通过试验表明:配方施肥与常规施肥和对照〈空白〉比较,全生育期上苗的长势较强、整齐,拔节前常规施肥株高明显高于配方施肥及空白处理,拔节后收获配方施肥处理株高明显高于常规施肥、空白处理,产量配方施肥处理明显高于常规施肥、空白处理,增产幅度分别是17.2%、40.0%。配方施肥一定要根据土壤肥力及特性、水稻品种的需肥特点,掌握好施肥量和施肥比例及时间,才能达到提高农产品质量,降低生产成本,增加产品产量,从而达到增产增收目的。
The results showed that: Compared with conventional fertilization and control, the growth of upper seedlings in the whole growing period was stronger and neat. The conventional fertilization plant height before jointing was obviously higher than that of formula fertilization and blank treatment, and the fertilization treatment after jointing Plant height was significantly higher than the conventional fertilization, blank treatment, yield formula fertilization treatment was significantly higher than conventional fertilization, blank treatment, increase yield were 17.2%, 40.0%. Formula fertilization must be based on soil fertility and characteristics of rice varieties need fertilizer characteristics, to master the amount of fertilizer and fertilization and time, to improve the quality of agricultural products, reduce production costs, increase product yield, so as to achieve the purpose of increasing production.
