2 points of planting technology
2.1 Planting
Strong resistance to diseases and insects.
Planting time: Planting in mid-October or the following spring after the soil is thawed to before germination.
Planting distance: Planting with a row spacing of 2m×3m, planting 111 plants per 667 square meters.
Planting depth: the hole is 80cm deep and 1m wide.
Planting and fertilization: Apply organic fertilizer in layers at the bottom of the hole, cover the soil and fill it, and then plant it.
Post-planting management: Be steadfast when planting, water enough water, and cover with a layer of fine soil.
2.2 Soil management
Deep turn over
Deep turning can improve the aeration and water permeability of the soil, regulate the temperature of the soil, and promote the activity of microorganisms, so that the physical and chemical properties of the soil are fundamentally improved, which is conducive to the growth of the root system and the expansion of the absorption area.
For deep turning between rows and plantings, ditch 40cm deep and 100cm wide should be dug. It should be shallow near the root and gradually deepen outward, preferably 10-40cm.
Cultivator weeding
After each deep watering or rain, intertillage should be carried out to loosen the soil and ventilate, prevent compaction, preserve moisture and fertilizer, weeding, and reduce the breeding places for pests and diseases.
The depth of cultivating in early spring is 5-10cm, the depth of cultivating from April to August is 3-5cm, and the depth of cultivating in November is more than 10cm.
Reasonable intercropping
Chickens, ducks, etc. can be raised under the forest, and dwarf crops such as strawberries, peanuts, and sweet potatoes can also be planted between forests.
2.3 Water and fertilizer management
base fertilizer
Mainly organic fertilizer, fertilization amount is more than 5000kg per 667 square meters. Combine the soil with deep plowing after the fruit is picked and before deciduous, and apply compost, poultry, livestock manure and other base fertilizers. Applying basal fertilizer in autumn is conducive to root healing and growth, as well as restoring tree vigor and accumulating and storing nutrients. Water permeable once after fertilization.
After the fruit is picked, it is combined with deep plowing before the leaves fall, and base fertilizers such as compost, poultry, and livestock manure are applied.
Water soaked once after fertilization.
top dressing
According to the characteristics of pear tree's fertilizer requirement, it should be applied in batches before flowering, after the growth of new shoots has basically stopped, and during the period of rapid fruit swelling.
The pre-flowering fertilizer is mainly quick-acting nitrogen fertilizer.
For the second top dressing, nitrogen, phosphorus, and potassium elements should be properly matched.
The third top dressing is mainly to promote fruit enlargement and tree body accumulation and storage of nutrients.
Extra-root topdressing according to tree vigor, 0.5% urea or potassium dihydrogen phosphate can be sprayed.
2.4 Irrigation and drainage
In the dry and hot season, it is necessary to ensure a good water supply, and at the same time, it can be combined with the soil to fertilize and need to be flooded.
Pear orchards lacking irrigation conditions should strengthen moisture conservation.
Excessive long-term water in the soil and poor drainage can cause wet damage and even death. Therefore, it is necessary to drain water in time in the rainy season.
2.5 Prevention and control of pests and diseases
Manual control
Strengthen management, enhance tree vigor, and improve tree body's ability to resist diseases and insects.
In winter, remove the insect retina, remove dead branches, fallen leaves and weeds, and burn them together to eliminate overwintering pathogens and insect bodies.
Chemical control
Common pests and diseases: pear scab, ring disease, aphids, pear psyllids, pear web bugs, red spiders, etc.
Pear scab and ring disease: use 80% carbendazim 1500 times solution, 20% dysennium 1000 times solution or 40% Fuxing 8000-10000 times solution for prevention and treatment.
Aphids, Psylla sylvestris, Psylla stink bug: Spray 10% Aphid, 2000 times solution of Aphid, or 2000 times solution of 4.5% Lambda cypermethrin for control.
Red spider: spray aphids or 1.8% avermectin 2000 times solution for control.
