摘要
为探索种植模式对藜麦生产的影响,本试验通过比较藜麦在开沟直播、育苗移栽和覆膜点籽3种不同栽培模式下农艺性状、产量及产量构成因素的表现,并分析不同栽培模式的经济效益。结果表明,藜麦育苗移栽的全生育期较短,株高较高;产量及产量构成方面,单位面积株数以开沟直播最多,覆膜点籽最低;单株穗重以育苗移栽最高,开沟直播最低;千粒重以育苗移栽最高,开沟直播最低;育苗移栽的藜麦产量较其他两种栽培方式高,差异具有统计学意义(P<0.05);3种模式的藜麦经济效益存在差异,以育苗移栽最高,覆膜点籽最低。综合评价发现,育苗移栽模式安全且经济效益较高,适宜于藜麦规模化种植生产,开沟直播模式适宜于生产条件一般的山坡丘陵地区藜麦种植生产。
To explore the impact of planting models on quinoa production,the agronomic traits,yield,and yield components of quinoa under 3 different cultivation models:trenching direct seeding,seedling transplanting,and mulching seed planting were compared,the economic benefits of different cultivation models were analyzed.The results showed that the entire growth period of quinoa seedling transplanting was shorter and the plant height was higher.In terms of yield and yield composition,the number of plants per unit area was highest in ditching direct seeding and lowest in mulching seed planting.The weight of individual spikes was highest during seedling transplanting and lowest during trenching and direct seeding.The highest thousand grain weight was achieved through seedling transplanting,while the lowest was achieved through trenching and direct seeding.The yield of quinoa transplanted from seedlings was higher than the other two cultivation methods,and the difference was statistically significant(P<0.05).There were differences in the economic benefits of quinoa among the 3 models,with the highest being seedling transplanting and the lowest being mulching seed planting.The comprehensive evaluation found that the seedling transplanting model was safe and had high economic benefits,suitable for large-scale planting and production of quinoa,the trenching direct seeding model was suitable for quinoa cultivation and production in mountainous and hilly areas with average production conditions.
