1试验设计1.1设计方法本试验采取国内外科研试验最常见的3414试验方案,以N、P、K三个因素为基础,以当地农户一般施肥量为依据,建立4个施肥水平,0水平为不施肥,2水平为当地最佳施肥量的近似值,1水平=2水平×0.5,3水平=2水平×1.5。试验设计小区长6m,宽3.5m,小区面积21m~2。小区采用随机排列的方法,每个处理设三个重复,共14个处理,各处理设计见表1。1.2施肥方法基肥:60%的氮肥,40%的钾肥,全部磷肥。苗期施10%的氮肥,10%的钾肥。现蕾期施30%的氮肥,50%
1 Experimental Design 1.1 Design Method This experiment adopts the most common 3414 experimental program of scientific research at home and abroad. Based on N, P and K factors and based on the general fertilization rate of local farmers, four fertilization levels No fertilization, 2 levels for the local optimum fertilization approximation, 1 level = 2 level × 0.5,3 level = 2 level × 1.5. The experimental design area is 6m long and 3.5m wide with a plot area of 21m ~ 2. The plot is arranged by random method, with three repetitions for each treatment, a total of 14 treatments. The design of each treatment is shown in Table 1.1.2 Fertilization Method Basal fertilizer: 60% nitrogen fertilizer, 40% potassium fertilizer and all phosphate fertilizer. Seedling application of 10% nitrogen fertilizer, potassium fertilizer 10%. Stem 30% of the application of nitrogen fertilizer, 50%
