摘要
采用盆栽试验,研究了施用生石灰对水稻产量及产量构成因素的影响。结果表明:生石灰对提高三系杂交稻的产量有积极影响,分别比对照提高了22.39%和17.77%,但对提高常规稻和两系杂交稻的产量作用不明显;在产量构成因素方面,施用生石灰能提高常规稻和两系杂交稻的结实率、提高两系杂交稻的每穗实粒数和千粒重,对三系杂交稻的产量构成因素有一定的积极影响。
A pot experiment was carried to study effect of using quick lime on yield and yield components of rice.The results showed that quick lime had a positive effect on improving yield of three-line hybrid rice,which increased by 22.39% and 17.77% than control;quick lime had not obvious effect on improving the yield of conventional rice and two-line hybrid rice;the application of quick lime can increase the seed setting rate of conventional rice and two-line hybrid rice and the filled grain number per panicle and the 1000-grains weight of two-line hybrid rice,and had some positive impacts on yield component factors of three-line hybrid rice.
