农产品品质通常包括营养、食味、加工和外观等方面。品质的标准主要决定于植物被人类利用的目的,不同的经济目的,对品质的要求就有不同的标准。影响品质的因素很多,归纳起来,是两方面:一是遗传品质,由作物种质基因所决定,栽培措施几乎不可能动摇作物的遗传品质,要提高作物品质,育种是最重要的途径;二是农艺品质,它是栽培措施和环境相互作用的产物,其中又以气候和施肥最重要。试验发现,同一品种在不同地点和年份,其蛋白质含量变幅为8.9～15.4%,差异达到显著标准。说明外界条件可以对品质产生显著影响。提高作物的品质,需要采取持续的、综合性的
The quality of produce usually includes nutrition, taste, processing and appearance. The standard of quality mainly depends on the purpose that plants are used by mankind. Different economic purposes have different standards on the quality requirements. There are many factors that affect quality. To sum up, there are two aspects: First, genetic quality is determined by crop germplasm genes. Cultivation measures are almost impossible to shake the genetic quality of crops. To improve crop quality, breeding is the most important way; Is agronomic quality, a product of the interaction between cultivation practices and the environment, of which climate and fertilization are most important. The test found that the same variety in different locations and years, the protein content range of 8.9 to 15.4%, the difference reached a significant standard. Explain the external conditions can have a significant impact on the quality. To improve the quality of crops needs to be sustainable and comprehensive
