2000年起笔者在鄞州区鄞江镇金陆村进行连续四年的地膜、小拱棚、大棚三层套用的马铃薯超早熟栽培试验,取得了较好的效益。平均亩(1亩=667平方米,下同)产量在1500千克以上,产值4500余元。现将该栽培技术介绍如下。1.择地配茬,选用良种种植地块选择地势高、排水方便、土质肥的冬闲地和冬耕水稻田,宜实行马铃薯与水稻轮作,减轻病、虫危害。种马铃薯的田要在晚稻收割后,立即进行翻耕,以促进土壤分化,并注意开好排水沟。我们在金陆村选用的品种是比较耐寒、薯块大、薯形佳、外观光滑、黄皮白心、丰产性好的优质品种"东
Since 2000, the author has carried out ultra-precooked cultivation experiments of potato with three layers of mulching, small shed, and greenhouse for four consecutive years in Jinlu Village, Yinjiang Town, Yinzhou District, and achieved good benefits. The average mu (1 mu = 667 square meters, the same below) production in more than 1500 kg, the output value of 4,500 yuan. Now the cultivation techniques are as follows. 1. Optional stubble, the selection of high-quality planting plots to choose high-lying, easy drainage, soil fertility winter fallow paddy fields and winter farming, should be implemented potato and rice rotation, reduce disease, insect damage. Potato fields should be plowed immediately after the harvest of late rice to promote soil differentiation and pay attention to open ditches. The varieties we choose in Jinlucun are the high-quality varieties that are hardy, big tuber, good potato shape, smooth appearance, yellow white heart and high yield and good quality
