一、概况 马铃薯在我区有很久的栽培历史,但由于栽培不善、种性退化、产量不高、群众都不愿意种了,因而市场上马铃薯供不应求。每年要从远处调运,浪费大量的人力、财力还满足不了需要。为解决马铃薯种性退化问题,也走了不少弯路。从北种南调,进而采用推迟播种、嫩芽晚栽,二季作等方法。虽有些增产效果,但退化仍是严重的。近来利用马铃薯实生小籽、有性繁殖后、才获得了种性强的种薯,生产有了大幅度的增长。推动了地区马铃薯生产的发展。从各个试点验收一分地产量看,当代小籽5月份种的、亩产高达2650公斤、单株高产8.5公斤、单块大薯重960克。6月中旬麦茬地复种的,亩产
First, an overview of potatoes in our region has a long history of cultivation, but due to poor cultivation, degenerative species, yield is not high, the masses are reluctant to grow, so the market demand for potatoes. Every year to be transported from afar, wasting a lot of manpower, financial resources also can not meet the needs. In order to solve the problem of potato degeneration, but also take a lot of detours. From the north of the south tune, and then adopt delayed planting, planting late buds, seasons and other methods. Although some increase yield effect, but the degradation is still serious. Recently the use of potato seedlings, after sexual reproduction, access to species of strong seed, production has risen dramatically. Promote the development of potato production in the region. From each pilot to check the yield of a point of view, the current small seed May species, up to 2650 kilograms per mu, yield 8.5 kilograms per plant, single large potato weight 960 grams. Mid-June stubble crop, the mu yield
