Pumpkin is a plant of the genus Cucurbitaceae. It is widely cultivated in various parts of my country. It has strong adaptability and is resistant to storage and transportation. It is one of the main vegetables in summer and autumn. Both young and old pumpkins are edible and rich in nutrients. It is an excellent health vegetable and is very popular among consumers.

1. Variety

Pumpkin is widely cultivated in my country. Common cultivars can be divided into three types in botany: common pumpkin (Chinese pumpkin), winter squash (Indian pumpkin) and zucchini (American pumpkin). The main cultivars in the south are:

①Candied Date Pumpkin: bred by the Institute of Economic Crops of Guangdong Academy of Agricultural and Forestry Sciences. It has strong branching ability, papaya-like shape, dark longitudinal grooves, dark green skin, with small yellowish-white spots, and turns earthy yellow when mature. The flesh is nearly solid, of excellent quality, and has market prospects. A single pumpkin weighs 1.5 kg.

② Pillow pumpkin: The pumpkin is short and cylindrical, thinner in the middle, with warty protrusions on the surface. The young pumpkin is dark green, and turns yellow when ripe, with net patterns and spots. The flesh is coarse and sweet. A single pumpkin weighs about 4 kg and is resistant to storage and transportation.

③ Large Grinding Pan Pumpkin: The pumpkin is oblate, and when mature, the skin turns yellow with white powder on it, the flesh is orange-red, thick and fine, and tastes sweet. People mainly eat mature pumpkins, and a single pumpkin weighs about 10 kilograms, and is more resistant to storage and transportation.

④ Foot-plate pumpkin: A local variety in Guangxi, it has strong branching ability, the pumpkin is oblate, with several ridges on the surface and a sunken navel. The young pumpkin is green with white spots, while the old pumpkin is orange-red with yellow spots. The pumpkin flesh is delicate and firm, sweet, and resistant to heat, storage and transportation. A single pumpkin weighs 7.5 kg, and a large one can reach more than 20 kg.

2. Cultivation techniques

Pumpkin is a warm-loving, short-day plant with strong drought tolerance. It is not very demanding on soil, but fertile, neutral or slightly acidic sandy loam is preferred. Spring sowing of pumpkin is from late February to early April, and off-season cultivation is sown from July to August.

Select plots or hillsides with convenient drainage and irrigation and deep soil, build piers of 1.5 meters by 3 meters and 1 meter high, build 150 piers per 667 square meters, apply 3,000 kg of farmyard manure and 50 kg of vegetable formula fertilizer, dig holes and apply deeply, mix with mud and cover with soil, then plant or sow 3-4 seeds near the edge of the hole. You can also build piers and interplant in the space of the newly planted orchard.

3. Field management

After the plants are pruned, they should be topped when they grow to 7-10 leaves, leaving 3-4 side vines. Generally, the vines should be pressed after 3-5 leaves. When the male and female flowers are in bloom, they should be artificially pollinated at 6-7 am every morning, pollinating 3-4 female flowers, and selecting 2-3 melons per vine, and the rest should be removed as soon as possible. After leaving the melons, top them at 5-7 leaves away from the melons, and remove the side branches as soon as possible. Generally, no watering is done before the melons are set. After the melons are set, water them 3-4 times according to the soil moisture and soil fertility. Apply 20 kg of compound fertilizer per 667 square meters each time, or 30 kg of bean bran mixed with 2 kg of phosphate fertilizer and 2 kg of biological potassium.

4. Disease and pest control

① Powdery mildew: When affected, white mildew appears on leaves or tender stems. In severe cases, the entire leaf is covered with white powder. You can use 70% triadimefon diluted 700 times, or sulfur suspension diluted 250 times, or 50% carbendazim diluted 500 times, or thiophanate-methyl diluted 500 times, or sulfur gum suspension diluted 250 times, or thiophanate-methyl diluted 600 times, or Betril diluted 700 times for prevention and control. Use alternately and spray 3-4 times in a row.

② Virus disease: The affected plants have yellow spots or mottled leaves with different shades, uneven leaves, and twisted stems and top leaves. You can use 20% Virus A or Virus No. 1 diluted 500 times, or 1.5% Plant Disease Emulsion diluted 1000 times, or Junduqing diluted 400 times, or 83 Zengkeng Agent diluted 100 times, or Junduning diluted 600 times, spray once every 7-10 days, and spray 3 times in a row.

③ Spot disease: The leaf spots of the affected plants are circular or nearly circular. When the humidity is high, the spots are densely covered with small black spots. In severe cases, the spots merge, causing partial death of leaves. You can use 800 times dilution of 70% thiophanate, 1,500 times dilution of 50% chlorhexidine, 800 times dilution of 75% chlorothalonil, 500 times dilution of sulfur suspension, or 600 times dilution of Beta-Dry for prevention and control. Spray once every half a month for 2 times in a row.

④ Pests: mainly aphids, yellow worms, melon flies, armyworms and other pests. They can be controlled by using anthelmintic acid and dimethoate or pyrethroid pesticides.

5. Harvesting and storage

Pumpkins can be harvested as young or mature. It is better to harvest young melons that are harvested early, so that the young melons that grow later have sufficient nutrition and grow well. It is best to harvest young melons 10-15 days after the flowers have faded. Mature melons are harvested 35-60 days after the flowers have faded. Young melons should be sold as soon as they are harvested. Old melons should be harvested when they are fully mature, with thick wax powder on the skin, can not be scratched, and the skin color turns yellow. For pumpkins to be stored, the vines about 5-10 cm long on the stem should be cut off. It is advisable to choose mature, undamaged, disease-free and insect-free live vine melons, and be careful to handle them with care. It is best to harvest them in the morning after a few days of clear weather. Storage should be in a ventilated and cool place, with wooden boards as the bottom, and single-layer stacking or layered storage on racks. Rotten melons should be picked out in time. Generally, they can be stored for 3-6 months and can be continuously supplied to the market.
