The quality of orchard management is directly related to the economic benefits of fruit farmers. In different periods, the focus of management is also different. According to Chen Dong, a fruit tree expert from the Sichuan Academy of Agricultural Sciences, fruit growers should focus on high-risk fruit trees and orchard soil management in the fall.
In the autumn of October, the fruit trees were replaced by high ones. Chen Dong introduced that the target of high-yielding varieties is to produce orchards and individual plant varieties with poor economic traits and low market prices, such as some tangerines, red oranges, and inferior navel oranges.
The species selection must first be based on the local climatic conditions, such as annual average temperature, accumulative temperature, sunshine hours, lighting, etc. If the temperature and illumination are insufficient (such as in the northern Sichuan region), the wide-leaf citrus varieties, such as the miscellaneous oranges, should be selected as much as possible.å´ å´ å—Ÿé¾‹ 嗟龋 嗟龋 嗟龋 庹 庹 庹 庹 庹 渥愕 渥愕 渥愕 渥愕 渥愕 渥愕 渥愕 渥愕 渥愕 峡 峡 峡 峡 ≡裉鸪 ( (16) ç—ˆ å—Ÿ å—Ÿ ? ? ?

Scion selection is best to choose the pure spring shoots, full shoots, robust branches, no pests and spring tips. Scion should be followed by picking, and cut leaves in time.
The tree crown is pruned to the tall tree with canopy closure. Before grafting, it must be pruned first, and the large branch of the inner ridge 1/4-1/3 should be sawed. At the same time, the dead branches, weak branches, diseased worm branches should be cut off, and the canopy should be airy and transparent. , improve graft survival rate.
The grafting tool is ready for the grafting knife (bud broach, branch grafting knife), branching scissors, whetstone, and good toughness bandaging film.
Grafting sites and the number of budding according to the size of the crown, generally 50 to 150 cm above the ground in the main branch, vice main branch, select the smooth part of grafting, grafting site branch thickness to 2-3 cm best, then the bud The number should be appropriate, depending on the size of the crown and then 8-20.
The grafting method should adopt single-bud abdominal connection and single-bud grafting in the autumn.
The single bud cuts the abdomen and then cuts a knife from the top to the bottom of the grafting site of the rootstock. The depth is a slight xylem, and the length is 2.5-3 cm. Then the cut cortex is cut off 2/3 to easily insert the bud. The cutting method of the scion is to cut a knife on the back of the bud head with a depth of slightly xylem. The length of the cut surface is 2-3 cm. Then it is inclined by 45 degrees at 1.5 cm at the lower end of the front bud. Then it is 1 cm above the bud. Cutting can be done; after the scion is cut, insert the rootstock incisions to form a layer alignment and tie them with a thin film.
In addition, branch cutting can also be used: cutting (saw breaking) the rootstock at the grafting site, smoothing with a knife, cutting a knife down from the slightly xylem part of the tough part, and about 1.5 cm deep, the incision should be smooth. The scion cuts off the phloem under the bud flat surface. The cut surface is about 1.5 centimeters long. Then it is beveled at 45 degrees on the lower side of the back and the upper part is left with 1-2 buds. When inserting the scion, pay attention to the formation of the alignment layer, and leave a "white line" above the cutting surface to facilitate healing. Finally, the film is tightly fastened, and the top of the wound and the scion must be bandaged. Then, a film storage bag is put on the bag, and the bag mouth is tightly closed to moisturize and prevent rain, which can improve the survival rate. When the scion sprouts, cut a hole in the top corner of the bag.
After the high-risk management, the inspections will survive after the spring, and if they are not grafted and survive, they must be promptly patched up. When the buds sprout in the next spring, the film is picked up to expose the buds (the thin film is released after the healing tissue grows). The anvil is generally divided into two parts, the first time in early March (spring grafting after budding survival), leaving 10-20 cm above the bud, the second time in the sprouting new shoots cooked After cutting off the remaining anvil, and using a knife to cut flat mouth dressing film protection, grafting the lower part of the trunk to be painted white, to prevent summer high temperature sunburn caused by stem dry cracking and morbidity, and promptly erase the sprout on the rootstock.
When the tree is connected to the anvil, it is necessary to consider leaving the hanging branch and the auxiliary branch. After the grafted species have a certain amount of growth, they are gradually cut off.
After the buds are pumped to grow to 20 centimeters, they will be tossed and promoted their skills. After each shoot, they will grasp about 20 centimeters in time to pick up the heart, prompting the acceleration of the formation of the crown. When reaching 40 centimeters or more, support the column to prevent it from being blown by the wind. At the same time, we must strengthen the management of fertilizers and waters, master the application of thin fertilizers, promote the restoration of tree crowns, and pay attention to the prevention and control of insect pests such as locusts, red spiders, scabs, swallowtails, leaf miners, scale insects, and hornbills.
Soil Management Chen Dong pointed out that the orchard soil management in autumn is also very important, mainly in the following aspects:
Deep plowing and improved soil deep plowing can ripen the soil, increase the thickness of the soil layer, promote the growth and development of fruit trees, update the root system, and enhance the absorption capacity and range of roots. This is a prerequisite for realizing early fruiting and high yield of fruit trees. Deep-turning and changing the soil must start from when the park is built, and then it will be expanded every year or deep in the whole park. Although the digging and planting ditch or hole was carried out at the time of the construction of the site, other unexcavated parts are still unhardened hard soil. Therefore, deep plowing and soil improvement is an indispensable task every year.
The form of deep plowing can be used in both the deep plunge and the deep plunge. Generally, after the fruit trees are planted, both sides of the fruit tree ditch are planted, and the soil is continuously expanded outwards along the ditch boundary. During the 2-3 year period, the orchard deepens year after year, finally deepens all deepen holes, and then expands once every few years to renew the root system.
The doubling time is carried out in the autumn (September-October) after the fruit is harvested. Take care not to damage the thick roots. It is best to fill the soil on the tumbling day to avoid long exposure of the root system to the air. , pouring water thoroughly to facilitate the restoration of the root. Near the neck should be lightly flipped so as not to damage the tree.
In soils with heavy soils, thin soil layers, or fruit plantations on flat soils with flat soils and low-lying land, these types of soils should focus on deep turning and soil improvement. Viscous heavy plate soils need to be treated with organic fertilizers, and charcoal, river sand, and sawn wood must be added. Can also adhere to long-term straw coverage, or planting green manure, to improve soil structure, fertility and fertility.
Drainage flood control Garden water damage to fruit trees: When the water content in the soil is about 17%, the fruit trees can grow normally. When the water content in the soil exceeds 21.2%, it often leads to lack of oxygen in the soil and increase of harmful substances, affecting the respiratory system of the roots. Other physiological activities, such as weak roots or fruit tree necrosis, poor shoot growth, yellow leaves, or even a large amount of early defoliation, poor growth, poor performance, and severe tree necrosis.
Dig a flood ditches at the top of the terraced orchard, 1m wide and 50cm deep; dig a back ditch inside the countertop, 50m wide and 30-40cm deep; dig a ditch in the orchard longitudinally along the gully, width 60cm, depth 40 -50 cm. To dig the main drain in the ground orchard, width 60-80 cm, depth 60-80 cm; open the road between the lines in the park, width 40-60 cm, depth 40-50 cm.
Shijifei autumn basal fertilizer can increase nutrient storage in the tree body, which is conducive to wound healing, promote new roots and decomposition of fertilizers, and is conducive to absorption and utilization in the spring. The amount of basal fertilizer application should be determined depending on the variety, generally early-maturing varieties increase the amount of fertilizer. Phosphate fertilizers have poor mobility and are easily fixed by the soil, so they must be mixed with organic fertilizers. Calcium fertilizer should be applied when basal fertilizer is applied, because calcium fertilizer will inhibit nitrogen activity when used as top dressing. Base fertilizer is commonly used: human waste, livestock and poultry manure, manure, cake fertilizer, compost, soil miscellaneous fertilizer, green manure, enzyme bacteria and other fertilizers.
