Field management technology of green jujube

The management work after planting green jujube is more complicated, because green jujube is a fruit growing in the tropics, and it is prone to diseases under tropical high temperature and humidity, especially if the humidity is high, so watering must be well controlled, and nutrition can not be lacked. Maintain a good tree potential in order to resist diseases and insect pests. In the critical period of blossom and fruit, special management is needed.

1. Planting management

It is best to plant from January to February before the trees sprout. Fertilization should be mixed with the subsoil and backfilled, and then covered with a layer of topsoil before planting, the root system does not touch the fertilizer. Planting should be sparse but not dense, fertile land can have a row spacing of 5 meters and a plant spacing of 3.5 meters; barren land can have a row spacing of 4 meters and a plant spacing of 3 meters.

2. Stereotyped pruning

The main purpose of the young tree is to establish the tree shape with fixed trunk and leave branches, and cultivate the fruiting branch group. Set the stem 40cm off the ground, induce lateral branches, stagger the remaining branches, leave 4 strong branches as the trunk, and sparse the others. Then gradually increase the side branches and leave branches, thinning out the excess. Adult trees should be renewed with strong shoots in summer and old branches cut short in winter. In the future, spring and autumn shoots can be kept.

3. Pruning and framing

The branches are easy to sag after bearing fruit, and it is even easier to aggravate the sagging after rain, and sometimes the branches will break by themselves. So you can set up a frame before the fruit, give the plant a support, maintain the shape of the tree, with wood, bamboo, wire and other fence frame, the height is 2/3 of the height of the spider.

4. Control of fertilizer and water

When base fertilizer is applied in spring, 40 jin of fertilizer is applied to a young tree, 60 jin of fertilizer is applied to an adult tree without fruit, and 100 jin of farm manure is applied to the fruiting tree. Then it is necessary to apply fertilizer twice before flowering, one plant at a time, one jin of compound fertilizer, one jin of compound fertilizer, one jin of nitrogen fertilizer, one jin of potash fertilizer, a total of about three times.

5. Increase the fruit setting rate.

In order to produce high-quality fruit, it is necessary to remove part of the fruit during flowering and concentrate on nutrition and fruit. as a result, you can gently shake the fruit tree in a month, drop part of the fruit, unstable fruit, and then remove some dense fruit, abnormal fruit. Small, diseased fruit, reduce consumption, bear large fruit.

The above is about the field management of green jujube after planting, all aspects should be taken into account, and then meticulous management. The above content as a reference, thank you for reading, continue to support.
