When is the flower bud differentiation period of southern early maturing pears?

Pears generally ripen in the month of month.

Pears, also known as Ya pear, big Ya pear, according to different varieties, the harvest time is divided into early and late, the growth cycle is very long, some varieties begin to bear fruit in 2-3 years, the full fruit period can be maintained for more than 50 years, pears according to the different varieties, its ripe harvest time is divided into early and late, generally mature in the month of the majority.

Pear trees are warm-loving, and need higher temperatures for growth, while low temperatures are required during the dormant period. The average annual temperature of pear trees is about 4-12 for autumn pear, 7-15 for white pear and western pear, and 13-21 for sand pear. When the soil temperature reaches above, the root system begins to move, and new roots grow at 6-7 hours; Growth stops when it exceeds 30 or below 0.

When the temperature reaches 5 or more, the pear buds begin to germinate, the temperature reaches 10 or more to bloom, and the flowering accelerates above 14.

Management

1. Fertilizer and water management

The demand for potassium and phosphorus began to increase when the fruit entered the ripening stage, and timely foliar spraying of potassium dihydrogen phosphate and rare earth could significantly improve the external and internal quality of the fruit. Pay attention to water control in the later stage, avoid partial application of nitrogen fertilizer, spray anti-falling sin if necessary, and control bugs, pear weevils, etc., or harvest in phases and batches to reduce fruit drop.

2. Reasonable pruning

In order to promote fruit coloring (ordinary pear or red pear) and improve the sugar content of the fruit, in addition to increasing potassium and phosphorus, it can also be thinned and cleared through autumn pruning, pulling branches and opening corners, and improving the light conditions of the tree, which is very beneficial to high-quality fruits. Depending on the ripeness of the fruit, it is harvested in batches, which greatly reduces the pre-harvest fruit drop.

1. Pears belong to autumn fruits, and most of them will ripen between early September and late October every year, and they will also begin to be marketed at this time.

2. However, there are many varieties of it, and some varieties mature earlier, such as osmanthus pear, which usually matures in June. There are also many ripening pears that ripen relatively late, such as cuiguan pears, crown pears, Fengshui pears, etc., and most of them only ripen around August.

1. Pears generally ripen in July and August, and are harvested from early September to late October. Pears ripen in late summer and early autumn every year, but the ripening time varies slightly depending on the growing zone.

2. The fruit of pears is nutritious, usually used for eating or medicine, ripe pear fruits are medium and large, thin skin and small core, juicy without residue, moderate sweet and sour, fragrant and long, crisp but not greasy, often called "natural nectar".

3. Pears are nutritious and contain a variety of vitamins and minerals, the vitamin B content of pears can be called the best among fruits, and the sugar content of pears that can be stored and kept fresh for 5-6 months is as high as 12% or more. Ripe pears have the effects of clearing the heart and moistening the lungs, relieving cough and asthma, quenching thirst, sobering up and detoxifying, and promoting digestion.

1. Pears ripen in July and August and are harvested from early September to late October.

2. In terms of flowering and fruiting habits, pear flower buds are easier to form and can generally bear fruit in a timely manner, especially varieties with high germination rate and low branching ability, or varieties with axillary flower buds bearing strength and bear fruit earlier. The fruiting branch of pear is actually a fruiting mother branch, which can be divided into four different types: long fruit branches, medium fruit branches, short fruit branches and axillary flower bud branches.

3. Adult pear trees are mainly short fruit branches, after flowering and fruiting, the new shoots swell to form a fruit platform, and 1 3 fruit side tips are produced on it, when the conditions are good, the flower buds can be continuously formed to bear fruit, but often need to form flower buds again in the second year of fruiting, and bear fruit in the next year.
