Abstract

The invention discloses a novel technique for managing jujube trees after leaves falling. The novel technique is characterized in the following steps: adding and applying compost and watering, breaking up and planning a management belt, properly pruning, eliminating insect pests of jujube trees, and the like. The novel technique can help the jujube trees to live through winter safely, and can effectively suppress jujube shoots from growing too much and too lengthy. The novel technique reduces useless nutrients consumption, adjusts flow direction of nutrients, increases fruit setting rate of the jujube trees, increases quality of the jujube trees, and is suitable for managing the jujube trees after leaves falling in late autumn and early winter.

Description

A kind of management new technique after jujube tree fallen leaves

Technical field

The present invention relates to fruit-bearing forest field of planting, specifically the management new technique after a kind of jujube tree fallen leaves.

Background technology

To the management germinateed after jujube tree fallen leaves, it it is jujube tree basic management in a year. This time period management quality, on the coming year jujube growth, result impact greatly, some control measures be other in period institute irreplaceable.

Summary of the invention

The present invention solves the management technique problem after tradition jujube tree fallen leaves, invent the management new technique after a kind of jujube tree fallen leaves.

The present invention solves above-mentioned technical problem, the technical scheme taked, the management new technique after a kind of jujube tree fallen leaves, it is characterized in that and includes procedure below:

1, rich water is enriched. Jujube tree 1 year growth, result consumes substantial amounts of nutrient, it is necessary to supplement in time, after jujube tree is fallen leaves, fertilising before soil is freeze-up, fertilising can be spread fertilizer over the fields or ditch spread, and spreading fertilizer over the fields is that barnyard manure is uniformly spread under tree crown, then ploughing under in soil, ditch spread is divided into radial ditch spread and well shape ditch spread. Treelet should adopt radial ditch spread, and way is peripheral from trunk 20cm to tree crown, digs 6--8 bar width 20--40cm, deep 10--20cm, interior shallow outer narrow outer wide radial furrow deep, interior, is applied by barnyard manure and earthing. Bearing-age tree adopts groined type ditch spread, and under tree crown, the ditch of wide 30cm, deep 15--20cm is dug in direct motion, and ditch, from 30cm, applies barnyard manure, and earthing flattens. Next year, dressing furrow was from the direction excavation of vertical tree row, it should be noted that protect the thick root of more than diameter 0.5cm during trench digging. Dose should be determined according to yield, the big tree of General Result, and fresh Fructus Jujubae about 10--25kg is produced in strain, executes barnyard manure 75--100kg, separately adds calcium superphosphate 1.5--2.0kg. If spring basal dressing, part chemical nitrogen fertilizer can be mixed. Should watering in time after fertilising, irrigation quantity is as the criterion to irrigate.

2, plane management band is turned over. Turn over plane jujube tree management band can not only chesson, retain sleet, moreover it is possible to eliminate and survive the winter insect under tree. Plane is respectively turned over 1 time in Winter-Spring, turns over plane degree of depth 10--20cm.

3, proper pruning. Wipe out the branch very low without bearing capacity or bearing capacity, remove intersection branch, dense branch, overlapping branch and thin and delicate branch, in order to ventilation and penetrating light. Determine to cut to stay length to the branch of excessive growth its space size visual, space is big, the promising perennial branch of excessive growth, skeleton branch can be trained. All saw is except withered dead arm, sick branch, and saw kerf should cut branch place alive as far as possible, and saw kerf should be scabbled, and is coated with mixed paint, in order to avoid continuing dry and cracked rotting. To on skeleton branch the 1 of pumping, 2 years raw developmental branches, can cut according to space size and cut, stay 4--6 Secondary Branch, be trained the fruit-bearing shoot cluster of stalwartness. Should be bounced back 1/3--1/2 to old and feeble skeleton branch, and the diameter of retraction position clip is not to be exceeded 5cm, needs to reserve resting bud upwards or bearing basal shoot under clip; Should bounce back to dredge to old and feeble fruit-bearing shoot cluster comprehensively and cut; More complete branch group can be contracted and cut 1/2 or 1/3, inspire shoot. The tree that aging degree is serious, should stop first and support tree. During stopping first, renewal should be coordinated to prune, enrich the measures such as rich water, accelerate tree vigo(u)r and recover.

4, jujube tree insect pest is eliminated. By dry and cracked bark scraped clean before freeze-up, concentrate and burn or buried, eliminate worm source of surviving the winter. It is one of Major Pests In Jujube Forests that jujube tree ceroplastes floridensis (is commonly called as tree louse). Because Fructus Jujubae louse is that the female worm that is fertilized survives the winter on the raw branch of 1--2, so the opportune time in winter should be caught, brushes by branch, when turning over plane tree dish winter, notes that the worm pupa of surviving the winter picked up under tree in soil, worm cocoon disappear and ruin.

Technique effect

The solution have the advantages that, adopt technique scheme, safe overwintering purpose after jujube tree is fallen leaves can be realized, this mode is not only convenient for operation, and the coming year can effectively be suppressed the too much long growth of Fructus Jujubae head, reduce unhelpful nutrient consumption, regulate the flow direction of nutrition, improve the fruit-setting rate of jujube tree, improve jujube tree yield. .

Detailed description of the invention

1, rich water is enriched. Barnyard manure being uniformly spread under tree crown, then ploughs under in soil, ditch spread is divided into radial ditch spread and well shape ditch spread, should water in time after fertilising, and irrigation quantity is as the criterion to irrigate.

2, plane management band is turned over. Plane jujube tree management band is respectively turned over 1 time in Winter-Spring, turns over plane degree of depth 10--20cm.

3, proper pruning. Wiping out the branch very low without bearing capacity or bearing capacity, remove intersection branch, dense branch, overlapping branch and thin and delicate branch, all saw is except withered dead arm, sick branch, and saw kerf should cut branch place alive as far as possible, and saw kerf should be scabbled, and is coated with mixed paint, in order to avoid continuing dry and cracked rotting.

4, jujube tree insect pest is eliminated. By dry and cracked bark scraped clean before freeze-up, concentrating and burn or buried, eliminate worm source of surviving the winter, Fructus Jujubae louse is that the female worm that is fertilized survives the winter on the raw branch of 1--2, brushes by branch, when turning over plane tree dish winter, picks up the worm pupa of surviving the winter in the lower soil of tree, worm cocoon disappears and ruins.

Claims
