Protect sweet potato fruit and vegetables during fruiting period

The protected vegetables entered the peak period of the results, and also entered the peak period of water absorption and fertilizer absorption. Therefore, we should fully understand the fertilizer requirements of fruits and vegetables during this period, so as to scientifically and rationally fertilize. At the peak of fruit growth, the absorption ratio of nitrogen, phosphorus and potassium is different from that in the early growth stage. At this time, more potassium fertilizer supply is required, the demand for phosphate fertilizer is stable, and the demand for nitrogen fertilizer is increased, but the nitrogen demand is lower than potassium.
In conversations with farmers, we found that they generally believe that phosphate fertilizer, urea, and ammonium bicarbonate can be used as fruit fertilizer; and that the more fertilizer is applied, the higher the yield. This caused excessive nitrogen application, excessive phosphorus application, and insufficient potassium fertilizer during the fruiting period. When there is too much nitrogen fertilizer, it is often found that the leaf area is increased and the leaves are dark green. In case of severe overdose, the leaves of the plant will be thick and hard, the leaves will be twisted, the fruit will be reduced or the melon strips will be distorted. When there is too much phosphate fertilizer, there will be symptoms of chlorosis such as zinc deficiency, iron deficiency and magnesium deficiency, because the phosphate fertilizer will combine with these elements in the soil to reduce their effectiveness. In the absence of potassium, it will be found that the lower old leaves appear scorched from the edge, the fruit is easy to crack, the sugar content is reduced, the flavor is deteriorated, and the plant is prematurely degraded. Therefore, we recommend that the application of fruit fertilization should follow a small number of principles and pay attention to the application of potash. When it is necessary to supplement trace elements, it can be carried out by foliar application.

In addition, as the temperature of the shed rises, sometimes the symptoms of tomato umbilical rot or dry and browning of the top of the cucumber are found. This is caused by calcium deficiency. When the temperature of the shed rises too fast and the temperature changes drastically, it will cause difficulty in water absorption of the plant, affecting the transportation of calcium in the plant, causing calcium deficiency at the top. The solution is to adjust the temperature inside the shed to prevent high and low, timely watering and spraying with calcium on the foliar surface.

As the outdoor temperature rises, the number of viral vectors such as aphids and whitefly increases, and attention should be paid to pest control to reduce the occurrence of viral diseases. Adding insect nets is an effective and economical measure. It should be noted that colorless insect nets are added to all vents in the greenhouse. A disinfectant tank is set at the entrance of the greenhouse, and lime is placed inside for disinfection of the sole. Prepare a bottle of 10% trisodium phosphate or 0.1% potassium permanganate disinfectant in the temperature chamber for the disinfection of the front hand. The control of mites can be sprayed with 25% Aketai 7500-10000 times. All of the above measures can reduce the spread of viral diseases to a certain extent.
