Abstract:

Pot experiments of rice were performed to study the effects of applying silicate and phosphorus on rice yield in phaeozem. Response surface methodology was used to analysis the various influences on rice panicle per unit area, average number of spikelets per panicle, rates of filled seeds and grain weight of 1000 spikelets by applying silicate fertilizer, phosphorus fertilizer and the interactions of them. Through study the author found that phosphate could had a significant impact on spikelets panicle and grain weight, application of silicon could significantly affect ears, spikelets panicle and grain weight, the interaction of both silicon and phosphorus can significantly affect spikelets panicle. After studied the silicon and phosphorus on rice production constitutes the basis of factors, the yield of rice was obtained by calculating silicon and phosphorus fertilizer application rate of regression model, according to the model to determine the highest production and output conditions were as follows: monoammonium phosphate 1.68 g, sodium silicate 5.25 g, the theoretical product was 91.74 g, however the true product was 71.74 g which was higher 53.32 percent than the output by control treatment.
