First, pay attention to the method of colonization During the interview, the reporter learned that there are two main problems in the current planting process: First, most vegetable farmers still adopt flat hoe cultivation when planting color peppers. The color pepper root system is relatively weak, under the same management conditions, flat ridge cultivation is not as good as ridging cultivation survival rate. Therefore, it is recommended that vegetable growers adopt ridging and colonization when planting, but now the weather is hot and the ridge should not be high when ridging and colonization, so as to prevent the temperature on the ridge from being too high, affecting the growth of the color pepper, and it is more appropriate to use small ridges (5-8 in height). Centimeter can be), this can prevent rooting and dead trees after watering, improve the survival rate of pepper. The second is that the method of preventing high ground temperature is wrong. Because the light is strong and the temperature in the greenhouse is high, the soil also maintains a relatively high temperature. To avoid the adverse effects of higher ground temperature on the roots of the bell pepper seedlings, many vegetable farmers watered the peppers before they were planted and wait for the water to infiltrate. Planting colored peppers again is not scientific. Because the first watering and then colonization of the soil and into the mud easily, so that the soil is easy to dry after the consolidation, poor ventilation, prone to dead trees. In this regard, it is recommended that the vegetable growers should be watered after planting. In the process of planting, attention can be paid to the time and method of colonization, for example, planting at around 5 pm, and planting water in a small area and then watering to prevent the seedling root from being baked for a long time by high ground temperature. Second, shade can not be ignored When the current high temperature and strong light, the temperature in the greenhouse will be as high as 40 °C or more, it is not suitable for the growth of color peppers, and seedlings are prone to be burned by strong light. Therefore, attention should be paid to the cooling of the shade. In general, the daytime temperature of the greenhouse should be controlled at 32°C and 18°C ​​at night. There are various methods for reducing the temperature in arch shelters. For example, vegetable farmers in Zhoujiazhuang, Jitai County chose to apply cooling agents to the greenhouse film and the second membrane to reduce the temperature. There are also vegetable farmers splashing mud or built-in shading nets for cooling. “Covering the shade net must be aware that in the absence of strong light, it is best to uncover the shade net, otherwise it will affect the flowering results of the color pepper. Every year there is a greenhouse where the fruit is affected by the peppers. Carefully think about it. Sunshade net coverage caused by too long." During the interview, a vegetable farmers reflected. Third, prevent and cure dead trees in time After planting bell pepper, because of root diseases or excessive watering, the dead trees often appear after rainwater irrigation. This requires the farmers to identify and treat the disease. Dead trees caused by root diseases: The diseases that cause the roots of dead trees in hot peppers mainly include diseases, the root rot disease (Phytophthora root rot and Pythium root rot) and bacterial wilt. This kind of disease should be mainly prevention. It is recommended that vegetable growers spread 1 to 1.5 kilograms into the planting trench per mu before planting and mix well with the soil, which can effectively prevent the root diseases of the pepper. Or, after the colonization, silver falco, Kate, etc. are used for irrigating. Dead trees caused by roots: When the peppers are planted by pouring water, the seedlings are generally not watered, so as to avoid causing excessive soil moisture, causing root diseases and dead trees; after entering the flood season, rainfall increases, and the color pepper The root system is weak. Management during this period is to prevent rainwater canopies. It is recommended that the shelter vent be closed before the heavy rain. If it is improperly protected, rainwater shall be drained out of the shed in time after the rainwater is flooded, and then water shall be poured again to increase the air permeability of the soil. Under necessary conditions, Hymexazol, Preco, etc. can be used to prevent root diseases.
