Problems solved by technology

The cylindrical tree shape is not layered, and the distribution of fruiting branches is not reasonable enough. Although the yield is relatively high, the weight of a single fruit is small, and the high-quality fruit rate is low.

Embodiment 1

[0014] In 2012, a test field was planted in the Yanhu District of Yuncheng. The shape of the winter jujube tree in the test field adopts the following structure: use spiral layered misplaced pruning, leave 6-8 fruiting branches with the same growth, and retract the fruiting branches, leaving 5 jujube strands for each branch. -7 plants, 2-3 jujube hangers for each jujube stock, the plant height is set at 2-2.5m, the planting density is: the plant spacing is 0.7m, the row spacing is 1.2m, and 796 plants are planted per mu. In 2014, the fresh winter jujube fruit yield was 840 kg per mu; in 2015, the experimental field yielded 2080 kg fresh winter jujube fruit per mu, and the high-quality fruit weighing more than 20g reached 1765 kg. In 2016, the yield per mu of winter jujube fresh fruit in the experimental field was 2,240 kg, and the high-quality fruit reached 1,880 kg.

Embodiment 2

[0016] The experimental field was planted in Linyi, Yuncheng in 2012. The tree shape of the winter jujube tree in the experimental field adopts the following structure: use spiral layered misplaced pruning, leave 6-8 branches with the same growth, and retract the fruiting branches, leaving 5-7 jujube strands for each branch 2-3 jujube hangers for each jujube stock, the plant height is set at 2-2.5m, the planting density is: the plant spacing is 0.8m, the row spacing is 1m, and 830 plants are planted per mu. In 2014, the yield of winter jujube fresh fruit per mu was 980 kg; in 2015, the yield of winter jujube fresh fruit per mu in the experimental field was 2160 kg, and the high-quality fruit weighing more than 20g reached 1690 kg. In 2016, the yield per mu of winter jujube fresh fruit in the experimental field was 2320 kg, and the high-quality fruit reached 1920 kg.

Abstract

The invention discloses a dwarfing and dense planting high-yield tree shape for facility dates and belongs to the technical field of high-yield tree shapes for facility dates. The invention aims at providing a tree shape for the facility dates with early harvesting, stable yield, high excellent-fruit rate and suitability for high-density planting. The invention adopts the technical scheme that the plant height is set to 2-2.5m, the independent truck is spirally layered, each layer has a fruiting branch, 6-8 fruiting branches are remained on each plant, 5-7 date spurs are remained on each fruiting branch, 2-3 date shoots are remained on each spur, and wooden date shoots are specially cultured; the crown projection of the tree shape is controlled to 0.6-0.7m<2>; the planting density of the tree shape for the facility dates is 550-800 plants / mu; 6-8 fruiting branches are pruned in a spirally-layering and staggering manner, and the growing conditions are basically consistent. The dwarfing and dense planting high-yield tree shape disclosed by the invention is applicable to dense planting of the facility dates and is obvious in effect.

Description

technical field [0001] The invention specifically relates to a high-yielding jujube tree shape for facilities. Background technique [0002] The main cultivars of facility jujubes are Dongzao, Mayazao, Zaocuiwang, Qiyuexian, Gongzao, Fucuihong, Fucuimi, Zaosuya, Zaocriwang, etc. Among them, Dongzao has the largest cultivation area. It is an excellent late-maturing and fresh-eating variety. It is also recognized as the best-quality fresh-eating jujube variety. The average single fruit weight is 17.5g, and the maximum single fruit weight can reach 25g. It is shaped like an apple and has a "small apple" known as. The peel is reddish red and bright, the skin is thin and the meat is crispy, sweet and fragrant, rich in nutrition, and the edible rate reaches 95%. Compared with other fruits, jujube is also rich in vitamin A, vitamin E, potassium, sodium, iron, copper and other trace elements. The content of vitamin C is 70 times that of apples and 140 times that of pears. It is k...
