玉米营养钵矮化育苗移栽技术(以下简称营养钵育苗)是我县引进和学习陕西省安康地区“旱地玉米高产栽培”的经验。这项技术通过玉米在育苗过程中水分和温度的控制及对钵体的移位而截断须根系等措施,有效地控制了玉米苗期节间的伸长(蹲苗),使苗矮而壮,抗性增强,并且减少了养分的消耗。同时还可以部分地替代地膜玉米,减少由于废地膜在土壤中的残留富集而造成土壤污染和理化性质劣化,是继地膜之后又一项很有推广价值的旱地玉米高产栽培技术。为使这项技术迅速推开,发挥效益,我们在1990～1991年进行了试验示范。
Corn nutrition bowl dwarf nursery transplanting technology (hereinafter referred to as nutrition Bowl nursery) is the introduction and study of our county in Ankang, Shaanxi Province “dry land high yielding cultivation of maize” experience. This technology effectively controls corn elongation at the seedling stage (squatting seedlings) by controlling the moisture and temperature of the corn in the seedling raising process and truncating the fibrous roots in response to the displacement of the pot body, so that the seedlings are short and strong, Increased resistance, and reduced nutrient consumption. At the same time, it can also partially replace the mulched corn and reduce the soil pollution and the degradation of physicochemical properties due to the residual enrichment of waste mulching film in the soil. It is another high-yielding cultivation technique of dryland maize after the mulching film. In order to speed up the technology and bring benefits, we conducted pilot demonstrations in 1990-1991.
