It can be planted twice a year. Because bamboo shoots and melons like heat and can't tolerate low temperature, we usually plant bamboo shoots and melons for transplanting in 165438+ 10, and transplant in May and July in the next year. In the same year, we usually refer to these two time ranges as winter stubble and autumn delay. Sunflower is also known as Indian pumpkin, jade melon and north melon. Cucurbitaceae, Cucurbitaceae. Annual vine herb, with tender melons or seeds as its cultivation purpose. Young melons are suitable for frying, trapping or feeding, and dry seeds can be fried.

Cultivation of bamboo shoots and melons

We need to prepare the greenhouse about one month before the transplanting date. If a new greenhouse is not used, the greenhouse used in the past must be disinfected before the greenhouse is buckled. There are various ways of disinfection and sterilization, which can be selected according to the actual situation of greenhouse. The high yield and habits of bamboo shoots and melons require us to choose calcareous soil layer with rich nutrients, if not rich and high quality soil layer that can be applied immediately.

Organic chemical organic fertilizer should be mainly used, and then a certain amount of chemical fertilizer should be used alone, or enough slag should be infiltrated into the soil layer to ignite, and some gravel should be added in the middle and late stage. Considering the requirements of bamboo shoots and melons that they like humidity and cold, but they like fertilizer but are not tolerant of fertilizer, the water outflow from farmland can be reduced and the soil water content can be maintained. Repeated planting of the same whole farmland must be disinfected once a year.

To raise seedlings, it is necessary to solve the seed problem to the necessary extent before transplanting. Prepare the nutrient soil for the rootstock nursery basin in advance, select qualified bamboo shoots and melons without shrinkage, soak them in warm water at 20-30 degrees Celsius for 4-6 hours, and take them out to dry after the surface of the seeds is cleaned.

When seeds germinate in the natural environment of 20-30 degrees Celsius, most seeds can germinate within two days. When the seed outcrops more than three quarters, it is necessary to start sowing and cover the farmland with plastic film. After the seedlings are unearthed, we can only remove the agricultural film and choose a suitable docking site. When the cotyledons of the seedlings are in progress, the seedlings are butted by grafting, and the seedlings are coded into Miao Di together.

Transplanting, if the time is right, transplanting should be sooner rather than later. As far as possible, it should be set at a time when the seedlings are not easily damaged by ultra-low temperature. The farmland temperature should at least exceed 10 degrees Celsius during the day, and the minimum temperature at night should not be lower than 5 degrees Celsius. Moreover, the transplanted bamboo shoots and melons are best grafted seedlings with one leaf and one meaning, and the grafting time is about half a month.

The seedling surface spacing and height-width ratio should be moderate, with a width of 75 cm, a height of 15 cm and an intermediate spacing of 160 cm at seedling stage. In addition, the seedling row spacing was specified, and the row spacing was 1 10 cm and 30 cm respectively, which was most suitable for the growth and development of bamboo shoots and melons.

In order to ensure high yield and high quality, the relative planting density of bamboo shoots and melon seedlings must be properly controlled. The number of seedlings in 1 mu is about 5000, and the spacing between plants is about 30 cm, so the relative planting density can exceed 1 mu and 3600 plants.
