棉花塑料薄膜育苗移栽是夺取棉花早熟、优质、高产的栽培措施之一,已为众所公认。然而,这项措施的成败和增产幅度的大小在很大程度取决于育苗阶段棉苗的素质。由于移栽棉花播种的时间比直播的要提前一个月,风险较多,如果措施不当,会直接影响早苗、全苗、壮苗、早发。我们通过多年棉花塑料薄膜育苗的实践,体会到在育苗全过程中,必须紧紧抓住四个“一”,即选好一粒种,提高种子质量(粒选后用千分之二的25%多菌灵浸种);备好一堆土,提高床土质量(床土经过冬耕冻垡、春耕晒垡,
Cotton plastic film seedling transplanting is to seize cotton precocious, high-quality, high-yielding cultivation measures, has been well-recognized. However, the success or failure of this measure and the size of the increase will depend to a large extent on the quality of cotton seedlings at the nursery stage. As transplanting cotton sowing time than live one month in advance, the risk is more, if improper measures, will have a direct impact on sapling, all seedlings, strong seedlings, early hair. Through years of practice of cotton plastic film nursery, we have realized that in the whole process of nursery, we must grasp four “one”, that is, select one seed to improve seed quality (25% for grain selection % Carbendazim soaking); prepare a pile of soil, improve the bed soil quality (bed soil after winter plowing, plowing spring drying,
