Pumpkin is an annual vine herbaceous plant of Cucurbitaceae Cucurbita, is one of the important vegetables in China, can be used as food for preparing food, and can be used as medicine for all parts of the plant, the seed contains pumpkin seed amino acid, and has the effects of clearing heat, removing dampness, expelling parasites, controlling and killing schistosome, the vine has the effect of clearing heat, and the pedicellus melo has the effect of preventing abortion, and can radically cure toothache. The pumpkin cultivation area in China is large, the pumpkin is cultivated in the south and the north, and according to statistics, the sowing area of the pumpkin in China is about 110 kilohm2。
The pumpkin can not germinate when the optimum temperature of the pumpkin in the germination period is 25-30 ℃, and the temperature is below 10 ℃ or above 40 ℃; the suitable temperature in the seedling stage is 23-25 ℃ in the daytime and 13-15 ℃ at night. In production, the pumpkin is generally cultivated by facility seedling, field climbing cultivation or bracket cultivation. Greenhouse in Dongting lake area from 2 to 3 ten days of the monthSeedling culture, transplanting from 3 to 4 ten days of the month, the seedling age is 30-40d, and the seedling cost of the field is 3000-2. As the Dongting lake region belongs to subtropical monsoon climate and is clear in four seasons, the average minimum temperature in 1 month is only about 2 ℃, and the average minimum temperature in 2 months is also only about 4 ℃, which is unfavorable for pumpkin seedling culture. Some people adopt a heat preservation seedling raising mode of a greenhouse and a small arched greenhouse, but the temperature raising effect is limited; some people also adopt electric heating plug seedlings, but various seedling diseases often occur due to multiple times of foliage watering, and uneven watering causes uneven seedling emergence; although the problem of water supply is solved by the common floating seedling raising method for tobacco and other crops, the temperature and the water temperature in spring are low, and the seedling growth is not facilitated. Once the pumpkin seedlings are in the year of continuous low-temperature overcast and rainy in spring, the phenomenon of pumpkin seedling death is common, so that the pumpkin seedlings are in shortage in large area, and the safety risk of conventional seedling raising is great.
