高产油菜必须有足够的个体数量,同时要提高群体内各个体的质量,协调个体与群体生长,促进油菜生长水平的不断提高。本试验在其他栽培条件相同的前提下,通过油菜不同移栽密度试验,试图明确移栽密度与产量的关系,寻求在目前栽培水平下的最适移栽密度。1996～1997年度的试验结果总结如下。1试验材料与方法 试验地点设在阳澄湖镇,前茬水稻,油菜供试品
High-yielding rape must have a sufficient number of individuals, at the same time to improve the quality of the various groups within the individual, to coordinate the growth of individuals and groups, and to promote the continuous growth of rape growth. Under the same conditions of other cultivation, this experiment tried to find out the relationship between the transplanting density and the yield through the different transplanting density test of rape and seek the optimal transplanting density under the current cultivation level. The test results from 1996 to 1997 are summarized as follows. A test materials and methods The test site is located in Yangcheng Lake, the former crop rice, rape for the test
