Increasing the fruit setting rate is the most important part of the process of planting fruit trees, and cherry tree planting is no exception. How does the cherry tree increase the fruit setting rate? Here's how to improve the cherry fruit setting method.
One, timely watering
Big cherry has strong dependence on water, neither drought nor resistance. In order to ensure its normal growth, based on the timely pouring of four times of water before flowering, after flowering, before harvesting, and before freezing, the key water should be poured 10-15 days after flowering, and the amount of watering should be large. It is advisable to keep the soil water in the field at 60%-70%.
Second, improve the orchard
In order to avoid or reduce the damage caused by high temperature weather before and after cherry blossom to its flowering and fruiting, the microclimate should be built with a windbreak forest belt when it is located in the site. Should pay attention to listening to the local weather forecast, before and after the onset of high temperatures, take appropriate measures, before the flower can be 30-50 cm above the canopy shade net support, watering after flowering, promote normal flowering and fruit set.
Third, before the flower dressing
Before the flowering, the top dressing is early and the soil is thawed immediately afterwards to promote the flowering and fruit setting in the year. About one month after harvesting, it is a period of flower bud differentiation. Fertilizer should immediately be topdressed so that the flowering rate can be increased by 33.6%. At the same time, calcium, boron and other trace elements are added in an appropriate amount.
Fourth, control the tree potential
To get out of the vicious circle of regulators alone to control the tree potential. On the one hand, to reduce the content of nitrogen in the soil, rational use of phosphorus, potassium fertilizer and trace elements, from the source of control and prosperous. On the other hand, after the fruit is harvested, the Wang bar in the thick place of the tree crown is removed, and the Wang Tzu branch with useful value is pulled open and thrown lightly, so as to ease the growth and early flowering.
Fifth, decisive treatment
Virus Tree Virus Tree Spreading is a major obstacle to large cherry fruit set. Once discovered, it must be dealt with promptly. The onset of the whole disease must be removed, and thoroughly clean the roots within the tree hole; on the large branch of the disease should be completely removed, can not be changed, but not to pollinate.
Sixth, reasonable collocation
Pollination Almost all big cherries are self-evident. Many varieties are out of affinities, and light flowers do not produce results. Therefore, when cultivating large cherries, it is necessary to select two or more pollination cultivars that are similar to the flowering period of the main cultivars, and have good genes, yield, and quality, and the proportion should be about 30%.
Seven, science pruning
Large cherry xylem soft, thick ducts, cut mouth easy to flow glue dead trees. Therefore, it is necessary to grasp the key period of pruning: the top of the bud is changed to green for pruning; 10-15 days after the flower is cut off and about 10 days after harvesting, the pruning is performed during the growing period. These two periods of trimming, the wound is not easy to flow or less plastic flow. The second is to pay attention to methods: According to the habit of large cherry, we must use scissors and more hands, mainly summer scissors, supplemented by winter cuts. Timely on the back of the branch topping, twisting, pulling branches, stable tree potential, early flowering.
The above is the introduction of the method to increase the cherry fruit setting rate. Friends who grow cherries can refer to the above method of increasing the fruit setting rate and plant them reasonably.
