1. Select high-quality, disease-resistant seed varieties. To phase out the existing second-generation, third-generation and other generations of old varieties, use the Netherlands, Hailin, Timlin, Gao Lin, Pakistan Greenland, the United States Atlas, Glenn Weizhi, emperors and other generation of disease-resistant varieties. These varieties have developed root system, high yield and high quality. 2. Choose suitable soil for planting. Asparagus likes good ventilation, slightly acidic loam (PH value 5.8 ~ 6.7), sandy soil with salt content of not more than 0.2% is appropriate. The soil in the planting area is loose, the soil is deep, and alluvial soil or fine sandy loam soil is rich in organic matter. 3. Strengthen fertilizer management, scientific fitness cultivation. We should do a good job in the basic construction of farmland, drain water, reduce groundwater level and humidity in the field, and improve the growth environment of asparagus. During the growing season, it is necessary to apply precipitative fertilizer, strong growth fertilizer and autumn fat fertilizer. The ratio of N, P and K is 5:4:4. Organic manure, biological fertilizer and chemical fertilizer are combined to increase organic manure. Attention should be paid to the use of farmyard manure. , wolfberry, fermentation and other harmless treatment. The foliar fertilizer can be sprayed once every 7-10 days during the harvest period, which can not only enhance the resistance of plants, but also increase the yield and improve the quality. 4. Clear the garden in time to eliminate the source of the disease. After harvesting the asparagus in the spring and autumn seasons, the weeds in the field must be removed in time after the winter stems are wilted and removed from the field and burned. After entering the winter, you can open the topsoil and loosen the boring bed to expose the larvae and maggots of the pathogens, so as to facilitate killing, freezing, and elimination of most of the diseases and insects. During the growth period of asparagus, it must also be inspected. The pests should be cut off in time and burned outside the stove. It is strictly forbidden to discard or pile up near the field. 5. Pharmaceutical control principles (1) Select the appropriate agent and dosage. Different pesticides were alternately used, and the right medicine was used. The concentration of the liquid should be changed due to the season and the age of young shoots. (2) to master the time of spraying, generally spraying in the afternoon 4 to 5, the high temperature at noon, water evaporation, easy to produce phytotoxicity, windy and rainy days do not spray. (3) Strictly ban high-toxicity and high-residual pesticides, rationally use pesticides according to the guidelines for the safe use of pesticides, and vigorously promote biological pesticides and low-toxicity and low-residue pesticides. (4) Do a good job in predicting and forecasting pests and diseases and implement the principle of group prevention and group management. For a concentrated bamboo shoot garden, it is best to implement uniform deployment, uniform time, unified actions, and uniform drug control. 6. Chemical control methods (1) Soil disinfection. After clearing the garden in winter, the ground spray was disinfected with 70% mancozeb WP (wettable powder, the same below) 600 to 800 times or 75% chlorothalonil WP 600 times, and 1125 kg/ha of lime powder was applied to the soil. disinfection. (2) Disease prevention and control. Common diseases of asparagus stem blight, blight, root rot, etc., in the prevention of cultivation, emphasis on early use of drugs, strengthen the prevention and treatment of young stems, generally no disease field, when the first stem began to branch, Immediately spray conventional protective agents such as 70% mancozeb WP 800x or 75% chlorothalonil WP 600x. For diseased fields, and in the peak period of July, August, September, etc., a therapeutic agent must be sprayed, such as 12.5% ​​diniconazole EC 1500 times or 40% more manganese zinc WP 500 times spray control . (3) Pest control. The prevention and control of thrips can be controlled by 10% imidacloprid WP1500 ~ 2000 times liquid, nocturnal insect pests can be used 5% Dingchong Long EC (commodity name CPT) 1000 ~ 1500 times liquid. To control underground insects such as earthworms and floorworms, use 90% crystal trichlorfon, 1.5kg/ha to dissolve in small amounts of water, stir in fried peanut cake, make bait and seduce at night. All insecticides should be used reasonably and strictly at their safe intervals.
Meat more than we raise chicken, Turkey, stout, fleshy structure and nutrition ratio more reasonable, in the soil chicken contains rich protein, trace elements and a variety of nutrients, fat content is low, have important value for our human body health, is our Chinese people prefer meat products, belong to high protein meat.Native contains rich amino acids, amino acids for human body has a very important role, he is to make up our human body protein and related to the life activities of the most basic material, is in the biological constitute the basic unit of protein molecules in the body, is our basic material life, there is a close relationship to human life activities. It is an indispensable nutrient in our body. These nutrients in Turkey are very important for the growth and development of our bodies.
