How should pumpkins be fertilized during cultivation to grow better?
What is the best way to fertilize pumpkins? Please give a detailed introduction. For growing pumpkins, you can refer to the following fertilization methods: apply a heavy base fertilizer and transplant at the right time: pumpkins have a well-developed root system and strong nutrient uptake capacity, so deep plow 30 cm before winter, and plow a second time the following spring. Apply 75000 kg of fully decomposed high-quality organic fertilizer per hectare, broadcasting it before the second plowing or applying it in a concentrated way within the sowing beds. After plowing and leveling, make sowing beds or transplanting beds, and transplant about 4500 plants per hectare.

After pumpkin transplanting and seedling recovery, if the seedlings are weak and the leaves are pale and yellowing, you can apply a vine-growing fertilizer together with watering, applying 3750-4500 kg of diluted manure water per hectare. When the plants enter the mid-growth stage and 1-2 young fruits have set, a heavy fruit-promoting fertilizer should be applied before the rows close, generally 15000-22500 kg of decomposed diluted manure water or cake fertilizer water per hectare. If it is dry during this period, you can combine it with watering and apply 225-300 kg/ha of compound fertilizer by flushing with the water. After the fruits begin to be harvested, to prevent premature aging of the plants and increase later yields, a small amount of organic fertilizer can also be applied. If you are not harvesting tender pumpkins but mainly plan to harvest mature pumpkins, there is no need to apply additional fertilizer later; just pay attention to watering or drainage. In the middle and late stages, you can also spray 0.2%-0.3% monopotassium phosphate, once every 7-10 days, for 2-3 consecutive sprays.
Pumpkins like organic fertilizers, and the amount of fertilizer and nutrient combination should be determined according to plant growth and soil fertility. If the growing point of the vine is thick and upturned and the leaves are dark green, fertilizer should not be applied, to prevent excessive vegetative growth and fruit abortion; if the leaves are light green or yellowing, fertilizer should be applied promptly.
