A kind of shaping and pruning method of facility jujube tree

Abstract

The invention discloses a method for shaping and pruning jujube trees in facilities, which comprises the following steps: 1) fixed stem after planting; 2) shaping and pruning in the year of planting; 3) shaping and pruning in the second year of planting; 4) in the third year of planting And the plastic pruning of jujube tree in the fruiting period; the present invention selects and stays the first main branch jujube head at the top of the jujube tree in the fruiting period by applying the novel plastic pruning method of the jujube tree in the facility, so that it is perpendicular to the row of jujube tree planting in one direction Extend the growth horizontally, take advantage of its top advantage, control the sprouting and growth of the remaining jujube heads, and take into account the dual effects of jujube tree growth and fruiting, which can greatly reduce the workload of jujube tree topping and bud wiping during the growth period, and reduce labor intensity and labor At the same time, it can increase the growth of jujube branches and leaves, improve the utilization rate of light energy, ensure the high yield of jujube year after year, increase the commercial fruit rate, and promote the development of jujube industry in facilities.

Description

technical field

[0001] The invention relates to the field of jujube tree planting, in particular to a method for shaping and pruning jujube trees in facilities. Background technique

[0002] Jujube is a unique economic tree species in my country. It has a long history of cultivation. The planting area of ​​jujube in the country has reached 30 million mu. It has become one of the leading industries in my country's agriculture and has made great contributions to ecological construction and farmers' income. With the sharp increase in domestic jujube cultivation area and output and the situation of oversupply, coupled with the impact of climate change, regional precipitation has increased significantly, and the red jujube industry has undergone historic changes, forming production, quality, price, The overall decline in benefits has directly affected the production enthusiasm of the majority of jujube farmers, seriously threatening and hindering the sustainable development of th...

[0024] The shaping pruning method of facility jujube tree of the present invention, comprises the following steps:

[0025] 1) After the jujube tree is planted in the facility, set the trunk in time, leave 4 sections above the required trunk height as a plastic belt, cut off the top tip to fix the trunk, the height is 60cm, cut off the first secondary branch under the notch at the top of the trunk, and use the The main buds are pumped to give birth to the central leading stem, and 2 secondary branches are selected at intervals below it, and 1 node is re-cut to cultivate the main branch.

[0026] 2) Plastic pruning in the year of planting, and pruning during the growth period, except for the central leading trunk, erase the unsuitable angle and redundant new shoots, and the remaining developing branches can be properly opened at an appropriate angle and direction to cultivate the first layer of main branches.

[0039] The shaping pruning method of facility jujube tree of the present invention, comprises the following steps:

[0040] 1) After the jujube tree is planted in the facility, it is fixed in time, and 5 sections are reserved from the required trunk height as a plastic belt, and the top tip is cut off to fix the trunk, preferably at a height of 80 cm. The main buds on the main trunk are drawn from the central leading trunk, and 2 secondary branches are selected at intervals below, and 2 nodes are reserved to re-cut and cultivate the main branches.
