Latest Technical Methods and Tutorial for Nectarine Summer Management
Nectarines are grown in many regions of China, but to achieve high yields and good quality when growing them, the first step is to improve one's own cultivation techniques. Summer is a relatively critical period for nectarines, and even a slight management mistake can have a huge impact on yield and quality. So how should nectarines be managed in summer? Let's find out together.
1. Controlling vigorous growth
Summer is the peak growing season for nectarine plants. At this time, branches and shoots grow relatively quickly, so fertilizer and water must be controlled, especially nitrogen fertilizer, to avoid excessive shoot growth that competes with the fruit for nutrients and harms fruit growth. During the annual growing season and after fruit harvest, never apply too much nitrogen fertilizer, to avoid excessive growth. At the same time, buds should be removed promptly. Useless secondary and tertiary shoots, as well as buds on the upper side of branches, should be removed in time. If removal is not timely, branches should be thinned promptly to maintain good canopy ventilation and light penetration. A flower-promoting agent can be applied to the main trunk to control excessive shoot growth.
2. Flower and fruit thinning
Nectarines themselves have an extremely high fruit-setting rate. If flowers and fruits are not thinned in time during production, it will lead to poor fruit development, smaller fruit size, and reduced commercial value of the fruit. Therefore, strict flower and fruit thinning must be carried out in production. According to the growth vigor of the fruiting branches, thin flowers and fruits in time before flowering. Generally, strong branches keep 4-6 flowers and retain 2-3 fruits; medium branches keep 2-4 flowers and retain 1-2 fruits; short and weak branches keep double flowers and retain a single fruit, or are thinned completely. Ensure 120 medium branches per square meter of the tree, as this is conducive to full fruit expansion and improves commercial value.
3. Bagging
Nectarines are different from other peaches. Their surface is hairless, making them extremely susceptible to fruit rust infection. Fruit rust occurs very easily, reducing commercial quality and affecting returns. Therefore, control measures must be strengthened: strictly control branch density, keep the orchard well ventilated, and in rainy seasons manage water intake and drainage to reduce orchard humidity and control diseases. Alternatively, use bagging to protect the fruit. At the same time, spray chlorothalonil, new high-lipid film, and zineb solutions to control diseases, keep the fruit surface clean, and improve fruit commercial quality. Generally, alternate the above agents every 7 days.
4. Enhancing fruit flavor
In production, nectarines are very prone to a bland flavor. The main reasons for this are excessive water supply, unreasonable fertilization, and premature harvest. To enhance fruit flavor, water supply can be restricted. During the fruit expansion period of nectarines, if the soil is not excessively dry, it is best not to water easily, as this helps increase dry matter accumulation and enhance flavor. During the flowering and fruiting stage and the fruit expansion stage of the plant, spray Zhuangguodiling once each time, which can promote sugar accumulation in the fruit, making the fruit sweeter and more fragrant. Harvest at the proper time.
