马铃薯是冬季粮食兼用的高产作物,一般产量30—37.5吨/公顷,高的可达52.5吨/公顷以上,且省工省本,经济效益好,适应性强,容易栽培。我市海澄镇是马铃薯高产栽培区,产量达45吨/公顷。其高产栽培技术是: 一、选好土地 土地应选择前作未种马铃薯和茄科作物。马铃薯中后期地下部分生长快,要求深厚疏松的土层,故应选择有灌溉条件、土层深厚的田块种植,同时,前作晚稻收割后要及时用旋耕机进行翻犁破碎,整地要求细、匀、松,创造深厚、疏松的土
Potato is a high-yield crop with both winter grain and cereals. Its output is 30-37.5 tons / hectare in average and up to 52.5 tons / hectare in height. It also has the advantages of low cost, high economic efficiency and adaptability. It is easy to grow. Haicheng Town, our city is a high-yielding potato cultivation area with a yield of 45 tons / ha. Its high-yielding cultivation techniques are: First, the selection of land should be selected before the land for potato and solanaceous crops. Potato in the late part of the rapid growth of underground parts, requiring deep loose soil, it should choose the irrigation conditions, deep soil plots planted at the same time, after the late rice harvesting in time with rotary tumbler plow broken, fine preparation requirements , Even, loose, to create deep, loose soil
