摘　　要：采用单粒精播、小垄单行和双粒穴播、大垄多行的5种种植方式,对旱薄地夏直播花生植株生长发育状况和产量性状的影响进行了研究。结果表明,单粒精播、小垄单行和幅宽140cm以上、双粒穴播4～5行的大垄多行种植方式可明显促进开花期前叶片、茎等地上部营养器官的生长,叶面积系数增加、光合产物积累增加;结荚后,单粒精播、小垄单行的种植方式光合产物积累和光合面积下降缓慢,在幼果数量上仍保持明显优势,但大垄多行的种植方式的光合产物和光合面积下降迅速、秕果数量显著增加,致使产量降低。旱薄地夏直播花生推荐单粒精播、小垄单行或幅宽110cm、双粒穴播3行的种植方式,可提高产量5%～13%。The experiment focused on effects of planting seeding peanut in arid and low production hilly regions patterns on growth and yield of summer direct Five patterns, including single-seed precision sowing, single row of the narrow ridge, double grains per hole sowing and rows of the wide ridge, were chosen for the research. The results indicated that above-ground organs growth, leaf area index and accumulation of photosynthetic products addition were promoted significantly by single-seed preci- sion sowing, single row of the narrow ridge with the width of 140 cm more and wide ridge and 4-5 rows combined with double grains per hole sowing, especially before flowering stage. Meanwhile, photosynthetic products accumulation and green leaf area under the first two patterns decreased slowly after podding stage, and maintained marked superiority in unfilled pod number. However, rows of the wide ridge pattern results showed in opposite direction, to gain low yield. Above all, there were three planting patterns recommended in arid and low production hilly regions, including single-seed preci-sion sowing, single row of the narrow ridge or width with 110 cm, and wide ridge and three rows with double grains per hole ones.
