为了摸清满足高赖氨酸玉米生长条件的高产栽培措施,特进行本试验,以便在高赖氨酸玉米品种推广时做到良种良法一起推,为创高产提供科学依据。一、材料和方法 (一)、材料:经1986年比较试验选出的三个高赖氨酸玉米优良杂交组合A(046×6)、D(046×20)、M(068×19)为1987年栽培试验材料。 (二)、方法:采用4×3正交试验设计(L_9(3~4)],即:设四因素各具三个水平的试验。A因素为杂交组合,分A_1、A_2、A_3三个水平(A、D、M);B因素为播 In order to find out the high-yielding cultivation measures to meet the high-lysine corn growth conditions, this experiment was carried out to promote the high-lysine corn varieties together with good varieties and good method to provide a scientific basis for high yield. Materials and Methods (I) Materials: Three high-lysine hybrids A (046 × 6), D (046 × 20) and M (068 × 19) were selected from the comparative experiments in 1986 1987 cultivated test material. Methods: 4 × 3 orthogonal experimental design (L_9 (3-4)] was used to establish four experiments with three factors: A. A hybrid was composed of three A_1, A_2 and A_3 Level (A, D, M); B factor is broadcast
