早熟马铃薯在中原地区以春季为主要栽培季节,适宜生长期仅60～70天。根据其生育特点,结合当前的生产实践,总结出早熟马铃薯“三早三巧”高产高效栽培技术。 1 三早 1.1 选用早熟品种。实践证明,选用生育期70天以内(出苗至收获)的早熟、高产、脱毒优种,是实现早熟马铃薯高产稳产的关键。当前的理想品种主要有荷兰7号、东农303、郑薯6号、鲁薯1号、克新4号等。 1.2 提早催芽。播前利用阳畦进行提早催芽,可使
Premature potato in the Central Plains in spring as the main cultivation season, suitable growth period of only 60 to 70 days. According to its reproductive characteristics, combined with the current production practices, summed up the precocious potato “three early three clever” high yield and efficient cultivation techniques. 1 three early 1.1 Selection of precocious varieties. Practice has proved that the selection of the growth period within 70 days (emergence to harvest) of early maturity, high yield, detoxification superior, is the key to achieving high yield of precocious potato. The current ideal varieties are mainly Holland 7, Dongnong 303, Zhengshu 6, Lushu 1, Kexin 4 and so on. 1.2 premature germination. Pre-sowing Yang Yang pre-germination can be used
