Since November, the weather in the north has not been very good. Even in cloudy days, sometimes the sun has not been seen for four or five consecutive days, which has caused a great adverse effect on the growth of vegetables.
Even cloudy days are the time to test the management level of vegetable farmers. In particular, vegetable growers who grow cucumbers are very different from each other. Zhu Faxin, a vegetable farmer in Datian Township, Shouguang City, has been planting cucumbers. He seized the key to coping with the overcast days, which is to maintain a smooth transition.
Lao Zhu attached great importance to looking at the long-term weather forecast. Two or three days before cloudy days, Lao Zhu would remove as much cucumber as possible, reduce plant nutrient consumption, and ensure that the plants stored more nutrients. After picking the melon, immediately spray it with amidoxime, mesitectin, chitin (or Tianda 2116, etc.) to improve the disease resistance and cold resistance.
In cloudy days, especially in cloudy days, in addition to increasing the amount of light in time for the opening of the shed, it is necessary to supplement the nutrients that some plants need through the leaves. Even in cloudy days, the light in the shed is weak, the temperature is low, and the photosynthesis is weak. It is not sufficient to supply the respiratory depletion, the root absorption capacity is weakened, and the growth of leaves and fruits is impeded. At this time, vegetables need to be properly supplemented with organic nutrients. Lao Zhu will choose the weather is relatively good, can be ventilated at noon when spraying 100 times glucose, amino acid leaf fertilizer 1000 times, 1000 times the chitin conservation leaves, with amisida, metocin and other fungi to prevent fungi Bacterial diseases. Before closing the vent, make sure that the liquid is completely dry and avoid significantly increasing the humidity in the booth.
After the weather improves, especially when the weather is fine, the light conditions change too quickly, causing certain damage to the plants. At this time, appropriate measures such as shading and spraying with warm water are needed to give the plants a gradual and gradual adjustment period to avoid wilting. And other issues. After a cloudy day, the activity of the root system is weak, and the nutrients absorbed are insufficient to meet the needs of the plant. At this time, full nutrition foliar fertilizers, Amino Acids or nucleotides can be sprayed to supplement leaf nutrient and promote faster recovery of photosynthesis.
