每年3～4月份黄姜萌芽出土(2年生黄姜3月中旬,1年生黄姜4月中旬),刚出土的幼苗植株弱小、生长缓慢,而此时杂草生长旺盛,与姜苗争水、争肥、争光,若除草不及时,此期最易形成草荒,影响贵姜块茎产量和质量,严重时可造成毁灭性损失。由于黄姜种植密度大,茎叶细弱又匍匐地面,人工除草易伤茎蔓,且费工费时,因此及时、科学
From April to April each year ginger unearthed (2-year-old turmeric in mid-March, 1-year-old turmeric in mid-April), just unearthed seedlings plant small, slow growth, and at this time the weeds grow vigorously, competing with ginger seedlings, fight fertilizer , Win glory, if the weeding is not timely, the most likely to form a grassland during this period, affecting the yield and quality of ginger tuber, in severe cases can cause destructive losses. Due to the high planting density of turmeric, stems and leaves are thin and creeping on the ground, artificial weed easily hurt the vine, and time-consuming work, so timely and scientific
