1. The weeds, litters, pests and diseases, and trunks in the orchard of Qingyuan Garden are the overwintering sites for pathogenic pests in the old bark joints on large branches. To eliminate the overwintering pathogenic pests, they must be carefully cleared after harvesting. Park, scrape old skin, scrape tree spots, cut dry branches, remove weeds, and then concentrate on burning or digging deep.
2. Shaving trees orchards The sandy soils and loam soils with good soil conditions can be deep-rooted under the trees by 20 to 30 centimeters to increase the permeability of the soil and freeze the dead insects in the soil. It has been observed that the apple fruit borer is overwintering and mostly distributed in the top soil layer of 1 meter deep and 10 centimeters deep. Adhere to the fruit trees after the autumn every time. Using the soil between the trees to deepen the soil around the tree trunk can make the larvae of peach borer easier to unearth in the coming year, which greatly reduces the damage of peach borer. If the condition of the orchard is not good and there are many sticky knots and stones, then deep plowing should be done year by year. Deep plowing requires the smashing of the clods, the mixing of some of the finely decomposed organic fertilizer, and the sealing, solidification, and then watering.
3. Shi Jifei, as the saying goes: "Fertilizer is an orchard treasure, but it can be used very well; the basal fertilizer is applied well, and the yield of fruit trees is high." Because of the long time required for decomposition and decomposition, it is better to apply it before falling leaves after fruit harvesting in the autumn. At this time, the ground temperature is high, the decomposition is fast, and the trees have not been fallen. It is beneficial to fruit trees to accumulate nutrients, and it needs to supply the next year's trees. The roots of wounds can also heal in the year. The experiment showed that early application of basal fertilizer after fruit collection was faster than in winter and early spring next year, which can increase the fruit setting rate of fruit trees by 8% to 9%. The amount of fertilization is based on high-quality farmyard manure, and it must achieve a pound of fruit and manure, produce more than 2,500 kilograms of fruit orchards per acre, and increase the amount of fertilizer to reach the standard of 0.5 kg of fruit and 1 kg of manure. Conditional orchards can be blended with phosphate fertilizers to increase organic matter quality and color.
4. Winter irrigation In order to prevent the winter drought of the fruit trees, winter irrigation may be performed before the fruit trees fall to the soil and freeze. An orchard without water can provide snow to the orchard in the winter to increase the ability of fruit trees to withstand drought and cold in winter. You can also use winter leisure to fill in orchards around the orchard to prevent the orchard from running water and running fat.
