小麦磷肥早施,或用作基肥,比晚施、追施的效果好,可增加小麦苗期干物质的积累,为后期增加穗数、粒重提供物质基础。这是早已被证实的事。但在基肥施用技术上,如何促使小麦早期多吸磷,经济用磷,以提高单产,尚需进一步研究。因此,我们在天 As early as wheat phosphate fertilizer, or as a base fertilizer than late, topdressing effect is good, can increase the dry matter accumulation of wheat seedling, to increase the number of ears and grain weight to provide the material basis. This is already confirmed. However, in the application of basal fertilizer, how to promote the early wheat more phosphorus uptake, economic use of phosphorus, in order to improve yield, still needs further study. So we are in heaven
