The latest preventive measures for flower and fruit drop of dragon fruit in summer

Fire dragon fruit is a kind of fruit that people like, the market price is not low, the economic benefit is good, so more and more people plant, but in the summer high temperature period, dragon fruit is easy to fall flowers and fruit phenomenon, so how to prevent it? Let's get to know it with the editor.

1. Too much water, too little moisture

With too little water in the soil and dry weather, it is difficult for the plant root system to absorb enough water and nutrients to support the development of flowers and fruits, resulting in falling flowers and fruits. Too much water in the soil makes it difficult for plants to breathe and suffocate, which can easily affect the root system's absorption of water and nutrients, resulting in falling flowers and fruits. There are more rainy days in summer, when it is blooming and fruiting, the quality of pollen is poor, which is not conducive to pollination, and the flowers will fall off ahead of time.

Preventive measures: the tree plate can be covered with weeds or straw to prevent soil moisture from evaporating too fast. when it is dry or at high temperature, it can be drenched several times to supplement the nutrients needed for dragon fruit growth in time. Do a good job in the field drainage and irrigation system, timely drainage in the rainy season, so as to avoid stagnant water in the field, resulting in root suffocation, rainy summer, can dig deep drainage ditch, let more water in the soil seep out, and shallow loose soil, it is appropriate not to hurt the heel.

2. Lack of nutrients

When the nutrition supply is insufficient, the plant growth is thin, and the phenomenon of falling flowers and fruits will also be found, or the partial application of nitrogen fertilizer during fertilization will lead to excessive vegetative growth, that is, excessive growth, resulting in falling flowers and fruits, excessive application of nitrogen fertilizer and insufficient phosphorus and potassium fertilizer. it will affect the flower bud differentiation of the plant, the number of flowers is less, and the plant can not enter the reproductive growth period. The shedding phenomenon in the flower bud stage is mainly due to the insufficient application of boron fertilizer. when boron deficiency, the pollen tube is malformed, which affects insemination, abnormal flowers will appear, and calcium deficiency will also cause flower drop.

Preventive measures: in planting, we should ensure adequate supply of nutrients, reduce the amount of nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer, spray potassium dihydrogen phosphate on leaves to promote flower bud differentiation and reduce flower drop. The absorption of phosphate fertilizer is slow, so it should be applied in advance to promote nutrient accumulation and flower bud differentiation, and boron fertilizer should be supplemented in time to cultivate strong flowers and elongate pollen tube.

3. Disease

The disease is also one of the reasons for the phenomenon of a large number of falling flowers and fruits, and the common diseases causing falling flowers and fruits are canker.

Preventive measures: for this disease, fungicides or insecticides should be sprayed before flowering to protect the plants from invading germs. when the disease occurs, the diseased fruit leaves should be removed and sprayed to prevent the disease from spreading.
