Cultivation of Golden Jujube Persimmon

I. characteristic characteristics

Golden jujube persimmon, also known as string persimmon, persimmon jujube, its fruit mature golden yellow, the shape is very similar to jujube, hence the name golden jujube persimmon. Golden jujube persimmon seedless, dried sweet crisp tender, mellow flavor.

The tree is 10 meters high and the young tree grows vigorously, especially the 4 buds at the top of 3mur. it can sprout new shoots three times a year, and the growth slows down gradually with the increase of tree age, only one branch a year; the root system is developed, the main root is distributed deeply, the lateral root is widely distributed, the fine root is many, the root hair is long, so the golden jujube persimmon is drought resistant and barren tolerant. Its flowering is later than that of other persimmon varieties, the florescence is as long as 10 seconds and 15 days, the flower bud differentiation begins one month after flowering, and the fruit increases rapidly after flowering. The fruit is green at the beginning and golden when it is ripe. The fruit expands 2 months after anthesis, and the fruit is colored to mature in October, and there is an obvious increasing trend at this time.

Golden jujube persimmons like to be warm, and can be grown in areas with an average annual temperature of 11 ℃ 20 min.

2. Cultivation techniques

1. Planting. Golden jujube persimmon can be planted at the foot of the field where the soil layer is relatively deep. Because of its temperature and humidity tolerance, the garden should be built on a mountain gentle slope with sufficient light. The planting density is generally 6 mi 8 m, plant spacing 4 mi 5 m, and planting after digging big holes and applying sufficient base fertilizer.

two。 Plastic surgery and trimming. Generally adopt trunk thinning layer shaping, because the golden jujube persimmon branch is soft, the result is large, the outer branch is easy to droop, adopt the trunk thinning layer shape, the fixed stem height is generally 1ml 1.5 meters, the mountain area can be appropriately lower. Intensive orchards can be shaped by natural happy shape or natural round head shape to facilitate early fruiting and high yield.

The pruning of golden jujube persimmon is mainly pruned in winter, which is generally strong and weak. attention should be paid to the cultivation and renewal of fruiting branches to ensure a certain proportion of fruiting branches and vegetative branches to prevent the phenomenon of big and small years. Young trees should be thinned less and cut more to increase the number of fruiting branches, and coring and other methods can be used to promote secondary branches to form fruiting branches.

3. Fertilizer and water management. In order to improve the quality of persimmon, organic fertilizer should be the main fertilizer, combined with chemical fertilizer, young trees can be fertilized with thin chemical fertilizer. Base fertilizer is generally applied in October and early May, and fertilizer is applied from August to September to promote fruit expansion. Because the young trees of golden jujube persimmon grow slowly, the young persimmon orchards can interplant legume crops.
