近年来日本在水田改旱田时,多将荞麦列入轮作体系,这已经成为荞麦栽培的主要方向,然而做到长期稳产并非易事。水改旱种荞麦,成败关键在于对湿害的防治。荞麦产量低,每10公亩仅产100公斤左右。其原因是:荞麦除极短的发芽期间外,营养生长和生殖生长是同时并进,因而不易区分其生育阶段。但从主茎顶端的生育长相来看,可分成以下四个生育阶段。首 In recent years, when paddy fields were dry in Japan, buckwheat was mostly included in the crop rotation system. This has become the main direction of buckwheat cultivation. However, it is not easy to achieve long-term stable yield. Dry buckwheat water change, the key to success is the prevention and treatment of wet damage. Yield of buckwheat is low, only about 100 kilograms per 10 hectares. The reason is: Buckwheat in addition to a very short period of germination, vegetative and reproductive growth is at the same time, it is not easy to distinguish the stage of its birth. However, from the top of the main stem growth phase of view, can be divided into the following four stages of fertility. first
