The latest prevention and control measures for prickly ash falling flowers and fruits

Zanthoxylum bungeanum is a common condiment in daily life, which is widely planted in our country, and can also be used as traditional Chinese medicine. It can chill, relieve pain, kill insects and other functions, but also can be processed into soap, a wide range of uses. And many growers appear the phenomenon of falling flowers and fruits when planting, so what is the cause of the falling flowers and fruits of pepper? How to prevent and cure it? Let's get to know it.

First, the reasons for falling flowers and fruits

1. Lack of nutrition

In the flowering period of Zanthoxylum bungeanum, a lot of nutrients are needed for flower growth. In summer of photosynthesis, stomatal opening will emit a lot of aroma and attract a large number of aphids, resulting in reduced photosynthesis of leaves, malnutrition of plants, and serious flower and fruit drop. After fruit setting, the growth of fruit needs a lot of nutrients, and the supply of nutrients is insufficient, which makes the physiological flower and fruit drop seriously.

2. Bad environment

Low temperature and freezing injury, long-term drought, diseases and insect pests, overdense branch growth, insufficient light and too much Rain Water will affect the quality of pollination and fertilization, resulting in flower and fruit drop.

3. Diseases and insect pests

The harm of diseases and insect pests is also one of the main reasons for Zanthoxylum bungeanum falling fruit, which will reduce the fruit setting rate and cause the falling flower and fruit.

II. Prevention and control methods

1. Promote flower formation

The young trees can be stimulated with chemicals to promote flower formation, and ethephon can be used to control and promote flowers on the crown or vegetative branches of 4-5-year-old trees. The shoot shooting rate in late autumn is more than 95%, and the flower formation rate is about 50% to 90%. The untreated plants can hardly form flowers.

2. Drought and waterlogging prevention

The temperature is higher in spring and summer and Rain Water is deficient. It is necessary to water it in time to avoid drought. Generally, once a month, it is best to cover the soil after watering. If there is heavy rain in summer, it is necessary to do a good job of drainage and waterlogging to avoid dead plants.

3. Increase fertilizer application

Fertilize three times in time in combination with watering during the fruit setting period, one is young fruit fertilizer, generally 0.1 kg of nitrogen fertilizer and 0.5 kg of phosphate fertilizer are applied per plant, and the second time is fruit expansion fertilizer, which is applied to the soil of human roots through ring holes, generally 15 kg of farm manure, 0.1 kg of zinc fertilizer and 0.5 kg of phosphate fertilizer are applied to each plant. Finally, in the month before harvest, the main purpose is to restore the tree potential, only applying farm manure, generally using trench strip application or hole application.

4. Scientific pruning

It can cultivate good tree shape, reasonable irrigation, improve the ability of plants to resist adverse environment, pay attention to the prevention and control of leaf rust, longicorn beetles, aphids, gall midges, pepper scale and more than 20 diseases and insect pests at any time.

The above is the introduction of prevention and control measures of falling pepper and fruit. I hope it can help you. If you want to know more about it, please pay attention to us.
