榨菜采用播种器直播具有省工、节本、减轻病毒病发生等优点。据试验示范,直播每亩(1亩=667平方米,下同)可省去移栽用工6工左右,计减少用工费150元并可少施一次追肥。直播还可增强榨菜的抗病能力,减轻病毒病发生率15%以上。直播技术如下。1.播前准备(1)翻耕趁适宜墒情时翻耕、整地,土块要细。如土块大,易导致播种器轮子行走不稳,把种子折向一边,落种不均
Mustard broadcast live seeder with a province, section, reduce the occurrence of viral diseases and so on. According to experimental demonstration, live mu (1 mu = 667 square meters, the same below) can save about 6 workers transplanting, reduce the labor cost of 150 yuan and can be applied less fertilizer. Live can also enhance the resistance of tuber mustard, reducing the incidence of viral diseases more than 15%. Live technology is as follows. 1. Preparing for sowing (1) Plowing tillage while tillage, soil preparation, soil to be fine while soil moisture is suitable. Such as clods, easily lead to seeder wheels walking unsteadily, the seeds off to one side, uneven species
