为明确种植密度对不同株型花生单粒精播群体质量的影响,选用直立型大花生品种"花育22" (Huayu 22,HY22)和半匍匐型大花生品种"花育9513" (Huayu 9513,HY9513),设置D1(7.5万株hm~(-2))、D2(15万株hm~(-2))、D3(22.5万株hm~(-2))3个密度,对不同密度下不同株型花生产量、光合产物累积与分配、叶面积系数、植株性状和粒叶比进行了研究。结果如下:(1)随密度的增加,"花育22"荚果产量呈增加趋势,"花育9513"呈先升高后降低的趋势,"花育9513"最适种植密度低于"花育22"。(2)"花育22"植株群体干重整个生育期均随密度的增加而增加,密度越大增幅越小,"花育9513"幼苗期干重随密度的增加而增加,花针期之后随密度...

In order to clarify the effect of planting density on the population quality of peanut with different plant types under the mode of single-seed precision sowing, this experiment were carried out with two plant-types (erect big peanut variety “Huayu 22” and semi-creeping big peanut variety “Huayu 9513”), three densities (75,000 plants hm–2, 150,000 plants hm–2, and 225,000 plants hm–2). Yield, photosynthetic product accumulation and distribution, leaf area index, plant characteristics and grain leaf ratio were studied. The results were as...
