Causes and Solutions of Flower and Fruit drop of Apricot

People who plant apricot trees all know that the fruit setting rate of apricot trees is very low, and it is also very easy to drop flowers and fruits. Many apricot trees have a large number of fruit drops in the young fruit stage, which has a great impact on apricot growth and yield, and reduces the income of fruit farmers. So what is the reason why apricot trees lose their flowers and fruits? How to solve the problem? Let's get to know it.

1. Lack of fertilizer and water

Apricot has strong drought resistance and basically does not need to pay tax when growing, but if it is not watered in time in a serious drought, it will cause serious flower and fruit drop. In addition, in order to ensure the yield of apricot trees, fertilizer and water management is indispensable, especially for phosphorus, potassium and other trace elements. Once there is a lack of fertilizer, it will lead to lack of fertilizer in plant nutrition, weak tree potential, and abnormal flowering and fruiting. There are more flower buds but less fruit.

Solution: apricot blossom and fruit will consume a lot of nutrition, so it is necessary to apply quick-acting nitrogen fertilizer and a small amount of phosphorus and potassium fertilizer in time, and to apply nitrogen fertilizer and phosphorus and potassium fertilizer in the fruit tree expansion period to promote apricot flower bud differentiation and lay the foundation for high yield in the coming year. Water should be watered in time during drought to ensure sufficient water for plant growth, and drainage should be done during the rainy season to avoid stagnant water retting roots.

2. Low pollination rate

Apricot flower self-pollination rate is low, in the case of poor pollination quality, there will be a large number of flower drop phenomenon, even if it can pollinate, it will be early fruit setting, and a large number of shedding phenomenon will occur in the case of poor fruit quality.

Solution: when establishing the garden, the main varieties should choose the varieties with low abortive flowers and high fruit setting rate of natural pollination, and the general proportion of other pollination is about 1:3-4, and the flowering and fruit periods of the pollinated varieties and the main varieties should be the same. Artificial pollination can also be adopted to improve the fruit setting rate and reduce the phenomenon of falling flowers and fruits.

3. Climatic factors

Climate factors will not only affect apricot trees, but also affect all fruit trees. If you encounter cold and harsh weather in late spring, there will be a large number of falling flowers in apricot flowering period. After the result, the low temperature climate is more difficult to meet, but there will be a storm climate, which will also lead to fruit drop.

Solution: always observe the weather forecast and take precautions before bad weather to reduce losses as much as possible.

4. Diseases and insect pests

The diseases and pests that cause apricot trees to fall flowers and fruits are beetles, apricot weevil and almond wasps, which will gnaw on the young buds, flowers and fruits of apricot trees, resulting in a large number of flowers and fruits shelling, causing great harm, as well as diseases, once infected with diseases, flowers and fruits are easy to fall off in bad weather.

Solution: prevention of diseases and insect pests is more important than control, strengthen apricot fertilizer and water management, increase the application of organic fertilizer and phosphorus and potassium fertilizer, enhance disease resistance, timely prevention and control of diseases and insect pests.

The above is the introduction of the causes and solutions of apricot falling flowers and fruits. I hope I can help you. If you want to know more about it, please follow us.
