高产优质大豆栽培技术体系的研究Ⅰ合丰42高产优质窄行密植栽培技术体系

Cultivation Technique System of High-yield and Superior Quality Soybean Ⅰ High-yield and Superior Quality Narrow-compact Planting Technique System for Hefeng No.42

通过小区栽培方式与栽培密度试验研究,得出合丰42大豆适宜45 cm小垄窄行密植栽培。合丰42高产优质窄行密植栽培技术体系经过大面积推广示范,5年13点平均产量3 323.2 kg.hm-2,比常规三垄栽培平均增产18.7%,增收大豆523.5 kg.hm-2。

The experiment of cultivation patterns and the density were researched in small area. The results indicated Hefeng No. 42 was suitable to plant under narrow-compact planting which row spacing was 45 cm. High-yield and superior quality narrow-compact planting technique system for Hefeng No. 42 soybean was set an example in big area,the average yield of 13 place in 5 years was 3 323.2 kg ·hm^-2 ,the yield was increased byl8.7% than that of ridge cultivation,that was to say,523.5 kg· hm^-2 more than that of ridge cultivation.
