maintenance management
1, location: Lycium barbarum should be placed in a sunny place. If it is placed in the shade, it is not conducive to flowering and fruiting. Avoid direct sunlight in summer, can resist cold in winter, and can overwinter in the open air above-10℃.
2, watering: usually watering should alternate between dry and wet, according to the principle of no watering, watering should be thorough. In the flowering and fruiting period, we should pay attention to proper watering to prevent it from being too dry or too wet.
3, fertilization: thin fertilizer should be applied frequently, leaves should be picked in early summer and autumn, and a little thicker fertilizer can be applied each time to promote the birth of new leaves and buds. Proper fertilization can be applied before germination and after fruiting, so that the fruit is huge and the plant is strong. Don't apply too much fertilizer and chemical fertilizer during flowering.
4, pruning: every winter and spring for big pruning and plastic surgery. Cut off diseased branches and dense branches at any time at ordinary times and keep a certain tree shape. Take out the sprouts in time.
5. Turn the pan:1-once every two years, preferably in early spring. When turning over pots, removing half of the old soil and replacing it with loose humus-rich culture soil can reduce the application of base fertilizer. Cut off dead roots and some long and old roots. It's very important to turn over the pot and change the soil. The failure to turn over the basin for many years, the soil of the basin is hardened and the drainage is not smooth, which seriously affects the tree potential.
6. Pest control: The main diseases of Lycium barbarum are powdery mildew and black fruit disease, which can be controlled by Pomei 0.3-0.5 sulfur mixture. At the initial stage of the disease, carbendazim, carbendazim, mancozeb and triadimefon can be used alternately for prevention and treatment. The main pests are aphids, psyllids and sarcophagoides pteronyssinus, which can be controlled by spraying 90% crystal trichlorfon solution, 50% phoxim EC, 40% omethoate and mirex. The key is to master time and concentration.
