但控释肥提早施用处理(T3)则植株生长势及生理代谢活性增强,有利于产量的提高和品质的改善。
The early-larger CRF treatment ( T3 ) enhanced plant growth and physiological activity , so increased yield and quality improvement .

结果表明:(1)单一速度型控释肥(FP2,FP5和FP9)在养分快速释放期内,养分释放速率基本保持不变,其顺序为FP2FP5FP9;
Results showed that the release rate of the single longevity CRF ( FP_2 , FP_5 and FP_9 ) was stable and the order of release rate was in order of FP_2FP_5FP_9 during the rapid release period .

水稻控释肥N的释放速率在1535℃范围内随温度的提高而提高,温度每提高10℃,N的释放速率提高1.82.0倍。
In water at 15 ? 5 ℃, the rate of nitrogen release from rice controlled fertilizer was increased as temperature increased .
-
在25℃恒温水培条件中,早稻控释肥N的释放率达到80%时的持续时间为50天,晚稻控释肥为70天。
In water of 25 ℃, it takes 50 and 70 days after applying them that 80 % of N was released from early rice controlled release fertilizer and late rice controlled release fertilizer , respectively .
-
因此,Richards函数比Logistic函数能更准确地描述和预测树脂膜对不同控释肥养分释放动力学特性。
It is concluded that Richards equation is better than Logistic one to describe and forecast nutrient release dynamic properties of the multi-longevity CRFs by using ion exchange resin membrane .

结果表明,新型大球包膜控释肥处理淋滤液pH值显著高于未包膜肥料处理,但与不施肥空白处理和其他2种控释肥处理差异不显著。
The results showed that the leachate pH of big spherical coated controlled-release fertilizer was significantly higher than that of the soluble fertilizer , but there was no significant difference with no fertilizer control and the other two kinds of controlled-release fertilizer treatments .
-
尿素与控释肥配施,土壤NH4~+-N、NO3~&N及矿质态氮含量界于二者之间。不同时期内土壤NH4~+-N的来源不同,0~20d内,尿素对土壤NH4~+-N含量贡献最大;
When urea was added with CRFs the contents of ammonium , nitrate and mineral nitrogen in soil were between with urea and CRFs during the whole incubation .
-
控释肥等量养分常规施用处理(T2),其养分释放过晚,不利于生姜的吸收,其氮、磷、钾当季利用效率仅分别为22.02%、16.02%和25.31%。
Due to the nutrient release late , the nitrogen , phosphorus and potassium using efficiency of the regular pattern CRF treatment ( T2 ) were for 22.02 % , 16.02 % and 25.31 % only .
-
每个穴盘施入控释肥量为117g(克)时,由于施肥量过大对波斯菊幼苗的生长产生抑制作用,施入控释肥量为35g(克)时,育苗效果最好。
When controlled-release fertilizer application amount was 117 g , the growth of seedlings was restrained . The optimum amount of fertilizer on calliopsis plug-seedling was 35 g.
