Litchi is transferred to the main pests and diseases during the collection period. The pests include litchi and locusts, cockroaches, borerworms, and fruit-feeding tobacco moths. The diseases include downy mildew, anthrax, and acid rot, and they need to keep up with management measures. Technical operation At present, the main task of Litchi is to restore tree vigor and cultivate autumn shoots. 1 of the early maturing varieties of autumn has been released, can not be short cut, so as not to affect the quality of autumn shoots, but can be properly removed too dense branches. 2 It is necessary to timely spray and protect new shoots. 3 To make full use of the recent rain, especially the lack of water in the mountain orchards, pay close attention to fertilization, put 1 more autumn shoots. 4 There is no organic orchard orchard. Fertilizers are to be prepared and will be applied in late July or early August. 5 In order to accelerate the ripening of shoots, spray the polynucleotide once when the leaves begin to turn green. The second or third autumn shoots of mid-maturing varieties have been drawn out or are beginning to mature, but some orchards only have 1 autumn shoot. 1 The orchard with no results has been removed from the second or third shoot, fertilized with soil or sprayed with a polynucleotide on the foliage to promote shoot growth. 2 For an orchard that has only released one autumn shoot, you should pay close attention to your time. 3 Regardless of the current release of the first few autumn shoots, care should be taken to spray the tip of the spray and fight for the last autumn shoot in late September and early October. 4 There is no orchard orchard applied at the latest in late August. Appropriate application of phosphorus and potassium fertilizers will be added. Late-maturing varieties seize time for fertilization and pruning. 1 In order to restore the tree vigor, the first fertilizer is applied after the fruit is picked, nitrogen fertilizer is the main fertilizer, and hair growth is promoted when promoting new shoots. 2 After fertilization for 5 to 7 days, the buds have begun to sprout and can be trimmed, especially for more trees. 3 When the disease or pest in the orchard is severe, the lime may be applied once after the fruit is harvested, and soil may be turned into soil to improve the physical and chemical properties of the soil, increase the soil fertility, and reduce the occurrence of pests and diseases. One set of prevention and cure package: The potential is like bamboo (13% high-chlorine triazophos) 1500 times + Heilier green micro (2.5% kung fu) 1000 ~ 1500 times + Addi (0.5 methoquinone salt) 1500 times + luke (50% ene Acylmorpholine) 1500 times. Package two: black light (25% Prombromo-Metoprol) 1500 times + Jin Ming (3.2% Meth salt high chlorine) 1500 times + Luke (50% Dimethomorph) 1500 times. Precautions 1. Absolutely disable highly toxic and high residue products when close to fruit harvest. 2. In case of rainy weather, shorten the interval between spraying and pay attention to sunny spraying. 3. The fruit-feeding moth can be evaded by sticking the wet citronella paper at night, and the bat can be killed by the net. 4. During this period, it was mainly to control peduncle and downy mildew. According to the characteristics of strong pathogenicity, short incubation period and frequent re-infestation, the bacterium should be mainly controlled by pesticides. In combination with field disease prevention, comprehensive control measures such as low temperature after picking fruit and antisepsis are taken.
