How to prevent nectarine fruit cracking? A full analysis of practical measures

Nectarine fruit cracking can seriously affect the quality of nectarines and the economic interests of growers. For this situation of cracked fruit, with an uneven surface and cracks that also affect the taste of the fruit, what exactly should be done? Last time, the editor introduced the causes of nectarine fruit cracking. Today, the editor will talk with everyone about how to prevent nectarine fruit cracking.

1. Choose varieties

There are many varieties of nectarines, such as Zhongyou No. 4 and Shuangxi Hong. When planting nectarines in different regions, you should choose the varieties suitable for your region according to the environment and climate conditions of the planting area. For example, if you are in North China, Northwest China and other areas with less rainfall, nectarine fruit cracking is relatively rare there, so varieties that mature at any time can be cultivated in that area. But in southern areas with more rainy and cloudy weather, you should try to avoid the rainy season in the south or choose early-maturing varieties with a lower cracking rate, such as Shuangxi Hong and Zhongyou No. 14.

2. Reasonable irrigation

Artificial irrigation in the orchard will appropriately increase the water content in the nectarine flesh, so maintaining the water content needed by nectarines every day can reduce the fruit cracking rate and even prevent it. For watering, it is best to use drip irrigation and watering methods, because this can make the soil in the orchard receive water evenly and provide a stable water supply for nectarines. It is very beneficial to the flesh cells of nectarines and can reduce fruit cracking. If continuous rainy weather occurs, drain the water from the orchard in time to avoid excessive water affecting the tree roots.

3. Bagging management

Carry out bagging once during the fruit-setting or young fruit stage of nectarines, but note that before bagging, spray an insecticide and fungicide once in the orchard. The purpose is to clear the pathogens and sources of disease in the orchard and on the young fruit. For bagging, you can choose paper bags or plastic bags, and if you have time, you can also make them yourself. After bagging, pay attention to the condition of the leaves and fruit, and deal with abnormalities in time. Remove the bags one week before preparing to harvest, but to prevent the nectarines from being sunburned after the bags are removed because they cannot withstand the stimulation of light, tear off the bottom of the bag and let the nectarines adapt slowly.

4. Thinning and pruning

Nectarine trees should not grow too tall. Keep the trees at a medium height and prune some weak and poorly developed branches, because nectarines growing from such branches have a higher fruit cracking rate. The branches cannot ensure the nutrients needed for nectarine growth. Pruning these branches saves nutrients and improves the ventilation and light penetration in the orchard, which is more conducive to nectarine growth.

The above are the methods for preventing nectarine fruit cracking. Apart from the first issue of variety, the other three can all be achieved through your own reasonable management. As long as you maintain the water and nutrients needed by nectarines in daily care, as well as the ventilation and light penetration between each tree in the orchard, the nectarine fruit cracking rate can be reduced a lot.
