Causes and Control Methods of Chili Stiffness

In the process of pepper planting, sometimes the fruit is small and hard, and this symptom is the capsicum fruit phenomenon. Capsicum fruit, also known as stone fruit, unisexual fruit, early symptoms become like strawberry fruit, thick and hard skin, long stalk, few seeds or seedless fruit, so what is the cause of capsicum fruit? How to prevent and cure it? Let's take a look.

First, the cause of the stiff fruit

1. Poor pollination: in the flowering stage of hot pepper, if you encounter a climate of low temperature or high temperature, that is, the temperature is lower than 10 degrees or higher than 4 degrees, it will lead to the abnormal growth and distribution of cross-pollination, and the female flowers can not be fertilized normally, so the unisexual fruit will grow. Due to the lack of hormone stimulation, the absorption of nutrients in this fruit is blocked, forming a stiff fruit.

2. Plant overgrowth: if pepper is planted in the field with poor ventilation and light transmittance, and is in an environment of high temperature and humidity, the plant will easily grow at a very fast speed, resulting in excessive growth, which will consume a lot of nutrients of the plant. as a result, the young fruit does not have enough nutrition during the growth, resulting in the stiff fruit, and the partial application of nitrogen fertilizer during fertilization will also lead to the excessive growth of the plant and form the phenomenon of stiff fruit.

3, the number of fruit is more: the growth and development of planting is generally poor, but the number of fruit is more, some fruits will stop growing because of lack of nutrition and form stiff fruit.

4. Improper management: the formation of ossified fruit may also be caused by artificial mismanagement. if there is a long period of drought and lack of water, or root burning is caused by improper fertilization, or the prevention and control of diseases and insect pests is not timely, these reasons will lead to poor plant growth and lack of nutrition, resulting in the formation of stiff fruit.

II. Prevention and control methods

1. Select improved varieties: varieties with strong growth, strong disease resistance and strong stress resistance should be selected when planting. In addition, it is best to disinfect and sterilize the seeds before sowing to reduce pathogens.

2. Rational planting: in planting, the row spacing must be controlled, the permeability between plants must be increased, and in the period of flower bud differentiation, it is best to adjust water, neither drought nor excessive watering can lead to overgrowth.

3. Strengthen field management: environmental control should be strengthened during flowering and fruiting period, temperature should be controlled between 15-30 degrees, soil moisture should be controlled at about 50%, which is caused by flowering growth, fertilization rate should be improved, and artificial pollination can be carried out if necessary.

4. Flower thinning and fruit thinning: according to the growth status of the plant, the excess fruit should be thinned reasonably to ensure that the plant can supply enough nutrients.

5. Strengthen the prevention and control of diseases and insect pests: we must pay attention to the prevention and control of diseases and insect pests, and we must deal with them in time after finding diseases and insect pests, so as not to miss the best time for prevention and control.

The above are the causes and control methods of capsicum fruit. I hope it can help you. If you want to know more about pepper planting, please follow us.
