为了探索水稻专用肥配方,以水稻为供试作物,在建三江研究所试验地进行黑龙江省农业科学院土壤肥料与环境资源研究所研制的高效硅肥应用效果试验。结果表明:施用硅肥不仅促进了水稻植株的提前成熟,增加了抗倒伏能力,而且提高了叶绿素含量。更有利于光合产物的积累和籽粒的充实,降低了空秕率,从而提高了水稻的产量。其中硅肥Ⅰ(基肥施用高效硅肥225kg·hm-2,追返青肥30kgN·hm-2,追穗肥30kgN·hm-2+30kg K2O·hm-2)和硅肥Ⅱ(基肥施用高效硅肥375kg·hm-2,追返青肥16kgN·hm-2,追穗肥24kgN·hm-2+24kg K2O·hm-2)两个处理比常规施肥分别增产14.5%和10.1%。
In order to explore the special fertilizer formula for rice, rice was used as the test crop, and the effect experiment of high-efficiency silicon fertilizer developed by Soil and Fertilizer and Environment Resource Institute of Heilongjiang Academy of Agricultural Sciences was experimentally conducted at Jianjiang Sanjiang Institute. The results showed that the application of silicon fertilizer not only promoted the premature maturation of rice plants, increased the lodging resistance, but also increased the chlorophyll content. More conducive to the accumulation of photosynthetic products and grain enrichment, reducing the empty rate, thereby increasing the yield of rice. Silicone fertilizer Ⅰ (225kg · hm-2 of high efficient silicon fertilizer applied on base fertilizer, 30kgN · hm-2 of reclaimed green manure and 30kgN · hm-2 + 30kg K2O · hm-2) 375kg · hm-2, 16kgN · hm-2 of chasing green manure and 24kgN · hm-2 + 24kg K2O · hm-2 of chaihuizui. Both treatments increased yield by 14.5% and 10.1% respectively compared with conventional fertilization.
