采用良种是一项投资少、见效快、收益大的增产措施。但有些人采用了良种而没得到良好的增产效益。原因是没有与良法配套。良种,是指在作物品种中多种性能表现良好的品种。种子是有生命的,受自然环境的影响,适应性有一定的限度。因此,良种是相对的,不是绝对的。在甲地是良种,移到乙地也可能不是良种。地域不同,要求不同,良种的标准也不同,离开具体条件,很难说是良种。即使是同一地区,同一良种,因地力、栽培管理措施不同,其产量结果也大不相同。如何做到良种配良法呢?①要因地制宜选良种,做到品种对路。了解良种的特性,再对照地力、气候等自然条件选用。②针对良种特性采取与之相适应
The use of seed is a less investment, quick, large yield increase measures. However, some people use good seeds without gaining a good yield increase. The reason is not with good law package. Variety, refers to a variety of varieties in the performance of good varieties. Seeds are alive, affected by the natural environment, there is a certain degree of adaptability. Therefore, the elite is relative, not absolute. In A is a good seed, moved to B may not be a good seed. Different regions, different requirements, different standards of seed, leaving the specific conditions, it is hard to say that is a good seed. Even in the same area, the same species, due to different soil fertility and cultivation management measures, have very different yield results. How to do well with the good method? ① should be selected due to local conditions, to breed the right path. Understand the characteristics of seed, and then control the force, climate and other natural conditions selected. ② adapt to the characteristics of the species to adapt
