The latest measures to control nectarine fruit cracking

Nectarine cracking will seriously affect the quality of nectarine and the economic interests of growers. What should we do about this kind of cracking with uneven surface and cracks that will affect the taste of fruit? The last small editor has introduced the reasons for nectarine cracking. Today, I will talk to you about how to prevent nectarine cracking.

1. Select varieties

There are many varieties of nectarine, such as Zhongyou No. 4, Shuangxihong, etc. When planting nectarine in different areas, it is necessary to select the variety suitable for your area according to the environment and climatic conditions of the planting area. For example, if you are in North China, Northwest China and other areas with less precipitation, nectarine cracking is rare there, so no matter when the variety matures, it can be cultivated in that area. However, in areas with more rainy weather in the south, it is necessary to avoid the rainy season in the south as much as possible or choose varieties with early maturity and low fruit cracking rate, such as Shuangxihong, Zhongyou 14, etc.

2. Reasonable irrigation

Artificial watering of orchards increases the moisture content of nectarine flesh appropriately, so maintaining the necessary moisture content of nectarines daily can reduce or even prevent nectarine cracking. Drip irrigation and watering is the best way to irrigate the orchard, because it can evenly absorb water in the soil and provide a stable water supply for nectarines. It is very good for nectarine pulp cells, which can reduce the cracking of fruit. If it encounters continuous rainy weather, the water in the orchard should be drained in time to avoid excessive water from affecting the roots.

3. Bagging management

Bag nectarines once at fruiting or young stage, but note that pesticides and fungicides should be sprayed once in the orchard before bagging. The aim is to remove the germs and pathogens from the orchard and young fruits. Bagging can be done in paper or plastic bags. If you have time, you can also make it yourself. After bagging, pay attention to the situation of leaves and fruits. If any abnormality is found, handle it in time. Remove the bagging one week before harvest. However, in order to prevent the nectarines from being burned by the stimulation of light after removing the bagging, tear off the bottom of the bag and slowly adapt the nectarines.

4, thin cut

Nectarine trees should not grow too high, to control the tree at a medium height, some weak, poorly developed branches will be cut off, because this branch out of the nectarine fruit cracking rate is higher. Branches can not guarantee the nutrition needed for nectarine growth, so 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 cracking method, in addition to the first variety problem, the remaining three can be achieved with their own reasonable management. As long as the nectarine needs water and nutrients in daily life, as well as the permeability between each tree in the orchard, the nectarine cracking rate can be reduced a lot.
