金衙地区是浙江省重要的商品粮基地之一。近些年来农村产业结构和劳力结构起了一些变化,农村商品经挤日趋繁荣。但因金衢盆地地形复杂,土类众多,肥力差异大,坡地及山沿田易遭伏秋旱,而低丘垄田及山垄困易受侧渗水影响,往往质地粘重,土体闭塞,通透性差,渍害严重;或因土劳负担过重,熟制单一,耕作粗放,生产技术水平低;或因重工轻农,重经轻粮,劳力转移过多,乃至减少了农业物质投入,种粮积极性欠高。凡此种种导致了较大面积的中低产田(地),粮食年亩产通常低子平均水平二三成,甚至在500公斤以下。如何使中低田(地)粮食跃上去,实现大面积平衡增产,已是当务之急的研究课题。
Jinya area is one of the important commodity grain bases in Zhejiang Province. In recent years, some changes have taken place in the industrial structure and labor structure in rural areas, and the rural commodity economy has been increasingly prospered. However, due to the complex terrain, numerous soil types and large differences in fertility, the Jinqu basin is prone to fall in autumn and autumn, while the hilly ridge and mountain ridge are susceptible to lateral seepage, often with heavy texture and soil blockage , Poor permeability, serious stain damage; or because the soil overburdened, cooked a single, extensive farming, low level of production technology; or due to heavy industry light agriculture, heavy light food, labor transfer too much, and even reduce the agricultural material Input, lack of enthusiasm for growing grain. All these middle and low-yield fields (or land), which led to a larger area, usually produce 20-30% of the low-level average grain yield per year, even below 500 kg. How to make low-lying fields (ground) food to go up and achieve large-scale and balanced production has become a top priority research topic.
