一、种子的扦样种子的扦样关系到整批种子的代表性,是减少室内检验误差的关键。1.混合样品的扦样现在种子的包装一般为麻袋包装,充分混合后的一批种子袋袋扦样,可以按规定最少数量从麻袋一角成斜角45°扦取,原始样品混合均匀后即可进行其它方面的检验。2.分户包装种子扦样分户包装种子在田检阶段可划分为同一检验区。但在室内检验中不应混合样品检验,而应分户进行室内检验,特别是发芽率检验。这是因为个别农户在收获后的措施、条件不一样,可能产生炕芽的可能。混合样品中看不出这种情况。二、种子室内检验种子室内(播种品质)检验,主要指净度、发芽率、水份、病虫率等的检验,下面主要谈净度和发芽率的检验。
First, the seeds of the sample seed sampling sticks related to the representative of the whole batch of seeds is to reduce the key laboratory error. 1. Mixed samples of the sample now seed packaging generally sacks, a group of seeds after a good mix of bags sacks sample, according to the provisions of the minimum number of slanted from the corner of the sack 45 ° skewer take, the original sample after mixing Other aspects of the test can be carried out. 2. Separation of seed packaging seed samples Separation of seed in the field inspection stage can be divided into the same inspection area. However, in the laboratory test should not be mixed sample test, but should be household test indoors, especially germination rate test. This is because individual farmers after harvest measures, conditions are not the same, may produce kang bud may. This can not be seen in the mixed samples. Second, the seed indoor inspection Seed indoor (sowing quality) inspection, mainly refers to the clarity, germination rate, moisture, pest rate and other tests, the following mainly about clarity and germination rate test.
