Causes and control methods of eggplant stiff fruit

Eggplant is no stranger to us, and it is one of the common melons, fruits and vegetables in our life, which is widely planted in an all-round way, but with the planting area of eggplant, the phenomenon of eggplant is becoming more and more common and more and more serious, which causes great losses to farmers and hinders the development of eggplant planting industry. So what is the cause of eggplant stiff fruit? How to prevent and cure it? Let's take a look at the pro-farm network.

1. Planting environment

In the eggplant seedling stage, if it encounters the environment of high temperature, high humidity and insufficient light, it will lead to slow plant growth, weak flower stalk, short style, weak plant growth and poor development, without enough nutrients to blossom and bear fruit. And the fruit is also prone to the phenomenon of stiff fruit.

Prevention and control methods: the temperature must be controlled during the whole growth process of eggplant, generally, the temperature is below 30 degrees during the day, and the high temperature should not exceed 35 degrees, while the temperature at night should be about 15-20 degrees, not less than 14 degrees, especially before and after flowering, if it encounters overcast and rainy weather, can increase light intensity, timely drainage and waterlogging prevention.

2. Lack of water

In the fruiting period of eggplant, there is a large demand for water, but at this time, drought and water shortage, low temperature and poor slow seedling result in poor plant growth, which also provides favorable conditions for future ossified fruits.

Prevention and control methods: in the eggplant fruit period, timely and appropriate watering should be carried out, but it is not easy to water too much, so as not to cause too much water in the soil and cause root growth problems. Watering must be evenly watered and thoroughly watered, and ventilation should be strengthened after watering. Drainage should be done in time in cloudy and rainy weather.

3. Improper fertilization

If the excessive application of nitrogen fertilizer is blindly applied in the process of planting, the plant will be overnourished due to nitrogen, and the occurrence of stiff fruit will be greater. In addition, excessive application of potassium fertilizer will lead to plant overgrowth, but nutrients will not be transported to the fruit. Make the fruit lack of nutrients, resulting in stiff fruit.

Prevention and control methods: when applying fertilizer, we should master the correct fertilization technology, choose fully mature organic fertilizer as base fertilizer, base fertilizer must be fully applied, and pay attention to the reasonable combination of nitrogen, phosphorus and potassium fertilizer when topdressing fertilizer. In addition, we should also pay attention to trace elements such as calcium. If there is a small amount of stiff fruit, foliar fertilizer can be sprayed to promote plant growth and reduce the number of stiff fruit.

4. Drug influence

In order to increase the fruit setting rate and increase the yield, some farmers often use drug hormone treatment to increase the fruit setting rate, although the fruit setting rate has increased, but the plant can not supply the nutrition of fruit growth and development, forming stiff fruit. In addition, some flower and fruit protection and anti-falling hormone use excessive dose and high concentration will also lead to the occurrence of stiff fruit phenomenon.

Prevention and treatment methods: the correct use of these drugs, should not be excessive, excessive application, found that the phenomenon of stiff fruit should be removed in time to avoid the consumption of nutrients and reduce the number of stiff fruit.

The above are the causes and control methods of eggplant fruit brought by pro-agricultural network. I hope it can help you. If you want to know more about eggplant, please pay attention to pro-agricultural network.
