More than 90% of vegetable output comes from photosynthetic products produced by photosynthesis of leaves. Then, under low temperature and low sunlight, the plant's overall activity is reduced, the metabolism is slow, photosynthesis is blocked, and the whole plant is in a state of nutritional deficiency. Therefore, vegetable farmers should pay attention to regulating nutrient supply and fruit retention in management.
The plant itself has few synthetic nutrients and needs additional nutrition. Then, the type of nutrition and the way of supplementation are extremely important. In low-light weather, the watering interval is prolonged, and vegetables are prone to wilting due to lack of water. Therefore, vegetable farmers should also add water in a timely manner. At this time, add a functional foliar fertilizer (choose to be resistant to low temperature and promote photosynthesis The role of foliar fertilizer types). Of course, in the case of better humidity control in the shed, vegetable farmers can also water and flush fertilizer, but pay attention to the amount of water.
After the bad weather, vegetable farmers should allow time for the vegetables to rejuvenate, and they must not blindly retain fruits. Under normal circumstances, two melons, one large and one small, are left on the cucumber plant in the current season, with 2 leaves in between, to ensure that both melons can develop into high-quality melons. However, during this period of time, it is necessary to leave melons with about 4 leaves. This is because the continuous rainy weather in the previous period has significantly weakened the growth of cucumber plants, and it is necessary to allow time for cucumbers to rejuvenate. After continuous rainy days, the cucumber plants grew faster, but the stalks were weak and overwhelmed. If the way of keeping the melon remains the same, not only will the melon strips be easily deformed, the stress resistance of the plant will be reduced, and the probability of disease occurrence will increase. This is not conducive to the continuous stable and high yield of cucumber.
