Shine Muscat grapes enter the hard core stage about 15 days after fruit expansion, and the fruit changes from increasing in size to filling up the internal flesh. In some areas, this period is accompanied by the arrival of high temperatures, and attention should be paid to adjustments in field management.

1. Moisture management:

The water requirement during the hardcore stage is less than that during the primary expansion stage, but the soil still needs to be kept sufficiently moist. To ensure a constant temperature around the roots, but avoid flooding with water to prevent soil lack of oxygen and root rot.

2. Fertilization management:

Due to the high temperature, during this period, attention should be paid to the impact on field humidity and the prevention of air-burned fruits when applying fertilizer. It is recommended to choose organic water-soluble fertilizer for rooting, which can loosen the soil while promoting rooting. Increase soil aggregate structure and help maintain soil moisture stability. At the same time, pay attention to the use of silicon fertilizer. On the one hand, it improves the toughness of leaves and increases the photosynthesis efficiency of leaves. On the other hand, it improves the hardness of the fruit and increases the fruit's resistance to high temperatures.

Therefore, it is recommended to use Monband® MBT PULI-NANO(MBT SUS) and choose the balanced fertilizer Monband® KaDing® for a large number of elements. This period is the best time to absorb calcium fertilizer. Pay attention to supplementing calcium fertilizer, which can also increase the hardness of the fruit and improve its resistance to high temperatures.

3. Pest and disease control:

The hard core period is the key period for the prevention and control of grape diseases and pests, and attention should be paid to the prevention and control of pesticides.

4. Branch and leaf management:

During the hardcore period, more leaves should be left to block the sunlight and reduce the occurrence of sunburn. You can block light and reduce the temperature in the greenhouse by setting up shade nets and leaving grass in the fields.

5.Fruit management:

Small, diseased, scissor-damaged and deformed fruits should be removed to ensure the quality of the fruit. Maintaining an appropriate distance between fruit grains is conducive to fruit enlargement and coloring.
