目标产量又叫计划产量。土壤肥力是影响产量高低的基础,在相同环境条件下,土壤肥力水平高,产量水平也相应较高,反之则低。我省配方施肥技术方案中第一类方法就是目标产量法(包括养分平衡法和地力差减法),这两种方法中,目标产量是计算施肥量的一个重要参数,估计过高或过低直接影响到施肥量的准确性和配方施肥的实际应用效果。
The target output is also called planned output. Soil fertility is the basis of high and low yield. Under the same environmental conditions, the soil fertility level is high, the yield level is correspondingly high, and vice versa. The first method of formula fertilization program in our province is the target yield method (including the nutrient balance method and the soil subsidence method), the two methods, the target yield is an important parameter to calculate the amount of fertilizer, estimated to be too high or too low direct Affect the accuracy of fertilizer amount and the practical application effect of formula fertilization.
