What are the planting techniques of pumpkins in spring? What are the methods of high yield management?

As an annual trailing herb, pumpkin can not only be used as a vegetable, but also can replace grain, and all parts of the plant can be used as medicine, so it has great economic value and planting value. What are the planting techniques of pumpkins in spring? What are the methods of high yield management?

What are the planting techniques of pumpkins in spring

1. Sowing seeds

On demand: 2-3 seeds per hole, seed tip facing down, covering soil 2-3 cm, watering thoroughly, germinating at 25-30 ℃ for about 1-2 weeks.

Direct seeding: you can prepare the ground in the winter of the first year and apply enough base fertilizer, and then bury the seeds in February and March of the second year. Because the seedlings grow long and grow fast, you need to apply fertilizer in April, May and June, and pay attention to watering. Pumpkin management is relatively extensive, because the root system is developed, leaf internodes take root, so we should pay attention to soil cultivation in order to absorb nutrients. A pumpkin can produce many branches, in order not to disperse nutrients too much, to fork, a seedling leaves 2-3 main vines, and according to the soil fertility and seedling growth, after several births can hit the top bud. Pumpkin as long as the fertile soil, frequent watering and fertilization, generally 3-5 leaves slip a melon, leaving more melons will not grow up. Melon axils are very easy to branch buds, we should pay attention to remove, otherwise compete with melons for nutrients, so that melons lack nutrients and wither and fall.

2. Fixed value

When there are 3-5 true leaves, strong, disease-free and pest-free seedlings can be selected for colonization in the sunny afternoon, with 1 plant in each pot. the planting depth should be cotyledon flat soil surface and watered thoroughly. If it is direct seeding, it is necessary to remove the sick seedlings and leave 1 seedling in each hole.

II. Measures for high yield management of pumpkin

1. Pick the heart

When the pumpkin vine grows to about 2 meters, it is necessary to pick the growing point of the main vine, so that the main vine grows into a branch vine and promotes the vine to blossom and bear fruit.

2. Build a melon rack

When the vine of the melon vine grows to 3 meters, it is necessary to draw the vine on the shelf, the pumpkin fruit is relatively large and heavy, and choose this bracket to bear the weight of the pumpkin, which can effectively improve the melon sitting rate, and the important thing is that the melon will not rot.

3. Spray up and down

Due to the large size of pumpkin, it is necessary to do a good job in topdressing management and improve yield and quality in the fruiting stage, while spraying foliar fertilizer and root forest fertilizer can be used in topdressing. As a result, pumpkins should be sprayed with foliar fertilizer every 10 days. at the same time, organic flushing fertilizer on the roots can make pumpkin vines grow more prosperous.

4. Auxiliary pollination

When the pollinated female flower is about to open, it needs to be covered with melon leaves, and between 8: 00 and 9: 00 the next morning, the abnormal male flower will be picked over the female flower, and it can be removed after pollination.

5. Remove the yellow leaves

On the vines that have already blossomed and bear fruit, generally, as long as the vines blossom and bear fruit, they will have yellow leaves, such as they should be removed in time, so as to reduce the consumption of nutrients, so that pumpkins will bear more melons and increase pumpkin yield.

6. Prevent overgrowth

Melon vine growth will lead to a decrease in the number of pumpkin, so it is necessary to prevent melon vine growth, but also the right amount of control nitrogen fertilizer, increase phosphorus and potassium fertilizer. Can be in the root of the melon vine 30 cm, with a knife in the middle of a small cut, and then plug a small piece of charcoal in the mouth, so that you can control the excessive growth of the melon vine.

I believe that you have a more comprehensive understanding of pumpkin planting methods, if farmers want to grow high-yielding pumpkins, these methods are very good.
