旱作燕麦平衡施肥技术配套试验

针对燕麦旱作,进行了以有机肥为主体的农肥、氮肥和磷肥配合施用的平衡施肥技术研究,结果表明,施有机肥比不施有机肥燕麦孕穗、抽穗、扬花等生育进度要快一些,株高、穗长、小穗数、穗粒数、穗粒质量、千粒质量等经济性状均有明显的增加趋势。在此基础上配合施用氮磷肥,其生育进度及穗部经济性状增长趋势更明显。与农肥、化肥都不施的处理为对照进行综合比较得出:只施农肥可平均增产8.9%,公顷施15 000 kg和30 000 kg增产效果无明显差异;只配合施用化肥平均增产8.6%,N120P90处理与N60 P45处理2个水平之间差异不明显;农肥、氮肥和磷肥三者配合施用,互作效应明显,可平均增产27.6%;每公顷施用15 000 kg农肥、60 kg纯N、45 kg纯P2O5的处理增产效果最佳,增产可达29.6%。

Experiment of Balanced Fertilization Technology System in Dry Farming Oat

Study on balanced fertilization technology on base farmyard manure, nitrogen and phosphoric fertilizer in oat was conducted. The results showed oat had earlier booting, ear sprouting and flowering, and improved plant height, ear length, spikelet number, seed number per ear, quality of ear seed and thousand seed quality. When phosphoric manure was combined with the a bore mentioned fertilization, oat growth and ear features improved even more remarkably. Compared with the treatment with neither farmyard manure nor fertilizer, the results showed the following： Only application of farmyard manure had a mean yield improvement of 8.9%, and application of 15 000 kg and 30 000 kg showed no significant difference; Only application of fertilizer had a mean yield improvement of 8.6%, and two treatments of N120P90 and N6o 1745 showed no significant difference; Cooperation of farmyard manure, N and P elements showed significant joining action and got a yield improvement of 27.6%; Treatment of 15 000 kg farmyard manure, 60 kg pure N element and 45 kg pure P205 had the best result with a yield improvement as high as 29.6%.
