1986年10—12月,我有机会在沈阳市新农种子繁育基地做收种工作。在此期间我进行了玉米种子水分与发芽率关系的试验。试验选取有代表性的10户农民的王米种子(品种均为丹玉13号)为样本,于11月24日和12月2日分两批利用电温箱和发芽皿做发芽试验(两次重复)。采用正规的发芽试验方法及计算方法,用日本进口水分测定仪测定种子含水量,试验结果如表。从表中看出,水分为17.1—20.1％的种子发芽率为94—96％,均达一级种的发芽率标准;水分为20.7—23.3％的发芽率多数在85％以下,不合乎一级和二级种子发芽
From October to December 1986, I had the opportunity to do planting in Shenyang Xinnong Seed Production Base. During this period I conducted a test of corn seed moisture and germination rate. In the experiment, 10 representative peasants Wang Mi seeds (varieties are Dan Yu 13) were selected as samples, and germination tests were conducted in two batches on November 24 and December 2 using electric incubators and sprouts Repeated). The use of formal germination test methods and calculation methods, the moisture content measured by Japan imported moisture meter, the test results are shown in the table. Seen from the table, the germination rate of seeds of 17.1-20.1% is 94-96%, reaching the germination rate of the first grade; the germination rate of 20.7-23.3% is mostly below 85%, which is not suitable for one Sprouting of second and second seeds
