Pumpkin is a good thing, the food value is extremely high, it can protect our stomach and mucous membranes and eliminate carcinogens, which is in line with the health pursuit of contemporary people. So how do you choose a pumpkin? How to water it? Let's take a brief look at the following and Xiaobian.
First, the variety selection
(1) Red chestnut king
This variety belongs to the early maturing hybrid generation, with good fruit setting, high-quality palate, and wide adaptability. The average yield is about two kilograms per mu.
(2) Gan Li Wang
Gan Li Wang is resistant to heat and fruit development period is generally about forty days, the meat is tight and the taste is good.
Second, soil preparation and fertilization
The root system of pumpkin is very developed, so it has strong ability to absorb fertilizer and needs deep cultivation. The pumpkin planting plot should be selected in a place with good drainage and irrigation conditions. It should be ploughed once every 15 days before planting, and 3000-4000 kg of decomposed organic fertilizer can be mixed per mu.
Third, nursery
Before sowing, the seeds should be fully dried, and then soaked in warm water of 55 degrees Celsius. The optimum temperature for emergence is generally 25 to 30 degrees Celsius. In good weather, two or three days will emerge.
Fourth, colonization
If it is cultivated in the open field, when the pumpkin seedlings grow two or three true leaves, they will be planted without any damage such as frost. Generally, it is recommended to plant in a sunny afternoon. Before planting, attention should be paid to the nutrient seedlings to pour water, which can increase the survival rate.
Five, pruning
Seven days to ten days after planting, when the pumpkin seeds grow to about 30cm, leave two strong vines, and the rest of the vines are cut. Note that the two remaining vines are arranged in the same direction to avoid overlapping.
Sixth, pollination fruit
In general, it is best to have two vines at the same time. Pumpkin male and female flowers usually bloom at 4 am in the morning on a sunny day, and it is not easy to be fertilized after 9:00. In the open field cultivation, if you encounter rainy weather, you can bag the female flower corolla that will bloom in the morning of the previous day.
Seven, fertilizer management
Pumpkins have strong ability to absorb fertilizer, but they should not be applied too much in the early stage, especially nitrogen fertilizer, otherwise it will affect fruit setting. Top dressing is generally carried out twice, the first time after the start of pruning, the second time after the fruit set.
Eight, pest control
In spring cultivation, the main diseases are virus disease, powdery mildew, epidemic disease and downy mildew. The main prevention and treatment of viral diseases lies in the disinfection of seeds and the prevention of the spread of aphids. In case of disease, the diseased plants are removed in time to avoid the spread of diseases. Diseases such as powdery mildew are mainly caused by high humidity. Therefore, we must take the prevention as the main and prevent the combination. Generally, sorghum cultivation should be adopted to reduce the humidity in the field, and it is used alternately with 70% thiophanate 1000 times solution and 75% dysen manganese zinc 700 times solution. Generally, it is sprayed once every 7 days. In case of rain, it should be sprayed in time.
The main pests are yellow squash, aphids and small tigers. Pests mainly harm pumpkin seedlings. After planting, they should cover the mulch in time, and spray with trichlorfon, cockroach, quick-killing and killing. Generally, the spray is sprayed once every 3-5 days.
Nine, harvested
In the harvest period, if picking the tender melon, it is within ten to fifteen days after the flower, the old ripe melon is harvested within forty days after the flower. It is recommended that the first picking tender will be rushed to the morning market, the second batch will be harvested after being cooked, placed in a ventilated place, and can be stored for about 3 months.
