大豆浅翻深松高产栽培技术体系的初步研究

Preliminary Study on the High Yielding Cultural Technique System of Surface Ploughing and Deep Digging for Soybean

本文阐明了在三江平原区域采取浅翻深松耕作措施．可有效地改善土壤耕作层及心土层的物理性质，增加了土壤全量及速效养分，抗涝防旱效果显著，促进大豆生长发育，综合其它高产技术，显著提高大豆产量，为三江平原区域低湿地大豆单产水平提高找到了有效途径。

This paper illustrated, oil Sanjiang plain,surface ploughing and deep digging could effectively improve the physical property of plough layer and subsoil, increase the total and rapidly available nutrients.resist waterlogging, prevent drought and promote the growth of soybean and could obviously increase the yield of soybean with the combination of other high yielding techniques.This provided a effective way for raising the unit yield level of soybean on loW-wet land of Sanjiang plain.
