| 摘 要： | 本试验旨在探求冬小麦喷施稀土的最佳生育期、浓度和次数的增产效果。研究结果表明，适量的稀土能促进小麦生长发育、增加商有效穗、穗粒数和千粒重。不同生育期喷施稀土的效果是：拔节期＞扬花初期＞冬前分蘖期；喷施不同浓度稀土的增产效果是０．１％＞０．１５％＞０．０５％（每公顷喷施７５０ｋｇ“常乐益植素”液）；喷施稀土次数的增产效果是３次＞２次＞１次。试验结果表明，在中肥力有水灌条件下，在拔节期喷施０１％稀土溶液７５０ｋｇ液／ｈｍ２，增产１５％左右。

| Abstract: | The study deals with the spraying application benefit of RE with different concentration times and in different growing period of wheat. Suitable amount of RE application canstimulate the growth of wheat, increase effective ear numbers, grains per ear and1000-grains weight. The results of spraying application of RE in different growth periodarea jointing period > flowering period> tillering period (before winter), the results of spraying aPPlication of RE with different concentration are: 0. 1 % >0. 15% >0.05%(ChangleYizhisu, 750kg liguid / hm2), the results of spraying application of times of increasing yieldare: 3 times> 2 times>1 time. The results showed that mdium-fertile soil with irrigationcondition, the yields of winter wheat increase 15% approximately, when 750 kg liguid of0. 1% RE were spraying application per hm2. |
