采用优良小麦品种南大2419,是湖北小麦丰产综合栽培措施中重要环节之一。根据过去区域试验的结果,该品种有湖北六个小麦产区三年平均增产(比当地种)14—47%,在有些县里增产达一倍以上,这说明增产的效果是很显然的。该品种在湖北的种植面积达1300万亩以上,约占小麦总面积90%左右。由于其面积大,品种的增产对全省小麦总产量有极大的作用。因此在不断提高栽培技术的同时,也要重视巩固和提高良种的优良种性,以达到全面丰收的目的;假如忽视良种在增产中的一定作
Adopting the excellent wheat variety Nanda 2419 is one of the important links in the comprehensive cultivation of wheat in Hubei province. According to the results of the past regional experiments, the yield of the six wheat growing areas in Hubei Province has increased by 14-47% on an average over the three years (compared with the native species) and more than doubled in some counties, indicating that the effect of increasing yield is obvious. The cultivated area of the variety in Hubei reached more than 1300 mu, accounting for about 90% of the total area of wheat. Due to its large area, the increase of varieties has a great effect on the total output of wheat in the province. Therefore, while continuously improving cultivation techniques, we must also attach importance to consolidating and improving the fine varieties of elite so as to achieve the goal of full harvest. If neglect of the elite in increasing production
