What are the key points of high-yield cultivation techniques of hot pepper? It is very important to do these points well!

Pepper is an important condiment in China, and it is widely planted in many places. People in Hunan, Sichuan, Guizhou and other places are not spicy. It can be said that pepper is a best-selling product all the year round. So, what are the key points of high-yield cultivation techniques of hot pepper? It is very important to do these points well!

1. Timely shading

In the semi-shaded environment, pepper has stronger growth ability, lower leaf defoliation rate, less diseases and insect pests and higher pepper setting rate. According to the survey of professional data, the yield per plant of pepper planted in semi-shaded environment is about 5% higher than that in the field. Therefore, when we plant chili peppers, it is best to interplant with high-stem crops such as corn. In this way, it can not only increase the yield of chili, but also harvest corn and increase the source of income.

two。 Reasonable close planting

Reasonable close planting can make good use of light and soil fertility and promote the coordinated development of pepper seedlings. So as to improve the pepper setting rate of pepper seedlings and the quality of pepper. And compared with sparse planting, reasonable close planting can appropriately reduce air temperature, soil temperature and light intensity during the period of high temperature in summer, which is a necessary measure for high yield of hot pepper.

3. Fertilizer and water management

When applying fertilizer, one-time application of 40kg or so of chili pepper formula fertilizer, in the pepper seedling growth period can not be topdressing. However, if the soil fertility is poor or the ability to maintain fertilizer is weak, then it can be properly watered and combined with the right amount of available fertilizer. Then about 10 days after the pepper seedlings are planted, they usually enter the re-seedling stage. At this time, it is necessary to apply an appropriate amount of urea, and then appropriate shallow hoe to speed up the growth rate of pepper seedlings.

4. Four main branches pruning and branching method

When setting fruit, four branches with strong growth and good orientation were selected as the main branches, the rest of the same branches were cut off from the base, and 1-2 branches were left in each main branch, and the rest of the same branches were thinned.

5. Multi-main branch pruning and branching method

This method is suitable for cattle horn pepper and sheep horn pepper varieties, which can produce more fruit, developed root system, good plant growth and high yield, but it will also cause poor permeability and low early yield. In fruit setting, 5-6 branches with different positions were selected, but the sturdy and well-oriented branches were used as the main branches, the other branches of the same class were cut off, and 1-2 branches were left as fruit branches, and the other branches were thinned as soon as possible.

6. Intermediate ploughing and weeding

In the growing period of pepper seedlings, it is necessary to plough at least three times, mainly with a shallow hoe in the first time, appropriate depth in the second time, and finally, in the third time, be careful not to hurt the roots of the pepper. However, it mainly depends on the actual situation, if the soil hardening occurs after transplanting. Then you have to hoe twice or so, and after the chili leaves are topped, you have to hoe again. Then, before the pepper is closed, it is necessary to do a good job of soil cultivation and root preservation to improve the drainage of the field. It can not only avoid the lodging phenomenon of hot pepper, but also improve the water retention of soil.

If you want to achieve high yield of pepper, it is very important to do a good job of field management at the above six points.
