| Abstract: | A new compound fertilizer, long effects all nutrient elements com pound fertilizer containing rare earth was made for increasing effects of compoundfertilizer on rice. This fertilizer was experimented on rice for 3 years ,and 10 fieldexperiments on it were conducted.Results obtained showed that A treatment,containing rare earth long effects all nutrient elements compound fertilizer,increased rice yield to 6 862 5 kg/hm 2,which was 496 5 kg/hm 2 more than B treatment which contained the same amount of N,P,K,but no rare earth.The rate of rice yield increase was 7 8%,and the difference between the two treatments reached extremely significant level according to statistics analysis. |
