How to manage nectarine from flowering stage to young fruit stage 1, fertilization management
Nectarine planting requires fertilization before planting, before flowering, before fruiting and after harvest. Organic fertilizer should be applied as base fertilizer before planting. Nitrogen fertilizer should be applied before flowering to promote flower bud differentiation. Potassium fertilizer should be applied at the time of fruiting to make the fruit swell. After fruit picking, compound fertilizer should be applied.
2, plastic pruning
In order to prevent too many branches from absorbing nutrients, you can prune oil peach trees regularly. In summer, we should wipe off the useless buds on the new shoots that grow to about 5 cm. In autumn, we should trim the long branches to about 40 cm and cut off the weak branches directly.
3, pest control
The main diseases of nectarine are botrytis cinerea and bacterial perforation, and the pests are aphids and hawthorn red beads. When preventing diseases, you can spray isoprocarb and use 20% fenpropathrin emulsion to kill fenpropathrin 3000 times or 2000 times to prevent pests from affecting the harvest.
4. Preventive measures
From flowering to young fruit, nectarines can be thinned and pitted. In order to promote fruit, foliar fertilizer can be sprayed. When stunted, deformed and diseased fruits are found, they can be picked immediately, leaving healthy and complete fruits.
