Dynamic Changes of Soil Temperature in Wheat spring Cotton Relay Cropping System during Theirs Common Growing Period

麦套春棉共生期间土壤温度的动态变化

Many county-level TV stations have become relay stations for Spring Festival evening parties.

许多县城的电视台变成了春节晚会的转播台.

Field experiment method was adopted in this peper to study the rational fertilizer amount and the compostion applied to the relay croped spring corn in the wheat-corn-rice triple cropping system in the South Jiangsu district.

采用田间试验的方法，对苏南地区麦玉米稻三熟制中套作春玉米的合理施肥量和肥料配比进行了研究。

But at N2, the crude fat yield of spring-sown maize in relay intercropping system was higher than that of sole cropping; and no significant differences were observed between the crude protein yield of summer-sown maize relay intercropping and that of sole cropping.

但在N2条件下，春玉米全株粗脂肪产量高于单作，夏玉米全株粗蛋白产量与单作差异不显著。
