茶树专用控释肥在幼龄茶园的肥效研究
Efficiency of Special Controlled- release Fertilizer on Young Tea Garden
摘要
Abstract
The Kingenta special controlled- release fertilizers (CRF1 、CRF2) and the common fertilizer (CCF) were applied in 2 - year - old tea garden. The pure nitrogen yearly application amount of CCF was 100.8 kg/hm2; that of CRF1 - 1, CRF1 -2, CRF1 - 3, CRF2 - 1, CRF2 -2 was 100%, 80%, 50%,100%, 50% of that of CCF respectively. The field experiment results were as follows. The application of CRF1 - 1 and CRF2 - 1 could remarkably increase the contents of available N, P, K in soil in spring and summer, but the nutrients in all treatments were in short supply in autumn. The application of CRF also could increase the photosynthetic rate, 100 -bud weight, amino acid content and reduce the ratio of polyphenol to amino acid so as to improve the quality of green tea in Shandong. The fertilizer application amount in Shandong young tea garden was in short supply. The experiment should be conducted continuously to make sure the best fertilizer application amount based on the CRF2 - 1 treatment.关键词
