小麦和其他农作物一样,生长时需要阳光。但是我国南方在小麦生长季节内多阴天,为了明确弱光对小麦生长的影响,对小麦与弱光的关系有一个系统的认识,我们设计了近似于南方阴天光照强度的小麦分期遮光试验。小麦幼穗伸长至二棱期、二棱至拔节期、拔节至孕穗期、孕穗至开花期、开花至开花后10天、开花后10天至成熟期,分别称为第1、2、3、4、5、6期遮光,简称遮光1、2、3、4、5、6;遮光1～2、3～4、5～6分别属于小麦生长的前(拔节以前)、中(拔节至抽穗开花)、后(开花至成熟)期。研究内容包括:①小麦前、中、后期对弱光的反应,受影响最大的器
Like other crops, wheat requires sunlight when it grows. However, in the southern part of our country, there are many cloudy days in the wheat growing season. In order to clarify the effect of low light on the growth of wheat, we have a systematic understanding of the relationship between wheat and low light. We designed a wheat staging test that is similar to the light intensity of cloudy southern China . The young ears of wheat are elongated to two-ridged, two-ridge-to-jointing, jointing to booting, booting to flowering, flowering to flowering to 10 days, 10 days after flowering to maturity, 4, 5, 6 shading, referred to as shading 1,2,3,4,5,6; shading 1 ~ 2,3 ~ 4,5 ~ 6 belong to the wheat before growth (before jointing), medium Heading flowering), after (flowering to maturity) period. The research contents include: ① Wheat before, during and after the response to weak light, the most affected by the device
