Causes of “pot belly†melons Caused by bad pollination In the pollination period of cucumber flowering, due to dry climate or too much rain, female flowers failed to fertilize sufficiently. Cucumbers were fertilized at first and seeded and expanded, and fertilization at the back was poor, and seeds could not be formed. Belly waist" cucumber.
The uneven water supply during the period of nectarine was uneven, and the drought and drought occurred during the period of pods, especially in the early stage of cucumber growth and later in the rain, and it was easy to form a "pot belly" melon.
Fertilizer imbalance in the base fertilizer and topdressing application of nitrogen fertilizer is too much, the amount of potash fertilizer is insufficient, the formation of cucumber absorption of nitrogen fertilizer is more, absorption of potassium is less, "dot" melon increased.
Effective measures for prevention
1, artificial pollination in the melon period in case of continuous rain, artificially assisted pollination, so that female flowers fully fertilized, to ensure good fertilization, to avoid the "bellied" melon.
2. To balance the water supply with drought, water the soil in a timely manner to keep the soil moist and avoid excessive drought. Whenever there is a heavy rain or continuous rain, it should be immediately drained and put to rest to maintain the balance of water and reduce the occurrence of “big belly†melons.
3. Potassium fertilizers are mainly used for timely potassium supplementation, supplemented by nitrogen fertilizers. In case of rainy days during fruiting period, potassium sulfate, arbor, and other available potassium fertilizers should be topdressed, and 0.3% potassium dihydrogen phosphate solution can also be sprayed on the leaves. Increase plant potassium levels and reduce the "pot belly" melon.
