据我们两年试验,秧田用氮素化肥作面肥比用等量肥料作断奶肥对培育壮秧的效果好。秧田面肥的施用方法是:在施足秧田有机基肥的基础上,经过耕耖晒垡,干平干整,做成通气湿润秧板,于上水验平沉实后,将秧田放半沟水,每亩用尿素10斤左右或硫酸铵20斤左右均匀施于板面,用钉耙将肥料与表层土壤充分混合,再用推光板推平板面即可落谷。秧田施用面肥的好处有:(1)方法简便,肥料集中,不易流失。特别对早播覆盖的秧田,可克服因断
According to our two years of experiments, seedling with nitrogen fertilizer for surface fertilizer than with the same amount of fertilizer for weaning seedling cultivation of good effect. Seedling field fertilizer application method is: on the basis of foot-seedling organic basal fertilizer, after tillage drying sunburn, dry-level dried, made of ventilated wet seedbed, in the water level test, the seedling put half a ditch water , About 10 pounds of urea per acre or about 20 kg of ammonium sulfate evenly applied to the board surface, with a rake to fertilize the surface soil and fully mixed, and then push the board to push the flat surface to the valley. The benefits of applying surface fertilizer in seedling are: (1) The method is simple, the fertilizer is concentrated, and the loss is not easy. In particular, early seedling coverage of seedlings, can overcome due to broken
