山东省宁阳县泗店乡徐孟农科所生姜研究室科技人员,研究出生姜定向高密度平垄双行不培土栽培五改技术。该技术使生姜亩产由2500公斤左右,提高到4000—5000公斤,增产60—100％。 一、改东西行向姜种随意排放为南北行向东西排放。姜芽集中于沟中心,由于姜的扇面东西伸展,地上主茎叶片也系东西分布,主茎叶片可为子姜、孙姜幼芽遮光,可不再播姜草遮阳。 二、改大垄单行为平垄双行。传统栽培是大垄单行播种,既要培土,密度又低。新法是一垄双行,垄内小行距27厘米,大行距53厘米,播种时开 Ningyang County, Shandong Province, Xu Mengnong Si Branch Township ginger laboratory science and technology personnel, to study the orientation of ginger-oriented high-density flat ridge double line five cultivation techniques without cultivation. The technology allows ginger yield by about 2,500 kg, increased to 4000-5000 kg, an increase of 60-100%. First, change the east and west lines to the ginger kind of free discharge North-South line to the east-west emissions. Ginger bud concentrated in the ditch center, due to the expansion of ginger fan things, the ground is also the main stem of the distribution of things, the main stem leaves can be ginger, ginger buds shading, no longer broadcast ginger grass shade. Second, to change the behavior of flat ridge two lines. Traditional cultivation is a large ridge single sowing, it is necessary to earth, density and low. The new law is a two-ridge line, ridge within the small row 27 cm, 53 cm wide row, sowing open
