通过对分厢带植的带距带比(A)和作物间套组合(B)两因素的随机区组试验的研究,结果表明:(1)丘陵旱地分厢带植以宽带最好,带距带比以双2m(双6尺)模式(A3)最佳,双1.67m(双5尺)模式(A2)次之。(2)作物间套组合以“小麦+(蚕豆+春菜)/春玉米-秋菜/甘薯+夏玉米”组合(B2)最佳,“小麦+春菜/春玉米+大豆/甘薯”组合(B3)次之。(3)双2m(双6尺)、双1.67m(双5尺)宽带模式宜在地势较平坦,土层较深厚肥沃,地块较大的丘陵一、二台上上应用推广。间套组合B2在双2m(双6尺)上的应用效果优于双1.67m(双五尺)。中带型双0.83m(双2.5尺)模式(A1)宜在丘陵小块坡台地和三台地上推广,应根据生产条件和土壤地力,灵活来用B2,B3间套组合。(4)A3B2,A2B2,A1B2,B1B3是筛选出的4个兼具粮、菜、饲并重特点的分厢带植高产高效种植模式。其中,A3B2,A2B2的全年粮食667m2产均超吨粮,667m2产值和纯收益均超双千元。
The results of the randomized block test with two factors of distance ratio (A) and intercrop space (B) in the boxing system showed that: (1) The best ratio of belt to double 2m (double 6-foot) mode (A3), followed by double 1.67m (double 5-foot) mode (A2). (2) The combination of crops ("B2 + + + + + + spring vegetable + Second. (3) Double 2m (double 6 feet) and double 1.67m (double 5 feet) Broadband mode should be flat on the topography, with deeper and more fertile soil and larger poplars on the first and second stations. The utility model combination B2 is more effective than double 1.67m (double five feet) on double 2m (double 6 feet). Belt type double 0.83m (double 2.5 feet) mode (A1) should be in the hills and slope platform and three to promote the ground, should be based on production conditions and soil fertility, flexibility to use B2, B3 sets of combinations. (4) A3B2, A2B2, A1B2 and B1B3 are four high-yielding and high-efficiency cropping modes with the characteristics of grain, vegetables, feeding and weight selected. Among them, A3B2, A2B2 annual grain production are 667m2 tons of super-grain, 667m2 output value and net income are super two thousand dollars.
