Cultivation techniques of pumpkin

breeding method

Sowing: 2-3 seeds per hole, with the tips of seeds facing down, covered with soil for 2-3 cm, watered and permeable, and germinated at 25-30℃ for about 1-2 weeks.

Live broadcast: In the first winter, you can clean the ground, apply sufficient fertilizer, and bury seeds in the second spring in March. Because the seedlings are long and grow fast, they need to be fertilized in April, May and June, so pay attention to watering. Pumpkin management is relatively extensive, because the root system is developed and the leaves take root between nodes, so we should pay attention to cultivating the soil in order to absorb nutrients. A pumpkin seedling can grow many branches. In order not to make the nutrients too scattered, branches must be made, and two or three main vines should be left in one seedling. According to the soil fertility and the growth of melon seedlings, a few melons can remove the terminal buds. As long as the soil is fertile, water and fertilize pumpkins frequently. Generally, 3 to 5 leaves are used to slide a melon, and if there are more melons, they will not grow up. Buds are very easy to grow in the axils of melons, so we should pay attention to removing them, otherwise they will compete with melons for nutrition and make them fall because of insufficient nutrition. ?

Field planting

When there are 3-5 real leaves, healthy seedlings without pests and diseases can be planted in sunny afternoon, each pot 1 plant, and the planting depth should be that the cotyledons are flush with the soil surface and watered. If it is a live broadcast, it is necessary to sparse the diseased seedlings and leave 1 seedling in each hole. ?

Fertilize soil or land

After planting 10 days, spray thin organic fertilizer 1 time, mainly nitrogen fertilizer. This plant grows rapidly after climbing vines. When there are 8 to 10 true leaves, topping at 1 time will promote more lateral vines to germinate. At this time, support can be set in advance. When the lateral vines are more than 50 cm long, tender shoot tips and petioles can be collected for eating. Pay attention to keep about 5 leaves, and press the remaining stems and vines with slightly larger clods to promote germination and aerial rooting. Spraying 1 times of thin decomposed organic fertilizer with nitrogen fertilizer as the main component after each picking. ?

support

When the vines circle around the basin on the soil surface, they can be dragged to climb the bracket, so that the leaves are evenly distributed and the branches are not shielded from each other. ?

operate

After a certain stage, the plant enters the flowering stage, and the male flowers are the main ones in the early stage. When the flowers are about to bloom in the morning, you can pick the male flowers and pedicels together to eat. When the female flowers begin to grow, the topdressing of organic fertilizer is mainly phosphorus and potassium fertilizer, and the harvesting of tender shoot tips is reduced or stopped. If necessary, artificial pollination must be carried out before 8 am. Usually, 3-5 melons can grow normally per plant (large melons are reserved for 1-2 melons, and the number of miniature melons can be increased appropriately, depending on the plant growth). Too many young melons or female flowers should be thinned out, and the stems and vines should be topped appropriately to avoid insufficient nutrient supply. Larger melons can be hung in a solid place with net bags, and melons close to the ground can be padded with foam plastic or wooden boards to isolate them from the soil. ?

Pumpkin growth process

1. Pumpkin seedling stage: from 1 true leaf to 5 ~ 7 true leaves, the seedling stage is before tendrils appear. Plants grow upright during this period. There were fewer leaves at seedling stage, but the roots began to grow rapidly. At the end of seedling stage, the transverse body of the root is 0.5 ~ 1 m, and the depth is more than 30 cm, and the axillary buds begin to move. This period takes about 25 ~ 30 days at 20 ~ 25℃, and more than 40 days if the temperature is lower than 20℃ and the growth is slow.

2. Pumpkin vine-pulling period: Pumpkin vine-pulling period is from the 5th to 7th true leaves and tendrils to a female flower. It usually takes 10 to 15 days. At this stage, the growth of stems and leaves is accelerated, the internodes are gradually elongated, from upright growth to creeping growth, the tendrils are pulled out, and the male flowers are blooming one after another. At this stage, the nutrition grows vigorously, and the axillary buds on the stem nodes move rapidly, pulling out the lateral vines. At the same time, flower buds also differentiate rapidly. Under low temperature and short sunshine, the node position of female flowers is low.

3. Flowering and fruiting period of pumpkin: It takes 50 ~ 70 days from female flower opening to fruit ripening, and the growth of stems and leaves and flowering and fruiting are carried out at the same time. A female flower appeared in the 5th ~10 node of the early-maturing pumpkin variety, in the 5th ~18 node of the middle-maturing pumpkin variety, and in the 24th node of the late-maturing pumpkin variety. After the female flower appears, it can appear every few paragraphs, or it can appear for several consecutive paragraphs.
