The invention discloses an elongated pinecone apple tree form and a trimming method thereof; the integral tree form is in an elongated pinecone shape; the tree is 3.5-4.5m in height when approaching a full bearing period, and has 25-30 main branches; the tree is 2.8-3m after lowering the cap, the main trunk is 1.0-1.5 m in height, the tree has 18-22 main branches, a main branch opening angle is 110-130 degrees, the main branch is 50-70cm in length on the upper portion of the crown, and 110-130cm on the lower portion of the crown; the spacing between the main branches is 10-20cm; the main branches are arranged in a spiral manner around the main trunk; the branch-trunk ratio is 1:3-6; the branch group-main branch ratio is 1:5-7. The tree form is small on top and big in bottom, tidy and standard, strong in main trunk, strong in wind-resistance, ventilating and light transmission, suitable for close planting, and is a high yield, stable yield, high-quality and high efficiency tree form; the trimming method complies with the trend that tree body frame decreases and trimming is simplified; the method is easy to handle, and good for promotion in wind-line close planting apple gardens.
