土壤肥力的高低,对作物产质量的关系极大,故世界各国对土壤肥力变化的研究给于极大的关注,并提出了解决土壤肥力的许多办法,使作物产质量得到了很大的提高。目前,我国在实现农业生产现代化的进程中,科学工作者正在从各个角度研究提高作物单位面积产质最的规律,很多研究资料证明,在品种性能与气候条件既定的情况下,作物产质量决定于土壤肥力以及对作物养料的供应情况,甜莱是黑龙江省的主要经济作物,要求在2000年有双倍的增长,这就必须采取多方面的努力才能达到这一目标。而土壤肥力是甜菜产质量的基础,为此就黑龙江省土壤肥力变化特点及其与甜菜产质量的关系谈几点个人意见。
The level of soil fertility has a great relationship with crop yield and quality. Therefore, great attention has been paid to the research on the changes of soil fertility in various countries of the world, and many solutions to soil fertility have been put forward, which have greatly improved the crop yield and quality . At present, in the process of realizing the modernization of agricultural production in our country, scientists are studying the law of maximizing the yield per unit area of crops from all angles. Many research data prove that under the conditions of variety performance and climatic conditions, In terms of soil fertility and the supply of crop nutrients, the sweet rice is the major cash crop in Heilongjiang Province and requires double growth in 2000, which requires many efforts to achieve this goal. Soil fertility is the basis of sugarbeet yield and quality. Therefore, I have some personal opinions on the characteristics of soil fertility and its relationship with the quality and yield of sugar beet in Heilongjiang Province.
