A look at soil properties of low-lying land and saline-alkali land to use ammonium sulfate, superphosphate and other acidic fertilizers; acid soil should use urea, ammonium bicarbonate and other alkaline fertilizers; for the preservation of water, poor fertilizer capacity of sand land should use non-volatile urea And other fertilizers.

Second, the characteristics of fertilizers should be avoided by shallow application, explicit application, or with water, so as to avoid loss of fertilizer efficiency and waste.

Thirdly, seedlings that need 6-7 leaf lengths should be fertilized according to their strains. Fertilizers should be applied during the jointing stage; the amount of fertilizers at the booting stage should be increased, and foliar fertilizer should be sprayed in the middle stage, and potassium dihydrogen phosphate should be sprayed during the seed stage.

Four to look at growing strong seedling plots can be applied fertilizer; weak seedling plots in addition to chemical fertilizers but also after the application of good decomposing manure, cake fat; to strong seedlings in the plots of weak seedlings to eat rice, more fertilizer, so weak seedlings change strong. After fertilization, cover the soil with deep cultivator.

See fertility law at seedling stage 5, do not fertilize too early to facilitate the seedlings; fertilization can not be late in the formation stage of males and females, to prevent the emergence of old seedlings; appropriate amount of fertilizer in the late period, to prevent early decline in production.
