一、磷肥作种肥效果好油菜是喜磷作物,施用磷肥对培育壮苗和提高产量具有十分明显的效果。施用磷肥的油菜,苗期生长快,冬前根系粗大,抗冻、耐旱能力增强,分枝、结角多,一般增产15—20％。每斤过磷酸钙增产油菜二、三斤。磷肥的施用方法,最好结合套种时沟施,每亩以二、三十斤为宜,如果每亩再增施五斤尿素或十斤硫铵,更能发挥磷肥肥效。二、施用“五四○六”菌肥增产显著“五四○六”菌肥不论作基肥或追肥,都能促进油菜根系发育,分枝多,产量高。
First, the effect of fertilizer for seed fertilizer Good rape is phosphorus-like crop, the application of phosphate fertilizer to cultivate strong seedlings and increase production has a very significant effect. The rapeseed with phosphate fertilizer had fast growth at seedling stage, coarse root system before winter, enhanced ability of frost resistance and drought tolerance, and more branches and nods, generally increased yield by 15-20%. Per kg of superphosphate increase rape two or three jins. Phosphate fertilizer application method, the best combination of intercropping ditch Shi, per acre to two or three pounds is appropriate, if the additional five pounds of urea per mu or ten pounds of ammonium sulfate, phosphate fertilizer to play more effective. Second, the application of “5406” significant increase in bacterial fertilizer “5460” Bacillus manure, whether as a base fertilizer or dressing, can promote rape root development, more branches, high yield.
