移栽玉米的缓苗期长短,对玉米的早发、早熟、高产有很大影响.近两年我站对营养钵育苗移栽玉米缩短缓苗期进行了几项试验,主要结果如下:(一)茬口对缓苗期的影响试验在豆麦夹种茬和纯麦茬上进行,重复两次.两种茬口同于4月15日移栽,移栽时平均株高20.2厘米,茎粗0.4厘米,可见叶4.03张.5月10日调查,在同样栽培管理水平下,豆麦夹种茬玉米苗比纯麦茬玉米苗株高增10.3厘米,叶片多0.7张,茎粗增0.21厘米.而且80%的植株于4月21日出现新叶,
Transplantation of corn seedling period, the early onset of corn, early maturity, high yield has a great impact on the past two years I station on the nutrition Bowl transplanting corn shortening slow seedling conducted several tests, the main results are as follows: A) stubble on the impact of rejuvenation The experiment in beans and wheat stubble stubble and pure stubble, repeat twice.The same stubble on April 15, transplanting, transplanting average height 20.2 cm, stem diameter 0.4 Cm, visible leaves 4.03 May 10 survey, the same level of cultivation and management, beans and wheat clip seedling corn stalks higher than pure wheat stalks increased by 10.3 cm, leaves more than 0.7, stalks increased by 0.21 cm. Eighty percent of the plants showed new leaves on April 21,
