Qidong crisp jujube has the excellent characteristics of high yield, excellent quality, more than one year ripening, good resistance, strong adaptability, storage resistance and easy processing.

1. high yield: planting in the same year, bearing fruit in the same year, putting into production in the second year, and high yield in three or four years. According to the actual measurement by authoritative experts, the maximum yield of five-year-old trees is 42 kg, and the yield per mu is 1776 kg.

2. Excellent quality: the fruit is obovate with bright and gorgeous appearance. The meat is small and the edible rate is 97. 1%. The soluble solid content is about 40%, the texture is crisp, the juice is rich and the residue is rich, the sweetness is rich and the aftertaste is endless.

3. More than one year of ripening: more than one year of ripening, no big or small year phenomenon, and three batches of fruit can be produced every year. The first batch of fruit+head ripens early, and the output accounts for 30-70% of the total output. The second batch of fruits is even in size and better in quality than the first batch, and the output accounts for 20-60% of the total output. The third batch of fruits is smaller, but the quality is the best, and the output accounts for 10-20% of the total output.
