Longan First, the phenophase: (a) the results of the tree: fruit rapid large period of the second physiological deciduous period and the first summer shoot pumping hair growth period. (B) young tree: mature spring shoots, summer shoot pumping period. (C) planting trees: the first new shoot mature stage. Second, the key workers 怍: thin fruit Paul fruit, fertilizers promote shoots, spray Paul shoots. Third, the main pests and diseases: stink bug spawning incubation period, scarab, leafhopper damage to the emergence of a large number of young shoots, the first-generation larvae of the proposed small yellow leaf roller began to damage young leaves, moth borer began to eclipse shoots tender leaves and young fruits , Corner clip psyllium damage to young leaves (for the second peak). Fourth, the relevant technical points (a) the results of the tree: 1, after Xiehua to “and grain period” 1 to 7 days and 10 to 15 days, spray 0.3%
