水稻专用生物复合肥效应

Effect of Special Biology Compound Fertilizer on Rice

为了进一步探索龙珠牌生物型有机无机复合肥对改良土壤、防治污染、增产提质的作用,在2001年度试验示范的基础上,2002年在普定县城关等6个乡镇进行了试验和200hm2示范。结果表明,每667m2施用生物复合肥50kg作底肥,追施多效奇2kg的处理A、B,分别比对照C增产稻谷31.1%、18.6%,增值147.5元、115.5元;大面积示范增产23.8%,增值112.5元/667m2。施用生物复合肥后,土壤pH值、有机质和稻谷P、K及粗蛋白质含量均有所提高。

On the basis of experiment and demonstration in 2001, experiments and 200ha of demonstration were carried out to search the effect of special biology compound fertilizer on soil improvement, prevention and cure of pollution, increasing yield and improving quality in six townships of Puding county in 2002. The results showed that the rice yields of treatment A and B, which were applied with 50 kg of special biology compound fertilizer as base fertilizer and 2 kg of growth regulator called Duoxiaoqi as supplemental fertilizer,were respectively increased by 31.1% and 18.6% compared with the contrast treatment C, the product values of A and B increased by 2212 yuan/ha and 1732 yuan/ha compared with treatment C. The yield and product value of the demonstration area increased by 23.8% and 1687 yuan/ha comared with CK respectively. The pH value and organic matter content of the tested soil, and contents of P, K and crude protein in rice seed all were improved after applying special biological compound fertilizer.
