Recently, there were more pointed cucurbits in the sheds of Heguan Town, Qingzhou City, Shandong Province, but they did not know what caused them. The author learned from the survey that there are three main reasons for producing zucchini:
First of all, the vegetable farmers have left too many melons. Because the weather was fine some time ago, the zucchini grew more prosperous, so the vegetable farmer took a melon in accordance with each leaf, hoping to control the trees through fruit, resulting in too many melon strips, fierce competition for nutrition, resulting in a large number of melons Due to lack of nutrients supply, it became a sharp-headed gourd. The author suggests that when the vegetable grower should stay in the melon should be properly taken according to the growth of the plant, for the growth of robust plants generally take 4 to 5 melons per plant can be, must not be a leaf melon.
Second, the fertilizer is irrational. Appropriate increase in the amount of chemical fertilizers, can not be because of lower vegetable prices and reduce the use of fertilizer, resulting in poor nutrition of zucchini, pointed head melon increased, generally in accordance with the high-potash fertiliser 30 kg per acre can be about. At the same time, in the squash phase of zucchini, it is not possible to water a lot, and it must not be dry and damp, so as to avoid root injury after watering and affect the absorption of fertilizers by roots.
Again, the temperature and humidity are not suitable. The temperature difference between day and night in squash squash is bigger, the daytime temperature in the squashing period should not exceed 23°C, and the night temperature should be controlled at about 13°C. At the same time, we must pay attention to the removal of the old leaves of the lower part of the plant (leaves to keep the handle), in order to enhance ventilation, remove moisture, to avoid disease, affect the photosynthetic efficiency of the leaves, leading to the production of pointed head melon.
