Strengthen management of mulberry fields affected by floods
1. Drainage and drainage. For the stagnant water mulberry garden, it is necessary to clear the ground quickly, clear the water system, and eliminate the alum, so that two rows of mulberry trees can be connected to each other, and the rivers can communicate with each other to ensure smooth drainage and irrigation. At the same time, we must prevent dark stains, lower groundwater levels, and improve the mulberry microclimate. 2. Chase fertilizer material. Timely strengthening of fertilizer management, supplementing fertilizing materials with quick-acting fertilizers, supplemented with appropriate amount of organic fertilizers, enhances the disease resistance of mulberry trees, and improves the quality of mulberry leaves. Supplemental fertilization materials should be applied twice. The first application of ammonium bicarbonate 50kg/mu, the second application of 25kg/mu urea, combined with 0.5% urea dilution of the mulberry garden treatment, spraying once every 7 days, continuous spraying 2-3 Times, to promote the restoration of mulberry trees as soon as possible. 3. Get rid of weeds. When the field is slightly dry and easy to loosen soil, assault weeds to improve the mulberry soil permeability. Artificial weeding should be adopted as far as possible on the weeding method. When necessary, the middle mulberry field can be sprayed with chemical herbicides, that is, using 10% glyphosate 500g per acre to dilute 75-100 times, and adding 0.15-0.2kg of detergent. Spray the weed stems and leaves as an adhesive. Note that the spray must be pushed down and the spray must not be sprayed onto the mulberry branches and shoots. Root mulberry groves or low-low mulberry groves should not use herbicides, but artificial weeds should be shallow, and the depth should be 10-13cm or so, and should not be too deep, in order to avoid damage to mulberry roots that are in recovery period. A small number of mulberry trees that have fallen down due to the impact of the storm will have to restore their strength to restore their tree potential. 4. Prevent pests. For the current mulberry field, the first generation of mulberry insects in the field exceeds the historical years, the control agent is mainly based on mulberry plants, 40% sangbao EC 3,000 times, and 60% equine EC 1000 times (or 40% mulberry EC 1000) Fold) For pest control, the mulberry garden for feeding summer silkworm should use mulberry medicine within one week of residue period and use pesticides for dicing. From July to September, Mulberry Garden was regularly inspected and found that the disease was prevented and treated with pesticides in a timely manner. 300-500 units of oxytetracycline and 100 units of agricultural streptomycin were used alternately in the early stage of disease to prevent and treat young shoots every 7-10 days. Repeat once, 4-6 times in a row to control the progression of the disease. The main products of basic chemical industry, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride and chlorine gas, are mainly produced with industrial salt as raw materials. In addition, also used in soap manufacturing, ceramic, glass production, daily chemical, oil drilling, drilling fluid, completion fluid, petrochemical dehydrated liquid, early strength agent, construction industry in the production of coating latex coagulation agent, curing agent, rubber industry papermaking additives and waste paper deinking, chemical industry of inorganic chemical raw materials and sulfuric acid root removal agent, the curing agent of alginic acid sodium, the prevention and treatment of wheat, apple, cabbage, such as decay and preparing food preservatives, metallic sodium and other sodium compounds, such as steel heat treatment medium. Salt is also widely used in water treatment, road snow removal, refrigeration and refrigeration.
