甘蔗育苗移栽有增产、省种苗、早熟等优点,已为我国蔗区的试验和生产实践所证明,现也逐渐应用于甘蔗生产上。为了进一步提高育苗移栽的良好效应,我们对甘蔗育苗期进行不同施肥处理,探讨其对蔗苗质素的影响及移栽后生长的效应,以及营养钵育苗与露地育苗的蔗苗在形态生理上及移栽后生长的差异等几方面进行了研究,为提高蔗苗移栽成活率,缩短滞长期和提高甘蔗育苗移栽的早熟、增产效果,提供理论和实践的依据。材料与方法一、育苗期肥料施用效应试验 (一)氮肥的施用以亩施过磷酸钙及氯化钾各10斤作基肥,育苗期亩施硫酸铵20斤作追肥,分3种处理:
Sugarcane seedling transplanting with yield, the province seedlings, precocious advantages, for our sugarcane trial and production practices have proven, and now also gradually applied to sugar cane production. In order to further improve the transplanting seedling good effect, we have different fertilization treatment of sugarcane seedling stage to explore its impact on the quality of sugarcane seedlings and transplanting growth effects, as well as nutritional bowl nursery and field nursery sugarcane seedlings in the morphological and physiological And the differences in the growth after transplanting, etc. Several studies were carried out to provide theoretical and practical basis for improving the transplanting survival rate of sugarcane seedlings, shortening the hysteretic period and improving the precocious and increasing yield of transplanting sugarcane seedlings. Materials and methods First, the effect of fertilization seedling test (A) the application of nitrogen Fertilization of calcium phosphate and potassium chloride per kilogram of 10 kilograms of base fertilizer, mu of ammonium sulfate 20 pounds for top-dressing, divided into three kinds of treatment:
