钛肥是保定钛肥厂1990年生产的一种新产品,商品名称“泰宝”。据报道,钛的增产机理主要是提高了作物的生理活性,光合作用强度增加6.6—85.8％,叶绿素含量增加9.1—21.7％,氮,磷肥利用率分别提高6.6—13.7％和29.0％。在各种作物试用平均增产10.1±0.9％,增产机率达75％左右。其中苜蓿、沙打旺等增产干草11.2—35.3％,小麦平均增产5.8- Titanium is a new product manufactured in 1990 by Baoding Titanium Fertilizer Plant under the trade name of “Tai Bao.” It is reported that the mechanism of increasing yield of titanium is mainly to increase the physiological activity of crops. The photosynthesis intensity increases by 6.6-85.8%, the chlorophyll content increases by 9.1-21.7%, and the utilization rates of nitrogen and phosphate increase by 6.6-13.7% and 29.0% respectively. Trial production in a variety of crops on average increase of 10.1 ± 0.9%, yield increase rate of about 75%. Among them, the yield of hay increased 11.2-35.3% for alfalfa, Astragalus mongholicus, and wheat increased 5.8-
