我区土壤除沿嘉陵江、渠河两岸部分土质带沙外,其余大多土质粘重,整地困难。在土粘缺肥的情况下,稻田种麦究竟采取什么播种方式好?1978年秋播时,我们在全区选择了有代表性的田或土用“凡六”作对比试验,结果表明:在泥田粘土条件下,以小窝密植的连窝点播或撬窝点播方式最好,条播次之。田里净作连窝点播或撬窝点播亩产560—628.3斤,比条播增产6—40％;土里预留行间种连窝点播或撬窝点播亩产248—423斤,比条播增产10—20％,与大田生产趋势一致。 (见表)
In addition to along the Jialing River along the Jialing River and the part of the Drainage River, some of the soil in the area is sandy. The rest of the soil is so thick that it is difficult for soil preparation. In the case of soil-sticking and lack of fertilizer, what kind of sowing method is better for paddy field wheat? In the autumn of 1978, we selected a representative field or soil “van-six” for comparison test in the whole area. The results showed that in the Under the condition of clay soil in the clay soil, the on-demand or prick-proofed on-demand method is the best one with even the densely-packed seedlings in the pit and the second is the seed-boring. Field net for even the nest on-demand or pry nest on-demand sowing 560-628.3 kg, 6-40% yield increase than the strip; soil reserved for inter-row seed or pith nest sowing mu 248-423 kg, 10-20%, consistent with the trend of field production.
