啤酒大麦“24561”公顷产6000kg的栽培技术研究

Study on high yield (6t per hectare) cultural techniques of beer brewing barley strain “24561”

以优质啤酒大麦“２４５６１”为试材，进行高产栽培技术研究，建立了产量与施氮量、施磷量、公顷基本苗数间的数学模型。依据此模型，每公顷施纯氮２２５ｋｇ、Ｐ２Ｏ５１５０ｋｇ、基本苗２２５万时，产量可稳定达到６ｔ以上；

In this paper, a new strain “24561” of good quality beer brewing barley was used as experimental material, and its high yield cultural techniques were studied. A kind of mathematical model was also established among grain yield and application amount of N, application amount of P, basic seedlings per hectare. On the basis of this model, in order to produce higher yield(over 6t per hectare), the most proper application amounts of N, P per hectare were 225kg, 150kg, the basic seedlings per hectare was 2 25 million.
