播种期和种植密度对沙蓬农艺性状和产量的影响

Effects of sowing date and planting density on agronomic characters and yield of Agriophyllum squarrosum(L.)Moq.

以沙蓬[Agriophyllum squarrosum(L.)Moq.]为材料,研究人工种植条件下沙蓬的生育期和农艺性状,以期获得最佳的人工种植条件。研究了不同播种期、施肥类型和播种量对沙蓬生育进程、产量和产量构成因素的影响,以期探索沙蓬在宁夏沙荒地适宜的播种期、施肥类型和播种量。结果表明,沙蓬适宜在5月上旬播种,播种量为7.50~15.0 kg/hm^(2);当种植密度为12.00 kg/hm^(2)时,施复合肥沙蓬产量可达到779.1 kg/hm^(2),与其他处理间存在明显差异。因此,可以通过人工种植来改变沙蓬的农艺性状。

In order to obtain the best artificial planting conditions,using the Agriophyllum squarrosum(L.)Moq.as the material,this paper studied the growth period and agronomic characters of Agriophyllum squarrosum(L.)Moq.under artificial planting condition.The effects of different sowing dates,fertilization types and seeding amounts on the growth process,yield and yield component factors were studied to explore the suitable sowing date,fertilization type and seeding amount of Agriophyllum squarrosum(L.)Moq.in Ningxia sandy wasteland.The results showed that the seed rate was 7.50~15.0 kg/hm^(2) in early May.When the planting density was 12.00 kg/hm^(2),the yield could reach 779.1 kg/hm^(2) under the compound fertilizer application,which was significantly different from other treatments.Therefore,the agronomic traits of Agriophyllum squarrosum(L.)Moq.could be changed by artificial planting.
