使用良种是农业生产上投资少、见效快、收益大最经济有效的一项增产措施。然而,良种也并非万能,往往因使用方法不同产生不同经济效果。以我县小麦生产为例,同是几个良种,由于使用的侧重不同,有的单位和农户其产量稳步上升,有的则不然,年度间产量升降变幅很大。由此可见,开展农作物合理用种的研究和探讨,是摆在农业科技工作者面前的一个重要课题,也是当前农业生产上急需的、农民群众渴望解决的一个比较突出的问题。尤其随着现代化育种方法的应用,培育出新的优良品种愈来愈多,研究如何使用好品种就更重要了。
The use of fine seeds is a measure of increasing production that is less costly, quicker and yields the most cost-effective in agricultural production. However, seed is not a panacea, often due to the different methods of use have different economic effects. Take the production of wheat in our county as an example, with several improved varieties, the output of some units and farmers has steadily risen due to the different focuses of use. Thus it can be seen that carrying out the research and discussion on the rational use of crops is an important issue facing agricultural scientists and technicians, and is also an urgent problem which is urgently needed in agricultural production and peasants’ desire to solve. Especially with the application of modern breeding methods, more and more new varieties have been cultivated. It is even more important to study how to use good varieties.
