配方施肥对春季桑叶1-脱氧野尻霉素产量的影响
Springtime DNJ yield in mulberry leaves with NPK fertilizer treatments
摘要
Abstract
To scientifically increase the 1 -deoxynojimycin (DNJ) yield of mulberry leaves in spring, a "3414" fertilizer experimental design with the DNJ yield of mulberry leaves as the objective function and fertilizer levels of N, P, and K as treatments was established. N, P, and K treatment levels were utilized and simulated with a regression applying to SPSS 11.5. The variance analysis between fertilizer rate and DNJ contents in mulberry leaves were treated by statistical analysis applying to SAS 9.0 DA software. Results showed, that the DNJ content significantly increased (P <0.05) with the level 240.0 kg·hm-2 (N), 84.0 kg·hm-2 (P2O5), 120.0 kg·hm-2 (K2O) fertilizer treatment. The optimum recommended fertilizer was 286.1 kg·hm-2 (N), 95.2 kg·hnT2 (P2O5) , and 159.6 kg·hnT2 (K2O) with an optimum economic yield of 23.23 kg·hm-2. After confirmation in actual conditions, this optimum fertilizer design could increase the high yield and quality of mulberry leaves in the hilly areas of Sichuan Province.
