When cucumber is cultivated, in order to improve the Growth potential of cucumber and enhance its disease resistance, it is grafted with pumpkin and other rootstocks, and a cucumber powder often appears after grafting. Compared with melon and melon meat, white powder has less water content and increased dry matter and ash. In the past, it was considered that no human touch is a new sign, but now people hate the white powder on the melon surface and are no longer popular. Therefore, the commercial property is reduced, and the economic benefits are affected. Therefore, it is important to clarify the cause of the formation of white powder and increase the gloss of cucumber melon, which is beneficial to improving its commerciality and increasing economic benefits.
The author has been engaged in vegetable production for many years. He has been a technical instructor for the construction of agricultural technology promotion system construction subsidies for many years. Through the observation of households and the exchange of growers, it has been found that cucumbers have numerous hairs on the young melons before flowering. The cucumber grows to form a spherical shape, and then gradually precipitates a white substance covering the melon surface to form a white powder. Combined with years of observation and investigation, the reasons for the occurrence of white powder are as follows:
There are many ways to cultivate cucumber, and different cultivation methods are closely related to the degree of white powder occurrence. Winter greenhouse cultivation of cucumber in the late April-May or early spring greenhouse cultivation occurred in May-June harvest, summer and autumn cucumber or autumn delayed cucumber harvest less in October, less harvest in November, June-August In open field cultivation, the more the harvest occurs, the more it occurs, which indicates that the occurrence of white powder is related to temperature. The higher the temperature, the more likely it is to occur, and the higher the humidity, the easier it is.
Different cucumber varieties are also related to the occurrence of white powder. The more white powder there is, the more white powder there is. The less the contrary, the less the actual production. In the grafting cultivation of cucumber, black seed pumpkin, gourd seed, and local climbing wall pumpkin (Indian pumpkin one) Kinds of more than the rootstock grafting, the difference between the occurrence of white powder is also very large, among which the local climbing wall pumpkins are mostly.
Some studies have pointed out that when a few rootstocks that have been strengthened by growth potential, superyunlong, light energy, etc., grafting, almost no white powder occurs, and whether white powder is related to the amount of silicon absorbed by cucumber, and silicon-enhanced crops related to white powder. Growth potential, improve its disease resistance. Cucumber grafted with less powder rootstock has poor disease resistance, but its melon skin color is light and the gloss is increased.
In summary, in the production of cucumber, it is necessary to combine the characteristics of the variety, choose the appropriate cultivation method, and the appropriate temperature and humidity management is the best economic cultivation method to obtain high quality and high efficiency.
