摘要

采用盆栽试验研究了缓释复合肥对强酸性土、酸性土、中性土上红三叶产量和品质的效应。结果表明

与等养分普通复合肥相比

不同土壤施用缓释复合肥可显著提高红三叶产量

增产率以强酸性土（55.8%）〉中性土（39.9%）〉酸性土（7.4%）;不同缓释复合肥在不同土壤上的肥效有差异

强酸性土和酸性土上施用低磷钾的缓释复合肥产量高

中性土则以施高磷钾缓释复合肥者产量高。缓释复合肥能改善3种土壤第一茬、第二茬红三叶饲用品质和矿质品质

其中粗蛋白提高4.0%-23.1%

粗脂肪提高2.5%-38.6%

粗灰分提高1.4%-23.6%

粗纤维降低2.5%-23.3%

磷提高4.9%-18.6%

钙提高1.8%-13.7%。红三叶异黄酮含量受土壤影响较大

强酸性土和酸性土上缓释复合肥处理的异黄酮含量低于等养分普通复合肥

而中性土施用缓释复合肥提高了红三叶异黄酮含量。

Abstract

A pot experiment was carried out to study the effect of slow-release fertilizers(SRF) on yield and quality of Trifolium pretense in strong acidic soil

acidic soil and neutral soil.As comparison to common compound fertilization(CCF)

the results indicated that the yield of Trifolium pretense was increased significantly for the application of SRF in different soils

and in terms of the increase degree

the sequence of the soil was strong acidic soil(55.8%)> neutral soil(39.9%)> acidic soil(7.4%).The yield was differ from application of different SRF in different soil.The best yield was appeared for the application of SRF2 in strong acidic soil and acidic soil

while in neutral soil the highest yield was obtained for the application of SRF2.The forge nutritive quality and mineral quality was enhanced for the application of SRF in the first and second batch of Trifolium pretense.The crude protein(CP) was increased from 4.0%~23.1%

the ether extract(EE) was increased from 2.5%~38.6%

the crude ash(CA) was enhanced from 1.4%~23.6%

the acid detergent fiber(ADF) was decreased from 2.5%~23.3%

the element phosphorus was increased from 4.9%~18.6%

and calcium was increased from 1.8%~13.7%.The content of isoflavonoids in Trifolium pretense was strongly affected by different soils

in strong acidic soil and acidic soil the content of isoflavonoids was lower in treatments SRF than in treatment CCF

while in neutral soil the content of isoflavonoids in Trifolium pretense were all enhanced in different treatments.
