Beware of overwintering cucumbers

Overwintering cucumbers are prone to rot or necrosis of cucumbers in the early stages of cucumber growth (particularly 7-8 cucumbers under the outlets in the winter greenhouses, and the occurrence of cucumbers under the laminating line or under the pressured bamboo rafts is heavier), which is commonly known as melon farmers. In the "bad" disease, light causes bald pegs (no growth point), and severe cases spread from the top of the vine to cause rot in the stems of cucumber stems, seriously affecting the yield of cucumber. The effect of single drug control is not good, causing more problems for vegetable farmers. Big loss. It has been observed that the overwintering of cucumbers is associated with plant calcium malnutrition and drip and bacterial infections in the shed. Comprehensive measures should be taken more effectively when preventing and controlling.
First, the maximum calcium absorption intensity of calcium supplementation in the early stage was the first time in the period of vine-bearing. The early melon cucumber melons have high absorption of calcium, and the demand for calcium increases, while the lack of calcium at the growing point shows the symptoms of calcium deficiency. The calcium-deficient cucumber was dwarfed and its internodes were short, especially near the top. The young leaves were small and the leaves curled upwards. At the later stage, the leaves dried up from the edge, and the leaves of the young leaves lost chlorosis and the growth point died. Therefore, calcium should be added after the winter cucumber hangs. In the production, before the flowering of the cucumber, calcium spraying is started. After the melon is sprayed, it can be sprayed with full-water-soluble Merrill Lynch, once every 10-15 days, and sprayed 2-3 times.
Second, reducing the amount of water droplets dropping onto the cucumbers and overwintering the cucumbers into the early stages of flowering and melons is low when the ambient temperature is low. Insulation often reduces the amount of ventilation, less ventilation results in a relatively large humidity within the greenhouse, plus a large temperature difference between the inside and outside the shed, the inside of the greenhouse is prone to water droplets, water droplets will drop in the cucumber growth point (under the tuyere and the pressure film Lines or membranes are easy to drip in under the bamboo drips. Low temperature of the water droplets will make the growing point catch cold, and the young shoots of cucumber will corrode as time goes by. When the dripping water is less, the phenomenon of dry leaves will appear more often, and drip will cause the plants to become rotten. head. In order to reduce the drops of water on the cucumber during production, a layer of film can be hung under the tuyere to prevent the dripping of the shed film directly to the growing point of the cucumber. It can also reduce the stimulation of the cucumber when the airflow is exchanged too quickly; The inner drip spot is often fixed. You can hang a wide-mouth bottle at the easy drip place to catch the drip, and prevent the cucumber top and leaves from driping. This is beneficial for reducing the humidity in the greenhouse and reducing the incidence of foliar condensation.
Third, the chemical control of calcium-deficient growth site where the resistance of pathogenic bacteria (especially bacterial diseases) is reduced, easily infected by pathogens (especially bacterial diseases) and the phenomenon of bad rotten head, and the growing point of cucumber at the drip site is also vulnerable. Bacteria harm bad head. To this end, calcium supplementation is used to spray pesticides and prevent infections in advance. When spraying, pay attention to spray the upper part of the plant.
4. Balanced fertilization The application of decomposed organic fertilizers or bio-organic fertilizers should be carried out using balanced formula fertilization to enhance plant resistance. At the same time the use of high-quality non-drop film, and do a good job in the temperature and humidity management.
