Due to poor management, cucumbers in the fruiting stage of winter greenhouses often have a break-up phenomenon. After careful analysis, the causes of cucumber breaks are generally as follows:
Too much fruit in order to increase production, farmers often take improper measures, such as those who can sit and stay melon, excess female flowers are not removed.
Harvesting is not timely Due to instability in the price of guarana, sometimes the vegetable grower waits for a high price and leaves the melon already grown on it, causing him to fall. The result of this is to break the balance between vegetative growth and reproductive growth of the plant, which results in excess organic nutrient consumption in the plant.
Inappropriate fertilization In the production, there are “multiple, chaotic, and miscellaneous†phenomena in fertilization by vegetable farmers. In particular, excessive application of compound fertilizer causes excessive concentration of soil solution, resulting in damage to the roots, and the root tip becoming rust color or local necrosis, causing root absorption. The weaker ability affects the normal growth of the plant.
Excessive spraying During the wintering of cucumbers in sunlight greenhouses, if the environment in the greenhouse is not properly controlled, it is extremely prone to diseases. Most vegetable farmers only pay attention to chemical control, but neglect agricultural control. The interval between application is short and the concentration is excessively excessive, resulting in phytotoxicity. The leaves of the plants become shriveled and the photosynthesis is weakened. In addition, random use of hormone pesticides causes cucumbers. Plant physiological disorders, so that the growing point of cucumber can not grow normally.
Improper watering Some vegetable farmers watering neither pay attention to weather conditions nor weigh the pros and cons of watering according to the growth laws of plants. If watering meets unfavorable factors such as continuous cloudy days, low temperature and strong cold currents, and the ground temperature is lower than 12°C, and the relative humidity of the soil is higher than 85%, the roots of cucumber will be damaged and the growth of roots will be inhibited. The impact is greater, which in turn causes rest.
