大豆垄上三行“大垄密”栽培技术

Cultivation Technique of "Wide Ridge Dense Planting" in Soybean

介绍大豆110 cm垄上三行"大垄密"栽培技术,该技术是一项垄平结合、宽窄结合、旱涝综防的大豆栽培模式。主要解决阶段性降雨多或是土壤库容小,不能存放多余水的大豆栽培技术。在旱年比70 cm的三垄栽培能增产10%以上,在涝年比其他的大垄密栽培技术增产6%以上,常年其大豆产量能稳定保持在3 000 kg/hm2以上。

Cultivation technique of＂Wide Ridge Dense Planting＂is introduced. Soybean is planted three-rows in the 110 cm width ridge. This is a good cultivation model combining the effects of ridge and flat, width and narrowness as well as integrated control on drought and flood. This soybean cultivation technology solves the problems of excessive rainfall that can not be stored at certain growth stage or due to small soil water storage capacity. This cultivation technology can increase yield more than 10%than three-rows of 70 cm width ridge in the drought year and increase yield more than 6%than another technology of＂Wide Ridge Dense Planting＂in wet years. Soybean yield can remain stable at 3 000 kg/ha in a normal year.
