How to manage hot peppers for high yields? Latest tips shared
Chili pepper is a daily vegetable in our lives, and it has many varieties, while hot pepper is currently a relatively popular variety on the market, and farmers growing it can still get a decent return. To further increase the return, the only way is to start from the yield aspect, so how should hot pepper be managed for high yields? Follow the editor to learn about it.
1. Scientific ventilation
During the flowering and fruiting period, hot pepper requires a temperature between 15 and 35 degrees Celsius. If it is lower than 15 degrees Celsius or higher than 35 degrees Celsius, its flower bud differentiation will be poor, and it is also very prone to flower and fruit drop. Before 10 a.m., the greenhouse temperature must not be higher than 30 degrees Celsius, otherwise it will affect the pollination of hot pepper, so ventilation measures should be taken. About one hour after the greenhouse is opened, the vents can be opened wide, and then the size of the vents and the ventilation time can be decided according to the outside temperature. This can both supplement carbon dioxide and keep the temperature within a suitable range. In the afternoon, when the greenhouse temperature reaches 17 degrees Celsius, start closing the greenhouse, and at night keep it between 15 and 18 degrees Celsius, so that nutrients are transported normally during this period, avoiding excessive nutrient consumption caused by high night temperature, which can lead to excessive vegetative growth and poor flowering and fruiting.
2. Prevent plant death
Hot pepper is a shallow-rooted crop. Its main root is not very developed, and its root regeneration ability is also relatively poor. It is afraid of waterlogging and not tolerant of waterlogging, so the soil is required to be loose and breathable, and high-ridge cultivation should be adopted. High-ridge cultivation can not only enhance soil breathability and ensure the oxygen needed for root growth, but also help increase soil temperature, and is especially suitable for autumn-winter and early-spring production. In addition, high-ridge cultivation can also prevent root suffocation and root rot caused by excessive watering in early spring, and can also quickly drain rainwater after rain.
3. Reasonable pruning
Pruning can improve field ventilation and light penetration, which is not only beneficial to the synthesis and transport of photosynthetic products, but also beneficial to increasing yield and commodity value, and at the same time helps prevent the occurrence of pests and diseases. Generally, hot pepper mainly uses four-main-branch pruning as the main pruning method, removing side branches sprouting from the main branches to ensure that the four main branches grow upward in a coordinated manner. Pruning is generally carried out after fruit set, because at this time the plant is shorter and field ventilation and light penetration are good, so side branches can be retained to bear fruit. After the side branches set fruit, leave one leaf above the fruit and pinch off the growing tip. When harvesting the fruit, the fruiting side branches can be removed together. As the plant grows, branches and leaves interlace, which will affect ventilation and light penetration. Combined with fruit harvesting, remove the side branches in the inner canopy together to prevent excessive consumption of nutrients.
