在小麦拔节期进行了喷施稀土试验。结果表明:喷施稀土能显著增加小麦穗粒数和产量,对千粒重影响则不明显;小麦产量与喷施稀土浓度之间呈二次曲线相关,当稀土浓度为00416%时,理论上小麦可获最高产量2665kg/667m2。
Rare earths were sprayed at wheat jointing stage. The results showed that sprinkling rare earth could significantly increase the number of grains per spike and the yield of wheat, but had no significant effect on 1000-grain weight. The yield of wheat was quadratic curve correlated with the concentration of sprinkling rare earth. When the concentration of rare earth was 00416% The highest yield of wheat is 266.5 kg / 667 m2.
