Fruit Bag for Orchard Management Before Bagging - Agriculture
Reasonable pruning: The bagged orchard should adopt a reasonable tree structure. Apples and pears are mainly small crown sparse layer shape, base three main branches improved spindle shape, pruning is mainly light cut and thin cut, combined with winter and summer cut, adjust the number and spatial distribution of the resulting branch groups to solve wind problems. , Light problem; peach mainly shrinks weak branches, thins out the prosperous and long branches, throws the fruiting branches, and maintains the moderate tree vigor; grapes mainly thins out the dense branches, re-cuts the weak growing branches, and does a good job of wiping and tying the vines.
- Strengthen soil, fertilizer and water management: The bagged orchard should strengthen soil improvement, so that the depth of the orchard's live soil layer reaches 80cm. While deepening the soil, mountain orchards store rainwater as much as possible. In addition, the bagged orchard should adopt the raw grass system to increase the soil organic matter content, improve the soil aggregate structure, and maintain water and soil. The grass species should be white clover, ryegrass, etc. Bagging orchards should increase the application of soil and miscellaneous fertilizers, while applying borax and zinc sulfate and other micro-fertilizers; topdressing should be mainly nitrogen fertilizer to promote the growth and development of fruit trees; spray once 2 weeks and 4 weeks after flowering Amino acid calcium body fertilizer can effectively reduce or prevent the occurrence of bitter acne. Generally, watering is carried out before flowering and before bagging, so that the soil moisture content is maintained at 70~75% of the field water holding capacity.
- Flower thinning and fruit thinning, reasonable load: The orchard needs to be artificially assisted for pollination or bees during the flowering period; before bagging, the flowers and fruit should be thinned strictly, the load of the tree should be adjusted, and the flower-fixed fruit technology should be implemented. For tree species such as apples and pears, leave 1 strong inflorescence at a distance of 20-25 cm, and 1 fruit per inflorescence, 1 fruit at a distance of 10-15 cm for peaches, and 1 ear for each new shoot of grapes, each ear Leave 50-60 grains, and finish the flower thinning and fruit thinning one month after the flowers fall.
