旱稻在泗县南部地区栽培年代甚久。它在生育前期能耐春旱,而生育中后期又适应夏涝,只要水深不没顶,就能得到正常的收成。泗县旱稻栽培面积一般每年均在四万亩以上,土地較好地区一般亩产三百斤以上,高的可达六、七百斤;土地較瘦地区一般亩产一百五十斤左右。根据调查,現将提高旱稻产量的几个关键措施介紹如下,以供参考。一、加强苗期管理。旱稻苗期生长緩慢,最怕草欺,如果管理不好,就会严重減产。我县群众在播种后七天左右,尚未出苗前用短齿耙耙一遍,这时杂草幼嫩,絕大部分都可消灭,并能耙去过深的复土,疏松表土,保墒防旱,有利出苗。当苗高三、四寸时,杂草又长起来,則用长齿耙在中午或下午
Upland rice cultivated in the southern region of Si County for a long time. It is resistant to spring drought early in the reproductive years, but also adapt to the summer floods in the late reproductive, as long as the water depth is not top, you can get the normal harvest. Si County rice cultivation area is generally more than 40,000 mu each year, the land area generally better than three hundred kilograms per mu, up to six or seven kilograms; the land area is generally less than 150 kilos per mu yield. According to the survey, several key measures to improve the yield of Upland are presented below for reference. First, to strengthen seedling management. Arid rice growth is slow, most afraid grass bullied, if not managed, it will severely reduce production. The masses in our county about seven days after sowing, not before emergence with short rake harrow again, when young weeds, most of them can be eliminated, and can be harrowed too deep soil, loose topsoil, soil moisture drought, Benefit sprout. When the seedling height three or four inches, the weeds grow up, then use long teeth rake at noon or afternoon
