Measures for preventing and controlling nectarine cracking

Nectarine cracking will seriously affect the quality of nectarine and the economic interests of growers, for this kind of surface is not smooth, cracks will affect the taste of the fruit in the end how to do? Last time, the editor already introduced the causes of nectarine cracking. Today, the editor will talk with you about how to prevent nectarine cracking.

1. Select varieties

There are many nectarine varieties, such as Zhongyou 4, Shuangxihong and so on. When planting nectarines in different areas, it is necessary to choose the varieties suitable for your region according to the environment and climatic conditions of the planting area. For example, if you are in areas with less precipitation, such as North China and Northwest China, nectarine cracking is relatively rare, so varieties that mature can be cultivated in that area no matter when they are ripe. However, in the southern areas with more overcast and rainy weather, it is necessary to avoid the rainy season in the south or choose varieties with early maturity and low fruit cracking rate, such as Shuangxihong, Zhongyou 14 and so on.

2. Rational irrigation

Artificial irrigation in the orchard will appropriately increase the water content in the nectarine pulp, so keeping the nectarine water content every day can reduce the nectarine cracking rate or even avoid it. It is best to use drip irrigation and irrigation, because this can evenly receive water from the soil in the orchard and provide a stable water supply for nectarines. It is of great benefit to nectarine pulp cells and can reduce fruit cracking. If you encounter continuous overcast and rainy weather, the water in the orchard should be discharged in time to avoid the impact of too much water on the roots.

3. Bagging management

Bagging should be carried out during the nectarine fruit or young fruit stage, but it should be noted that pesticides and fungicides should be sprayed in the orchard before bagging. The aim is to remove the pathogens and pathogens from orchards and young fruits. Bagging can be made in paper or plastic bags or made by yourself when you have time. After bagging, you should pay attention to the leaves and fruits, deal with the abnormal situation in time, and remove the bag a week before harvest, but in order to prevent nectarines from being burned by light after bagging, you should tear off the bottom of the bag and slowly let the nectarine adapt.

4. Thinning cut

Nectarine trees should not grow too high, but should be controlled at a medium height and some weak, stunted branches should be cut off, because the nectarines grow out of such branches with a higher rate of nectarine cracking. Branches can not guarantee the nutrition needed for nectarine growth, but these branches can be cut off, which not only saves nutrients but also improves the permeability in the orchard, which is more conducive to the growth of nectarine.

The above is how to prevent nectarine fruit cracking methods, except for the first variety problem, the other three can be achieved with their own reasonable management. As long as the nectarine needs to maintain the daily water and nutrition, as well as the permeability between each tree in the orchard, the nectarine fruit cracking rate can be reduced a lot.
