不同种植密度对高油酸花生机收特性及产量的影响

Effects of Different Planting Densities on High-Oleic Acid Peanut Yield and Machanized Harvest Characteristics

以菏花11号为材料,设置不同密度处理,研究其对高油酸花生植株发育、产量及机收特性的影响。结果表明,每公顷密度为36.0万株、42.0万株时,菏花11号各植株性状发育适中,株型紧凑,主茎高40 cm左右,侧枝长45 cm左右,有效分枝比例91%,倒伏率略大于10%;单株荚果发育较好,且果柄长度小,结果集中,收获期主茎绿叶数适中。因此,菏花11号每公顷密度(36.0~42.0)万株时,既能保障丰产又适宜机收。

With Hehua 11 as test material,different planting densities were set to study their effects on plant development,yield and mechanized harvest characteristics of high-oleic acid peanut.The results showed that when the planting density was 360 thousand and 420 thousand plants per hectare,the characters of each plant developed moderately with compact plant type,about 40-cm main plant height,about 45-cm branch length,91%of effective branch ratio,and slightly over 10%of lodging ratio;and the development of pods per plant was better,the fruit stalk was short,the podding was concentrated,and the number of green leaves of main stem was moderate in the harvest period.Therefore,when the density of Hehua 11 was between 360 thousand and 420 thousand plants per hectare,it could not only guarantee high yield,but also be suitable for mechanized harvesting.
