俗话说:“麦扎黄泉谷露糠,豆子耩在地皮上”。意思是小麦要深播,谷子、大豆要浅播。其实这是在水浇条件差,秋种需要抗旱而无力造墒的情况下,不得不采取的措施。通过近年来的考察,证明深播对小麦的生长发育是不利的。为了进一步摸清不同播种深度对小麦出苗,分蘖及产量性状的影响,我们于1976年秋种期间选用泰山1号小麦进行了试验。供试土壤为轻壤土,试验设计为1厘米、3厘米、5厘米、7厘米四个不同深度的处理,重复三次。小区面积一平方米。播前深翻20厘米,亩施土粪16,000斤,过磷酸钙160斤,硫酸铵120斤(其中60斤作基肥,60斤在起身期追施)。各种肥料均按小区数量
As the saying goes: “Mai Zha Huangquan Valley exposed bran, beans 耩 on the ground.” Means that wheat to deep broadcast, millet, soybeans to be shallow. In fact, this is the poor water conditions, autumn species need drought and unable to create moisture situation, had to take measures. Through the inspection in recent years, it has been proved that deep-seeding is unfavorable to the growth and development of wheat. In order to further understand the effects of different sowing depths on the emergence, tillering and yield traits of wheat, we tested the wheat variety Taishan 1 in the autumn of 1976. The test soil for the light loam, the experimental design for the 1 cm, 3 cm, 5 cm, 7 cm four different depths of treatment, repeated three times. Area of one square meter. Sowing 20 cm deep before sowing Shi Mushi 16,000 pounds, 160 kg of superphosphate, 120 kg of ammonium sulfate (of which 60 pounds as a base fertilizer, 60 pounds in the wake of the chase). A variety of fertilizers by the number of cells
