Description

A method for early high yield of pear sprout seedlings

technical field

The invention belongs to a method for planting and cultivating fruit trees, in particular to a method for early high-yield pear bud seedling establishment.

Background technique

Pear fruit is crisp, sweet and juicy, rich in vitamins and minerals, rich in nutrition, and has good medicinal value, and is loved by people all over the world. my country is the largest pear producer in the world, but for a long time, the cultivation mode and management level are backward, and the production efficiency is very low.

Pear is a perennial woody fruit tree. The traditional cultivation mode adopts the large crown and sparse planting mode. The tree has many layers and is difficult to manage. It requires a lot of labor costs; it takes 4 to 5 years from planting and gardening to production, and the economic benefits Late; after putting into production, the orchard is prone to canopy closure, leading to the breeding and spread of pests and diseases. At present, there is a shortage of labor force in rural areas of our country, and the cost of labor continues to rise. The development of early fruit and early high-yield cultivation techniques is an inevitable choice to reduce the technical difficulty of pear orchard management, reduce the production cost of orchards, earn early profits, and be economically efficient.

Contents of the invention

Purpose of the invention: The purpose of the invention is to solve the problems of difficulty in building gardens for large seedlings, high cost, late results and late benefits. The invention provides growers with an early high-yield method for pear sprout seedling gardening with low cost of gardening, simple technology, strong operability, easy management, the cultivation purpose of achieving early fruit and high yield, significant economic benefits and promotion and application value.

Technical solution: In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is as follows:

A method for early high yield of pear bud seedlings in garden construction, comprising the following steps:

(1) Selection of sprouts:

At the end of autumn, select buds with a dry diameter of more than 1cm, full buds, well-developed main roots, and more than 10 fibrous roots.

(2) Sprout planting:

1) After the orchard is leveled, excavate a planting ditch with a depth of 80-100 cm and a width of 80-100 cm along the north-south direction according to the row spacing of 3-3.5 m;

2) Put 40-50cm thick crop straw into the planting ditch;

3) Apply 5-10cm thick farmyard manure to the planting ditch;

4) Backfill the planting ditch with soil until it is level with the ground;

5) Water the planting ditch thoroughly to make the soil firm;

6) Plant the sprouts on the planting ditch with a spacing of 0.75-1m. The planting depth should be 1.5-2.5cm below the ground with the root neck buried, and the grafted part should be at least 5cm above the ground;

7) Water the planting ditch thoroughly;

8) When the soil in the planting ditch is slightly dry, cover the planting ditch with black plastic film or ground cloth, and compact the edges of the film or ground cloth with soil to increase the ground temperature, maintain soil moisture, prevent weeds, and promote root growth;

(3) Management in the first year after planting

1) Before germination, cut off the upper part of the rootstock at 0.5 to 0.8 cm above the bud sheet of the grafted variety;

2) Water once every 15 days or so until the end of May to maintain soil moisture;

3) after germination, wipe off the tender shoots that the rootstock takes out in time, and keep the tender shoots that the grafted variety buds send out;

4) When the branches of the grafted variety buds grow to 20-30cm high, set up a 2m high bamboo pole as a support, and tie the seedlings along the bamboo pole;

5) Erase the germinated branches on the branches in time to keep the single trunk of the grafted variety growing upwards;

6) In mid-May, spray 300-400mg·L ^-1 gibberellin solution on the weakened pear seedlings that have not grown to 20cm in length after the grafted buds germinate, spraying once every 15-18 days, and spraying continuously for 3-4 times;

7) Combine watering at the beginning of June, apply 25-30g of urea to each tree, apply once every 15-18 days, and apply 6-8 times in a row to ensure that the height of the saplings reaches 2-3m in the current year, and the trunk diameter is more than 80% Reach more than 1cm;

8) Find and repair the damaged plastic film or ground cloth, keep no grass in the row, mow weeds or rotary tillage in time, and keep the grass height between rows below 40cm;

9) Carry out pest control operations during the period;

(4) Management in the second year after planting

1) One week before germination, all the buds that are 80cm above the ground and the diameter of the trunk is more than 1cm are all bud-cut. For the xylem, it is advisable to saw a small amount of xylem sawdust; usually about 30-40 carved buds are processed. ;

2) Immediately after carving the buds, pour water once, combined with watering, apply 25-30g of urea to each tree;

3) After that, 25-30g of urea will be applied to each tree every 15 days combined with watering;

4) After mid-May, when the branches that have undergone engraved buds grow to 30-40 cm long, the branches are twisted. The specific method is to use the thumb and forefinger to pinch the rear part of the branch 2 to 3 cm away from the middle trunk, and twist the branch 180° clockwise to injure the xylem of the branch and make the branch and the main trunk form an angle of 50°;

5) Apply 25-30g of N, P, and K compound fertilizers to each tree in conjunction with watering every 15 days after the tip is twisted, and fertilize continuously for 4-6 times, and no longer apply urea alone;

6) Find and repair damaged plastic film or ground cloth, keep no grass in the row, mow weeds or rotary tillage in time, and keep the height of grass between rows below 40cm;

7) Carry out pest control operations during the period;

8) At the end of October, ditch and apply farmyard manure at a distance of 40 to 50 cm from the trunk, and apply 2 to 3 square meters of farmyard manure per mu;

(5) Management in the third year after planting

1) One week before germination, the buds that did not germinate after the buds were carved in the previous year and the newly added buds in the upper part of the middle trunk were carried out, and the method was the same as above;

2) Immediately after carving the buds, pour water once, combined with watering, apply 50-60g urea to each tree;

3) Apply 50-60g N, P, K compound fertilizer to each tree in combination with watering before flowering;

4) Fruit thinning is carried out in the first ten days of May, and 2 to 3 fruits are left on each branch depending on the size of the tree;

5) In mid-June, 50-60g of N, P, and K compound fertilizers were applied to each tree every 15-18 days combined with watering, and applied 2-3 times in a row;

6) Find and repair damaged plastic film or ground cloth, keep no grass in the row, mow weeds or rotary tillage in time, and keep the height of grass between rows below 40cm;

7) Carry out pest and disease control operations during the growth period;

8) Harvest the fruit after the fruit is ripe;

As a preferred option, the above-mentioned a kind of pear bud seedling construction garden early high-yielding method can realize the following output indicators:
