环县地处陇东黄土高原丘陵沟壑区,居陕甘宁交界处。海拔1136～2089米,平均气温6.7～9.2℃,年日照时数2596.2～2766.4小时,年降雨量350～500毫米,无霜期123～151天。糜子是环县旱地主要农作物之一,常年面积为20万亩以上,占粮食作物播种面积的20～30％。正常年份山旱地亩产75～110公斤,旱源地亩产200～250公斤,为了探索旱地糜子高产栽培技术,1988年以来,通过多点调查、试验、示范,认识到糜子有耐旱耐瘠的特性,在干旱多灾的旱地大有发展前途。现将其高产栽培技术介绍如下: (一)播前准备目前栽培糜子,还存在耕作粗放、施肥不足、种子混杂、产量不稳等问题,要提高糜子的产量,要抓好以下几点:1.合理轮作。糜子对土壤和前茬要求并不严格。但以土层深厚,土质肥沃,通气良好的地块有利于高产。
Central County is located in Longdong Loess Plateau hilly areas, Habitat at the junction of Shaanxi and Gansu. 1136 ~ 2089 meters above sea level, the average temperature of 6.7 ~ 9.2 ℃, the annual sunshine hours 2596.2 ~ 2766.4 hours, annual rainfall 350 ~ 500 mm, frost-free period 123 ~ 151 days. Millet is one of the main crops in Huanxian dry land, perennial area of 200,000 mu or more, accounting for 20 to 30% of sown area of food crops. In normal years, mountain dry land yields 75-110 kg per mu and 200-250 kg per mu in dry land. In order to explore high-yielding cultivation techniques for dryland millet, since 1988, through multi-point investigation, experiment and demonstration, it has been realized that millet has drought- The characteristics of the dry and drought-prone dry land promising. Now the high-yielding cultivation techniques are introduced as follows: (A) Preparing for planting At present, the cultivation of millet, there are still extensive cultivation, inadequate fertilization, mixed seeds, yield instability and other issues, to improve the yield of millet, to grasp the following points: 1 Reasonable rotation. Millet on the soil and the former crop requirements are not strict. However, with deep soil, fertile soil, well-ventilated land is conducive to high yield.
