【摘要】 以华南农业大学培育的糯小麦新品种华糯1号为材料,通过小区试验和大田生产试验,分别探讨了稻田套种和稻田直播两种栽培模式对其产量的影响,结果表明:糯小麦新品种华糯1号稻田套种,以浸种24 h后播种较干种直播效果好,小麦与水稻的共生期以水稻收获前12 d,或小麦长出1叶1心为宜,共生期过长不利于小麦的生长会导致减产;糯小麦华糯1号在水稻收获后直播栽培,0.51 hm2试验田的生产性试验平均公顷产量3 645 kg,较使用农家种和传统栽培方式产量翻了1倍多。更多还原

【Abstract】 Huanuo 1 was a new wax wheat line developed by south China agricultural university for 7 years.Based on the plot trial and field producing experiment,effects on the yield of wax wheat Huanuo 1 were studied by intercropping with rice and direct seeding after rice harvest.The results showed that as for the intercropping experiment of wax wheat Huanuo 1 with rice,the seed soaking for 24 hours before seeding was better than that without soaking and the optimum symbiotic period was 12 days before rice harvest or before the stage of one mature leaf and one new leaf of wax wheat,too longer symbiotic period was not good for wheat growth and would lead to reduced yield;under the experiment of direct seeding after rice harvest,the yield of 3 645 kg per hectare of wax wheat Huanuo 1 was produced over 0.51 hm2 field,which was more than two times of the yield using the farmer’s wheat varieties under traditional cultivation way.更多还原
