Postharvest Management of Waxberry

1. Scientific fertilization of bayberry trees consumes a lot of nutrients due to shoot growth and flowering in spring and summer. Flower bud differentiation and autumn shoot growth are in July and August, and autumn shoot growth directly affects the yield of the coming year. The amount of fertilizer application should depend on the strength of the tree and the amount of fruit, the general plant yield is more than 50 kg, the application of organic fertilizer 40 Mel 50 kg, 1 kg phosphate fertilizer mixed with 0.5 kg urea. Red bayberry should not apply phosphate fertilizer alone so as not to reduce the quality of red bayberry. Fertilization methods: (1) Ring fertilization: take the trunk as the center, dig the ring ditch according to the crown size, apply organic fertilizer ditch should be deep, cover the soil after fertilization, big tree fertilizer can be used this method. (2) Hole application or radial application: take the trunk as the center, balance with the arc around the crown, dig 5-30CM 6 grooves, the length and depth of the ditch depend on the amount of fertilizer used and the size of the crown, or the trunk can be centered, perpendicular to the tangent around the crown, dig 7 radial trenches, ditch length 70-80CM, width 30-40CM, deep 30CM, cover soil after fertilization. 2. In order to control the occurrence of bayberry brown spot, 200 times Bordeaux solution, 800 times 70% thiophanate methyl, or 1000 times more than 50% carbendazim can be sprayed after fruit picking. 3. After proper ploughing red bayberry harvest, due to trampling on the orchard and leaching of spring rain and plum rain in the harvest operation, the soil can be cut off by ploughing and loosening the soil, and the drought resistance of the tree can be improved from July to August. it is beneficial to flower bud differentiation and fruit in the second year, and the tillage depth is about 15m, which can be carried out together with fertilization. 4. Reasonable pruning of red bayberry in summer can ease the tree potential, so while applying topdressing, reasonable pruning of bayberry fruit trees, removal of disease and insect branches, withered branches, weak branches and shade branches, proper opening of skylights, ventilation and light of the crown, more autumn shoots, and increase the yield of autumn shoots.
