缓释型氮肥对棉花和水稻生长发育影响的研究

研究了缓释型氮肥对棉花和水稻生长发育的影响,结果表明:缓释型氮肥与氮肥对棉花和水稻产量和品质没有明显差异;但较对照能够明显提高棉花的产量,铃数、铃重衣分均有增加,株高增加,果枝数增加,但对纤维品质没有大影响;缓释型氮肥与氮肥较对照水稻群体较大,分蘖力强、成穗率高、穗粒数多,产量增产显著;品质有较大的提高。

The Study on Slow Release N Fat to Cotton and Rice Growth Influence

This article has studied the effect of slow nitrogenous fertilizer on the growth of cotton and rice. The result shows no obvious difference of yield and quality by applying slow release nitrogenous fertilizer and normal nitrogenous fertilizer. But comparing with its comparison, the yield, amount of boll and boll weight of cotton has been increased, and plant height , amount of branch were increase as well. For rice, applying slow release nitrogenous fertilizer can improve the tillering ability, earbering tiller rate and the amount of rice ear. The yield and quality has been markedly increased.
