| Abstract: | Abstract: In order to realize the goal of fertilizer reduction and increasing efficicncy, the optimal amount of potassium for best economic benefit in main vegetables in Zhangye solar greenhouse was studied. The results showed that the potassium fertilizer amount for best economic efficiency of zucchini, cucumber, eggplant, tomato, pepper and celery were 128.60, 161.15, 40.30, 239.42, 258.91, 199.47 kg/hm2, respectively, and the theoretical yield were 78.38, 77.49, 58.02, 92.44, 65.02, 103.99 t/hm2, respectively. The order of profit change from big to small was tomato > celery > pepper > cucumber > zucchini > eggplant. |
