春马铃薯地膜覆盖栽培,是近年来发展的一项新的栽培技术。它具有播种早、出苗齐、结薯早、产量高、上市早、效益好等特点。据调查,春马铃薯地膜覆盖栽培比常规露地栽培可提早15天左右上市,每667米~2增产350公斤,增收800元。春马铃薯地膜覆盖栽培,主要应抓好以下技术环节: 1.选用良种。地膜覆盖栽培的春马铃薯品种应选用早熟高产、生长快、结薯早、生育期短、抗病力强的良种。据试种,“东农303”、“克新4号”表现较好,可以选用。 2.适时播种。春马铃薯以昼夜平均气温17～21℃最有利于块茎的形成和
Spring potato mulching cultivation is a new cultivation technique developed in recent years. It has early sowing, emergence of Qi, early tuber, high yield, early market, good benefits and so on. According to the survey, spring potato mulching cultivation than the conventional open-field cultivation can be listed about 15 days earlier, an increase of 350 kg per 667 m ~ 2, an increase of 800 yuan. Spring potato film mulching cultivation, mainly should grasp the following technical aspects: 1. Selection of elite. Spring potato varieties covered by plastic film should be used for early maturity and high yield, fast growth, early tuberization, short growth period and strong resistance to disease. According to test species, “Dongnong 303”, “Kexin 4” performed better, you can choose. 2. timely sowing. The average daily temperature of spring potato 17 ~ 21 ℃ most conducive to the formation of tubers and
