影响甜菜产量的主要因素是田间保苗率.据调查,一般甜菜缺苗率38%左右,高的达55%,给甜菜生产造成极大损失,因此,采取措施保全苗是提高甜菜产量的关键环节.1.整地增行:甜菜是需水需肥较多的块根作物,要种在耕层深厚,土壤肥沃、通透性好的地块上.要在深翻耙压的基础上细致整地,多次进行耙压保墒,做到地平土碎,表土疏松,墒情良好,以利种子萌发出苗.
The main factor affecting the yield of sugar beet is the seedling protection rate in the field.According to the survey, about 38% of the sugarbeet lacking rate is generally about 55%, causing a great loss to beet production, therefore, taking measures to preserve the seedling is the key to improving sugar beet yield .1. Land preparation line: Beet is water and fertilizer needs more root crops, to be planted in the deep plow, fertile soil, good permeability of the land.To the deep flip rake pressure on the basis of meticulous soil preparation, Repeatedly rake pressure soil moisture, so that the ground crushed, loose surface soil, good moisture content, to facilitate seed germination.
