Breeding method of Chunmeng Dian brocade
Chunmeng Dian Brocade has become a popular variety collected by meat lovers due to its unique variation characteristics of spotted brocade. This Chenopodium plant of the family Crassulaceae has yellow and white markings randomly distributed on its leaves, forming a natural art painting. Mastering scientific breeding methods can not only maintain its ornamental value, but also promote the healthy growth of plants. The following will comprehensively analyze the key points of conservation from environmental regulation to pest and disease control. The four core elements of Chunmeng Temple Brocade maintenance are temperature and light precise control. Chunmeng Temple Brocade grows best at 18-25℃, and needs to be maintained above 15℃ in winter to prevent frostbite. If it exceeds 32℃ in summer, it will enter a dormant period, so it is recommended to move to the north-facing balcony. Direct light for 4-6 hours a day in spring and autumn can enhance the color rendering of the brocade, and use a sunshade net to control the summer light intensity within 20000Lux. Smart water supply techniques use the "alternating dry and wet method" for watering: dip the basin for 15 minutes every 7 days in spring, and change the summer hibernation period to spray water for 20 days. Keep the moisture content of the substrate <30% at low temperatures in winter. The bamboo stick insertion method can be used to detect the humidity, and replenish water when the tip of the bamboo stick is only slightly wet. Scientific fertilization plan The cultivation method of Chunmeng Dian brocade
During the growth period, nitrogen, phosphorus and potassium balanced slow-release fertilizer (NPK15 -15-15) is applied monthly, combined with foliar spraying of calcium and magnesium fertilizers every quarter. Plants with more than 50% of the spotted brocade parts need to reduce the amount of nitrogen fertilizer and switch to high-phosphorus potassium fertilizer (NPK5 -10-10) to prevent brocade fading. Advanced Breeding Management Skills Select healthy leaves in the middle and lower parts of the entire process of leaf cutting and breeding, and use a disinfectant blade to cut obliquely 45°. After drying for 3 days, lay it on a substrate with perlite: vermiculite =3:1, maintaining the environmental humidity of 70%, and the temperature of 22-25℃. Spray water was used to form calli 21 days later, and the new buds were transplanted after reaching 1cm in diameter. Operation points for basin replacement When basin replacement is carried out every spring, 70% granular soil (red jade soil: deer marsh soil: volcanic rock =3:2:1) is mixed with 30% peat soil. After pruning, retain 3-5cm of main roots, soak in carbendazim solution for 20 minutes, dry, and place in a pot. After changing the pot, place in a scattered light place to slow down the seedlings for 15 days. Systematic pest control (T-J) integrated disease control
