Planting and management of citrus fruit during ripening period!

After October, Shatang tangerine began to enter the fruit coloring and ripening period, the appearance and sweetness of the fruit mainly depends on this period of time, so this period of time is mainly to strengthen the tree potential as the core! Next, I will introduce you in detail!

I. soil management:

After entering October, the young orchard should continue to expand the hole to improve the soil, bury the organic fertilizer deeply, and choose to spray no-deep ploughing soil conditioner around the tree plate when the soil is wet after rain or before light rain, so as to loosen the soil, and the hole expansion and soil improvement should be completed before the middle of November. For the adult orchards that do not expand holes in the same year, no-deep tillage soil conditioners can be sprayed on the whole layer of the orchards after weeding, which can improve soil permeability, and the effect is better if biogas fertilizer or straw can be irrigated once after spraying.

2. Fertilization in soil:

Replenishing nutrients is the key measure to enhance the nutrition of trees. Attention should be paid to the application of fruit-picking fertilizer, which can be applied twice, once 7 days before harvest, mainly available nitrogen fertilizer, and no-tillage fertilizer can also be directly applied in orchards without no-deep tillage soil conditioner, which can not only provide available nutrients for fruit trees to absorb, but also have a good loosening soil effect and increase permeability. Another application after harvest, mainly organic fertilizer, to provide nutrients for heat preservation and anti-freezing and flower bud development in the coming year, the amount of fruit-picking fertilizer should account for about 30% of the fertilizer application during the whole growth period.

3. Foliar fertilization:

Foliar topdressing is the fastest fertilization method to promote the recovery of tree potential. 0.1mg/kg brassin + 0.3% urea + 0.2% potassium dihydrogen phosphate can be sprayed once before harvest and then sprayed twice after harvest, which can significantly improve the fruit quality, improve the cold resistance of the tree, promote the recovery of tree potential, and lay the foundation for high yield in the coming year.

4. Pruning:

Before and after Cold Dew cut and promote flowers on the main branches of the trees that continue to thrive, and continue to wipe off late autumn shoots, circle branches or twist branches to promote flowers on long and strong summer and autumn shoots, so as to promote the accumulation of nutrients in the tree.

5. Irrigation:

Rain Water is less in the fruit ripening period, so we should pay attention to prevent the damage caused by drought. If the weather does not rain for 10 consecutive days during the ripening period, we should irrigate it twice.

6. Pest control and anti-freezing:

Cold Dew was sprayed with 0.3 Lv 0.4 Baumetu stone sulfur mixture before and after fruit picking, and 1.0 Mel 1.2 Baomedo stone sulfur mixture was sprayed to control insects; when clearing the garden, the overwintering pests were brushed off, the branches and leaves of diseases and pests were cut off, and the fallen leaves, weeds and nuts in the garden were removed. After harvest, the trunk was covered with grass and then high soil was used to prevent freezing.
