经多年多点试验,我们摸索出了一套亩产850公斤玉米的栽培技术。主要技术措施是:一、采用大、小行及株、行距数据1、大行距70—80厘米,不小于70厘米,小行距40厘米。2、株距40厘米,株距要灵活掌握,光照好的地边地头可以连续留2穴或3穴双棵,里边再按株距40厘米单棵留苗。二、播前准备要选叶片紧凑型或半紧凑型抗逆性强的玉米种;选生育期能适应本地区的高产品种,(播种前去除小粒、秕粒、破损粒及发霉粒,为保证苗齐、苗壮打好基础)。亩播种量2.5—3公斤(保证足苗,是高产稳产的关键,禁止查苗、补苗、补栽)。
After many years of trial, we explored a set of 850 kg per mu corn cultivation techniques. The main technical measures are: First, the use of large, small lines and strains, row spacing data 1, 70-80 cm wide row, not less than 70 cm, 40 cm small row spacing. 2, plant spacing 40 cm, plant spacing to be flexible to grasp, the light to the ground can continue to stay 2 or 3 holes Shuangka, which according to the plant spacing 40 cm single Miao Miao. Second, the sowing before the election to choose leaves compact or semi-compact strong resistance of corn species; choose growth period to adapt to the region’s high-yielding species (sowing before removal of small grains, grains, damaged grains and moldy grain, to ensure Miao Qi, Miao Zhuang lay the foundation). Acreage of 2.5-3 kg of sowing (to ensure enough seedlings, is the key to high and stable yield, check for seedlings, make up for seedlings, replanting).
