蒙阴县位于沂蒙山区的西北部。花生是该地区主要作物之一,近年来每年播种面积13万亩左右,由于花生种植在地势高、土层薄、肥力低的岭砂土上,单产一直在125公斤上下徘徊,年际间产量波动较大。我们于1984—1987年在蒙阴县桃曲、联城、巨山等乡进行了花生优化栽培试验。四年来共布置试验78个,试验结果表明:在当前生产条件下,从品种、密度、化肥、有机肥及微肥等主要农艺措施入手,可以达到投资少、产量高、效益显著的目的。
Mengyin County is located in the northwest Yimeng Mountain. Peanut is one of the main crops in the region. In recent years, the annual sown area is about 130,000 mu. As the peanut is planted on the ridge of sandy soil with high topography, thin soil layers and low fertility, the yield has been hovering around 125kg. The annual output Fluctuations. In 1984-1987, we carried out peanut cultivation experiments in the peach songs, the cities of Liangyin and Jushan in Mengyin County. In the past four years, a total of 78 experiments have been arranged. The results show that under the current production conditions, starting from the major agronomic measures such as variety, density, chemical fertilizer, organic fertilizer and micro-fertilizer, low investment, high yield and significant benefit can be achieved.
