding large ears of rice, we can explore the potential of single panicle production and by directional cultivation, change to improve the rice species as well as breeding new varieties. In 1960, the agricultural scientific research institutes at all levels in our region have made remarkable achievements in cultivating the big panicles of rice. Such as Huangyan County, Luqiao breeding breeds, cultivating a large panicle of 1,042 early rice, Wenzhou Prefecture Institute of Agricultural Sciences and some county agricultural institute also breed a large number of more than 800 to 900 large spike, creating early rice big spike record. At present there are more than one thousand grains of late rice big spike, there have been 1131 grains (see Figure 1) of Wenzhou Academy of Agricultural Sciences, Wenzhou Agricultural College and Longquan County Institute of Agricultural Sciences 1070, Linhai County and Wenzhou Institute of Agricultural Sciences More than 1200 tablets and so on. According to local experience, to cultivate a large spike in rice should pay attention to the selection of seeds, fertilizers, tillers and other techniques. Selected as a cultivating big ear varieties, should have spike, grain and more excellent features. In particular, it is easy to cultivate large ears with newly cultivated large ears, which is easier to obtain than with old ones because the heredity of the newer breeds is not yet stable and can easily be influenced by environmental conditions.
