Nectarine flower preservation and bagging technology

Flower protection and fruit thinning

Nectarine has a large amount of flowers, it has a strong fruitful self-fruiting rate, and it has a high rate of fruit set. Generally, it needs to carry out thinning and fruit thinning. Can be combined in early spring with a flowering flower before a flower cutting to close the dense flowering branches and weak flower branches properly removed, and depending on the fruiting branches and posture and short cut middle and long fruiting branches, in order to appropriately reduce the amount of flowering. In the southern region, due to early winter cold and late frost damage in some years, fruit thinning is generally adopted. The first fruit thinning can be used to distinguish the size of fruit after the flower has been cut. According to the amount of results, the thin fruit, the deformed fruit, the disease and fruit, and the twin fruit should be removed first, and then the excess fruit should be sparse. The second round of fruit thinning was carried out in the early stage of hard core. The amount of fruit remaining was determined according to species, tree vigor, and yield target. The general principle was: strong tree branches remained, and large fruit varieties remained, small and medium fruit varieties were appropriate. Stay longer.

Under normal circumstances, nectarine does not need fruits, such as pests and diseases, natural disasters, when the weak trees are strong, they can spray 0.2% borax liquid at the early flowering stage, pay attention to the application of nitrogen fertilizer in production, pay attention to the application of phosphorus and potassium fertilizer, strengthen artificial pollination, engage in Good pest control and other measures can achieve ideal results.

Fruit bagging

Fruit bagging, in addition to preventing peach borer, peach aphid, anthracnose, brown rot and other hazards, can also improve the coloring of the fruit, increase the smoothness of the peel, reduce fruit fiber and purpurin.

The bagging is carried out after fruit thinning, and is generally completed before the main fruit of the local pod enters the fruit. Mainly in late April. The first set of reliable fruit varieties, the latter set high fruit drop rate.

In China, old newspapers are used instead of paper bags. A triangular bag or a square bag is made, one end is open, the sleeve is put on the fruit, the bottom is tightened, and the thin silk thread is used to fix it on the branch. The paper bag is torn from the bottom during the fruit coloring period.
