富硒康对春小麦株高及产量的影响

Effect of Fuxikang Fertilizer on Plant Height and Yield of Wheat

研究结果表明,小麦分蘖末期喷施48 mL/m2富硒康增产效果最好,其次是58 mL/m2处理,同对照相比达显著差异,提高产量11%以上;而开花期喷施富硒康不利于产量的提高。同一喷肥水平下,分蘖末期处理产量均高于开花期处理,且达显著水平。在本试验范围内只有分蘖末期喷施较高浓度的富硒康同对照相比可降低株高。分蘖末期喷施富硒康穗粒重与产量呈显著正相关,在开花期喷施富硒康穗粒数与产量呈显著正相关。

In condition of different spray fertilizer level at the same time, 48mL/m^2 was the best that Fuxikang was sprayed to the wheat in late tillering stage, secondly was 58mL/m^2 and the yield added 11% than the comparison, and it reached the salience level（0.05）, and make yield against increase when Fuxikang was sprayed in florescence. When the amount of the fertilizer was same, the yield of the treat late tillering stage was higher than that of florescence and it reached the salience level. Only in this test. higher thickness was spayed in late tillering stage that the plant height was reduced then the contrast. Between weight of seeds of spike and yield were sali ence positive correlation that Fuxikang was sprayed in late tillering stage , and number of seeds of spike and yield were salience positive correlation that in florescence.
