Watermelon is the nickname of pumpkin, planting methods are as follows:

1, land fertilization: pumpkin's root system is very developed, so the ability to absorb fertilizer, the need for deep plowing. Pumpkin planting plots should be selected where drainage and irrigation conditions are good, fifteen days before planting ploughing once per acre can be mixed and applied 3000-4000 kg of rotted organic fertilizer.

2, seedling: seeds should be fully dried before sowing, and then soaked in warm water at 55 degrees Celsius, the most suitable temperature for seedlings is generally 25-30 degrees Celsius, the weather is good, two or three days will be seedlings.

3, planting: If open field cultivation, when the pumpkin seedlings grow two to three true leaves, and no frost and other hazards when planting. Generally choose the weather clear afternoon planting, planting before the attention of the nutrient bowl seedlings to water thoroughly, can improve the survival rate.

4, the whole branch: seven days after planting to ten days, such as pumpkin trails grow to 30cm or so, leaving two strong trails can be, the rest of the trails all cut off. Note that the two left behind should be arranged in the same direction, to avoid overlapping.

5, pollination fruit: generally speaking, it is best to make two vines at the same time fruit. Pumpkin male and female flowers generally in the morning of sunny days at four o'clock in the morning, after nine o'clock is not easy to fertilize. Open field cultivation, if encountered rainy weather, can be in the morning of the previous day will be flowering female flower corolla bag.

6, fertilizer management: pumpkin fertilizer absorption capacity, but in the early stage of the base fertilizer can not be too much, especially nitrogen fertilizer, otherwise it affects the fruit. Fertilizer is generally divided into two times, the first time in the beginning of the whole branch, the second time is after the fruit.

7, harvesting: to the harvesting period, if it is picking young melon, it is ten to fifteen days after the flower, the old ripe melon in the forty days after the flower harvesting. It is recommended that the first picking young hanging early to market, the second batch, mature harvest, put in a ventilated place, can be stored for about 3 months on the market.

Pumpkin disease control

1, powdery mildew: white mold spots appear on the leaves or young stems of the victim, and in severe cases, the whole leaf is covered with white powder. The disease can be prevented by using 70% powdery mildew 700%. You can use 70% powder rust 700 times dilution, or sulfur suspension 250 times dilution, or 50% carbendazim 500 times dilution, or 500 times dilution, or sulfur gum suspension 250 times dilution, or chlorothalonil 600 times dilution, or be used to force 700 times dilution to prevent and control, cross use, and spray 3-4 times.

2, virus disease: the affected plants leaf surface yellow spots or shades of mottled foliage, foliage appears bumpy, stem and top leaves twisted. Can use 20% virus A or virus one 500 times dilution, or 1.5% phytophthora emulsion 1000 times dilution, or mycotoxin 400 times dilution, or 83 pitcher 100 times dilution, or mycotoxin 600 times dilution, every 7-10 days to spray 1, sprayed 3 times.

3, spot disease: the victim plant leaf spots round to nearly round, high humidity spot surface densely small black dots, serious spot fusion, resulting in localized leaf death. You can use 70% Tolbutrazine 800 times diluted solution, or 50% of Porphyrin 1500 times diluted solution, or 75% Chlorothalonil 800 times diluted solution, or sulfur suspension 500 times diluted solution, or Bidely 600 times diluted solution to prevent and control the disease, every half a month 1 time, and sprayed 2 times.
