兴山县地处鄂西山区,地形复杂,高差悬殊,气候差异大,属温凉多雨气候带,有利于发展洋芋生产, 1985年洋芋播种面积占全县粮食作物播种面积的21.59%,占夏粮面积的44.16%,占夏粮总产的48.1%。最高年景的1979年,洋芋播种面积达到9.26万亩,占全县粮食作物面积的33.73%,总产达到991万公斤,面积比50年代初期增长了2.97倍,总产增长了3.55倍。但由于品种混杂退化严重、栽培粗放及施肥水平等等原因,单产仍然较低。为了进一步发展我县洋芋生产,根据多年生产调查和科学实验的结果,提出如下措施。 1、改革耕作制度,实行苞芋、麦芋双(行)套双(行)的种植规格 我县洋芋生产在半高山、高山地区大多是苞芋、麦芋套种,但种植不规格、宽大行种植,一丈远一行洋芋,亩株数稀。据我县农牧局、农科所在半高山、高山调查,苞芋套种的带距为3.5米的宽大行只种一行洋芋,亩株数仅1200多株。1986年农科所在棒子乡调查苞芋套种田,带距3.4米,单行洋芋,
Xingshan County is located in the western mountainous area of Hubei Province, with complex terrain, high altitude disparity, large climatic differences, and a warm and rainy rainy climate zone, which is conducive to the development of potato production. In 1985, potato planting accounted for 21.59% of the sown area of grain crops in the county, accounting for 44.16% of the summer grain area accounted for 48.1% of the total summer grain output. The highest year of 1979, potato planting area of 92,600 mu, accounting for 33.73% of the county’s food crop area, the total output reached 9.91 million kilograms, an area of 2.97 times the early 1950s, an increase of 3.55 times the total output. However, due to the serious degradation of hybrids, extensive cultivation and fertilization levels and other reasons, yields are still low. In order to further develop potato production in our county, according to the results of many years of production survey and scientific experiments, the following measures are proposed. 1, the reform of farming system, the implementation of taro, wheat taro double (line) sets of double (line) planting specifications in our county potato production in the semi-alpine, alpine mostly of taro, wheat taro intercropping, but planting irregularities, wide line Growing, a long line of potato, acres of rare plants. According to our county agriculture and animal husbandry bureau, the semi-alpine and alpine where the agricultural sciences are located are only one line of potato with a distance of 3.5 meters and the number of mu is more than 1,200. Gynecology in 1986 where the survey of corn seedlings taro sets of farming, with a distance of 3.4 meters, a single line of potato,
