Malformed species of gourd and big belly melon: because it is unisexual and not pollinated, common in open fields. If the female flower is not fully pollinated, it will form a big belly melon. When nutrient moisture is sometimes good, sometimes it is easy to cause thin waist melon.
The big-headed melon also suffers: it is because the nitrogen fertilizer is too much, and the sudden increase in the expansion of the melon is caused. How to prevent: 1. The proportion of fertilization should be appropriate. The proportion of nitrogen and potassium is greater than that of phosphorus. The demand for potassium is greater than that of nitrogen. Therefore, the application of potassium fertilizer cannot be ignored. The amount of fertilizer applied is too large, and the soil salt concentration is high, which hinders the cucumber from absorbing water and nutrients. This not only affects the growth of cucumber plants, but also the shape of the melons. Therefore, the amount of cucumber to be fertilized should be appropriate.
With the harvest of cucumber, the nutrients are continuously consumed, and a stable and long supply of nutrients is needed. If the topdressing is neglected in the later stage, the cucumber is prematurely deficient due to lack of fertilizer, the effective harvesting period is shortened, the cucumber yield is decreased, and the deformed melons such as curved melons are increased. In order to ensure the needs of nutrients in the later stage, when the fertilization is combined with the fruit and vegetables, the handle of the fruit can be thickened, the water and nutrient transport can be smooth, the nutrient flow can be improved, and the fruit development and expansion can be promoted.
