Abstract
The cold tolerant rice varieties Jijing 81 and Changbai 9 were used to simulate low temperature condition in rice transplanting periods,with different phosphate fertilizer gradients in artificial climate facilities.The growth and yield components of the two rice varieties under low temperature stress were examined.Low temperature in transplanting period could affect the growth of Japonica 81 and Changbai 9 seedlings and lead to the reduction of the maximum number of tillers,delay of the maximum tiller time and slower speed of new leaves growth.However,if appropriate amount of phosphate fertilizer was added in the bed soil under low temperature,the maximum number of tillers in creased by 19.7% and 27.4%,new leaves in creased by 8.55% and 10.7%,the maximum tillering time reduced by 2.7d and 3.9d,expansion rate of stalk in maturity was shorten by 9.15 and 10.40%.The low temperature in transplanting period caused output decrease of Jijing 81 and Changbai 9 in many aspects such as panicles per hill,grains per panicle and grain weight,among which the influential order followed as grains per panicle panicles per hill grain weight.However,after adding phosphate fertilizer in the bed soil,the above factors increased greatly for the two varieties.Based on the yield and other influential factors,the optimal phosphates in bed soil for Jijing 81 and Changbai 9 were 61.69~71.18g·m-2 and 60.35~68.02g·m-2 respectively.It could reduce the bad effect on the growing process in rice under low temperature stress.
