在农村经常碰到这样的问题:“准备每亩打一千斤小麦,应施多少肥料?”、“我施了10车土粪,100斤碳铵,80斤磷肥,又追了20斤尿素能打多少小麦?”为了回答这些问题,我们设计制作了小麦施肥计算器,其作用有三:①根据小麦单产推算小麦施肥量;②根据小麦施肥量推算小麦单产;③根据施肥量与小麦单产推算肥料效益,看施肥是否科学合理。 In rural areas often encounter such a problem: “to prepare a kilogram per acre of wheat hit, should be applied fertilizer?”, "I applied 10 car soil dung, 100 kg of ammonium bicarbonate, 80 kg of phosphate fertilizer, and chase 20 kg of urea In order to answer these questions, we have designed and implemented a wheat fertilization calculator, which has three functions: ① estimating wheat fertilization based on wheat yield; ② estimating wheat yield according to the amount of wheat fertilization; ③ estimating fertilization based on wheat yield Fertilizer benefits, see fertilization is scientific and reasonable.
