Morphological characteristics of Pumpkin

Pumpkins are trailing herbs of the year. Mostly oval, and long, round, stem several meters long, node rooting, sturdy, furrowed, hispidulous, tendrils divided into 3-4 forks. Simple leaves alternate, leaf blade cordate or broadly ovate, 5-lobed with 5 angles, slightly soft, about 15-30 cm long, both sides densely fluffy, margin irregularly serrated, often white spots along margin and leaf surface.

Triangular, densely covered with yellow-white bristles and hairs, often with white spots, leaf veins raised, the veins of each lobe often extend to the top, into a small tip, the back color is lighter, the hair is more obvious, the edge has small and dense fine teeth, the top is slightly obtuse. Tendrils slightly stout, as shortly setose and velutinous as petioles, 3-5-branched.

Fruiting pedicel stout, angled and grooved, 5-7 cm long, pedicel enlarged into trumpet-shaped. The shape of bottle gourd varies from variety to breed, and there are often several longitudinal grooves or none on the outside. Seeds numerous, long-ovate or oblong, gray-white, margin thin, 10-15 mm long and 7-10 mm wide. Like orange petal, ranging from orange-yellow to orange-red. The fruit stalk is furrowed and the melon stalk expands into a trumpet. Seeds ovate or elliptic, 1.5 × 2 cm long, grayish white or yellowish white, margin thin. The flowering period is from May to July and the fruiting period is from July to September.

Unisexual flowers, monoecious. The male flower receptacle is short. Calyx lobes linear, apex enlarged into leaflike. Corolla campanulate, yellow, 5-lobed, lobes spreading, rugose. There are 3 stamens. Anthers conjunct, anther chamber regular S-shaped curvature.

What about pumpkins?

The reason why pumpkins turn into melons:

The phenomenon that pumpkins die when they grow to the size of their fists is called melons. At present, the main causes of alpine pumpkin are: (1) the recent high temperature is not conducive to pumpkin fruit setting and fruit expansion, resulting in melon. (2) too much fertilizer and water, especially after pumpkin harvest, the pruning can not keep up with it, which will often cause pumpkin vines to grow too vigorously and plants to grow excessively, which can easily lead to melons. (3) Diseases and pests can also cause pumpkins to turn into melons.

Preventive measures to turn pumpkins into melons:

First of all, it is necessary to do a good job in resisting high temperature and drought.

Secondly, according to the growth situation of pumpkin, corresponding cultivation and management measures should be taken. For example, for overgrowing plants, it is necessary to properly control fertilizer and water, strengthen pollination, pruning and other management measures, erase too many lateral vines, promote female flowers on the main vines to set fruit, and control overgrowth; for weaker plants, it is necessary to strengthen fertilizer and water management to promote fruit expansion. For plants harmed by diseases and insect pests, it is necessary to prescribe the right medicine for aphids. Aphids can be sprayed with imidacloprid, rehabilitation, insecticides, and at the same time, virus diseases transmitted by aphids should be well controlled. Powdery mildew can be controlled with Fuxing, Fenruining, Shigao, etc.; disinfected plants with blight should be pulled out in time and disinfected with lime, and then all plants should be irrigated with Guakuning and other chemicals to prevent them.
