At present, the best-selling varieties on the market are the "short-lived, high-yield king," "Double Happiness," and other varieties. Take these two examples first. Features: pumpkin short vine, red skin, flesh powder, sweet surface, 3.5 cm thick, orange, single plant can be 2-4 melons at the same time, single melon weight 1-1.5 kg; early maturity, easy fruit setting, wide adaptability The per mu is 3000-4000 kg.
The cultivation points are as follows:
First, nursery: Baoding, Langfang city vegetable nursery time should be in the middle of March each year, using small sunny shed and greenhouse nursery.
1. Use nursery medium to raise seedlings: The nursery medium is loaded into a 10 cm 10 cm nutrient bowl, and it is discharged neatly within the impotence (the impotence requires a basic level at the bottom so that the watering is even and the emergence is neat).
2. Seeding: In order to break the dormancy of the seeds and make the seeds germinate neatly, soak the seeds for two days before sowing, then soak the seeds with warm water of 50°C, soak the seeds for 4-5 hours after the water temperature is naturally lowered, so that the seeds will absorb enough moisture. In Yangshuo, which is a good source of nutrients, soaked bottom water before planting. When the water is completely infiltrated, pick a 1-cm deep pit in each nutrient bowl to be sown with 1 cm wide bamboo pieces. The seed is placed flat in the pit and covered with a sieve of fine earth 1.5 cm thick.
3. Miao Miao Management: Miao Miao must have rain-proof facilities before the emergence of the seed, and should not allow the rainwater to directly wash the seedlings. When the seedlings are flush, they spray one fungicide to prevent devastating disease. The seedling age can be planted in 15 days, spraying fungicide and insecticide before planting, plus phytonutrients. The best conditions for the establishment of pest control network pest control.
Second, colonization: seedling age one month, every year in mid-April colonization.
1. Fertilization for soil preparation: Leveling the ground to fineness, apply 2 cubic meters of organic fertilizer and 30 kg of compound fertilizer per acre. If the land is thinner than the ridge, increase the amount of organic fertilizer applied.
2. Colonization: Planting at a spacing of 0.5 m and 1.1 m, 1200 plants per mu. Plant water immediately after planting and cover the mulch.
Third, after the planting management:
1 single vine pruning: leaving the main vine, all the side branches destroyed in order to reduce the consumption of nutrients.
2. Flowering management: When the female flower is open, if the male flower is less open or the bees are less, artificial pollination should be performed in time by gently wiping the female styling with the male flower that is open on the same day. Artificial pollination must be completed before 8 am because the higher the temperature, the weaker the pollen activity. Can also be treated with hormones, the preparation of a good set of fruit geranium decorated with a brush or sprayed with a small watering can, this method should pay attention to the concentration of hormones must be appropriate, the temperature of high concentrations of hormones to be low, low temperature hormone concentration ratio To be high, otherwise prone to malformation.
3 seat melon period management: the main vines melon, root melon timely removal, leaving the second or third melon, knot melon section can not be too far. According to the growth of the dumplings, leave one melon or two melons, and leave 4-5 leaves after the melons to facilitate the nutrient concentrate supply of fruit enlargement. After sitting in the melon, timely dressing and watering are needed to promote fruit enlargement. Nitrogen is the main fertilizer in the early stage of the topdressing, and phosphorus and potash fertilizers are mainly used in the later stage to keep the plants growing and prevent premature aging.
Fourth, timely harvest: generally late May to early June into the harvest period. Timely harvesting to harvest old melons.
It is important to note that planting should be done early to avoid the appearance of flowers. From the seedling stage, attention should be paid to the prevention and control of viral diseases, and the control of aphids and whitefly (the main vector for the spread of viral diseases) should also be prevented. After sitting on the melon, the nutrient is concentrated and transported to the fruit, the leaves gradually age, and the stress resistance gradually declines. At this time, attention should be paid to the control of powdery mildew, downy mildew, aphids, and whitefly, and foliar fertilizers and phytonutrients must be sprayed. Increase leaf resistance and photosynthesis, ensure the normal growth of melons and fruits, and increase yield.
