Huangpi only blooms without fruit. How should it be improved?

The flowering period of Huangpi fruit trees is generally after Qingming, and the rainy weather is relatively long after Qingming, which is not conducive to pollination and fertilization of Huangpi plant flowers. In economic cultivation, in order to improve the viability of male anthers and the receptivity of female stigmas, cytokinins and foliar fertilizers containing zinc, boron and magnesium are generally needed for pest control.

1. Artificial insemination

The phenomenon that wampee only blooms without fruit may be caused by pollination failure. In the natural growth environment, wampee is mainly pollinated by natural or biological factors such as wind, bees and butterflies. Artificial propagation may not be able to pollinate, and farmers need to collect pollen for artificial pollination.

Prune flowers

The phenomenon that wampee only blooms without fruit may also be due to the excessive number of flowers. Too many or too dense flowers will cause serious nutrient shortage or uneven supply, which will make the fruit unable to bear fruit. Therefore, flowers that are too weak, too dense or grow badly should be cut off in time.

3. Lack of

Underage can also lead to the phenomenon that wampee blossoms and bears no fruit. Generally, Huangpi fruit trees cultivated with seeds will not blossom until 8-9 years after grafting, and bear fruit later. The transplanted Huangpi fruit tree may bloom that year, but it is impossible to bear fruit. Just wait patiently for maturity.

4. Infected with pests and diseases

Infection with diseases and insect pests is also one of the reasons for the phenomenon that Huangpi fruit only blooms but does not bear fruit, especially because the flowering period of Huangpi fruit is getting warmer in early spring, and root rot or insect pests are easy to attack Huangpi fruit trees, so it is necessary to cut off the diseased branches in time and spray drugs on the diseased branches for control.

5. Sparse flowers and fruits

Thinning flowers and fruits reduces the nutrient consumption of trees, reasonably loads them, improves the nutrients needed for the development of surplus flowers and fruits, and is beneficial to flowering and fruit setting. Fruit thinning is generally carried out twice, the first time is usually about 7 days after flowering, and the second time is usually carried out after physiological fruit drop. Trees with frequent natural disasters such as late frost, varieties with low fruit setting rate or orchards should be kept sparse in the later period. Laiyang headline

6. Rational fertilization

Give priority to with organic fertilizer, supplemented by chemical fertilizer; Heavy base fertilizer, appropriate topdressing; Pay attention to the coordinated application of nitrogen, phosphorus and potassium fertilizer and the use of trace fertilizers; Apply fertilizers that are insensitive to fruit trees.

7. Scientific water control

The flowering and fruit setting period is the period when fruit trees need more water. If the soil is short of water, it should be irrigated in time and combined with fertilization. Irrigation should not be carried out in the hot sun at noon, but in the evening or morning.
