What are the effective methods for ensuring flower and fruit retention in pumpkins?
What methods can ensure flower and fruit retention in pumpkins? Please explain. If too much nitrogen fertilizer is applied in the early growth stage of pumpkins, the plants tend to grow excessively, causing flower and fruit drop, and it becomes impossible to ensure uniform fruit set and the final product quality. Therefore, the amount of nitrogen fertilizer used should be controlled, and the proportion of phosphorus and potassium fertilizers should be appropriately increased. When needed,...

Effective methods to prevent weak seedlings during the oilseed rape seedling-raising period
How can weak seedlings be prevented during oilseed rape seedling raising? Please advise. Because oilseed rape seeds are tiny and have a high germination rate, sowing very easily leads to an excessive seeding rate, overly dense emergence, crowded seedlings, and later deterioration of nutrition, poor growth, weak seedlings with elongated stems, and similar problems. After such rape seedlings are transplanted to the field, they have poor stress resistance, slow green-up, and...

How to fertilize winter melon effectively? A detailed guide to practical methods
Fertilization principles: Winter melon grows best in slightly sandy soil rich in organic matter. It tolerates heavy feeding but not poor, barren soil, and it has comprehensive requirements for nutrients such as nitrogen, phosphorus, potassium and calcium. Basal fertilizer should be applied heavily, with reasonable supplementary fertilization. Nutrient uptake is low at the seedling stage, greater at the bolting stage, and during flowering and fruiting, especially in the early and middle stages of fruit development, uptake is...
