Key techniques for cultivation and management of Shatang mandarin during the fruit ripening period

After October, Shatang mandarin begins to enter the fruit coloring and ripening stage. The appearance and sweetness of the fruit mainly depend on this period, so during this period the main focus is on strengthening tree vigor! Next, I will introduce it to you in detail!

I. Soil management:

After entering October, for young orchards, continue to expand the planting holes and improve the soil, bury organic fertilizer deeply, and choose to spray a no-deep-plowing soil conditioner around the tree disk when the soil is moist after rain or before light rain, so as to loosen the soil. Expanding holes and improving soil should be completed before mid-November; for mature orchards that will not have holes expanded that year, after weed control, spray the no-deep-plowing soil conditioner over the entire orchard layer, which can improve soil permeability. If biogas fertilizer is applied once or rice straw is spread after spraying, the effect is even better.

II. Soil fertilization:

Supplementing nutrients is a key measure to enhance tree nutrition. Attention should be paid to the application of fruit-picking fertilizer. Generally, fruit-picking fertilizer can be applied in two doses. One is applied 7 days before harvest, mainly with quick-acting nitrogen fertilizer. In orchards where no-deep-plowing soil conditioner has not been applied, no-till fertilizer can also be applied directly, which not only provides quick-acting nutrients for the fruit trees to absorb, but also has a very good soil-loosening effect and increases permeability; the other is applied after harvest, mainly with organic fertilizer, to provide nutrients for heat preservation and freeze protection and for flower bud development the following year. The amount of fruit-picking fertilizer applied should account for about 30% of the total fertilizer application during the whole growth period. Business website: www.3456.tv

III. Foliar fertilization:

Foliar topdressing is the fastest fertilization method to promote recovery of tree vigor. A spray of 0.1 mg/kg brassin plus 0.3% urea plus 0.2% monopotassium phosphate can be applied once before harvest, and then sprayed 1-2 more times after harvest, which can significantly improve fruit quality, enhance the cold resistance of the tree, promote recovery of tree vigor, and lay the foundation for a bumper harvest the following year.

IV. Pruning:

Around Cold Dew, for trees that continue to grow vigorously and do not bear fruit, girdle the main branches to promote flowering, and continue to remove late autumn shoots. For long and vigorous summer and autumn shoots, ring-bark or twist the branches to promote flowering, so as to promote nutrient accumulation in the tree.

V. Irrigation:

During the fruit ripening period, there is relatively little rain, so attention should be paid to preventing drought damage. During the ripening period, if there is no rain for 10 consecutive days, irrigate thoroughly 1-2 times.

VI. Pest control and freeze prevention:

Before Cold Dew, spray 0.3-0.4 Baume lime sulfur mixture; after fruit harvest, spray 1.0-1.2 Baume lime sulfur mixture to control insects; when cleaning the orchard, brush off overwintering pests on the branches and trunk, prune diseased and insect-infested branches and leaves, and remove fallen leaves, weeds, and mummified fruit in the orchard. After harvest, wrap the trunk with straw and then mound soil high to prevent freezing.
