Master these high-yield pumpkin planting tips to double your profits!

Pumpkin, also known as pumpkin, pumpkin and pumpkin, is an "alien species" introduced into China in the Ming Dynasty, and now it is widely cultivated in the north and south of our country. Here are a few high-yield pumpkin planting tips, master to double your profits!

I. Open-air cultivation

1. The suitable sowing time in different areas should be determined according to local climatic conditions, seedling facilities, cultivation methods, planting period and market demand. The sowing rate should be determined according to the seed germination rate, seed purity, planting density and other conditions.

two。 The seedling age is generally 20-25 days and has 2-3 true leaves; under protected cultivation, the seedling age is about 30 days, and the seedlings have 3-4 true leaves at this time. The standard of strong seedling: the seedling age is 25-35 days, the plant height is about 10 cm, the stem diameter is 0.4-0.5 cm, and there are 3 true leaves.

3. Pumpkin is not strict with soil, and sandy loam and loam are the most suitable. Before sowing, the cultivated pumpkin should be turned deeply and applied circle fertilizer as base fertilizer, generally 2500-4000 kg per mu.

4. Pumpkin cultivation can be seedling transplanting, can also be direct seeding. Due to the great differences in climate in different parts of our country, the planting time of pumpkin is also different. as long as it can ensure that pumpkin seedlings are not damaged by low temperature and freezing, normal growth can be planted or direct seeded.

5. Combined with weeding, intermediate ploughing is carried out from shallow to deep. Be careful not to move seedlings or hurt seedlings or roots when weeding. In order to promote the development of root system, it is necessary to cultivate soil on the root when ploughing. During the whole growth period of pumpkin, it is generally necessary to carry out intertillage and weeding for 2 or 3 times.

6. Pumpkin planting generally does not need irrigation, should be ploughed many times, at the same time, increase the soil temperature, promote root development, in order to strengthen seedlings. After vine extension, 500-1000 kg of rotten manure or 15-20 kg of available nitrogen fertilizer can be applied per mu, and irrigation should be applied after fertilization to prevent root burning with available nitrogen fertilizer. Fertilizer topdressing should be applied less and diligently, and attention should be paid to prevent root burning and fertilizer damage after fertilizer.

7. Generally speaking, there are no more than 3 or 4 lateral vines in pumpkins, and 3 are the best. If there are special cultivation needs, pruning and vines should be carried out according to the needs. Artificial pollination or bee-assisted pollination can be carried out, but it should be done before 9 o'clock in the morning.

8. Pumpkin diseases are mainly powdery mildew and virus. The occurrence of the disease directly affects the growth and development of pumpkin, shortening the growth period, reducing the yield and reducing the quality. Aphids are the main body of the transmission of virus diseases, so if we want to control virus diseases, we must first treat aphids and then control them. Pumpkin powder symptoms: the disease mainly infects leaves, but also damage stems and petioles, generally not harmful fruit. At the beginning of the disease, small white powder spots appeared on the front or back of the leaves, and then gradually expanded into continuous white spots with inconspicuous edges, which seemed to be sprinkled with a layer of white powder, which seriously led to the withering and yellowing of the leaves.

II. Cultivation in greenhouse

1. The yield per mu of pumpkin is about 5000 jin. If the yield per mu can reach more than 6000 jin, it belongs to high yield. Growers using this parallel technology can double the yield of pumpkin and greatly improve the quality of pumpkin. The pumpkin multi-plant parallel grafting technique is to combine the main vines of two or more pumpkins together to grow a new pumpkin main vine, so that there will be multiple pumpkin roots to provide nutrients.

two。 Digging holes about 10 days before planting pumpkin, the size and depth of pumpkin holes must be 1-2 times that of conventional pumpkin cultivation. More organic fertilizer was applied in the pumpkin hole, and phosphorus and potassium fertilizer were added. After mixing the fertilizer soil evenly, the cover soil filled the pumpkin hole, making it slightly higher than the ground. 2-4 pumpkin seedlings were planted in each hole.

3. When the main vine of pumpkin seedlings grows to 60 cm long, it will be merged. First, cut off the tips of the main vines of the two adjacent pumpkin seedlings with a sharp knife, the cut pumpkin sections should be relative and consistent, the shape and size should be basically the same, and then the two pumpkin sections should be closed and fastened tightly. at the same time, wipe off the lateral vines and buds on the lower plants of the pumpkin interface. After 2-3 days, the pumpkin interface can merge and grow new vines.

4. The long vine grows at the interface of the pumpkin, it is only a long vine does not blossom, must be removed in time. The difference between the long vine and the new main vine is that the long vine is located under the interface of the pumpkin and grows rapidly, growing more than 10 centimeters a day; the new main vine (melon vine) grows on the back of the pumpkin and interface, growing slowly but stout.

5. The bud point on the back of the cut should be protected when cutting and joining the main vine, and it should be carried out after 5: 00 p. M. on a cloudy or sunny day. Within 2 days, do not water and wash the interface to prevent the straps from loosening or falling off. In addition, in the growth process of pumpkin after grafting, we should pay attention to applying more phosphorus and potassium fertilizer and less nitrogen fertilizer. If pumpkin is planted in protected areas such as solar greenhouse, the yield-increasing effect of pumpkin is more significant if carbon dioxide gas fertilizer is applied during the flowering and fruiting period of pumpkin.

The above are a few tips on the high yield of pumpkin cultivated in the open air and greenhouse, hoping to be helpful to the majority of growers!
