Honeysuckle is picked from April to July every year. Practical experience has proved that the management of honeysuckle after stealing flowers is an important countermeasure to promote the rapid repair of main stems, take more autumn shoots and improve the next annual output. Flower farmers in all countries of origin should attach importance to this work. The main management methods of honeysuckle after harvest are pruning, garden cleaning, liquid fertilizer management and pest control. The specific practical operation can be introduced in detail as follows.
Cultivation techniques and methods of honeysuckle.
Pruning of honeysuckle
Pruning method 1: Thinning: Thinning branches with serious diseases and insect pests, dry branches, dense weak branches, cross branches and blind branches with unreasonable planting positions. The purpose is to reduce the consumption of excess nutrients and water volatilization. Pruning method 2: cut off part of the original branches. Produce strong new buds and make the trunk compact and full. Pruning method 3 Retraction: A method of pruning branches that have grown for many years. Pruning method: the newly planted or partially pruned branches of fruit trees are not pruned and allowed to grow and develop. Garden cleaning method of honeysuckle
Many honeysuckle growers failed to ensure timely clearing of the garden in the management methods of honeysuckle, which aggravated the disease and reduced the yield. Therefore, on the one hand, it is suggested that flower growers immediately pick out the branches of diseases and pests, prune them and bury them, on the other hand, they should pick out the dry branches, dense weak branches, cross branches and blind branches with unreasonable planting positions outside the garden to solve them. After clearing the garden, the whole garden will be carried out once, and 75% triadimefon or 15% triadimefon water will be sprayed per mu to reduce the occurrence of pests and diseases. Management method of liquid fertilizer for honeysuckle
Ridging and weeding: For those who have not planted all crops after harvest, ridging and weeding should be carried out once to improve the charm of rhizomes and reduce the growth and development of weeds. Topdressing: Because most nutrients of honeysuckle have been taken away after flowering, in order to quickly repair the plant type and improve the main nutrient content, one-time topdressing chemical fertilizer is needed, and the key is to take organic fertilizer and carbohydrate compound fertilizer as the leading factor. The amount of fertilizer applied depends on the size of the cluster. In general, organic fertilizer 1 kg and carbohydrate compound fertilizer 2-4 are applied to each tree. Fertilization should be applied in the circle around the plant cluster, and then filled with soil to prevent the outflow of chemical fertilizer. Control of honeysuckle pests and diseases
Harm of honeysuckle downy mildew: the key harm to leaves, the disease spot is a little milky white, and it develops into milky white toner spot in the middle and late stage, and the whole leaves are covered with milky white toner layer. In severe cases, it will turn yellow and deform, and the flowers will twist and fall off.
Prevention methods of honeysuckle downy mildew
Moderate plastic and cosmetic pruning, immediately carry out diseased branches, diseased leaves, pruning branches, dry branches and dead leaves. Before the onset, 75% Antaisheng Granule100g water and 50-60kg sprayer were used to control new buds. At the beginning of the disease, 30g of 5% fluorosilicone +75% Antaisheng wettable powder100g or 43% Li Hao granule100g +75% Antaisheng wettable powder100g or more than 80% Heng Lv were used per mu. Fu. 40g of zinc (No.2) wettable powder and 50-60kg of water sprayer, every 10 day 1 time, lasting 2-3 times. 10- Take the medicine once half a month before harvesting, and pesticides are prohibited in flowering period. Harm of honeysuckle brown spot disease
Focus on leaf injury, brown spots appear on the leaves in the early stage of the disease, and dark brown annular spots or irregular spots appear in the middle and late stage. Pests and diseases began to occur at the end of April, and the incidence was heavier from June to August.
Control method of honeysuckle brown spot disease: 800 times solution of 70% thiophanate-methyl wettable powder or 800 times solution of 70% mancozeb wettable powder per mu, spraying 1 time every 7 7- 10 days for 2-3 times continuously.
Harm of scarab to honeysuckle.
In addition to biting the main roots and stems, larvae cause serious damage from April to May and from late August to early September.
Prevention methods of scarab
Carry out human hunting and light spraying to prevent the application of farmyard manure without composting and reduce the total amount of eggs laid in nymphae fields. Detoxification from the middle and late March to the middle and late April, and from the middle and late August to the middle and early September. 1 mu 10% diazinon tablets mixed with 20 kg toxic soil or 1 mu mixed with 20-25 kg fine soil with 200 g 40% diazinon EC. After deep application, cover. Root irrigation: When grubs are out of the field, root irrigation with 480g/L chlorpyrifos 1000 times solution or 40% diazinon EC 1000 times solution can kill the larvae around allelopathy. Harm of budding insects to honeysuckle;
Most of them are gradually produced in early, middle and late April, and the insect situation is heavier in May-June. Focus on damaging the buds and vine tips of honeysuckle, causing curling, endangering growth and development, and causing low yield of honeysuckle.
Aphid control method
Spraying omethoate 1 time before the main stems germinate to kill the winter buds. From the middle and late April to the middle and early May, 24 ml of 10% pymetrozine granules or 6 g of 70% van Schell water dispersible granules or 70% Heng Lv acetamiprid wettable powder were used per mu, and 50-60 kg were sprayed on the leaves. 10- pesticides should be banned half a month before harvest. 10kg of water can be sprayed with soap powder 1 kg or100kg of water and ethanol lKG.
