Measures for increasing yield of Pumpkin cultivation

Pumpkin is a plant of the genus Cucurbitaceae. The term "pumpkin" can specifically refer to Chinese pumpkin (Cucurbita moschata) in the genus pumpkin, and can also generally refer to other cultivated species of pumpkin, including bamboo squash (also known as Indian pumpkin), zucchini (also known as American pumpkin) and so on. Among them, the former is called "North melon" in Changde and other places in Hunan, and it is also called "North melon" in Changde, Hunan Province, and is also called "North melon" in Changde, Hunan Province, and is also called "North melon" in Changde, Hunan and other places.

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. [3] it is like orange petal, ranging from orange 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. Female flowers: Calyx lobed conspicuously, leaflike, ovary orbicular or elliptic, 1-loculed, parietal placenta, style short, stigma 3, 2-lobed each. Bottle gourd, flat ball-shaped, pot-shaped, cylindrical, etc., with longitudinal grooves and protuberances on the surface, smooth or verrucous protuberances.

Measures for increasing yield of Pumpkin cultivation

1. Take the top. When the melon vine grows to 2 meters, pick off the growth point of the main vine, and you can grow 4 branches.

two。 Set up a fight. When the vine grows to 2 meters, lead the vine to the scaffolding and be careful not to break the vine. After building the scaffolding, the pumpkin will greatly reduce the harm of diseases and insect pests, so that the melon sitting rate will be greatly improved.

3. Pollination. Using artificial pollination, the effect of increasing yield is particularly significant.

The method is: cover the soon-to-open and pollinated female flowers with melon leaves to prevent Rain Water from invading. At about 9 o'clock the next morning, pick the male flowers from different plants and cover them over the female flowers, and remove the covered male flowers after 3 days.

4. Pick the leaves. On the flowering and fruiting vines, remove the foot leaves and old yellow leaves in time, and remove 30% of the male flowers, which can not only ventilate and penetrate the light, but also avoid the consumption of nutrients.

5. Bury the stem. In the later stage of pumpkin growth, that is, after knot 2Mel 3 batches of melons, part of the wax yellow leaves were removed from the roots, and the adventitious roots on the vine nodes were buried, which could increase the yield by 30%.

The method is: choose fertile vegetable garden soil mixed with a small amount of organic fertilizer and quick-acting chemical fertilizer, bury 4 Mel 6 stems, to ensure that there is enough length of buried stems, if the length of the stems between the ground and the frame is too short, you can combine to sort out the vines on the shelf surface and retract the main stem part properly, but do not pull or transplant the stems. The soil layer should be buried tightly to facilitate the growth of adventitious roots. At the same time, special attention should be paid to mastering the time of burying stems. Too early, it is easy to cause overgrowth; too late, adventitious root germination and growth is slow.
