Morphological characteristics of annual climbing herbs; The stems and branches are wrinkled and mucilaginous villous, and gradually fall off when they are old, becoming almost hairless. The petiole is slender, with a length of16-20cm, the indumentum is the same as that of the stem, and there are two glands at the top. Leaf blade is ovate, heart-shaped or kidney-shaped, with length and width of 10-35cm, undivided or 3-5-lobed, 5-7 palmately veined, with sharp apex, irregular teeth on the edge, heart-shaped base, curved and notched, semicircular or nearly round, deep 1-3cm, 2-6cm wide, and puberulent on both sides. Tendrils are slender, puberulent at first, and then gradually fall off, becoming smooth and hairless, and the upper part is bifurcated. Monoecious, female flowers and male flowers are solitary. Male flowers: pedicels are thin, slightly longer than petioles, and pedicels, calyx and corolla are puberulent; Calyx tube funnelform, about 2 cm long, lobes lanceolate, 5 mm long; Corolla yellow, lobes wrinkled, 3-4 cm long, 2-3 cm wide, tip emarginate, 5 veins; Stamens 3, filaments 3-4 mm long, anthers 8- 10 mm long, rectangular, anthers folded. Pedicels of female flowers are slightly shorter or almost as long as petioles; Calyx and corolla are like male flowers; Calyx tube 2-3 mm long; Ovary is thin in the middle, densely sticky villous, short and thick style, 3 stigmas, swollen, 2-lobed. The fruit is green at first, and then turns from white to yellow. Due to long-term cultivation, the shape of fruits varies greatly, and varies from variety to variety. Some are bell-shaped, narrow in the middle and swollen up and down. The upper part is larger than the lower part, and it is several tens of centimeters long. Some are only 10 cm long (small gourd), and some are oblate, rod-shaped or structural. When they mature, the skin becomes woody. The seeds are white, obovate or triangular, truncated at the top or 2-toothed, sparsely round, about 20 mm long. It blooms in summer and bears fruit in autumn.

The distribution of zucchini originated in the tropical region of Eurasia, and has been cultivated in various places for ornamental or medicinal purposes.

The growing environment likes warm, humid and sunny environment, and is not cold-resistant. Neutral loam requires fertile, moist and well-drained soil, and can also adapt to slightly acidic and slightly alkaline soil.

The breeding method is sowing and breeding. Sowing in April, direct seeding or transplanting after sowing, and planting when there are 5-6 real leaves. Before flowering, the core can be removed to promote branching. Need to build a framework for climbing. Fertilize frequently during the growth process.

Cultivation techniques: watering and fertilizing: when sowing, the flowerpot should be of moderate size, loose acidic soil should be selected and mixed with soil miscellaneous fertilizer, and the soil should be well ventilated and drained.

Potted plants are easy to dry up. When the branches and vines are just unfolding, water them 1 time a day. In hot summer, water it twice. After the gourd is diluted with fermented sesame sauce residue and bean cake in the growth period, it is fertilized while watering; Phosphorus and potassium fertilizer should be applied in bud stage to improve fruit setting rate and fruit quality.

Shaping and pruning: gourd has the characteristics of lateral branches bearing fruit. When the plant grows to about 1 m, top it 3-4 nodes away from the root and pinch off the buds in time.

Pollination: Gourd is a cross-pollinated plant, and pollination at flowering stage is the key to fruit setting. Potted gourds must be artificially pollinated. ?

Pay attention to the ventilation in the pest control room; Cut off the diseased leaves in time; Do not reuse basin soil; It was found that aphids could be smeared with soapy water or sprayed with tobacco water of 1: 50 continuously.

The main value of gourd homonym is "Fulu", which is one of the oldest mascots of the Chinese nation. Many countries and nationalities in the world have a history of planting and making gourds, which are widely used in different fields at home and abroad. Gourd can not only be eaten, but also be used as a container.

Among the natural containers endowed by nature, only Cucurbitaceae has such properties. As a kind of food and container, gourd application, gourd technology and gourd culture have been deeply rooted in the long river of human development.

Gourd has developed from the initial container to modern folk handicrafts, and its processing technology is also constantly innovating and developing. Xu Haoran introduced that gourd technology is generally divided into two categories, one is the process of planting and growing the gourd itself, and the other is the processing technology that makes it a handicraft. Among them, gourd processing is a special process, which mainly includes cutting, carving, pyrography, lacquer art and so on.
