Chestnut pumpkin is a new variety of early-maturing pumpkin with small melon type. The fruit is oblate, the peel has longitudinal stripes, and the meat is thick and orange.

Sowing method:

Seeding and seedling raising-in mid-March, seedling raising in greenhouse nutrition pots, each pot 1 grain, chestnut and pumpkin? After sowing, cover the soil by 0.5cm, and cover it with plastic film to keep warm until emergence. The temperature is controlled at 25~30℃, and the temperature is appropriately reduced after emergence, and it is controlled at 20~25℃. Produce more than 600 seedlings per 667 square meters, and control water before planting 1 week to improve the stress resistance of seedlings.

Soil preparation and fertilization-Fertilize and prepare soil in the field before planting. The base fertilizer is 2000 kilograms of high-quality organic fertilizer and 50 kilograms of 25% compound fertilizer per 667 square meters. It is planted in a single row with a height of 3 meters, and the central planting area of the ridge is covered with black plastic film to improve the ground temperature and prevent weeds.

Planting-in mid-April, when the seedlings grow to 5 true leaves, punch holes at the spacing of 45~60cm for planting.

Picking and pruning-using single vine pruning method, the lateral branches should be smoothed in time, and the branches should be arranged without overlapping and staggering. Two vines are used for pruning, the planting density is halved, and coring is carried out when the seedling is 3 years old and leaves are true in the seedbed stage. If the topping is too late, the germination and harvest of the vines will be delayed. When the vines grow to about 20cm, choose two vines with strong and consistent growth, and wipe off the axillary buds below the fruiting nodes (about 8 nodes) of the vines in time. The arrangement of branches and vines in the ridge should be reasonable. For example, when the 1 branch extends to the left of the ridge, the second branch should extend to the right of the ridge, and so on. When the vines grow to about 60cm, you can spread straw and wheat straw.

Topdressing and watering-topdressing twice in the whole growth period, 1 topdressing on both sides of the ridge after fruit setting. The second topdressing should be applied at the top of branches and vines at 1 fruit harvest, and the amount of nitrogen and potassium fertilizer should be 3~4kg each time, and watering should be done in time after each topdressing. Pumpkin has luxuriant branches and leaves, large evaporation, and needs a lot of water during its growth. After planting 1 week, irrigate 1 time slow seedling water to promote the growth of branches and leaves; After fruit setting, water 1 time. In the future, according to the climatic conditions, water properly to ensure the development of fruits. After the fruit is fully ripe, water should be properly controlled to promote the accumulation of dry matter in the fruit and improve the quality of pumpkin.

Fruit setting and adjustment-the 1 fruit setting node of single vine pruning is 15, and the second fruit is about 20 nodes. The 1 fruit node of double vine pruning is 8~ 10, and the second fruit is 15. The specific operation can be adjusted according to the plant growth. Artificial pollination or hormone treatment can improve the fruit-setting rate and flexibly adjust the fruit-setting node position. Young fruit is easy to be injured within 10~ 15 days after fruit setting. Don't move branches and vines around young fruit at this time. In addition, if the fruit is placed directly on the plastic film or on the ground, the skin will turn yellow, which is easy to breed diseases. Therefore, adding a bottom cushion after fruit sitting can avoid the above shortcomings and make the fruit surface uniform in color and beautiful in appearance.

Pest control-The main pests and diseases of chestnut and pumpkin are aphid, spider mite, leaf spot and powdery mildew. Use 800~ 1000 times DDVP emulsion and 1500~2000 times avermectin to control aphids and tetranychus mites. Leaf spot and powdery mildew should be controlled with chlorothalonil and thiophanate-methyl 1000 times solution, and attention should be paid to foliar spraying.

Harvest-After 40-45 days of fruit setting, the chestnut and pumpkin can be harvested when the pulp turns completely yellow and the seeds are full.
