花生产量的形成是品种遗传特性与环境条件共同作用的结果,植株在各个生长时期中的表现均对产量形成有重要影响。根据不同地区花生的栽培经验,高产花生群体的基本特征应包括如下几个方面。1.前期苗壮花生生长前期是以营养生长为主的阶段,包括出苗期和幼苗期两个生育时期。该阶段植株生长的总体要求是根深、叶浓、茎粗、节密。具体生育进程和生长指标 The formation of peanut yield is the result of the interaction between the genetic characteristics of the varieties and the environmental conditions. The performance of the plants in each growth period has an important impact on the yield formation. According to the peanut cultivation experience in different regions, the basic characteristics of high-yield peanut population should include the following aspects. 1. Pre-Miaozhuang peanut growth stage is based on the vegetative growth stage, including the emergence and seedling stage of two growth stages. The overall requirements of plant growth at this stage is deep root, thick leaves, stem thick, dense section. Specific fertility process and growth indicators
