近年来,在创高产模规律的研究和生产实践中,证明花生壮苗是高产的基础,而苗的壮弱与栽培条件,管理水平和种子的发育等因素有关。本研究属高产栽培规供试品种为徐州68—4。种子分别过8、7、6mm筛,选出一级种子百仁重为117、8—120.3克,二级种子为91.0—93.8克,三级种子为60.0—62.6克。采用顺序排列法,重复5次,第1重复为取样区。小区长21尺,宽5.6尺,4行区,行距1.4尺,穴距0.7尺,每亩6122墩,双粒播种。
In recent years, it has been proved that strong peanut seedlings are the basis of high yield in the research and production practice of high-yielding molds. The weakness of seedlings is related to the cultivation conditions, management level and seed development. This study is a high yielding cultivation test varieties for Xuzhou 68-4. Seeds were 8,7,6 mm sieve, respectively, selected a seed weight of 117,8-120.3 grams, two seed 91.0-93.8 grams, three seeds 60.0-62.6 grams. The order of arrangement, repeated 5 times, the first repeat for the sampling area. The district is 21 feet long and 5.6 feet wide. The 4-row area has a row spacing of 1.4 feet and a hole distance of 0.7 feet with 6122 piers per mu.
