2, cultivation techniques
Soil Improvement: The requirements of the lotus mist on the soil are not strict, but it is better to use sandy loam with deep soil layer and organic matter. When newly planting, 20-30 kg of organic fertilizer, 1 kg of superphosphate, and 1.5 kg of potash are applied to each planting hole. You can also dig a hole to change the soil. The length of the hole is 80-100 cm wide and the depth is 60 cm. The backfilled nutrient soil can be prepared according to peat:organic fertilizer: topsoil=2:2:6, and 500 grams of compound fertilizer per hole is added. Evenly fill in the hole. The backfill of the nutrient soil is 5-10 cm above the surface of the soil and it is planted after the soil fertilizer sinks.
Transplanting Seedlings: The cultivation of greenhouse mist in the Beijing suburbs should be carried out in mid-April. In addition, it can be planted in the high-temperature and rainy season of July-August. The row spacing is 2m 3m or 3m 4m and the number of plants per acre is about 60-90.
Out-moulded seedlings are fully watered before planting under shade or under shade, and then restored after 5-7 days of restoration. After planting, build a tree plate around the plant, and then immediately root water, after infiltration, require the roots of seedlings and the ground. The tree tray is best covered with straw mulch to moisturize, and cover the shade net, in order to facilitate the slow seedlings.

Adult trees grown in northern greenhouses are usually dominated by nitrogen fertilizer (50% of the total) in mid-April, with phosphorus and potassium fertilizers (25% of the total); phosphorus and potash fertilizers are used in flower and fruit crops in mid-July (total) The amount of 25%); After mid-August harvest, the fruit was harvested and combined with nitrogen, phosphorus, and potassium fertilizers, which accounted for 50% of the total, plus 10 kg of compost. For a long time, nitrogen, phosphorus and trace elements can be sprayed on the leaves during fruiting.
Flower and fruit management: There is more flowering of lotus mist, and there are also many fruit set-ups. The fruit should be sparsely blossomed and thinned, and the fruit should be selected to leave a good result and the fruit should be enlarged and the quality improved. The fruits were bagged 20 days after flowering.
Temperature and humidity management: The optimum temperature for the growth of lotus mist is 25°C to 30°C, and the minimum temperature in the winter shed should be maintained at more than 10°C to facilitate growth and flower bud differentiation. Flowering shed temperature should not be too high, the highest not more than 28 °C. Lotus mist hi humid climate, increase air humidity can promote flowering results.
Pest control: Insect pests mainly include aphids and scale insects; diseases mainly include anthrax and fruit rot. Lotus fruit fruit is more sensitive to pesticides, and attention should be paid to the use of low-toxicity and high-efficiency pesticides.
