Ⅰ. Test Site: Cherry Base of Greenhouse in Fuping, Shaanxi Province, China.
Field Area: 53,336 square meters, 44 seats, spacing 3 x 4 (50 trees per greenhouse), 8-year-old trees (no small or big trees).
The original yield of the base was 50 kg per tree, and the total yield of the base was 110,000 kg.
Ⅱ. Experimental Period and Methods
Experimental period: August 2020 – March 2021.
All cherry trees at the base (including Tieton, Sameton, and other varieties) were treated with Da An Marine Minerals three times.
1st treatment: Foliar spray and root application in autumn.
2nd treatment: One foliar spray during the young fruit stage.

Ⅳ. Market Sales Situation
The Tieton variety was marketed earlier than other bases in Shanxi and quickly spread in Fuping and even the Xi’an market due to its superior quality. Local fresh food supermarkets, fruit supermarkets, and other businesses came to place orders. The busy scene of picking and boxing at the base lasted from morning to night. At the same time, the highest-quality cherries were also made into luxury gift boxes and were charged by the piece.
