When is it suitable to grow chili peppers in greenhouse? What are the cultivation techniques?

Since greenhouse technology has been popularized and popularized, many growers have chosen to plant chili peppers in greenhouse, and the economic benefit is obvious. So when is it suitable to grow chili peppers in the greenhouse? What are the cultivation techniques?

When is it suitable to grow chili peppers in the greenhouse?

Many people think that as long as vegetables are planted in the greenhouse, they can be sown at any time. In fact, this view is rather one-sided, because although it can be achieved in operation, it still has some impact on quality and yield.

As far as pepper is concerned, if you choose to grow in a greenhouse, the planting time still needs to take into account regional factors.

1. Northern plain area

Due to the differences in climate and topography between the north and the south, the northern plain can choose spring sowing (planting in January-February) and autumn sowing (mid-early July-early August), which can not only go on the market earlier, but also sell at a higher price.

2. Southern hilly and mountainous areas

However, in the mountainous and hilly areas of southern China (Hunan, Hubei, Jiangsu and Zhejiang), hot pepper is usually sown from March to July every year.

Generally speaking, temperature is the biggest factor affecting the sowing time of hot pepper. No matter when it is planted, the temperature in the greenhouse should be adjusted above 20 ℃.

Second, what are the cultivation techniques of pepper in greenhouse?

1. Seedlings should be sturdy.

Whether you choose to sow your own seedlings or buy pepper seedlings directly, you should choose the stronger pepper seedlings that take about 35-40 days to plant. This is more conducive to the later decomposition of flower buds and fruit.

2. Heat preservation should be moderate

Although we talked about the importance of heat preservation of pepper in greenhouse, we should not keep warm too much. Too high temperature will restrain the growth of pepper, and it is also possible to grow too long and affect the quality of pepper. Therefore, the temperature in the greenhouse had better not exceed 30 ℃.

3. Don't control the water too much

There are also some growers worried about the excessive growth of pepper, which leads to excessive water control, poor pollination and poor yield in the early stage of pepper growth. Therefore, it is best to install drip irrigation equipment in the greenhouse, which can not only replenish the pepper with proper water, but also avoid overwatering.

4. Control the amount of fertilizer and large amount of fertilizer.

In the cultivation of hot pepper in greenhouse, there has always been a misunderstanding, that is, more fertilizer can grow better and faster, but the truth may be just the opposite. excessive fertilization will not only cause fertilizer damage, but also lead to the increase of soil salinity. Whether in terms of short-term benefits or long-term planting benefits, it is not a good choice.

By the same token, it is necessary to control the amount of medicine for chili peppers. On the one hand, too much medicine is easy to destroy seedlings, on the other hand, it will also reduce the disease resistance of chili peppers, causing large-scale diseases and insect pests.
