Soil, fertilizer and water management Drainage This month, the concentration of rainfall is relatively high, and it is extremely important for the drainage in the park. Check the situation of stagnant water at any time, clear the ditch, and reduce damage to the root system due to accumulated water, high temperature, and excessive humidity. Weeding must be done when weeding grass is more than 30 centimeters. Weeding can be done manually or mechanically, and the weeds that are cut off can be covered with ridges or moistened to cool the tree trays. Herbicides should not be used as much as possible. During the drought-proof period, the temperature was too high, and the evaporation of water in the tree was too large. As a result, the tree vigor weakened due to loss of water, and the leaves prematurely fell off. According to the actual situation should be taken to drought and moisturizing measures (watering, covering). During this period of time fertilization continued to increase fertilizer. Hanging fruit trees use high-potassium compound fertilizer 150-200g/plant, young trees can use high-nitrogen fertilizer 2 times, the amount of 100g/plant, fertilization interval of about 20 days. At the same time, the continued use of foliar fertilizer is also the key to keeping the leaves. Preparation of autumn basal fertilizer: self-made organic fertilizer requires a sufficient process of decomposing, and it can take high-temperature stacking for 2 to 3 months, and it will be piled up once. Can be combined with oil withered, phosphate fertilizer, etc., according to the actual situation can be appropriate application of appropriate amount of compound fertilizer. Application time: can be started in September, the latest in December. Tree Management Bao Ye pays attention to drainage, drought resistance, application of phosphorus, potassium and amino acid foliar fertilizers, and repairs high temperature damage to trees and leaves. The buds are trimmed in the early autumn with suitable shoot positions and can be used to enrich the tree structure. The remaining parts can be erased (including buds that germinate in late autumn). For the overly thick tree of the leaf curtain layer, proper pruning will be carried out to achieve ventilation and light transmission, so as to increase the tree's effective demand for light and heat and enhance fruit quality. Picking up and falling fruit Pick up fruit once every two weeks and take it out of the park. Pest control Diseases that are of particular concern are: brown spot, anthrax, black spot, and canker; pests include: two-spotted spider mites, Spodoptera litura, second generation chafer, and scale insects. Prevention methods are as follows: 1, physical control: insecticidal lamp, artificial capture. 2. Chemical control: In August, use 25% of 14% Fuchs (chlorinated chlorofluorocarbons) or 2000 times of A-dimensional salt +29% of green wolfberry; 20% of wolfberry 2000 times + 40% of fluorosiliconazole (Fuxing) 8000 Times; Hongyang fruit picking, focusing on the prevention of bacterial diseases, with 1.5% thiazolyl (bacterial off) 500 times; 20% ronacillus (thiaca copper) 500 times; 33.5% quinolinone 1200 times. There are two preventions available for ulcers. One Step SARS-CoV2(COVID-19) IgG/IgM Test IgG and lgM antibodies to 2019 Novel Coronavirus can be detected with 2-3 weeks One Step SARS-CoV2(COVID-19) IgG/IgM Test Kit NINGBO AUTRENDS INTERNATIONAL TRADE CO., LTD , https://www.metests.com
after exposure.lgG remains positive,but the antibody level drops overtime.
