Pumpkin is a vegetable that many people like to eat very much. It tastes sweet and delicious, and there are many varieties. It is an excellent vegetable suitable for all ages, both north and south. However, the temperature in the north is low, and it is generally planted in greenhouses, so there are not so many concerns in the south.
Planting time of pumpkin in greenhouse
Pumpkins are planted in1-March in spring and July-August in autumn, because the temperature and climate at this time are most suitable for pumpkin growth. If you plant pumpkins in the greenhouse, the sowing time can be a little earlier.
Planting pumpkins in greenhouse
1, soil
To plant pumpkins in greenhouses, it is best to choose sandy loam and choose places where pumpkins have not been planted. Apply base fertilizer before sowing, mainly natural organic fertilizer, and then use it after thorough decomposition. In addition, add some compound fertilizers appropriately.
Step 2 sow seeds
Pumpkin seeds need to be exposed to the sun for two days before sowing, and then soaked in warm water for three hours to accelerate germination. After the seeds turn white, they can be planted.
Step 3 raise seedlings
After sowing, keep the temperature at 25-30℃ and control the temperature at night at 12- 15℃. After watering, it should be properly ventilated and planted when the temperature rises and the seedlings have 3-4 real leaves.
Step 4 plant
Before planting pumpkin in greenhouse, apply sufficient organic fertilizer, dig planting holes, plant one plant in each planting hole by deep ditch and high ridge, and pay attention to covering and watering to ensure the rapid growth of seedlings.
Key points of pumpkin management in greenhouse
1, topdressing
Because the fruit of pumpkin is relatively large, in addition to the basic fertilizer in the early stage, topdressing should be carried out when the vine grows to three centimeters, and the second topdressing should be carried out when the fruit grows fast.
2. Pick your heart and flowers
There is one thing to pay attention to when flowering. The first flower is a male flower, which needs to be picked first, and then the female flower grows. During this period, we should pay attention to proper thinning of flowers and concentrate nutrition on pumpkin fruit.
Step 3 build a melon rack
In the process of pumpkin growth, setting the vine length required for growth can effectively improve the fruit setting rate of pumpkin and prevent pumpkin from rotting. Generally speaking, when the vines of pumpkins grow to 3 meters, they need to be put on shelves.
Step 4 remove the yellow leaves
On the melon vines that have blossomed and borne fruit, as long as the melon vines blossom and bear fruit, there will be yellow leaves. If you see it, you should remove it in time, so that you can reduce the consumption of nutrients and let the pumpkin bear more melons.
Step 5 harvest
Honey pumpkins will turn orange when they are ripe, which is the most suitable time for harvesting. Pay attention to handle with care.
