洋芋是我社冷凉山区主要旱地作物,正常年景播种面积5500—6000亩,占旱地粮食作物面积的四分之一左右。洋芋适应性广,生育期短,增产潜力大,发展洋芋生产是冷凉山区粮食大上快上,改善山区人民生活的一项重要措施,但是洋芋在生产上存在严重的种性退化,过去多从高寒山区调换种茁。当年调种,当年增产,连续种植,产量逐年下降,每年冬春两季都得花费很大的劳力,物力,财力调种,增加了群众负担,生产投资比其他作物增加,给生产上带来了很大的
Potato is our main dry land crops in the cold and cool mountainous areas of our company. The normal annual sown area is 5500-6000 mu, accounting for about one quarter of the dry land grain crops. The adaptability of potatoes is wide, the growth period is short, and the potential for yield increase is large. The development of potato production is an important measure to improve food quality in cold and cold mountainous areas and improve people’s life in mountainous areas. However, there are serious species degeneration in potato production in the past From the alpine mountain change Zhuo. In the current year of planting, when the yield was increased and continued to be cultivated in the current year, the output was declining year by year. Large amounts of labor, material and financial resources were invested in winter and spring seasons, increasing the masses’ burden, increasing the investment in production over other crops, and bringing production A lot of
