Abstract

The invention relates to a novel technology for transforming a low-yield pomegranate orchard. The technology is characterized in that through the steps of enhancing soil, water and fertilizer management, reasonably shaping and trimming trees, enhancing flower and fruit stage management, comprehensively controlling pests and diseases, and the like, a purpose of increasing pomegranate yield can be realized. The technology is suitable for transforming low-yield pomegranate orchards.

Description

A kind of new technology of low yield Pomegranate Garden transformation

Technical field

The present invention relates to fruit-bearing forest field of planting, specifically a kind of new technology of low yield Pomegranate Garden transformation.

Background technology

The part orchard worker early yield of unit are that covets in recent years, the seeding row spacing of planting is too small, and orchard Yu Mi appears in field planting after several years, ventilative printing opacity bad phenomenon, affect bud differentiation, tree crown is upright, skeleton branch angle too small, and apical dominance is strong, cause the strong up and weak down and strong outside and weak inside of tree crown, skeleton branch bottom brachyplast few and a little less than, be difficult to into coloredly, the pomegranate tree result that causes some to enter fruiting period seldom yields poorly down.

Summary of the invention

The present invention is the technical problem solving in traditional Pomegranate Garden planting process, invents a kind of new technology of low yield Pomegranate Garden transformation.

The present invention is for solving the problems of the technologies described above, the technical scheme of taking, and a kind of new technology of low yield Pomegranate Garden transformation, its special character is to comprise following process:

1, strengthen clay fertilizer water management and dig tree dish summer, cover grass or the wheat straw of 20 cm thicks after raking on tree dish, press a small amount of soil on it again, turn over early spring in next year on the spot. After gathering, to early winter, adopt bar ditch method basal dressing, 30～35 centimetres of ditch depths, mu is executed 3000 kilograms of high-quality farm manures, 3 kilograms of calcium superphosphate, 2 kilograms of NPKs. Before bud occurs, every strain imposes 0.5 kilogram of Diammonium phosphate (DAP), and the every strain of fruit expanding period imposes 0.5 kilogram, peanut cake fertilizer, 2 kilograms of calcium superphosphate, 2 kilograms of NPKs. Before rudiment in spring and after topdressing, respectively fill with 1 water at every turn.

2, the tree-like clump shape semicircle naturally that mostly is of reasonable pruning, adopts support branch summer, draws the methods such as branch that trunk branch angle the first transaction of a day's business 60～70 is spent. Take branch to process to the branch of excessive growth, auxiliary support branch, adjust the locus of branch. Fruit expanding period is wiped out and is wiped fruit branch and the partial blade near fruit. When winter cuts, skeleton branch and large-scale fruit-bearing shoot cluster are retracted to healthy and strong position, the prosperous branch filling space of selecting and remain, removes overstocked branch. The too much young sprout that erase and deeply prune and germinate spring in next year in time, removes Mi Shengzhi.

3, focus on flower and fruit management 0.3% potassium dihydrogen phosphate initial bloom stage for, 300 times of urea and 0.3% borax mixed liquor and sprayed once every 10 days, spray altogether 2～3 times. Bud stage is in few girdling 2 roads, 4～10 centimetres, interval, prosperous tree skeleton branch middle and lower part of flower amount. Remove in time imperfect flower and bud, after bearing fruit, remove in time and sick fruit, late flowers and fruits, malformed fruit and wormed fruit. When approximately 2 centimetres of fruit diameters, overlap 25 × 20 centimetres of plastic film bags after spraying an insecticidal bactericide, while gathering except bag.

4, the insect pest of integrated control disease and pest main diseases has early defoliation disease, black spot, dry rot, eriosoma lanigerum, tetranychus viennensis, dichocrocis punctiferalis, crape myrtle suede a red-spotted lizard, mulberry borer etc. Can be in conjunction with clear garden in winter, brush the scale insect on limb with scrub-brush, and trunk whitewashing; Between 5～June, do not spray broad spectrum insecticide, to protect and to utilize natural enemy as far as possible; Spraying 5 Baume degrees lime sulfurs before rudiment, 2000 times of liquid control leafeating insects of spray 5% r before rainy season set, after rainy season, interval 800 times of liquid of 2～3 50% carbendazim colloidal suspending agents of 10 days sprayings are prevented and treated disease, with trunk borers such as malicious label method control mulberry borers.

Technique effect

Technique effect of the present invention is, adopts technique scheme, can realize the object that improves pomegranate output, not only convenient operation of this mode, and can have the economic flow rate that time improves low yield garden pomegranate.

Detailed description of the invention

1, strengthen clay fertilizer water management and dig tree dish summer, after raking, on tree dish, cover grass or the wheat straw of 20 cm thicks, after gathering, to early winter, adopt bar ditch method basal dressing, 30～35 centimetres of ditch depths, mu is executed 3000 kilograms of high-quality farm manures, 3 kilograms of calcium superphosphate, 2 kilograms of NPKs. Before bud occurs, every strain imposes 0.5 kilogram of Diammonium phosphate (DAP), and the every strain of fruit expanding period imposes 0.5 kilogram, peanut cake fertilizer, 2 kilograms of calcium superphosphate, 2 kilograms of NPKs. Before rudiment in spring and after topdressing, respectively fill with 1 water at every turn.

2, adopt summer support branch method by trunk branch angle the first transaction of a day's business 60～70 degree, take branch to process to the branch of excessive growth, auxiliary support branch, when winter cuts, skeleton branch and large-scale fruit-bearing shoot cluster are retracted to healthy and strong position, remove overstocked branch, the too much young sprout that erase and deeply prune and germinate spring in next year in time, removes Mi Shengzhi.

3,0.3% potassium dihydrogen phosphate for initial bloom stage, 300 times of urea and 0.3% borax mixed liquor every spray in 10 days once, spray 2～3 times altogether. Bud stage, in few girdling 2 roads, 4～10 centimetres, interval, prosperous tree skeleton branch middle and lower part of flower amount, removes after bearing fruit and sick fruit, late flowers and fruits, malformed fruit and wormed fruit in time. When approximately 2 centimetres of fruit diameters, overlap 25 × 20 centimetres of plastic film bags after spraying an insecticidal bactericide.
