The Effect of Controlled-release Lanthanon Multiple Fertilization(Si-Ca) Used as Basal Manure on Rice Physiology and Yield

Rice growth duration,main agronomic traits,yield,chlorophyll,leaf area and photosynthetic influence were contrast under different treatments of controlled-release lanthanon multiple fertilization(Si-Ca) used as basal manure on rice drip irrigation under film,it draw conclusions that the effect were 50 kg/667 m270 kg/667 m230 kg/667 m2 blank control by using controlled-release lanthanon multiple fertilization(Si-Ca).
