| 摘 要： | 研究了4种栽培模式对水稻生长发育和产量的影响,结果表明:改向大垄产量明显高于其他三种栽培模式。改向大垄有效地改善了群体通风透光条件,使个体生长更有利于收受光照,从而延长下位叶功能期,有利于光合产物的增加。改向大垄分蘖成穗率、结实率、穗粒数分别比正常栽培高18.1%、5.1%、9.6。

| Abstract: | The influence of four planting patterns on growth and yield of rice was studied.The results indicated that yield of planting pattern of changed row direction and increased row distance was higher than other planting patterns.The planting pattern of changed row direction and increased row distance was effectively improving the air and light conditions of population,and more conducive to acceptance of light for individual growth,thus prolonging the function of lower leaves and increased the carbohydrates.Compared with normal planting pattern,the effective panicle rate of tiller,seed setting rate and grains per panicle of planting pattern of changed row direction and increased row distance were 18.1%,5.1% and 9.6 higher,respectively. |
