三江平原位于我国黑龙江省东部,总面积约为10万余平方公里的沼泽化平原,是我重点开发和治理的粮食基地之一。三江平原垦区大面积垦植于五十年代末和六十年代初期,近30多年的种植历史.土壤正在熟化过程中。由于水、旱等自然条件与人为因素的多种影响,致使农业生产状况不够稳定,为尽快改变目前高投入. Sanjiang Plain is located in the eastern part of Heilongjiang Province in our country, with a total area of ​​about 100,000 square kilometers of swampy plains, which is one of the grain bases that I focus on developing and managing.

Owing to the multiple influences of natural conditions such as water and drought and human factors, the status of agricultural production is not stable enough to change the current high investment as soon as possible.
