水肥是保证小麦正常生长,并夺取丰收的重要因子。河北省农科院驻南宫市南杜基点组,针对该区干旱缺水、土壤瘠薄、化肥相对充足的生产实际,经七年的试验研究,在小麦水肥运用方面有了新的突破,并提出小麦水肥运用新技术: 一、施肥技术。在小麦的施肥上,人们传统的观点和作法是依浇水条件好坏和浇水量的多少来确定施肥量。近几年的研究发现,小麦浇足底墒水、生长期间浇1—3水的条件下,肥效的高低并不取
Water and fertilizer is to ensure the normal growth of wheat, and capture an important factor in harvest. Hebei Academy of Agricultural Sciences in Nandong City South Dujiji point group, aiming at the actual production of drought and water shortage, infertile soil and adequate fertilizer in the area, after seven years of experimental research, there has been a new breakthrough in the application of wheat water and fertilizer, and put forward Wheat water and fertilizer use of new technologies: First, fertilization technology. In the wheat fertilization, people’s traditional view and practice is to determine the amount of fertilizer according to the quality of watering conditions and the amount of watering. In recent years, the study found that wheat pouring enough moisture at the end of the water, growth conditions, water 1-3, the level of fertilizer does not take
