The latest key points of florescence management of peach trees

The flowering period of peach trees is the most critical period of its growth and development, which is related to the fruit setting and yield of peach trees, and is the basis of high yield of peach trees, so how to manage peach trees during flowering period? Let's follow the editor to take a look at the key points of the management of peach flowering.

1. Fertilizer and water management

Huaiqiu is an important period for the absorption and utilization of nitrogen, calcium, magnesium and other trace elements in peach trees. After applying base fertilizer last autumn, it is recommended to apply 15 kg urea + 25 kg potassium calcium magnesium sulfate + 20 kg microbial agent per mu. Watering should pay attention to the two periods of pre-flowering and falling flower watering. Pre-flowering watering can promote flower bud germination, new shoot growth, increase fruit setting rate, and enter the period of young fruit formation, expansion and shoot extension after falling flowers. at this time, watering can promote the growth of new shoots, leaves and young fruits, and avoid fruit drop caused by lack of water.

2. Frost prevention

Peach blossom temperature is changeable, we must pay attention to prevent the impact of late spring cold on peach blossoms, the following methods can be used to prevent frost harm. Irrigation before flowering can reduce soil temperature, delay root activity, postpone flowering, reduce or avoid frost damage; whitening the tree trunk, but the tree body temperature rises slowly, delay flowering for 3-5 days, avoid and reduce frost; can also smoke and prevent frost in the orchard, fumigation can reduce soil heat emission, moisturizing effect, change and absorb moisture, increase ground temperature, reduce or avoid frost.

3. Artificial pollination

For the varieties with no pollen or low fruit setting rate, artificial pollination can be carried out when it is cold in late spring. first, the varieties with early flowering period, more pollen and strong affinity are selected to collect pollen and dry them indoors in a dry and ventilated environment. The temperature is controlled at about 20-25 degrees, and then stored in the fresh-keeping layer of the refrigerator. Artificial pollination can be dipped with a brush to take pollen on the stigma of female flowers, dipped in pollen once, can give 3 to 4 flowers. Generally pollination time is 9-10:00 or 4-5 pm on sunny days without wind. If it rains or meets late frost within 3 hours, repeated pollination is required.

4. Pest control

Before his uncle germinates, it is necessary to timely eliminate the primary infection sources of overwintering aphids, mulberry scale and brown rot, perforation and scab, and spray stone-sulfur mixture in the whole garden, or spray 1000-1500 times of enemy killing liquid or 2000 times of chlorpyrifos solution, which can effectively prevent diseases and insect pests.
