甘肃省甜菜产区主要分布在气候干燥的河西走郎,这里昼夜温差大、日照时间长、具有便利的灌溉条件,是我国种植甜菜的最适宜区。但近年来许多种植户重施氮肥,以获较高的根产量,造成氮、磷比例失调,使甜菜含糖下降,纯度降低,根产量也长期徘徊不前。鉴于上述,我们在各糖厂的通力配合下于1989年在河西地区进行了甜菜配方施肥试验,初步筛选出了适宜河西灌区甜菜栽培的4种配方,1990年对上述4种配方进行了小区比较试验,认为配方4号为最佳配方,并称其为甜菜专用肥。1991年又对4号配方与等养分肥料进行了比较试验;结果证明肥效相当。
The beet producing areas in Gansu are mainly distributed in the dry climate of Hexi, where there is a large temperature difference between day and night, long sunshine duration and convenient irrigation conditions. It is the most suitable area for planting beet in China. However, in recent years, many growers re-applied nitrogen fertilizer to obtain higher root yield, resulting in imbalance of nitrogen and phosphorus, sugar beet decreased, purity decreased, and root production also lingered for a long time. In view of the above, we sugarbeet formula fertilization experiments in Hexi region in 1989 with the full cooperation of the various sugar mills, initially screened four kinds of formula suitable beet cultivation in Hexi Irrigation Area, in 1990 compared the above four kinds of formula Test, that the formula No. 4 for the best formula, and said it beet special fertilizer. In 1991 and on the 4th formula and other nutrient fertilizers were compared; the results prove that the fertilizer efficiency.
