Ginger cultivation is a good project for farmers to increase their income, but it often appears that rotting ginger sprouts in production, and Jiangnong can't prescribe the right medicine. Experts believe that the causes of bad ginger dead seedlings are as follows. I. Diseases of ginger borer Mostly caused by seeds and soil bacteria, prevention did not keep up. The prevention method is as follows: 1. Sowing seeds: After the ginger seeds are harvested, they are sunned for several days, and then placed at 20°C to 30°C for 7 to 8 days to promote wound healing, which can reduce the occurrence of ginger aphid during storage. 2. Soaking: Choose ginger, rich plump, bright skin, fresh meat, hard texture, disease-free ginger for ginger. Before germination, use 0.2% borax + 0.5% potassium dihydrogen phosphate + 50% carbendazim 800 times + antiviral 800 times + Tianda 2116 dip and seed special 600x liquid soaking for 15 to 20 minutes. 3. Avoid continuous cropping: Ginger roots are underdeveloped, continuous cropping of roots is small, and rot is easy to occur. Therefore, it should be carried out for 3 to 4 years with rice, cruciferous plants, and leguminous crops. 4. Soil disinfection: 75-100 kilograms of lime are sprinkled per acre for soil disinfection. 5. Post-mortem treatment: The diseased plant was found to be removed in time, and lime was sprinkled in the diseased hole. Quantian uses 500 to 600 times the anti-virus scorpion + Tianda 2116 underground rhizome-specific 600 times or 72% of agricultural streptomycin 100 units irrigated. Prevent the irrigation water from sick fields from flowing into disease-free fields. Second, excessive fertilization and improper fertilization caused by fertilizer damage Some ginger farmers believe that ginger is resistant to fertilizer, and the more fertilized the higher the yield, so blindly replanting chemical fertilizers, partial nitrogen fertilizers, concentrated fertilization, and some even dry urea, compound fertilizer, resulting in fertilizer damage, hemp ginger and severe rotting Dead ginger seedlings. Ginger should be treated with mature farmyard fertilizers. Generally, 3,000 kg of cow manure, 30 kg of superphosphate, and 15 kg of potash are used as base fertilizer per acre when the soil is prepared. When the seedling height is about 30 cm, a fertilizer is applied. Pig manure water 750 ~ 1000 kg; before and after the summer solstice ginger seedlings to 3 ~ 4 seedlings, per acre with cooked dried cake 50 ~ 100 kg mix gray ash 300 ~ 500 kg, or apply pig manure water 1000 ~ 1500 kg, fertilization cover A layer of fine soil or soil slag; Before and after the summer heat, 1000 ~ 1500 kg of pig manure per mu, 4 ~ 5 kg of urea. Third, the water caused by flooding in the field Due to shallow soil cultivation, shallow drains and white sandy soils caused by air leakage caused by waterlogging, waterlogging caused by high temperature and humidity caused rotten ginger seedlings. Prevention methods are as follows: 1. Before the frost, dig 35 to 45 cm deep in the ginger field; at the same time, dig the main ditch with a depth of 55-60 cm and a ditch depth of 50 cm, so that drainage is smooth, the rain stops, and the ditch is planted. No water or dark stains in the nest. 2. Choose loam and clay loam with deep soil layer, good air permeability, rich organic matter, strong water retention and fertility, and avoid white sand soil planting with easy-leaking knots. 1000Hz High Frequency LiDAR System JRT High Frequency Range LiDAR Sensor is 2021 new product, that's a low-cost tof sensor but High frequency (up to 1000Hz).
