针对寒地水稻的需肥特点，采用裂区试验设计，对惠满丰活性液肥在寒地水稻上的施用时期和施用量进行研究，试验结果表明，主处理３个水平间差异不显著，主处理与副处理间互作不显著，相互独立，以４期喷施（即分蘖期、幼穗分化期、始穗期、齐穗期）每次用量在２２５０ｍｌ／ｈｍ２左右时产量和效益较好。 According to the characteristics of fertilizer requirement in cold paddy field, the experimental design of split zone was used to study the application period and the application rate of Huifeng abundant liquid fertilizer in cold paddy rice. The results showed that there was no significant difference among the three main levels The interaction between treatment and sub-treatment was not significant and independent of each other. The yield and benefit were good when the dosage was about 2250ml / hm2 at the four spraying stages (tillering stage, young panicle differentiation stage, initial heading stage and heading stage) .
